HOUSTON, Jan. 4 -- Pennsylvanian Booch sandstones that have produced oil and gas since just before Oklahoma statehood in 1907 have yielded 78 million bbl of oil and 467 bcf of gas through April 2004 from 2,690 active and abandoned wells, the Oklahoma Geological Survey said.
Most Booch production is from the Arkoma basin and Cherokee platform, with gas limited to the Arkoma. An OGS publication compiled by Dan T. Boyd and Rick Andrews, said 710 Booch gas wells still contribute 23 MMcfd. The 91-page review contains field studies of Brooken, Southeast Reams, and South Pine Hollow fields.
Operators have produced 107 bcf of the 110 bcf estimated ultimate recovery at Brooken on the shores of Lake Eufaula.
Sandstone in most of Brooken field is "of such high quality that net and gross thicknesses using an 8% porosity cutoff are essentially the same," Boyd wrote. No Booch accumulation remaining to be discovered will be as large, but Brooken "has helped to define a closely related Booch gas play that is still far from fully explored."
That play targets the channel-fill sands within the incised valley that are isolated from the main depositional axis.
