A group of energy-focused private equity funds managed by New York-based energy and power-focused private equity firm Riverstone Holdings LLC has made an undisclosed capital commitment to Fort Worth, Texas-based Titan Operating LLC .

Titan Operation is an E&P focused on acquisitions and development in the Barnett shale in North Texas.

Hollis Sullivan is co-founder and chairman of Titan. He has more than 20 years E&P experience in the Barnett shale. Mark Schumacher and Christopher Hammack are co-founders and managing partners. Schmucher was in charge of the Barnett shale development program for EnCana Oil & Gas USA. Hammack led the drilling and completions activities for Range Resources, where he managed that company’s Barnett shale division.

Riverstone managing director Greg Beard says, “With the increased activity in the Barnett shale over the last several years, a partnership with operators as experienced as Hollis, Mark and Chris represents a unique opportunity for Riverstone. We are excited to support such seasoned executives with a depth of relationships and history in the Barnett.”

Sullivan says, “A partnership with a firm as well-regarded as Riverstone is a milestone event for Titan. We believe that the opportunities in the Barnett, coupled with the sponsorship and support of a world-class private equity partner, have the potential to elevate Titan to become a significant player in the basin.” SJP
