The acreage comprises fee, state and federal leases located in Southern Wyoming in Laramie County. Mariner believes the acreage is on trend with and contains shales with petrophysical properties similar to the commercial Niobrara Shale discoveries of the Jake 2-01H well and Silo Field.

Scott Josey, chairman, CEO and president of Mariner Energy, said: “This acquisition is consistent with our stated strategy of obtaining sizeable low-entry-cost oily shale plays where we can operate.

“The acreage is close to existing infrastructure, facilitating development if our exploration efforts are successful.”

Mariner Energy is an independent oil and gas exploration, development, and production company headquartered in Houston, Texas, with principal operations in the Permian Basin, Gulf Coast and the Gulf of Mexico.
