Geostatistical (kriging) study of geological and gas production data from West Virginia

Technical Report ·
OSTI ID:6165677
As part of the Unconventional Gas Program/Eastern Devonian shale research, we carried out geostatistical (kriging) analyses of geological and gas production data from southwestern West Virginia. The geological parameters studied consist of the top and bottom elevations of the Greenbrier limestone and Berea sandstone, the bottom elevation of the Devonian shale, and the thickness of the Greenbrier and Berea. The production data consist of rock pressure and ten year cumulative production. No gross correlation between the geological and production data is obvious. However we note that low values of ten year cumulative production are generally found in the vicinity of the Warfield anticline while high values of ten-year cumulative production are located in the NW limb of the anticline. Both rock pressure and ten year cumulative production can be reasonably estimated within the study area. 5 refs., 28 figs.
