Mississippian Structure and Hydrocarbon Potential of Buchanan, Dickenson, and Wise Counties, Virginia

Frank H. Jacobeen, Jr.

Correlation of the Mississippian interval in over 500 petrophysical logs from the top of the Greenbrier Limestone through the Berea Sandstone and the construction of four structure maps and four isopach maps show that structure is not a prime factor in controlling gas production in Buchanan, Dickenson, and Wise Counties, Virginia. A total of 889 wells tested 26% of the acreage in these three counties; operators completed 781 of these as gas wells. Through December 1986, cumulative gas production from Buchanan, Dickenson, and Wise Counties was reported to be 147 bcf. Remaining proven producible gas reserves are 235 bcf. The average completed well ultimately should produce over 500 mmcf of gas. Based on this record, it is estimated that an additional 815 bcf of recoverable as is to be found on the undrilled 74% of Buchanan, Dickenson, and Wise Counties, Virginia.
