Water coning is one of the production problems that causes oil recovery to be not maximum. Water coning is the phenomenon of water cone shape which moves upward to the perforation. Strong bottom water drive reservoir will trigger water coning to occur. Bypass oil is one of the water coning impact and causes oil recovery in the reservoir is not maximal. Several methods have been developed to overcome or at least reduce the effect of water coning problem. Downhole Water Sink (DWS) is one of developing methods to increase oil recovery by reducing effect of water coning. The principal of this method is to perforate both the oil zone and the water zone. Perforation in water zone creates a “pressure sink” and counters the development of the water cone towards the oil zone perforation. There are several conditions that can occur during DWS completion production, such as segregated flow, reverse coning, water coning and unstable contact. This paper goal is to optimize DWS using genetic algorithm for deltaic deposition field. Optimization process can be done by using genetic algorithm basis software that resulting optimum rate for top completion and bottom completion. Optimization plans is conducted to find out the best rate combination that gives the highest oil recovery.
