Harding & Shelton Exploration LLC has joined with TPH Partners, which is the private equity arm of Tudor, Pickering, Holt & Co. LLC, to form Antioch Energy.

Antioch Energy, which has deep roots in Oklahoma dating back three generations, is led by Kevin Dunnington as CEO and Nathaniel Harding as president. The company, headquartered in Oklahoma City, plans to focus on the acquisition and development of conventional and unconventional oil and gas properties primarily in the Sooner State.

As the company's predecessor, Harding & Shelton Inc., Dunnington and Harding previously built and sold a substantial horizontal redevelopment play in the Western Anadarko basin, according to Antioch's website.

The company changed its name from Harding & Shelton Exploration to Antioch Energy when the formative transaction for an undisclosed value with TPH closed in early September, according to a press release.

Antioch currently operates properties in 10 counties in Oklahoma. The company expects its new partnership with TPH Partners to help provide for substantial growth, the release said.
