Drilling Activity Summary


U.S. Energy Development Corp. has completed two producers in Zavala County (RRC Dist. 1), Texas. The Briscoe Ranch Field wells are on a 1,936-acre lease in Section 102, Mary A. Chrisholm Survey, A-874, and the laterals bottomed 2 miles northwest in Section 9, Maria Escolustica Diaz Survey, A-107. The #1EF A LLM North flowed 361 bbl of 34-degree-gravity crude, 192 Mcf of gas and 1.096 Mbbl of water per day. Production is from commingled Cretaceous perforations ranging from Austin Chalk at 5,616 ft to Eagle Ford Shale at 16,749 ft. Tested on a 26/64-in. choke, the flowing tubing pressure was 360 psi. The northwest-trending horizontal well was drilled to 16,935 ft, 4,995 ft true vertical. The offsetting and parallel #2EF A LLM North produced 249 bbl of 35-degree-gravity crude, 143 Mcf of gas and 1.253 Mbbl of water through commingled perforations in Austin Chalk at 5,615 ft to Eagle Ford at 16,795 ft. The flowing tubing pressure was 360 psi when tested on a 26/64-in. choke. The horizontal sidetrack was drilled to 16,930 ft, 4,967 ft true vertical. U.S. Energy is based in Getzville, N.Y.
