South Texas & Gulf Coast

The Company’s presence in the South Texas & Gulf Coast region dates back to 1908 when the founders of the Company acquired approximately 25,000 acres of fee lands in St. Mary Parish, Louisiana. SM Energy continues to receive royalty income from these properties. Presently, the Houston office is primarily focused on the Eagle Ford shale in the Maverick Basin in South Texas. Using two small acquisitions as its entry points in 2007, SM Energy has since built a significant acreage position in the basin through leasing efforts and participation in a joint venture with industry partners. The Company now operates approximately 150,000 net acres of its total 196,000 net acre position. Most of the activity in its operated acreage is focused on the acreage in the rich-gas window of the play where the Company currently has the most favorable economics.
