Houston-based Sanchez Energy Corp. (NYSE: SN) appointed Chris Heinson as interim chief operating officer after Joseph DeDominic’s resignation, the company said Dec. 26. DeDominic, chief operating officer and senior vice president, will pursue another opportunity, the company added.

"We greatly appreciate Joe's valuable contributions to the company and wish him and his family all the best in his new endeavor," Tony Sanchez Jr., Sanchez Energy's executive chairman, said.

Heinson is currently senior manager of reservoir engineering. His new responsibilities begin in January 2014, the company said.

“Following on Joe's leadership and our record of accomplishments this year, we are in a strong position to achieve sustainable growth, both operationally and financially and we are looking forward to an outstanding 2014,” Sanchez Jr. added.

Sanchez Energy’s current net production is roughly 20,000 barrels of oil equivalent per day (BOE/d), Sanchez Jr. said. The company should exceed the top end of its current quarter guidance, he added.

 The company, an independent E&P, is focused on unconventionals, onshore, on the U.S. Gulf Coast. The Eagle Ford shale holds 125,000 net acres for the company, and the Tuscaloosa Marine shale has 40,000, the company said.

Heinson worked previously for Occidental Petroleum Corp. and holds a BS degree in Petroleum Engineering from the University of Texas at Austin.
