GULF-OF-MEXICO HORIZONTAL WELL IMPROVES ATTIC-OIL RECOVERY IN ACTIVE WATERDRIVE RESERVOIR

This paper presents a Gulf of Mexico field case study describing the u se of horizontal wells to improve oil recovery in thin attic-oil, stro ng waterdrive reservoirs. Prewell planning shows the use of reservoir simulation for well performance forecasts, discusses selection of dril ling mud for minimal damage, logging while drilling (LWD) for steering and optimal completion techniques. Post-well results show that horizo ntal wells, applied with an integration of technology, not only help a ccelerate production but also improve oil recovery compared with conve ntional wells for this type of reservoir problem.
