Harrison Williams was appointed as CEO of The Oil & Gas Asset Clearinghouse, the Houston company said April 14.

Ken Olive, former CEO, and Ron Barnes, former COO, are taking other opportunities after more than 18 years at the Clearinghouse.

The appointment was effective April 13, the company said.

Williams was a principal in A&D for more than 25 years at Albrecht & Associates. He also has experience in E&P, the company added. He holds a bachelor’s degree from Harvard College and a master’s degree from Massachusetts Institute of Technology.

“I am thrilled to join the Clearinghouse team," Williams said in a statement. "I’ve respected their innovative solutions to create liquidity for a wide breadth of client assets, from individual wells to entire fields, while leveraging their deep technical expertise to complete larger negotiated transactions, for years. There is no other firm that can claim over 32,000 completed transactions. I very much look forward to bringing my experience and engineering acumen to clients as we further develop and invest in our talented technical team, our unique hybrid auction and our online infrastructure."

Clearinghouse is a CenterGate Capital portfolio company.
