Optimization of Well Rates Under Gas Coning Conditions

Abstract

This paper develops a method for optimizing well rates when wells are coning gas and field rates are constrained. Since each well's GOR depends on its rate, then well rates must be individually specified. This method maximizes field oil rate when gas rate is fixed and minimizes field gas rate when oil rate is fixed. The method can be used for (1) field operation, (2) reservoir simulation forecasting, or (3) simple material balance applications (as shown in the paper).
