Permian

SM Energy has had a presence in the Permian Basin since the mid-1990s, but became far more involved in the basin with its acquisition of Wolfberry tight oil assets in late 2006. The acquisition provided the necessary critical mass to open a regional office in Midland, Texas. More recently, the Company has shifted its focus to other areas of the Permian basin, including more recently acquired acreage in the northern Midland basin where the Company is focused on delineating Mississippian lime acreage.
