Sanchez Energy Corp. (NYSE: SN) said Oct. 29 that Cameron W. George has been appointed as interim CFO following the resignation of Howard J. Thill from the Houston-based oil and gas producer in the Eagle Ford Shale.

Thill resigned from Sanchez Energy to pursue other opportunities and was not related to any disagreements regarding financial disclosures, accounting matters or other business issues, according to the company press release.

George, whose appointment as interim CFO was effective immediately, has more than 15 years of investment banking and industry experience in oil and gas. He previously led the finance team at Linn Energy LLC from 2005 until he joined Sanchez Energy in 2016 as senior vice president of capital markets.

Tony Sanchez III, who on Oct. 29 was also appointed as president in addition to his current position as CEO, said the leadership changes help set the stage for the next phase of the company’s corporate development.

“Cam has demonstrated tremendous leadership in the company transformational initiatives over the past two years, and we are pleased that he is stepping up to take a larger role with the company,” Sanchez said in a statement. “With his unique industry experience and extensive financial and accounting knowledge, he will play a key role in developing and implementing a corporate strategy that supports the company’s continued development.

Additionally, Eugene I. Davis, chairman and CEO of Print Consulting Group, and Adam C. Zylman, cofounder of Sunland Capital, were also appointed to Sanchez Energy’s board on Oct. 29 as independent directors.

Sanchez Energy is an independent E&P focused on the Eagle Ford Shale in South Texas, where the company has a roughly 283,000 net-acre position with more than 1 billion barrels of oil equivalent of resource potential, according to the company’s September investor presentation.

Earlier this year, Chris D. Heinson, the company’s previous senior vice president and COO, also resigned from Sanchez Energy to take the CEO job at Maverick Natural Resources LLC, a portfolio company of EIG Global Energy Partners previously known as Breitburn Energy Partners.
