ell completion design with inflow control devices (ICDs) is one of the important steps in efficient field development planning. It has a strong influence on not only the production profile but also the economics. Technology advances, in conjunction with drilling capabilities, have significantly improved well productivity and enhanced hydrocarbon recovery. Reservoirs developed with horizontal wells face various challenges, such as early water and gas breakthrough, leading to reduced oil recovery. This is often the result of a variation in the reservoir properties, including the fluid and petrophysical properties, layer pressure and fluid contacts. Several studies assert that such challenges can be mitigated by deploying advanced well completions

to manage the reservoir fluid influx along the wellbore and therefore optimise the performance of wells.1 – 6 In addition, research suggests the application of autonomous inflow control devices (AICDs) to control water or gas production acts as a type of insurance policy against geological and dynamic reservoir uncertainties to reduce the risk and variation in the expected oil production profiles.7 In 2018, Tendeka successfully performed an infill development campaign for PETRONAS-Malaysia to improve production with the first delivery of its FloSure AICD completion in a complex offshore oil reservoir in Sarawak, northwest of Borneo.8 The field itself had been producing for more than 45 years (Figure 1).
