Gulf Coast Oil Fields Characterized Using XX Expert System--A Test Case for PLAYMAKER

PLAYMAKER describes oil fields of the Gulf Coast using basin and structural history, reservoir quality, source, seal potential, their location, sediment type, geometry, and facies models. PLAYMAKER subdivides the fields of the Gulf Coast into six groups: (1) the Upper Jurassic Smackover group (production from grain carbonates and diagenetic porosity; sourced from downdip offshore marine carbonates, marls, and shales and sealed by updip evaporites), (2) the Lower Cretaceous Sligo, Trinity, and Edwards Formations (production from shallow-shelf bioclastics, oolitic grainstones, and some rudistid build-ups; sourced from downdip offshore marine shales and marls and sealed by either updip shales, dense limestones, or evaporites), (3) the Upper Cretaceous Woodbine and Taylor Gro ps (production from shallow marine coastal complex sandstones; sourced from downdip offshore shales and sealed by updip shales), (4) the Paleocene and lower Eocene Wilcox Group (production from deep-water sandstones; sourced from downdip Wilcox shales and sealed by updip shales), (5) the Oligocene Frio, Anahuac, and Vicksburg sandstone groups (production from shallow marine coastal sandstones and some deep-water sandstones; sourced from Anahuac shale with migration up listric faults and sealed by updip shales), and (6) the upper Miocene, Pliocene, and Pleistocene Fleming and often unnamed sandstone groups (production from shallow marine coastal complex and deep-water sands; sourced from downdip shales and sealed by updip shales). Field characteristics are stored in the XX field matrix so geologically similar fields, plays, and prospects can be compared.
