Hi-Crush Partners LP said May 22 that Michael Alan Oehlert will join the Houston-based frac sand provider’s executive team as COO.

Oehlert joined Hi-Crush in 2017 as vice president of the company’s PropStream business. He was recently promoted to senior vice president of PropStream in January.

“We are excited for Alan to take on this expanded role within our leadership team,” Robert E. Rasmus, chairman and CEO of Hi-Crush, said in a statement on May 22. “Alan is a well-respected, seasoned energy executive, bringing nearly four decades of oilfield services experience and a deep knowledge base across our operations.”

With the appointment of Oehlert as COO, Rasmus will cease serving as the principal operating officer of Hi-Crush, but will continue in his role as chairman and CEO. The appointment took effect on May 21.

Prior to joining Hi-Crush, Oehlert provided consulting services to various private equity firms. Previously, he led Patriot Artificial Lift LLC and, before that, Downhole Technology LLC as president and CEO. He also previously served various manager-level operations positions at Integrated Production Services, now a division of SPN Well Services, and US Plungers and Scientific Microsystems Inc.

“Alan’s unique set of experiences will help to ensure industry-leading execution on behalf of our customers, while at the same time, position him to spearhead the efficient integration and delivery of our expanding suite of last mile services, including our recent logistics-focused acquisitions of the PropDispatch software and Pronghorn Logistics,” Rasmus continued. “We look forward to Alan leading the execution of our strategy to deliver the most comprehensive solutions offering in the industry, as we continue our transformation to a proppant logistics company.”

Hi-Crush owns and operates multiple frac sand mining facilities and in-basin terminals, and provides mine-to-wellsite logistics services to optimize proppant supply in all major oil and gas basins in the U.S., according to the company press release.
