Abstract

The drilling strategy of North Kuwait has embraced in the last few years to get more reservoir contact to maximize oil recovery. Presently, the wells are drilled with high deviation angle to intersect multiple pay zones and drain the existing prospects. However, water coning and edge water breakthrough are challenging to achieve production longevity. Inflow Control Devices (ICD) is a proved tool in oil industry, which can delay the water encroachment by creating uniform drawdown across wellbore section. The production performance of ICD wells indicated stability of water cut for longer period as designed.

Answer products is the key to monitor downhole production profile to ensure the functionality of ICD units. Some reservoirs are suffering from pressure depletion and artificial lift (ESP) was installed to deepest point to increase pump efficiency. This type of completions is limiting accessibility to collect downhole data for further action.

Besides, after period if the water shutoff is required, the well intervention inside ICD completion is challenging due to bore size limitation and materials availability.

Proactive action was taken to utilize the advanced technology of ICD Completion, which allows faster execution of Rigless shutoff and reduce Rigs demands.
