As a result of Thom's appointment, which is effective Aug. 28, Hugh Menown has resigned as executive vice president, chief accounting officer and interim CFO to pursue other interests, the release said. Menown has agreed to serve as an advisor to Energy XXI during a transition period.

Thom has more than 20 years of financial and operational experience in the energy industry, primarily offshore Gulf of Mexico operations, according to the company press release. Most recently, she served as the CFO of KLR Energy Acquisition Corp. from January 2015 until April, when it combined with Tema Oil and Gas Co. to form Rosehill Resources Inc. (NASDAQ: ROSE).

In addition, Thom served in positions of increasing responsibility for EPL Oil & Gas Inc. from October 2000 until being acquired by the company's predecessor, Energy XXI Ltd., in June 2014. Prior to that, she served as senior reservoir engineer for Exxon Production Co. and ExxonMobil Corp. (NYSE: XOM).

Thom has served as a director of Patterson-UTI Energy Inc. (NASDAQ: PTEN) and also Yates Petroleum Corp., during which Energy XXI CEO Douglas E. Brooks previously headed. She holds a B.S. in Engineering from the University of Illinois and a Masters of Business Administration in Management with a concentration in Finance from Tulane University.

"[Thom's] experience and proven leadership, as well as her familiarity with a significant portion of our asset base, will serve our company and its stockholders well," Brooks said in a statement. "Having worked with T.J. before when she served on the Yates board of directors, I have seen her talents, her breadth of knowledge about the oil and gas industry, and her commitment to strong corporate governance and controls."

Energy XXI Gulf Coast is an independent oil and natural gas development and production company whose assets are primarily located in the U.S. Gulf of Mexico waters offshore Louisiana and Texas.
