Factors affecting mechanical water shutoff

As most of the oil fields operated by Gulf of Suez Petroleum Co. (Gupco) ma ture, water production increases, presenting: severe problems from both tec hnical and cost bases. Overloading the surface facilities, increased gas-li ft requirements, corrosion, and production-string damage are some of the pr oblems. Handling produced water is even more crucial with ecological and en vironmental interests and requirements. This study investigated an 8-year h istory of rigless water shutoff (WSO) jobs in various reservoirs operated b y Gupco. Analysis of the available data helped establish an optimized plan for setting mechanical bridge plugs (MBP's).
