Abstract
A technique enhances hydrocarbon fluid production. The technique utilizes a well with a plurality of lateral wellbores positioned to facilitate removal of well fluid from a hydrocarbon reservoir. A separator is disposed in the well to receive well fluid that flows from a lateral production leg. Operation of the separator separates well fluid into an oil component and a water component to enable production of the oil component. The water component is injected into the reservoir in a manner that drives well fluid trapped in the reservoir into the lateral production leg.
