A Model Approach of Controlling Coning in Oil Rim Reservoirs
Abstract: Water and gas coning in oil rim reservoirs poses serious hindrance to optimizing oil production in the thin oil beds as unwanted fluids tend to replace oil in the production stream. This invariably limits the ultimate oil recovery. In this study, semi-analytical models of estimating critical rate and optimum horizontal well placement were developed to control coning tendencies in oil rim reservoirs. The models were developed through semi-analytical analysis of …
