THE MODERN AND THE PALEOZOIC, ALBERTA In 2013 the Bow River abandoned its original channel and established a new route closer to Tunnel Mountain, near Banff. As a braided river, the Bow will eventually reoccupy its old channel as it switches back and forth across the valley over time. Above the river is the north face of Mount Rundle comprised of the Late Devonian and Mississippian strata. The Tunnel Mountain Hoodoos lie in the foreground. Photo by: Kurt Armbruster.

h! Springtime in Alberta! Sun, snow, breakup, rain, sleet – all in one afternoon. And COVID-19 is still grimly holding on and keeping us apart. In this issue, we should be getting excited about attending the 2021 GeoConvention and Meltdown – but sorry. Postponed until September, when Dustin has a great show (virtual, of course) lined up for us. Maybe next year, given that this is a great ‘Next Year’ country.
Our science is far from static, despite our current coronal virus constraints. We would all like to improve our knowledge of what is coming out of the field and laboratories around the world.
What we do have for you is a great e-zine lineup of articles to tickle your reading fancy. George Eynon reveals the third in his series of articles on the regulation of our professions and industry. Astrid Arts leads us through a walk in amongst the erratics and Kiersten Mohr introduces us to the Psychology of Geology (by golly, that would make a great rap riff). Jon Noad takes us on a virtual field trip to the South African Veld, asking “Black Gold: The World’s Oldest… and Richest… Oilfield?”. By the way, Kiersten conveys a Message from the CSPG Board as well as her feature article. Don’t miss either one. There is still a wealth of Technical Webinars and Technical Division presentations in this edition to build our Professional Development credits and spark our thinking. Our usual line up of GeoCommunity Talks are reported upon, as is our Industry Update. Society News includes a wrapup on the Gussow (virtual) Conference and the Medal of Merit winner citations.
While perusing this edition, take a couple of minutes to watch the Mountjoy Conference and Core Conference promotional videos, then plan to attend. Both events are coming soon, and we all want to get them into our calendars. On the subject of planning, if you have insights into important advances in geoscience and technology in progress or that have recently been revealed and would care to write up an article for the Reservoir, we plan to devote page space to those topics in our upcoming editions. Our science is far from static, despite our current coronal virus constraints. We would all like to improve our knowledge of what is coming out of the field and laboratories around the world. That sums up what we have to present to you in this edition of the e-Reservoir. Please let us know how we are doing and what you might like to see in the second half of 2021 and into 2022. In the meantime, enjoy springtime in the Rockies (and forests, plains, and other physiographic provinces!) n

MESSAGE FROM THE BOARD KIERSTEN MOHR, CSPG PUBLICATIONS DIRECTOR
The Publications Evolution: Enhancing Value for Our Members
2020
was a milestone year for the publication's portfolio after the successful and aheadof-schedule transition of Reservoir into a digital platform. We could not have executed this transition without the passionate dedication of CSPG's Emma MacPherson, who quickly and seamlessly worked behind the scenes to bring our digital version to life. Additionally, in 2020 we were fortunate to begin working with a contract designer specializing in digital content generation. This new relationship has put the entire process in our hands, allowing us to be incredibly responsive to member preferences and evolve our design and content delivery in real-time. As a long-time CSPG member, I am extremely proud of this evolution as it springs our society's magazine into the 21st century. Looking forward, I am confident we have set a foundation from which we can continue to evolve content, accessibility and engagement, ultimately allowing all of us to stay more engaged and connected to new ideas, insights and society news and events. As we looked ahead to 2021, the publications committee set our sights on the Bulletin of Canadian Petroleum Geoscience (BCPG). For over 68 years, the BCPG has showcased historical discoveries, exploration challenges and brought to life many leading-edge geoscience ideas and concepts. As with many other professionals, the BCPG was formative for me in building my technical competency as I took on various subsurface challenges throughout my career. This journal provided an open window into the concepts and ideas I needed to understand as I continually took on new and challenging problems in our industry. I will never forget the first issue I opened, and from that point forward, it became my go-to resource. As I have

RESERVOIR ISSUE 3 • MAY/JUNE 2021
spent the last year exploring the behindthe-scenes workings of this journal and the people who make it happen, I have been quickly reminded of how foundational this publication is to our society and how much pride I had in it as a Canadian Geoscientist. With that said, as we looked at the BCPG journal relative to current industry trends, comparative benchmarks, and feedback from current and potential contributors across the country, it was clear that the BCPG was facing many challenges. First, we had continually seen a decrease in our content submission. Our publishing process was slow and lacking the efficiency, consistency and timeliness of our peer publications, and the delivery options of our content were limited. Additionally, given the currently evolving roles of geoscientists across our country, we recognized that this publication's scope and name were unintentionally limiting our ability to showcase new and exciting geoscience for our members. In contrast to the challenges, the enormous benefit that was apparent was how many dedicated and passionate individuals were already in place and committed to helping our society reimagine and rebuild a journal that was and continues to be so meaningful to so many of us. Therefore, as we came to the end of 2020, the CSPG board committed to evolving the Bulletin and getting started. To begin with, at the end of 2020, working closely with our Editors-in-Chief, Dr. Jennifer Galloway and Dr. Hairuo Quing, the CSPG board of directors voted unanimously to expand the scope of the Bulletin to include all aspects of Canadian energy geoscience. Next, and most significantly, in the first quarter of 2021, the board unanimously voted to change the name of the BCPG to the 'Bulletin of Canadian Energy Geoscience (BCEG).' The current timeline
will see a call for submissions in Q3 of 2021, with our first issue to come on in Q1 2022. This change of scope and name is the foundation on which we will begin to build a more inclusive, relevant and meaningful journal for all of our members across the country and worldwide. The committee, publishing team, editors, and organization are all excited to be part of building the next generation of our Journal. While a name change provides the first step, many other improvements are necessary and will accompany our new name. First, in 2021, the publications committee will be bringing forward 'ahead of print publishing,' which will help ensure researchers can get their work out faster, and our members will be able to access content quicker. Next, we will be adding 'open access publishing options to maximize the optionality for contributors on submitting their content. With a great deal of excitement, I look forward to the future of our publication's portfolio. Like any transition, it can feel difficult at the beginning and complex and challenging in the execution. However, given the passion of so many individuals behind this portfolio, I am confident that on the other side of this evolution we will have created a modernized, inclusive and much more engaging publication which will work to connect our membership across the country with the incredible science going on in our discipline. As a long-time CSPG member and as importantly, a Canadian geoscientist, I can't wait to see where we go! Please check out our new scope and stay tuned for submission deadlines so you don’t miss your chance to be part of the first issue on this new path for the CSPG! n
The H.M. Hunter Award was originally created to recognize CSPG members who have contributed long term distinguished service to the Society. As such the focus was on volunteers more in the latter part of their careers and who likely had served in a variety of capacities. However distinguished service is not limited to long term service members, so the original concept has been modified to also recognize outstanding volunteer efforts of the Society's younger members. The H. M. Hunter Award now recognizes: • a longer term CSPG member (20+years) who has contributed to the Society on an on-going basis in a volunteer capacity in a variety of portfolios and/or singular outstanding service. This would include an outstanding individual who has not received a major service award recently and if they have been recognized in the past, have contributed to provide great service to the Society since that time. Special consideration is given to those 'behind the scenes' i.e. 'unsung heroes' whose contributions have not been adequately recognized. Such longer-term members have gone above and beyond and by doing so have promoted our profession and the Society. • a shorter term CSPG member (10-20 years) for exceptional performance, who has gone above and beyond, a rising star as a volunteer to the Society, and who has demonstrated an outstanding commitment to the CSPG.
Both awards are of equal merit and recognize exceptional volunteer commitment to the Society. The CSPG is built on a legacy of service by members and so strives to recognize and encourage such recipients. There is no restriction as to the number of times an individual may win this award. Nor does this award have to be awarded in either category each year or at all in the unlikely situation of no worthy nominees in a given year.
History of the H.M. Hunter Award First awarded in 2004, this award is named after Mr. H. (Harry) M. Hunter who was a founding member of the Alberta Society of Petroleum Geologists. He had one of the longest volunteer careers of the founding members. Harry Hunter served as ASPG SecretaryTreasurer in 1929, as Business Manager in 1935 and 1937, and as President in 1939. Harry Hunter was the only founding member present at the final meeting of the ASPG where they overwhelmingly agreed to change their name to the Canadian Society of Petroleum Geologists. This award is named in honour of Mr. Hunter's work in the early days of the Society, on the Executive and his subsequent volunteerism. The award is a wall clock chosen to represent the time members have given to the Society. The originator of the award, Astrid Arts, designed the original clock. The current version of the award is a plaque-style, slate, wall clock with the CSPG logo in the center and the name of the winner on a brass plate.

