Production strategies for maximizing recovery from a strong bottom water drive reservoir

This paper examines the effect of production rates on the ultimate gas recovery from a high permeable strong bottom water drive reservoir. A real gas field simulation model was history matched applying manual history matching techniques .Well behavior and recovery were observed for different prediction scenarios. It was found that cumulative recovery with additional wells would be higher during the initial years but ultimate recovery will be lowest because of a faster rate of water table movement. Maximum ultimate recovery can be achieved by continuing the production with timely and sequential workover of high water cut wells to plug back the lower perforations. High permeability and rapid movement of water table have made the reservoir highly rate sensitive and lower production rate may result in higher ultimate recovery.
