U.S. Energy Enters Second Eagle Ford Agreement

U.S. Energy Corp. has entered into a second participation agreement with Crimson Exploration Inc. to acquire an interest in an Eagle Ford oil prospect and associated leases located in Zavala and Dimmit Counties, Texas.

Under the terms of the agreement, USE will acquire 30% of Crimson's working interest (~23% net revenue interest) in approximately 7,186 acres (2,156 acres net to USE). All of the leases are currently held by production and produce approximately 200 gross BOE/D (46 net BOE/D) from the Austin Chalk formation. It is estimated that under current spacing there is a potential for up to 44 gross (13.5 net) drilling locations on the acreage. All drilling and leasing on this prospect will be on a heads up basis. This acquisition brings USE's total acreage in the Eagle Ford to approximately 11,861 gross acres (3,558.5 acres net to USE) with the potential for up to 70 gross and 21.3 net Eagle Ford drilling locations. The prospect also has additional Austin Chalk and Buda formation production potential. For competitive reasons, the financial terms of the transaction will not be disclosed at this time.

The prospect is in the Eagle Ford shale oil window in Zavala and Dimmit Counties, Texas. Crimson will operate and tentatively plans to spud the first horizontal well in the prospect in October 2011. The well is planned to be drilled to a total drilling depth of 12,500 feet (~6,000 ft. vertical, ~6,500 ft. horizontal), and to be completed with 15 to 20 fracture stimulation stages.

"We are pleased to announce another oil venture with Crimson Exploration. These assets complement our existing Leona River acreage and provide both U.S. Energy and Crimson with a potential multi-year drilling inventory in the Eagle Ford oil window," stated Keith Larsen, CEO of U.S. Energy Corp. "We look forward to drilling our first well on this acreage in the near future and to continue seeking additional Eagle Ford opportunities with Crimson as well," he added.