Jim Barclay Jim started his education and geology career on the hard-rock side of things. In 1979 he moved from mining exploration with Norcen Energy to the oilpatch with Dome Petroleum. There he quickly realized he needed to improve on his meagre soft-rock knowledge and he began using CSPG talks and conventions as his soft-rock school, absorbing everything he could at these events. That was his introduction to the CSPG. His CSPG volunteering began with the CSPG around 1986 while working at the GSC and he was able to present project results at conferences, workshops and talks. Since then, Jim has published about 35 papers, given about 40 formal talks, luncheon talks, posters and core displays as well as many informal talks at oil companies, universities and schools. Most of the papers and talks were given via the CSPG.

Jim has a B.Sc. from Carleton University and a Ph.D. from the University of Calgary (Fed Krause, advisor). His career in the oilpatch centred mainly on regional exploration mapping and also resource assessment, mostly in WCSB. He worked for a number of entities. Notable stretches were at Dome, GSC, Poco/Burlington and ConocoPhillips, all in Calgary. Later in his career he enjoyed working as a geological advisor and doing a lot of mentoring and teaching. These days he is not sure if he is unemployed or retired. He would like to acknowledge the many terrific friends and colleagues he met during his career and volunteered with at the CSPG. He would also like to thank the companies and organisations he worked for who allowed him time to volunteer in CSPG activities. And Jim has said often that he received more from volunteering with the CSPG than he has ever given to it!

Regulating the Geoscience Professions:
A series on the Complementary Roles of Regulators, Individual Professionals, Employers, Academia and Government George Eynon, PGeo FGC FEC [Hon] ICD.D Principal, geos - eynon & associates consulting inc Past-President, APEGA (Association of Professional Engineers and Geoscientists of Alberta) Associate, University of Calgary, School of Public Policy and Haskayne Business School
PART 3 of 4: The Role of APEGA, Other Regulators
and Academics
Reconciling APEGA’S Regulatory Obligations and Member Services Functions Some jurisdictions separate the regulatory role from the association (advocacy and member services) roles for some professions. In Alberta, the Law Society regulates the professionals under the Legal Professions Act, whereas the Alberta Branch of the Canadian Bar Association is the advocate for Alberta’s lawyers. Alberta’s Health Professions Act organises health professions into regulatory bodies called “colleges” that have delegated powers and authorities for self-governance. Some of the professions— the College & Association of Registered Nurses of Alberta and the Chartered Professional Accountants, for example—have both association and regulatory functions, and are comparable to the authors’ professional affiliations—APEGA and EGBC—in that respect. Regardless of how they are organised, regulation and member services are different functions and need to be somewhat separate. Regulation is the more important role as it embodies the purpose of the enabling legislation of our associations—the protection of the public interest and welfare.
10 R E S E R V O I R I S S U E 3 • M A Y / J U N E 2 0 2 1
Viewed from my varied career perspectives, and bearing in mind the obligations to which we as professionals must adhere, a number of shortcomings (and some strengths) are evident. One shortcoming is that many academics teaching applied geoscience or engineering are not registered professionals; and are not even members of engineering or geoscience faculties. Neither are many so-called “earth scientists, who teach subjects that fall within the definition of the geosciences. A colleague refers to this phenomenon as “capture of the geosciences” by nongeoscientists; and something that we should rightly concern ourselves over from a regulatory point of view. Commonly, regulation of the professions is reactive rather than proactive, and avoids the difficult role of “policing” compliance. Many professionals do not understand the concept of selfregulation. There is a significant lack of effective collaboration and communication among the various regulatory agencies on professional practices issues; and among the regulators, academia, and governments regarding (as well as between members and the public). Both can create problems for individual professionals in their work situations. Commonly, professionals do not interact sufficiently with stakeholders or the so-called “general public” on issues that directly affect them. Canada has highly respected governance and judicial systems.
It is of utmost importance that APEGA adheres to its mandate of protecting the public interest, as well as the five core principles of good governance— accountability, leadership, integrity, stewardship and transparency
Other Regulators
creating and maintaining a healthy corporate culture, and grossly mismanaging public funds and assets.
Several other agencies directly or indirectly regulate the professional practice of geoscientists working in oil & gas exploration and production. The Alberta Energy Regulator (AER) regulates the operations of the energy resources sector, including oil & gas exploration and development, much of which is geoscience and engineering. Similarly, the Alberta Securities Commission (ASC) must maintain and regulate a fair and efficient capital market and Occupational Health and Safety (OHS) is responsible for enforcing labour laws to protect workers. All these areas include the operating companies and their employees.
Three independent agency investigations into the AER led to new processes for Board and CEO accountability, improved staff relations, retraining, closer watch of executive expenses, and improved channels of communication between the CEO and Board and the Board with the Government of Alberta.
Agencies that regulate professionals control the right of admission to the professions. Entities such as the AER, ASC and OHS do not have the ability to determine who operates under their regulatory aegis. However, these agencies are responsible for regulating practice within the bounds set by their legislation and, like APEGA, are dealing with the conduct and impacts of professional practice by both individuals and companies. Although there is some collaboration and coordination among them all, there needs to be considerably more than exists currently.
Failure in Regulation can be Catastrophic Failures in governance can jeopardize the responsibility of regulatory authorities to protect the public. Since governments set mandates for regulatory authorities under their jurisdiction, it’s up to the former to mitigate the risk with effective oversight and legislation. Effective oversight relies on five core principles of good governance: accountability, leadership, integrity, stewardship and transparency. In practice, regulatory authorities need leadership, ethics and a culture committed to good governance; and require strong relationships with stakeholders, effective risk management, both internal and external compliance, and ongoing monitoring, evaluation and support. Unfortunately, jurisdictions do not always follow these principles and practices; and such was the case with the executive management and board oversight of the AER. Its controls and processes designed to protect against conflicts of interest failed dismally. The Board oversight and AER leadership significantly exceeded its mandate, establishing an affiliated consultancy, not
Above all, the Government of Alberta learned that when pursuing new and innovative activities, it must carefully define mandates; and that effective whistleblowing processes are vital to uncovering misdeeds. It is of utmost importance that APEGA adheres to its mandate of protecting the public interest, as well as the five core principles of good governance— accountability, leadership, integrity, stewardship and transparency—referred to above. And that we as APEGA Professional Members follow suit.
Teaching Ethics and Professionalism at Universities The public demands the highest standards of ethical conduct by scientists. Regulators expect companies—and their future employees—to operate within the rules and regulations governing their industry. Given such societal expectations, the first and perhaps the most egregious problem (since it comes at the start of the career path of young professionals-to-be), is the absence of education on ethics, professionalism, and workplace regulation in post-secondary geoscience curricula in Alberta and likely across Canada. Education in the ethics of academic research is an increasingly important component of the university training of scientists, given that funding agencies require training of graduate students in the responsible conduct of research. Although there is considerable literature on the subject for reference (for example, Mogk, D. & Bruckner, M., 2015), few faculty members have the requisite training or knowledge to teach about research and professional ethics effectively or mentor students. Just as important, is the lack of education of geoscience students regarding their professional obligations and conduct. Universities’ curricula rarely includes enough, if anything at all, on professionalism and ethics. Few faculty members teach ethics and

