Penn Virginia Corp., based in Radnor, Penn., is testing a wildcat in Washita County, Okla., that is producing from the Des Moines Granite Wash through fracture-stimulated perforations between 12,429 and 16,950 ft. The #2-6H McGurk, located in Section 6-11n-16w, flowed gas at an initial rate of 11.2 MMcf/d with 792 bbl of 64-gravity condensate and 1,152 bbl of water daily. The well was tested on a 23/64-in. choke, and drilled to 17,000 ft total depth with a true vertical depth of 12,184 ft.

Another Des Moines Granite Wash producer is just five miles southwest of the #2-6H McGurk. Penn Virginia-Chesapeake Operating Co.’s #1-27H Janzen has been tested flowing 15.5 MMcfe/d of gas. Located in Section 27-11n-17w and owned 19% by Chesapeake, the well is producing from a lateral extending to the northwest portion. According to IHS Energy Inc., Penn Virginia plans to have three rigs working on recently acquired nearby acreage by the end of 2010.

Granite Wash wells were also completed in Texas. Tyler, Texas-based Mewbourne Oil Co. recently completed two Granite Wash wells in Hemphill County (RRC Dist. 10), Texas. The #1895H Leslie Webb et al, located in Section 189, Block C, G&MMB&A Survey, A-518, initially flowed 4.23 MMcf of gas, 180 bbl of 58-gravity condensate and 13 bbl of water per day. The horizontal producer is producing from an openhole Des Moines Granite Wash interval between 10,050 and 11,818 ft. It was drilled southwestward and fracture stimulated from 10,285 to 11,769 ft Shut-in and flowing casing pressures were gauged at 2,790 psi and 1,825 psi, respectively, on a 16/64-in. choke.

In the same pad, the #1896H Leslie Webb et al flowed 5.28 MMcf of gas, 223 bbl of 61-gravity condensate and 344 bbl of water daily. Fracture-stimulated, openhole lateral perforations are located between 10,002 and 12,521 ft, according to IHS Energy Inc. Shut-in casing pressure was 3,060 psi, and the flowing casing pressure was 1,800 psi on a 20/64-in. choke.
