LARGE SCALE FOAM FRACTURING IN THE DEVONIAN SHALE - A FIELD DEMONSTRATION IN WEST VIRGINIA

摘要

This report describes a large-scale foam fracturing operation performed on a Devonian Shale well in Jackson County, W. Va. Here the Energy Research and Development Administration (ERDA) in cooperation with Consolidated Gas Supply Corp. (CGSC) conducted a foam frac using 973 bbl. water, 2160 MSCF nitrogen, and 155,000 lbs sand proppant. The gross perforated formation interval is 3238-3629 ft. in W. L. Pinnel No. 12041 near Cottageville, Jackson County. The frac test was conducted to help evaluate the effectiveness of foam fracturing in the low-pressure watersensitive Devonian Shale of the Appalachian Basin.