In the interests of protecting the health, safety, and welfare of the public, and the environment, it is essential for us all as regulated professionals to engage in career-long learning. professionalism effectively to their students. It is not clear whether they lack the knowledge and understanding or they do not see the need and benefit of incorporating ethics and professionalism into the curricula. Somewhat ironically, there is considerable emphasis on ethics and professionalism in the education of other, nonregulated industry professionals. It is an integral part, for example, of the Land and Petroleum Land Management Program course I teach at the University of Calgary’s Haskayne School of Business. This lack of an introduction to professionalism is hardly surprising, given that barely one fifth (the national average is 21%) of geoscience departments’ faculty members are themselves registered professionals. Only 22% of geoscience faculty members in Alberta are registered professionals (data from Carter, D.C., and Stewart, R.D., oral presentation, 35IGC, 2016), and most register only if they conduct commercial consulting assignments in their field. However, I believe that teaching ethics, professionalism, and workplace regulation in post-secondary geoscience (and engineering) curricula should be mandatory. Education Departments and Academic Institutions should consider adding requirements for faculty members to be registered. If teaching geoscience is not practising geoscience, what is it? Regulatory agencies recognise that the curricula do not provide the opportunity to demonstrate professional competency: this requires a supervised probationary period as a Member-in-Training (MIT) to qualify for a professional designation. However, there are jurisdictions that admit students directly to professional status without any work experience and supervision whatsoever—this is poor regulatory oversight, to say the least.
Regulating Engineering and Geoscience Most often, the role of the professions’ self-regulatory agencies in dealing with practice issues is reactive: responding to complaints about members, and only then investigating and disciplining as required. This was the primary, perhaps only, form of practice regulation initially, but is now inadequate; regulatory agencies across Canada recognise the need to improve in this area. APEGA is no different in this respect. We are several years into a program to strengthen our practice regulation through a much more proactive approach that includes practice reviews and inspections on a risk-assessed basis. Regrettably, a significant proportion of its geoscientist members seem not to understand that APEGA’s primary role—the raison d'être of the Engineering and Geoscience Professions Act—is one protecting the public through self-regulation; not providing a wide range of ancillary services to us as members. In return for our
12 R E S E R V O I R I S S U E 3 • M A Y / J U N E 2 0 2 1
professional membership fees, many, perhaps most, members expect a range of benefits and services that are more appropriately within the scope of their technical societies rather than their regulatory agency. (That is not to say that APEGA does not take advantage of our sheer numbers to provide some advantages in the areas of professional practice and individual ad liability insurance, for example.) Effectively policing ourselves to protect the public interest is the essence of self-regulation. We must not compromise the privilege of professional self-regulation with self-interest. APEGA is addressing misconceptions about self-regulation through direct engagement. Professional members in all jurisdictions need to understand the legal requirement to regulate the professions under their enabling Acts, and that its purpose is to protect the public interest—which we accomplish best through self-regulation of the profession by the profession—i.e., by each of us and our peers.
Continuing Professional Development The Continuing Professional Development (CPD) program is part of the Regulations under the Engineering and Geoscience Professions Act. Society's expectations have changed; the public demands greater accountability from us as professionals. In the interests of protecting the health, safety, and welfare of the public, and the environment, it is essential for us all as regulated professionals to engage in career-long learning. Mandatory CPD is common in many professions. In most provinces, the geosciences regulatory bodies already have or are moving towards mandatory CPD requirements; but reporting CPD to the regulator is not mandatory in all jurisdictions, and tracking it is highly variable. Consequently, enforcement varies considerably. APEGA recently acknowledged deficiencies in its compliance processes and is improving regulatory oversight of its CPD program. Perhaps the best way is to link our current CPD compliance—as a prerequisite—to our annual payment of our dues for registration and licensure.
Next, in the Final Part… I suggest an expanded role for our professionals in the area of stakeholder engagement, and a great deal more collaboration by Regulators, especially on professional practice issues. As well, I briefly discuss the roles and involvement of governments and the courts in regulatory. And finally provide some conclusions and policy recommendations. n
Honorary Membership is the oldest award bestowed by the Canadian Society of Petroleum Geologists. Any person who has contributed distinguished service to the cause of energy geosciences in eligible for membership as an Honorary Member. Recipients are persons who have made outstanding contributions to the society or geologists or other earth scientists who have made outstanding contributions to the cause of petroleum geology on a national or international basis. Past Presidents of CSPG are given honorary membership at the age of retirement with automatic consideration for honorary membership being given earlier (i.e. at the end of their three-year term) on the basis of the preceding criteria.
Professor Noel P. James is a most worthy recipient of CSPG Honorary Membership for his outstanding contributions to our understanding of carbonate rocks, especially important to the petroleum industry in Canada and internationally. Noel James is Professor Emeritus at Queen's University in Kingston Ontario where he teaches sedimentary geology. He received his B.Sc. (geology -1964) from McGill University, M.Sc. (oceanography -1966) from Dalhousie University and Ph.D. (geology - 1972) from McGill University. In the following years he worked in the oil business in Calgary, helped establish the Comparative Sedimentology Laboratory at the University of Miami, taught at Memorial University of Newfoundland, and has been at Queen’s University since 1986. He has been an Industrial Fellow at Marathon Oil Company research laboratories and a Distinguished Visiting Scholar at the University of Adelaide. His relationship to Calgary and the oil business goes back over 50 years to when he first worked as an exploration geologist and joined the CSPG. Since leaving
for academia, he has retained strong ties, working with colleagues on Devonian and Mississippian research projects, teaching yearly courses for petroleum geologists with Bill Martindale at the EUB, and sending over 40 honours undergraduate and graduate students to work in the industry. Some of these are now working in executive positions globally. A compulsive teacher, he has reveled in leading field courses to Australia, Western Canada, Newfoundland, Western Europe, Bermuda and throughout the Caribbean. At the same time, he instructed a wide range of undergraduate and graduate classes at both universities ranging from first-year geology to sedimentology to petroleum geology to the geological evolution of North America. He confesses that one of his greatest joys is standing in front of students while waxing poetic about the fascinations of geology and arguing concepts with each one of them. An addicted fledgling artist, his love has been to illustrate geoscience through graphic design, revealing complex concepts via simple dynamic illustrations.

His research concerns the sedimentology and diagenesis of carbonate sediments and rocks throughout geologic history. The rocks, because they are largely composed of components formed in seawater, can be repositories of unparalleled information about the history of our evolving planet. They are also critical repositories of paleobiological information, aquifers for fresh waters, host rocks for natural resources such as metallic ores and hydrocarbons, and storehouses of information about global change. Decoding critical information contained within ancient deposits has been, however, difficult largely because of biotic evolution and diagenesis of these commonly soluble sedimentary rocks. This conundrum is potentially overcome by studying systems of deposition in the modern ocean together with older but still comparatively, young lithified deposits whose components are relatively unchanged from those forming on the seafloor today. Initial research interests were focused on the dynamics of reef and carbonate platform growth as illustrated by the modern and Pleistocene of the Caribbean where he helped pioneer the use of research submersibles in reef studies and formulate depositional models for use by the petroleum industry. After a period studying Paleozoic carbonate continental margin evolution, he turned his attention to the cool-water carbonate depositional realm. His papers have received awards from SEPM (Society for Petroleum Geologists) as well as IAS (International Association of Sedimentologists) and he has co-edited books on Modern and
Fossil Reefs, Cool-Water Carbonates, Paleokarst, Facies Models, and Precambrian Limestones. Many of our members have at least one copy of the various editions of Facies Models. He has just finished co-authoring his second book on Neritic Cool-water Carbonates in and adjacent to the Southern Ocean, and recently, he has completed a textbook on carbonate rocks with Brian Jones. He has received the Steacie Memorial Fellowship from NSERC (Natural Sciences and Engineering Research Council of Canada), the Past-President’s Medal and Distinguished Service Award from the Geological Association of Canada (GAC) and has been AAPG and MAC (Mineralogical Association of Canada) distinguished lecturer. He was Vice-President (1989-1990), President (19941995) and is now Honorary Member of SEPM. He served on the Council of the Geological Society of America where he was an Executive Committee member. He has been a NSERC Killam Research Fellow, the Bownocker Medallist at Ohio State University, was awarded the Twenhofel Medal by SEPM, the Logan Medal by GAC, and the Sorby Medal of the IAS, all the highest awards of the societies. He is a Fellow of the Royal Society of Canada and has been appointed a Member of the Order of Canada, the Nation’s highest civilian honour. The reputation of the CSPG is greatly enhanced by bestowing Honorary Membership on such a renown, world-class carbonate sedimentary geologist. We are therefore delighted to welcome Dr. Noel P.

Calgary’s Glacial Erratics: at the Confluence of Geology and History By Astrid Arts & Gabrielle Abernethy
Alber ta’s glacial erratics have had an enduring influence on our cultural histor y. Against the backdrop of expansive landscapes, the largest of these stone blocks have wielded a psychic pull on inhabitants and visitors. James Hector, geologist of the Palliser Expedition, first repor ted on these large blocks of quar tzite in 1863: “...and 50 miles from the Rocky Mountains, there occur a ver y extraordinar y group of blocks of granite....These blocks are of great size, one having been estimated to weigh 250 tons. Although, lying in a line, miles apar t, they seem to consist of the same rock, viz., a mixture of quar tz and red feldspar...” (Palliser, 1863, p.221) Hector failed to piece together their source, though it was broadly understood by Hector and his contemporaries the erratics and the ‘drift’ of gravels upon which they sat were the work of glaciers.
LIMESTONE BLOCK SITTING ON FRESHFIELD GLACIER, ALBERTA_ NA-3551-84 The large size of the erratics and absence of striations indicate the blocks were carried on or near the surface of the transporting glacier, [NA-3551-84] by H.

