Seismic Evaluation of the Devonian Ohio Shale in the Big Ugly Area, Southwestern West Virginia

LI, ZHENG, and THOMAS WILSON, West Virginia University, Morgantown, WV

The Devonian Ohio Shale was studied in the Big Ugly area of southwestern West Virginia by reprocessing and interpreting existing seismic and geologic data. These data suggest the presence of detached structures above three decollement zones and cross-strike discontinuities associated with the Alleghanian deformation west of Mann Mountain anticline. A basement growth structure, the Griffithsville basement high, localized detached structures along its southeast flank.

High producing trends of gas from the Devonian Ohio Shale occur either near northwest-trending cross-strike structural discontinuities or in northeast-trending detached structures where fracture density should be increased.
