Drilling Activity Summary

Description

A wildcat completion on the Black Hills Uplift was reported by Gulf Exploration in southwestern South Dakota as a discovery in Pennsylvanian Leo (Minnelusa). The Oklahoma City-based company’s #1-10 Fortitude was drilled in Section 10-10s-1e in Fall River County. It initially flowed 74 bbl of 32-degree-gravity oil and 14 bbl of water per day. It was tested on a 12/64-in. choke in Second Leo perforations at 3,440-44 ft and was drilled to 3,680 ft, cased with production pipe to 3,665 ft and plugged back to 3,540 ft. It was tested on a 12/64-in. choke and the flowing tubing pressure was 300 psi. The drillsite is 3 miles northeast of North Hollingsworth Field, an inactive, four-well Leo pool that produced 584 Mbbl of oil, 292 MMcf of gas and 6.85 MMbbl of water between July 1984 and June 1997.