Erratic: glacier-transported rock or boulder that differs from the local bedrock, may be embedded in till or occur on the ground surface.
Archie Stalker (1956) mapped out this narrow belt of boulders and worked to solve the myster y of their origin and manner of emplacement. He dubbed them the Foothills Erratic Train. Stalker was not able to identify the origin of the erratics but suggested enough criteria that, Mountjoy (1958) was able to decisively conclude Mount Edith Cavell in Jasper National Park was the source. The quar tzite erratics are composed of fine to coarse grained sandstones and pebble conglomerates. They are massive to cross bedded and have a distinctive light grey to pinkish hue. It was recognized early that the erratics were from the Lower Cambrian Gog Group, 540-512 million years ago. These rocks, derived from the mass wasting of cratonic metamorphic and igneous sources, were deposited in deltaic or shallow marine conditions. The coeval Cambrian Explosion, the evolutionar y burst of life that filled the oceans with all major animal phyla, is

captured by the diverse trace fossil assemblage found in this clastic succession. (Magwood, 1988) During the Wisconsin Glacial Maximum, a rockslide from the cliffs of Mount Edith Cavell tumbled onto the Athabasca glacier and travelled nor th-eastward down the valley before intersecting the south west advancing Laurentide Ice Sheet. When the two ice sheets collided, they were deflected south as glaciation advanced across the continent. When the glaciers melted, a 600+ km chain of erratics were stranded in their present positions along a corridor from Jasper National par t to nor thern Montana marking the boundar y of these two great ice sheets. The timing of coalescence between the Cordilleran and Laurentide ice sheets would help answer some anthropological questions. Was there an ice-free corridor during the last glacial maximum? Could there have been a pathway for

human migration from Asia, across the Bering Land Bridge, through an ice-free corridor and into the lower latitudes of the continent? Jackson et al. (1997) dated the emplacement of the erratics using cosmogenic 36CL exposure dating . T h ey determined the Foothills Erratic Train was deposited b e t we e n 11,000 and 18,000 years ago and suggested that coalescence FLUTE PLAYER MOTIF of the Cordilleran Photo Credit: Jim Henderson and Laurentide ice sheets was the maximum extent of continental glaciation in western Canada. Geological and anthropological evidence now suggests the ice-free corridor was a transient feature at best and likely not a feasible route for the earliest human migrations. Routes along the west coast of the continent are a more credible alternative for the journey of humans into Nor th America. (Jackson & Wilson, 2004). The ancestors of the Tsuut’ina, the Stoney Nakoda, the Cree, and the Blackfoot hunted and camped amongst the lush coulees and valleys of our region and exchanged peace and war amongst themselves before the first Europeans came to bar ter for furs. Some of their stories are older than the forests and the rivers themselves: stories of a nor thern land engulfed in ice and snow and mystical adventures, immor talized in the constellations, under taken by the animals to retrieve summer.

Ice Age, its maximum reached more than 20,000 years ago. The earliest passage of humans along the western coastal route bypassed the inhospitable nor th to settle first in South America and the southern United States approximately 14,000 years ago. As the ice receded and icy melt waters car ved into the dr y and cool grasslands, the animals came and the stor ytellers followed, gradually dispersing nor th of the 49th parallel. Four hundred generations of stor ytellers imbued their oral tradition with magic realism, accounting their obser vations in fantastical events meant to teach and immor talize. Wilfred Buck, from the Opaskwayak Cree Nation in Manitoba, is an Indigenous star-stor y exper t. A stor y shared with him by Indigenous Elders, recounts a time of perpetual ice and snow in the Nor th Countr y; it is the stor y of the Fisher, Ochek. The Fisher was tasked with retrieving summer, as the little summer birds had been bundled up and imprisoned, keeping it winter all the time. Fisher used his sharp teeth to rip open the bundle and released the summer birds. The man who had captured the birds came running after Fisher with a bow and arrow but Fisher jumped into the sky and climbed right to the stars. Today, the outline of the Fisher’s body is commonly recognized as the Big Dipper constellation, his broken tail the Dipper’s handle. (Buck, n.d.)
DISTRIBUTION OF ERRATICS IN THE CITY OF CALGARY
The star stories are old - a testament to the temporal reach of human obser vers to our glacial past. But, they are not isolated. Hopi stories of the Flute Clan traveling nor th to a ‘land of ice and snow’ may have evidence in pictographs found at Grotto Canyon, near Exshaw. A flute player motif and trapezoidal bodies found in the rock ar t panel of Grotto Canyon resemble southwest Hopi/ Fremont rock ar t imager y. The flute player motif is directly equated with Kokopelli, a trickster figure in the traditions of the Hopi people and a totem figure for the Hopi Flute Clan. (Magne and Klassen, 2002) Fast forward to a ‘recent’ ~11,000 years ago, to the first intrepid humans following Pleistocene horses and camels to the cool climes of Canada. These early nomads came and went; their pulses of advancement left in flakes of stone tools and hunting technology. Their early stories were inter twined with the stars but later peoples shifted their skyward gaze to the landscape and left their memories painted on the rocks. Red ochre, mixed with animal fat, was used to draw images and meaning on canyon walls, on cliff faces, in caves and in the hidden recesses of erratics. The pictographs were indelible reminders of spiritual journeys, their meaning best left to those original inscribers. Erratics, mysterious monuments sitting incongruent amongst the open prairie, were frequent sites of rock ar t. For many First Nations, rocks are ‘grandfathers’; the erratics were not simply impressive rocks but rather an ancient forebear meant to be revered and respected - intuitive location choices for ethereal imager y. Alber ta’s largest erratic, the Big Rock, at Okotoks, holds special meaning to the Blackfoot. Blair First Rider (2020), an Aboriginal Cultural Advisor for Alber ta Culture and a member of the Blood (Kanai) Tribe, has said of the Big Rock: “The Blackfoot used the site as a place of visitation, ceremony and documentation. Vision quests took place, and red ochre was used to record impor tant events and imager y—a battle scene, a hunting par ty—on the rock’s surface. ‘These pictographs are also stories, and that is how we recorded significant events that are connected to this landscape… These are our landmarks and place names; it’s our record in stone.’”

Split Rock, situated at the west end of West Nose Creek (Confluence) Park, near Har vest Hills Boulevard, bears no sign of pictographs, but its smoothed edges bear the mark of bison that once roamed the area and used the erratic as a rubbing stone, helping to shed their winter coats. The Rubbing Stone, aptly named by locals, on the east flank of Nose Hill Park, near the 64th Ave parking lot, also bears the polishing work of bison. The depression circling its base testifies to the centuries of dust loosened and blown away by bison hooves. Though no wild bison roam here now, their bones are found at the base of ancient bison jumps and amongst the fire broken rock of hear ths from pre-contact encampments that lie buried among Calgar y’s plateaus and valleys. Many archaeological finds within Calgar y provide evidence of hunting and camping as early as ~8,500 B.P. and Clovis points ~11,000 B.P. have turned up, the remnants of spear throwing hunters reliant on now extinct Ice Age mega-fauna including mammoth and long-horned bison.(The City of Calgar y, 2019) At the confluence of geology and histor y, is the city of Calgar y. At its centre, the Bow River bends southward where the meltwaters from the retreating Cordilleran
ice sheet dammed along the front of the Laurentide ice sheet. Where the Elbow river empties into the Bow, the Blackfoot Confederacy met and camped. The gathering spot was a natural choice to establish trade and For t Calgar y was built, later to become a population hub along the metal track that tied the new countr y of Canada together. It is here the erratics still elicit wonder and respect. The Big Rock west of Okotoks is the largest and most famous erratic in the train, but the city of Calgar y has a surprising number of large erratics wor thy of exploration. Valley Ridge, Sienna Hills, Paskapoo Slopes and West Nose Creek offer interpretive signs. The 500 tonne erratic in Panorama Hills inspired the naming of the Buffalo Rubbing Stone Elementar y School when it opened in 2017. And for anyone who has been a student at the University of Calgar y in the last 50 years, “The Rocks,” limestone erratics covered in thousands of layers of paint, are a communal message board for students to broadcast their opinions and to adver tise events. Their impor tance inspired a YouTube video produced by the University of Calgar y Alumni (2016) and can be viewed at: https://www.youtube. com/watch?v=hkmV1KfK1qQ

The Blue View: Industry Trends Through Woodmac's Lens NORTH AMERICA IN CONTEXT: OVERARCHING THEMES ACROSS THE INDUSTRY Resources merged with Seven 1. ARC Generations to create the largest pure-
play Montney producer, and sixth largest energy company in Canada. The company emerges producing nearly 20% of all wellhead condensate and pentanes plus production in Western Canada.
CANADA ONSHORE: n Canadian condensate shuffle
The condensate market in Canada has seen a recent shakeup both in the Duvernay and the Montney. On the Duvernay front, Crescent Point made a jump from the East shale Duvernay into Fox Creek by acquiring Shell’s assets. This deal provides Crescent Point with a decade of drilling inventory and will help offset their corporate decline rate from the mature Saskatchewan plays. This represents a changing of the guard in the Duvernay with Shell and Ovintiv exiting the play, being replaced by Canadian operators. In the Montney, a blockbuster merger deal was announced by ARC Resources and Seven Generations. The deal closed on April 6th and ARC emerges as the top condensate producer in Western Canada, accounting for nearly 20% of production. Also, the company is the single largest pure-play Montney producer and sixth largest energy company in Canada. With a deal of this size, and the market share being so large, ARC’s development decisions could singlehandedly change the price of condensate in Canada or its differential to WTI. The deal also gives ARC flexibility on whether to drill liquids rich or dry acreage in response to the market. n Whitecap making waves:
Whitecap continues its M&A drive as it is set to acquire Kicking Horse Oil & Gas (a privately held subsidiary of Quantum EP). The deal has a total consideration of Cdn$300 million, the bulk of the deal is made up of 34.5 million Whitecap shares.

