Oklahoma City-based GMX Resources Inc. has hired Global Hunter Securities to help it sell a portion of the company’s Cotton Valley Sand liquids-rich natural gas properties in East Texas. A transaction is expected during the third quarter, GMX said. The company’s natural gas resources are in the East Texas Basin, in the Haynesville/Bossier shale and the Cotton Valley Sand Formation, where the majority of its acreage is contiguous, with infrastructure in place and substantially all held by production, GMX said. In early 2011 GMX branched out from its Haynesville/Bossier properties and acquired about 67,724 net acres within the core horizontal oil development areas of the Bakken/Sanish-Three Forks Formation in the Williston Basin and the Niobrara Formation in the Denver-Julesburg Basin (see Shale Daily, Feb. 2, 2011).
