Optimizing commingle production strategy using integrated production model

Abstract

The hydrocarbon resources we have at subsurface are limited and hence top priority has always been to get maximum out of it. Many times perforation strategy has been done based on experience, and we have never had a chance to check if other perforation strategies will be able to deliver a better result. Simulation has made it possible to evaluate different perforation strategies in order to achieve the highest ultimate hydrocarbon recovery. In this study, reservoir models were built based on history matching on the production profiles using integrated production model. Then, six perforation strategies are applied to the same well in order to see the difference. The strategy delivering the highest oil recovery for most wells will be considered top performer for the environment in which the research is based on. The results obtained indicate that no single strategy appears to consistently deliver the highest ultimate oil recovery. For the recovery of water and gas, the actual perforation that include plug and patches yields the lowest water recovery and the bottoms up perforation yields the highest gas recovery. Regarding BOE recovery, bottom up perforation is the most favorable