Biden-Harris Administration 3. The put forward its American Jobs plan which includes US$16 billion in natural resources clean up, enough to plug and abandon hundreds of thousands of old wells.
This is Whitecap’s 14th acquisition since 2010 and the associated production is expected to grow from 8,000 boe/d to over 18,00 boe/d by the end of this year. The Karr acreage fits well into Whitecap’s portfolio, with over 360 net locations, and expertise having previously purchased Karr assets in 2014. n Carbon constitutional – who is driving innovation?
The Supreme Court of Canada announced a ruling on the constitutional challenge of a federal carbon tax by Alberta, Saskatchewan and Ontario. Alberta and Ontario were concerned with the carbon tax on fuel which directly impacted consumers. Both provinces have existing heavy emitter policies, which remain in place regardless of the ruling. Saskatchewan stood alone against the GHGPPA in its entirety. In related news, carbon capture and storage (CCS) is being increasingly implemented in Western Canada. Most recently, Advantage Oil & Gas announced plans for a new Modular CCS installation at its Glacier gas plant; this is the first project of its kind. Following this investment, the company expects to be carbon net-zero on scope 1 and 2 emissions. After the Phase 1 build out for Cdn$27 million, Advantage expects to generate Cdn$3 million per year in operating income at Cdn$50/tonne CO2e. Phase 2 is expected to cost Cdn$49 million and sequester an additional 136 MTCO2e/year by as early as 2023. There is substantial potential income to be had with the federal carbon price growing to Cdn$170/tonne CO2e by 2030.
US ONSHORE: n Pioneer acquires DoublePoint energy for
US $6.4 billion:
Following the October 2020 Parsley acquisition, this deal is the next iteration of Pioneers Permian-focused strategy. DoublePoint was a "build to sell" private-equity-backed Permian pure-play operator with a largely overlapping 97,000-acre position in Upton and Midland counties; our models value this acreage at US $5.1B, 20% lower than the acquisition price. Pioneer estimates that it can drop DoublePoint’s rig count from five to seven and stabilize their production at 100mboe/d in 2021. The deal will add more scale to Pioneer’s portfolio and Pioneer’s lower cost of debt capital will make drilling wells on DoublePoint’s acreage more profitable. Our inventory model for DoublePoint indicates there is potential in the Spraberry (submarine fan complex) and Wolfcamp A, B and C intervals (mudrocks, carbonates and shales). n No country for old wells as the White House
prepares to spend billions on P&A:
On 31 March 2021 the White House unveiled the American Jobs Plan. Contained in the document was a plan to provide US $16B in funding for orphan well plugging and abandonment as well as hard rock, uranium and coal mine clean up. There were three goals stated: 1. Plug orphan wells and clean up old mines 2. Create jobs in rural communities 3. Reduce methane and produced water (brine) leaks from aging and improperly cared for wells In 2020 we laid out a comprehensive overview of P&A liabilities in the US. At the time we estimated there were nearly 2.4 million
vertical wells and 215,000 horizontal wells in the Lower 48 that at some point would all need to be plugged and abandoned at an estimated median cost of US $55,000 per well. It is important to note however that most of these wells have a solvent owner and are not orphaned. To give the P&A funding context, federal agencies were, on average, spending approximately US $285 million per year on orphan well P&A activities. We don’t yet know what the spit will be between P&A and mine clean up, but even a small portion of the US$16B in funding would go a long way. As an example, at an average cost of $55,000 to P&A an orphan well, if only a third of the proposed funding goes to P&A, it should provide enough funding to plug and abandon nearly 100,000 wells. The Canadian government put out a similar fund of C$1.72 Billion in May 2020 which focused on cleaning up orphan wells across British Columbia, Alberta and Saskatchewan. n Core Marcellus is still the best tight gas
play in town:
The Marcellus remains the bellwether of US tight gas. Productivity in the play has plateaued, yet it remains one of the most productive gas plays in the Lower 48. In the face of low natural gas prices and a falling rig count, Marcellus gas, perhaps paradoxically, continues to grow. This is mainly being driven by operators shifting to the higher productivity, but drier, gas zones in the SW Marcellus (Greene and Washington counties). While it may not seem like much, we find that an increase from $2.50/mcf to $3.00/mcf significantly improves payback periods and well economics for operators and supports wider activity. For the top four sub-plays, which together represent 3.6 million acres (14.6 thousand square km) and nearly 10,000 remaining locations, as gas prices trend toward $3.00/mcf HH these wells will breakeven within the first 15 months.
TOP FOUR MARCELLUS SUB-PLAYS, PAYBACK PERIOD AT VARIOUS NATURAL GAS PRICES (Flat WTI price of $48/bbl was used in this analysis)
OIL SANDS: n Records rolling into 2021
CNRL reported a mining production record in Q4, with strong production at Horizon and its Athabasca Oil Sands Project. Imperial’s Kearl also had a record quarter, producing above its nameplate capacity by 5%. It is important to note that we have not seen any material impacts from earlier 2020 decisions to shut in production.

CURTAILMENT ENDED IN ALBERTA Q4 2020 marked the final moments of the mandated curtailment in Alberta. Operators began to ramp up production with clarity on the end of curtailment coupled with improved prices and narrow differentials in 2021.
EMISSIONS: With a focus on emissions management and sustainable development rather than pure growth portfolios, more operators are picking and choosing the projects they are investing in. One recent example is Murphy Oil, who has shifted significant capital to development of its Tupper Montney. This is driven both by economics, with AECO prices at its lowest differential to Henry Hub in years coupled with an average emissions intensity below 5 tonnes CO2e/ kboe; the lowest in its portfolio. n Tight oil emissions: High returns on
a low carbon diet?
A new insight from Wood Mackenzie benchmarks projects on emissions and economic returns. The Marcellus and Permian not only exceed investment hurdles but also support Scope 1 emissions intensity goals. For companies with global portfolios, top-tier shale projects can provide a balance of scale, strong returns, and relatively low emissions. n

2020 CSPG Award Recipients
2020 MEDAL OF MERIT AWARD The Medal of Merit has been awarded since 1952 and is the most prestigious and oldest technical award of the society. The medal is awarded annually for the best peer reviewed paper on a geological subject related to the petroleum geology or the geology of energy generation and extraction, of Canada. The stated objectives of the Medal of Merit Award are to promote the preparation and publication of geological papers of high quality, to give honorable recognition to works of merit, and by means of suitable publicity, to bring the attention of the members and of the public to the activities of the geological petroleum profession by awarding the Medal of Merit annually for the best paper. The Medal of Merit is awarded to a paper published during the previous publication year, in this case for peer reviewed papers published in 2019.
The paper awarded the Medal of Merit for 2020 was written by L. Moscardelli, J. Ochoa, I. Lunt and L. Zahm and is entitled “Mixed siliciclastic-carbonate systems and their impact for the development of deep-water turbidites in continental margins: A case study from the Late Jurassic to Early Cretaceous Shelburne subbasin in offshore Nova Scotia.” The paper was published in the AAPG Bulletin, Vol 103, No. 10, p. 2487-2520 (October 2019). The paper reviews the deposits and plausible depositional processes of the Late Jurassic to Early Cretaceous of the Shelburne sub-basin using well, drill core and seismic data. Early Cretaceous deltaic sandstones have been penetrated on the shelf, along with carbonate deposits such as ooid shoals and the offshore sub-basin is interpreted to be prospective for deep-water sandstones as deltaic, but thick deep-water sandstones have not been documented. The authors integrate observations from the generally under-studied margin and propose two models for the lack of deep-water sandstone in the mixed siliciclastic-carbonate system. The first model proposes sand was trapped on the margin because carbonate deposits on the shelf trap sediment and prevented transport down the slope. The second model proposes that the carbonate deposits were locally breached and deep-water sands were deposited in specific, but yet-to be penetrated areas. The authors favour the second model as they interpret localized sediment sources and slope-bypass from core and seismic observations and identify areas of possible deep-water sand accumulation. This work is an important contribution to Canadian petroleum geology literature as it provides a comprehensive investigation of a Canadian margin with complex geology, ingredients of a working petroleum system, but thus far, limited success. The work is also more broadly applicable as few studies attempt to link shelf and basin processes and deposits when dealing with carbonate-siliciclastics systems.

