Brigham Minerals, Inc. is a mineral acquisition company that specializes in acquiring oil and gas mineral rights across the continental United States. The company predominantly holds mineral and royalty interests in several key regions, including the Permian Basin in Texas and New Mexico, the South Central Oklahoma Oil Province and the Anadarko Basin in Oklahoma, the Denver-Julesburg Basin in Colorado, and the Williston Basin in North Dakota. As of the end of 2019, Brigham Minerals owned interests in approximately 57,800 net mineral acres and had stakes in nearly 5,000 productive horizontal wells, encompassing both oil and natural gas. The company was founded in 2012 and is headquartered in Austin, Texas.

ATX Energy Partners is a privately held oil and gas company focused on using advanced technologies to identify and develop unconventional, liquids rich resource plays. Headquartered in Austin, Texas, ATX was founded by the former management team members from Brigham Resources, LLC following the company’s sale of substantially all of its southern Delaware Basin assets to diamondback energy for $2.55 billion. At the time of the sale to Diamondback in February 2017, Brigham Resources was producing 8,500 Boe per day from its 80,185 net acres located in Pecos and Reeves counties, Texas. Their management team has a long history of identifying, acquiring, delineating and developing early stage domestic resource plays. Prior to forming Brigham Resources, a subset of their management team oversaw the identification, acquisition, delineation and development by Brigham Exploration Company of approximately 375,000 net acres in the Williston Basin prior to its December 2011 sale to Statoil ASA for $4.4 billion. At present, ATX is evaluating resource opportunities in the U.S. Lower 48. Historically, the team has focused on early stage “frontier” opportunities that lack meaningful horizontal drilling validation, but would also consider partially delineated opportunities that have yet to fully benefit from an optimal drilling and completion formula. Going back to work in the Permian Basin and/or the Williston Basin would be two obvious alternatives, given the ATX team’s success in both of those basins. ATX is also currently evaluating opportunities in selected basins in the Rockies.
