CHAP Announces Senior Leadership Additions



Oklahoma City, January 29, 2019 — Chaparral Energy, Inc. (NYSE: CHAP) today announced several additions to the company’s senior leadership team, which it has made during the last 18 months. Additions include:

  • Mark Ver Hoeve as Vice President of Geoscience
  • Josh Walker as Vice President of Completions and Operations
  • Clint Calhoun as Vice President of Resource Development

“I am very pleased to announce the addition of Mark, Josh and Clint to Chaparral’s management team,” said Chaparral Chief Executive Officer Earl Reynolds. “Since emerging from restructuring, our strategy has been to divest non-core assets and focus on de-risking and growing our premier STACK and Merge assets. At the same time, we have concentrated on enhancing our existing outstanding operational and technical teams with proven industry leaders that would continue to strengthen our solid execution track record as we create long-term shareholder value. Our core STACK and Merge assets continue to build economic proved reserves and significant drilling opportunities as evidenced by our strong 2018 reserve additions. With their extensive experience and knowledge of horizontal resource plays, Mark and Josh have already played a vital role in our success and we are extremely pleased to welcome Clint to the team. Each of these industry veterans has an integral leadership role in furthering our geological understanding of our acreage, uncovering additional upside and increasing our exceptional operational results in one of America’s most active and economic regions.”