The Psychology of Geology:
Unearthing Creativity Amongst the Uncertainty By Kiersten Mohr B.Sc., B.A.
A
fter fifteen years as a geologist and technical leader in the energy industry, I decided to go back to school to pursue a psychology degree. Initially, I intended to increase my capacity and competency in the nonprofit world in which I had begun to invest a lot of volunteer time. However, it did not take many classes to quickly realize the applicability of this knowledge to my geoscience and leadership career. The more I learned about what I had previously envisioned to be a completely unrelated discipline, the more I wanted to know, which is one of the things that has led to me continue with a Master's Degree in Counselling Psychology. When I network in the energy industry, I often refrain from mentioning my focus in this new field. I feel concerned that sharing insights from my new discipline may reflect poorly on my dedication and passion for geoscience. When I do share, I am often met with a look of confusion followed quickly by curiosity as to why I didn't pursue more education in geoscience instead. In one case, in a job interview for a leadership role, I was asked why I didn't pursue an MBA or something more 'relevant' to the energy industry. Every time these experiences happen, it reinforces how as an industry, we often undervalue knowledge and skills that can be used to support our biggest assets – our people.

Geoscience and Creativity One of the aspects I love the most about geoscience is the space it provides for creativity, imagination and innovation. In an industry full of budgets, strategic plans, reserve calculations and performance reviews, being a geoscientist offers a window into an exciting world that requires embracing uncertainty and thinking outside of the bounds of what we may already know. It is a chance to get out of Excel and PowerPoint and into 3D subsurface models and boxes of core and well logs to collaborate, letting new ideas collide and ultimately unearthing innovative interpretations and theories. I love that geoscientists get to be storytellers, and through history, our collective contribution has been where many discoveries and new opportunities have been born. I trust that nearly all of us would agree that creativity is essential to be a successful geoscientist. As a technical leader, encouraging and fueling creativity and developing skills to help increase innovation potential was one of the first connections I saw within the psychology principles I have been learning. While our technical intelligence as geoscientists is important, I now appreciate that it is also important to support professionals to increase their emotional energy and ability to focus, to encourage positive interpersonal relationships, to create space for safe and meaningful collaboration, and to always provide a genuine sense of safety and security for individuals to explore outside of the boundaries of a challenge. In essence, to encourage and promote a highly effective, innovative and creative geoscience team, we need to focus on the people.
The Challenge In many ways, our industry and geoscience discipline are experiencing one of our most challenging times in history. As the focus has shifted from exploration to exploitation, there is a seemingly daily challenge to the validity and necessity of the science we all love. As the industry struggles with low commodity prices and a lack of consistency or confidence for the future, many geoscience professionals are living with daily career uncertainty. Compounding these already overwhelming challenges, we have been faced with a global pandemic that has added familial and social pressures and ultimately robbed many professionals of the time, space and emotional energy to be creative. It is a perfect storm. At a time in our industry when it has potentially never been more crucial to be creative and innovative to enhance recoveries and reduce costs, we are also facing the most immense barriers inhibiting our ability to be truly creative and innovative.
Finding Creativity in the Uncertainty Embrace and Communicate Uncertainty For most geologists, dealing with uncertainty is not a new thing. Our careers require us to continually weigh technical risks and navigate landscapes and decisions full of subsurface uncertainty. We have learned to creatively manage this uncertainty by
soliciting alternative viewpoints, communicate our technical work, and brainstorm alternative outcomes with colleagues. It is in this process of externalizing our understanding of the risks and uncertainty, that we become more comfortable recommending the high-cost projects we do.
In the ever-changing landscape of both our discipline and industry, encouraging and recognizing grit has never been more critical.
In psychology, grit is defined as an individual's endurance, perseverance, passion and most importantly, the persistence to overcome obstacles on the path to However, when we move to the 'surface' (our personal achieving a goal. In essence, and career challenges), it is easy to fall into creative grit is not about what we paralysis, inadvertently allowing our cognitive capacity to be achieve but instead how consumed with 'fortune telling' all the things that may or Different doesn’t mean bad – we achieve it. The value of may not happen. Given the industry's seemingly constant focusing on and recognizing it just means different. pessimistic news, this is a chronic challenge for all of us. grit is that it helps blur the While I don't propose any magical fix, I believe we can use lines between work and life and a similar approach by leveraging peers, mentors and friends encourages us to recognize, to vocalize and discuss our predicted future outcomes. be more aware of, and identify Just as in the challenge of subsurface uncertainty, the act of the external factors that an externalizing these concerns will make them more tangible and individual needed to overcome in order to accomplish increase our ability to think genuinely about the probability of their outcome. a goal. Ultimately, this focus on seeing someone as Additionally, this conversation helps introduce alternative viewpoints, concretize a person versus a geoscientist can increase an more adaptive and positive thought processes, and increase overall sense of individual's feelings of accomplishment, acceptance, control. Just as in the subsurface, this exercise may not remove uncertainty, security, mitigate uncertainty fatigue, and increase but an increased sense of control will often lessen the distress and cognitive creative and innovative thought capacity. In the load and open up more space for creativity. ever-changing landscape of both our discipline and From a leadership perspective, one of the biggest frustrations I experienced industry, encouraging and recognizing grit has never was finding myself in discussions with senior leaders talking about how to been more critical.

Calgary Zoo Flood Mitigation: Groundwater Management and Dewatering on an Island Speaker: Soren Poschmann, ISL Engineering’s Water and Environment group May 4th, 2021 | 12:00-1:00pm MST E-Technical Division Talk
A B S T R AC T
As high ground and berms already existed on parts of St. George’s Island, initial flood mitigation concepts focused on protecting the island from overland flooding. Flood protection berms and walls were conceived as suitable options to withstand the flooding effects while preserving as much functional space as possible for Zoo operations. The potential for flooding from groundwater sources required further study, however. As the flood mitigation design evolved, investigations and flood simulations confirmed the direct hydraulic connection between the Bow River and the groundwater in the underlying gravels — as river levels rose, so did groundwater levels. Consequently, proposed solutions would need to protect against both increases in groundwater elevation and overland flow. The most effective solution to protect St. George’s Island against flooding was to seal the island interior from overland flow and groundwater ingress. Enclosing the island’s perimeter required installation of a barrier capable of penetrating the highly permeable fluvial cobbles and boulders that make up most of the island and riverbed, while ensuring a reasonably watertight seal in the impermeable bedrock below. Recognizing that the barrier would not be completely watertight, a hydrogeological model informed the design of a dewatering system that had sufficient capacity to control groundwater levels expected from the 1:100 year flood event. The natural groundwater level within the contained area would be lowered each spring and summer to buffer against leakage and rainfall, such that the river flood pulse could pass without increasing groundwater elevations to critical levels. The dewatering system consists of ten pumps distributed throughout the island connected to outfalls that discharge to the Bow River. Although designed with a total pumping capacity of 165 L/s to handle the modelled groundwater inflows expected during the design flood, the system was also designed to be easily expandable to include larger or more pumps, if required.

he Calgary Zoo, located primarily on St. George’s Island at the confluence of the Bow and Elbow rivers, experienced flooding along with much of Southern Alberta in June 2013. The Calgary Zoo was inundated and without power in the early morning hours of June 21, having had less than 10 hours’ notice to enact their flood operations plan. In that time, the Zoo evacuated as many animals as possible from the collection of more than 200 animals on the island. As initial recovery of the Zoo commenced, ISL Engineering and Land Services Ltd. was retained by The City of Calgary to study options on how to protect the Zoo from future flood events. Associated Engineering was engaged as a key partner following the planning stage.

