Downhole Water Sink (DWS) completion prevent water coning problem by concurrently producing water from bottom completion below the water oil contact, and oil from another completion at the oil zone. This method of completion might results in uneconomical oil production rate due to low reservoir pressure and/or low productivity index (PI). To overcome this issue, this paper introduces dual electric submersible pump (DESP) as artificial method in DWS completion well. ESPs boost the pressure of the produced fluid, allowing an increase in the well drawdown and providing the additional energy required by both oil and water to flow to the surface. This paper presents a feasibility study and design procedures for Dual ESP application in DWS well. Two DESP configurations were explored, concentric tubing configuration and downhole commingled configuration. The results of the design are the combination of ESP and ByPass tubing, by considering the number of stages, total efficiency, and required power for both pumps. Using data from actual field, a comparison study was conducted. The results indicate that Dual ESP would increase the oil production rate from 79.4 BOPD in conventional DWS well to 600 BOPD with total efficiency <br /> <br /> of 26.64% for concentric tubing configuration and 755.5 BOPD for commingled configuration. This paper also presents bypass tubing selection matrix for several casing size.