n January 7, 2021, the Structural Division presented a very popular talk on natural fractures in the Duvernay Formation. Some of the discussion involved assessment as to whether the presence of fractures in the reservoir is a good thing or a bad thing. This talk is sort-of a follow-up to that and will discuss the mechanical stability of natural fractures in general, including the potential implications (good or bad!) for a number of issues such oil and gas well completions and production, geothermal development, subsurface fluid storage and more. It will also make the case that we should probably be paying closer attention to fractures in our reservoirs!

iostratigraphy is a fundamental oilfield service which is based on the analysis of microscopic fossils. Demand for this service is global; for example, it is a standard requirement on almost all offshore exploration wells. However, the use of oilfield paleontology has waned in Canada, largely due to a lack of investment, retirement of specialists, and lowered interest in industrial and academic research institutes. Oilfield paleontology commonly involves three paleontological disciplines, each conducted by a relevant specialist: 1) Micropaleontology [foraminifera, ostracods, radiolaria, diatoms, conodonts, etc.]; 2) Nannopaleontology [calcareous nannofossils]; and 3) Palynology [spores, pollen, dinoflagellate cysts, acritarchs, and other organic walled fossils]. Each discipline has unique advantages and challenges, and it is important to select the best and most effective discipline(s) for any given geological scenario. The frequency of cuttings samples, availability of core or sidewall cores, and even the drilling technique applied can all have a bearing on acquisition of biostratigraphic data. Sample processing needs to be tailored to particular fossil groups. The processing and identification of fossils can be done on the rig in real-time, or later in the office. Current standard applications include dating of the sediments, correlation with surrounding wells using biostratigraphy, and the modeling of depositional environments. On rig interpretation (especially for costly offshore wells) is commonly used to assist with key stratigraphic picks for casing, coring and TD determinations, all of which may be safety critical, and “biosteering” horizontal wells. Biostratigraphic data can also be integrated with sequence stratigraphic models, supporting basin analysis and the confident correlation of seismic horizons. Palynology has some other key applications including source rock analysis, thermal maturation (along with conodonts), non-marine stratigraphy, palynofacies construction, and paleoclimate resolution. The fossils used are so small that it is often possible to find hundreds (or even thousands) of specimens in one sample, and statistical analysis of quantitative datasets assists model generation and paleoenvironmental interpretations. As outlined above, paleontology has many value-adds to exploration and production geoscientists. Recent developments include the application of automatic fossil identification using Artificial Intelligence, machine colour recognition for thermal maturation, and integration with isotopic/elemental stratigraphy studies. Future directions in palynology could include genome analysis and bacterial spore stratigraphy. The study of organic and inorganic microfossils will continue to be a great value add to petroleum exploration and production. This presentation aims to highlight some of the applications of this fundamental but sometimes forgotten science.

Using the oil sand and shale resource plays in Western Canada as a proving ground, Explor has overcome significant technical and environmental challenges to achieve a step-change in seismic data densities to better image resources underlying complex and sensitive forest ecosystems while simultaneously reducing the environmental footprint of those operations. To achieve these outcomes, Explor has developed and patented a new high-resolution, low-impact, single- person-portable, impulsive seismic source system that can deliver high quality seismic images without the need for opening source lines.
Recently, Explor has also tested the deployment of a new generation of lightweight seismic receiver nodes that together with lightweight source technology can significantly increase the efficiency of operations making high density near-zero footprint seismic acquisition commercially viable. This technology will have broad applicability to environmentally sensitive onshore regions around the globe, transforming the process for seismic acquisition in resource-rich sensitive ecosystems in sub-Saharan Africa, Colombia, Brazil, Peru, Bolivia, and Papua New Guinea to name just a few. Tests are also being planned in support of Carbon Capture and Sequestration projects in the Continental United States. We will share our seismic journey, the results to date, and our plans for driving to zero footprint ultra-high density seismic data.

ertebrate paleontology in Saskatchewan today is inextricably linked to charismatic dinosaurs like Triceratops and T. rex (the provincial fossil emblem), and to the province’s impressive array of endemic marine reptiles. However, it was not Mesozoic mania that first drew paleontologists to the province in the Twentieth century. It was the Cenozoic mammals. The oldest diverse fossil mammal assemblages in Saskatchewan are found in the Late Cretaceous; the small - and sometimes not-so-small - furry critters that shared their landscape with T. rex and Triceratops. The province is also well known for its early Paleocene mammals, sometimes found just centimeters above the K-Pg Boundary. Many of these survivors of the dinosaur mass extinction gave rise to linages from which modern North American mammal faunas stem. These taxa are known primarily from tiny teeth and/or jaws, as mammal teeth preserve better and are easier to identify than post-crania. It is generally not until the Eocene that some mammals and their fossil remains get big, heralding in the age of Cenozoic giants. Some of the earliest discoveries of vertebrate fossils in western Canada were of Paleogene (Paleocene - Miocene) mammals in the Cypress Hills region of western Saskatchewan, from what is now known as the Cypress Hills Formation (CHF). The first record of a CHF fossil assemblage was made by R. G. McConnell in 1883, less than a decade after George M. Dawson reported Canada’s first dinosaur fossils in Saskatchewan. It is now recognized that the CHF contains fossils from a time period not represented anywhere else in Canada, but which are a northern extension of fossil mammal-bearing units in the Great Plains of America. Since the discovery of dense microvertebrate mammal sites in the CHF, collections of from this formation have grown almost exponentially. In Canada, hundreds of thousands of fossils from the CHF are housed at the Royal Saskatchewan Museum (Regina and Eastend, SK), Royal Ontario Museum (Toronto, ON), Canadian Museum of Nature (Ottawa, ON), and other institutions across the country. The formation is now known to contain a mix of extant mammal groups including artiodactyls (even-toed ungulates), rodents, marsupials, lagomorphs (rabbits and their allies), early primates, camelids and early candids. It also contains an array of now extinct groups like multituberculates, mesonychids and the bizarre condylarths.

Arguably, the CHF taxa that have generated the most public attention are the perissodactyls, or odd-toed ungulates. These included rhinos, the small leaf-eating early horses Hyracotherium (Eohippus) and Mesohippus, and the elephant-sized brontothere (Latin for ‘thunder beast’) Megacerops. In addition to the mammals, fossils of other vertebrates including snakes, lizards, turtles, crocodiles, birds, amphibians (including a metre-long hellbender salamander) and a diversity of fish are also well represented in the CHF. Despite the vast collections fossils from the formation, the CHF was for decades thought to be comprised of a single biostratigraphic unit from the early Oligocene. We now know that the formation spans a time period from the midEocene, though the Oligocene, and into the earliest Miocene. The formation encompasses a major floral and faunal turnover event across the EoceneOligocene (E-OG) boundary, which is suggested to be related to climate cooling. As the climate cooled, the forests began to disappear and were replaced by grasslands. It was during the E-OG event that many browsing mammals (e.g. brontotheres) went extinct and grazing mammals (e.g. horses) became more prevalent. No other geological formation in Canada, and few others in North America, offer such a unique opportunity to study this continuous sequence of evolutionary and ecological transitions.
This event is presented jointly by the Alberta Palaeontological Society, the Department of Earth and Environmental Sciences at Mount Royal University, and the Palaeontology Division of the Canadian Society of Petroleum Geologists.

he year of the pandemic will be remembered as a time of deep disruption. We have all been impacted and many of us were faced with a stormy superimposition of crises that in my case included an international assignment while having the responsibility of taking care of aging parents and a sudden death in the family. The cherry on top? The real risk of losing both job and career to the ongoing industry crisis. This is about sharing the view that little victories act as life’s compounded interest, that a support network is key to survive and my conviction that hope is the only thing that we can’t afford to lose during times of deep distress.
A fun AAPG interview with Lorena can be found here:

lecting to return to school at any age is never an easy career choice. It means forging ahead into the unknown, learning new skills, pushing oneself outside of their comfort zones, knowledge sharing across the generations, and utilizing known skills obtained over one’s professional career to leverage learning to a whole new level. Sustainability may be THE word of the 2020s, sustainable energy, sustainable finance, sustainable toothbrushes – but what does it all mean, and how can we all be a part of the most significant economic opportunity of the century. Join me for a conservation about my journey as a geologist, how I came to be involved in sustainability, and what sustainability means to me. I will also discuss my capstone research projects focus on ESG (environmental, social, governance), what educational programs are available for sustainability, and what the future may hold for energy scientists going forward.

Black Gold: the World’s Oldest… and Richest… Oilfield? Jon Noad, Sedimental Services; University of Adelaide
“See the world in just one grain of sand…” KARL WALLINGER, 1990
It is easy to think of hydrocarbon deposits as forming only in Phanerozoic times (less than 540 million years ago), or possibly dating back into the late Precambrian. However, there are some extraordinary, oil bearing rocks dating back well into the Archean (2.5 to 4 Billion years old), of which those in the Witwatersrand Basin of South Africa host the world's greatest gold reserves. This is no coincidence, as the bituminous carbon reserves clearly enhance gold concentrations, as explained below.
Geology of the Witwatersrand basin (Frimmel 2019). Note the location of the Welkom gold field (#9) in which St. Helena Gold Mine is located.
1. The Witwatersrand Basin The Witwatersrand Basin (“Wits”) is located in South Africa and hosts the world's largest known gold reserves. It has produced over 1.5 billion ounces (40,000 metric tons) of gold, which represents about 22% of all gold ever mined. The basin fill consists of a c. 6000 metres thick Archean package of mainly sedimentary rocks dating to around 3 billion years in age. The entire series of rocks is known as the Witwatersrand Supergroup and includes quartzites, banded ironstones, mudstones, tillites, conglomerates and lavas. Some of these rocks outcrop around Johannesburg, dipping downward into the subsurface to form the Witwatersrand Basin, an elliptical structure some 300 kilometres in length and 150 kilometres in width. The gold bearing rocks appear to be constrained to six areas (outlined in blue on the map below) where Archean rivers from the north and west formed fan deltas, with many braided channels, before flowing into the “Witwatersrand Sea” to the south. Gold is found in selected conglomerate strata of the younger members of the Supergroup and tends to occur in streaks with larger pebbles. It is associated with iron pyrite (so called “buckshot pyrite”) and uraninite, as well as carbon rich materials such as kerogen, or bitumen, which occur as small balls, 1 to 4 mm in diameter (flyspeck carbon), or in layers up to 2 cm thick. The gold is thought to have been sourced from eroded greenstone belts to the north and west of the Basin.

The initial fill of the Witwatersrand Basin was marine (West Rand Group, beginning 2970 MYA), overlying basement granites, with glacial episodes. Uplift of the northern Kaapvaal Craton led to a regression and the deposition of braided deltas (Central Rand Group). The rivers deposited large pebbles and heavy minerals and, in the absence of free oxygen, cyanobacteria flourished in these waters. The deposition and periodic erosion of sediments, during a series of eustatic cycles, was ended by the massive outpourings of Ventersdorp lavas around 2715 MYA. A later meteor impact, forming the Vredefort Dome, contorted and hence helped to preserve the basinal sediments.

2. Description of sedimentary deposits Typically, the gold bearing “reef” deposits are less than a metre in thickness. They are dominated by conglomerates with a crossbedded quartzite matrix, with associated pyrite, uranium and gold (see below). There are basal scours into the underlying Middling Quartzite, as well as bar forms composed of quartzite, within the overall conglomeratic deposits. These bedforms exhibit trough cross-bedding overlain by current rippled quartzite. The cross-beds are often picked out by detrital pyrite. The “reef” deposits range from strongly erosional deposits that pinch out laterally, interpreted as channels, to laterally extensive, sheet-like deposits. The sheet-like quartzites are also coarsely trough crossbedded with rare wave ripples. The quartzite matrix was originally a sandstone that was later metamorphosed.

The erosional facies, with limited lateral extent, is interpreted as low sinuosity to braided channels. The channels range in width from less than 100 metres to more than a kilometre, but rarely exceed 2 metres in depth. The interpretation of these deposits as braided river deposits is supported by the pay trends, which frequently map out the individual braid bars (see map in section 5). The sheet-like deposits are of a similar thickness and may indicate a (more extensive) shallow marine depositional setting. Other facies include thick quartzites almost devoid of clasts. The succession exposed by mining at St. Helena Gold Mine exhibits a wide variety of facies over a 25 metre stratigraphic section (see below), and has been interpreted using modern sedimentological techniques, utilizing sequence stratigraphy:

3. Associated heavy minerals The gold occurs in around a dozen palaeo-placer deposits. It is typically disseminated within the conglomerates except when preserved with carbon, where it occurs as seams or vertical stringers. Around 40% of the gold is found with carbon. The reduced carbon is present as kerogen, and SEM data indicates that it was probably originally a microbial mat. These mats may be preserved as the carbon seams and stringers. Buckshot pyrite may reach a centimetre or more in size, and pick out cross-beds and rippling, indicating that they are a primary deposit. The absence of oxygen in the atmosphere, coupled with common volcanic eruptions, preferentially led to the formation and preservation of large amounts of pyrite. Uraninite occurs as rounded grains and also appears to be a primary deposit, indicating the anoxic nature of the depositional environment.

4. Carbon: a model for gold enrichment in the Wits The carbon in the Witwatersrand sediments is interpreted as a metamorphosed hydrocarbon deposit. Carbon isotope ratios support an (cyanobacterial) algal origin, possibly present as microbial mats flourishing in the mineral rich waters of the braided rivers. The original plant material was then converted to a kerogen and later a hydrocarbon, probably bitumen, before migrating and infilling pore spaces within the conglomerate. The bitumen was metamorphosed over time to pure carbon. The carbon is associated with high gold values. A theory from the 1970s suggests that the gold was transported as a soluble gold bisulphide complex in Wits rivers, and later precipitated on contact with the algal mats. This process was facilitated by the presence of oxygen emitted by photosynthesizing algae. It is also possible that the gold, present as ions in mineral rich pore waters, formed
40 R E S E R V O I R I S S U E 3 • M A Y / J U N E 2 0 2 1
an amalgam with the carbon after it had been metamorphosed from algal material, gradually enriching the seams and flyspeck carbon with gold. There is strong evidence that some of the carbon was remobilized as a hydrocarbon after deposition, filling early fractures. The amount of carbon present within the conglomerate relates to the amount of primary plant material present in the deposit, the efficiency of the maturation process, the connectedness of the migration pathways and overall porosity. At least in part, the gold concentrations will reflect, and act as a proxy for, primary porosity within the matrix. It is likely that there was secondary enrichment of the gold from mineral rich pore waters, with the later gold forming an amalgam with the carbon.
5. Case Study from St. Helena Gold Mine A data set was collected from the Leader Reef Zone (LRZ) of the Witwatersrand Supergroup, exposed close to one kilometre underground at St. Helena Gold Mine in Welkom. A total of 156 sections ranging from 1-4 metres in thickness were logged in an area of around 150 x 150 metres, covering a bend in an individual channel (Noad 2001). The channel is estimated to have a width of around 200 metres. In addition, samples were taken for gold assay at around 7-10 cm intervals vertically for each logged section. It was possible to subdivide the LRZ into three intervals: a lower channelized, conglomeratic zone (Alma Unit); a middle sheet-like, quartzitic interval with fewer clasts (Bedelia Unit); and an upper, barren quartzite with tiny, angular, multicoloured mudstone clasts (Leader Quartzite). The facies were subdivided into A. pebble conglomerates (with a mix of well rounded quartz and chert pebbles) with buckshot pyrite and flyspeck carbon, B. pebbly quartzites and C. dirty quartzites. Trough and low angle cross-bedding was occasionally picked out by pyrite or opaque material in the different lithofacies. The deposits were interpreted as braided river deposits overlain by a transgressive marine sheet-like body (see the logged section and interpretation in section 2).

Image from the model showing the variation in thickness across the study area. Gold values ranging from 0-125 grams/tonne were recorded from these rocks. The gold concentrations relate to carbon concentrations, which are interpreted as metamorphosed plant material and potentially bituminous hydrocarbons. Higher gold values are thought to indicate more algal material (see section 4) and act (indirectly) as a proxy for higher porosities. A 3-D model of the dataset was constructed to investigate the gold distributions, and kriging of the gold values allowed the interpolation of a 3-dimensional “pseudo” porosity cube through the channel and overlying sheet.

Cross-section through the 3-D model showing the distribution of gold values through the ore body, with the highest values in red and yellow, and the lowest in purple and blue. The table shows how gold values (grams/tonne) have been (imaginatively) correlated to primary porosity.
Summary The results of the modelling demonstrate that the gold values were concentrated along the basal channel contact, and at the base and top of the sheet-like interval. The values were lowest in the upper part of the channelised succession. These results can therefore be used to provide a template for porosity distribution in channel systems and suggest that horizontal wells should be located in the upper portion of individual, oil or gas bearing channel deposits, in order to maximise sweep efficiency, thereby reducing the risk of early water breakthrough due to high perm streaks. The highest gold values occur in association with the highest carbon concentrations. Gold values up to 10 kg/tonne were recorded in the thicker carbon seams in the Basal Reef, a quite extraordinary figure. Extrapolating from this value gives 3970 grams of gold per barrel, which at today’s prices equates to around $277,940 CAD. Surely this must be the world’s most economic hydrocarbon deposit. n
