Rimer joins Whiting from Noble Energy Inc. (NYSE: NBL), where he previously served as senior vice president of global services. His appointment at Whiting, where he will be responsible for the operations, drilling, reservoir engineering, environmental health and safety and land for the Rockies-focused operator, is effective Nov. 15.

Whiting CEO Bradley Holly said in a statement: “With Chip on the team, we have completed our transition from a function based, hierarchical structure to a dynamic, team-based organization. Our C-suite now consists of four pillars of responsibility that will underpin Whiting’s future success.”

The hiring of Rimer follows the recent appointment by Whiting of Tim Sulser as chief corporate development and strategy officer.

Sulser joined Whiting in September from Salt Creek Oil and Gas LLC, a company he founded and led as CEO. He also previously served as a director of investment banking for Tudor, Pickering, Holt & Co. for five years, most recently heading the firm’s Denver office.

In the company’s September announcement, Holly said Sulser would be working with the team “to ensure that Whiting is maximizing the value of its high-quality asset base while systematically planning for the future.”

Whiting’s C-suite now consists of Holly as chairman, president and CEO, a financial division led by CFO Mike Stevens, a strategy and planning division led by Sulser and an operating division headed by Rimer.

Rimer began his career with ARCO Oil & Gas Co. in 1983 working U.S. onshore areas and he held senior operations engineering positions at Vastar Resources and Aspect Resources before joining Noble Energy in 2002. He holds a degree in petroleum engineering from the University of Texas.

Rimer said in a statement: “Whiting has a strong reputation for operational efficiency, safety, and community and environmental stewardship. It has assembled a premier field operations team across its assets. In addition, it has a strong team at corporate headquarters with a reputation for achieving the highest levels of technical competence. I am excited to be part of the Whiting leadership team and to do my part to ensure our people have the resources and guidance they need to achieve industry-leading standards of operational excellence.”

Whiting holds more than 460,000 net acres across the Williston Basin of North Dakota and Montana. Earlier this year, the company announced plans to exit its 100,000-acre position in the northeastern Denver-Julesburg Basin in order to focus all its attention on the Bakken in North Dakota.

“The Bakken core has some of the best wells in the U.S. It generates strong free cash flow,” Holly said at Hart Energy’s DUG Rockies conference and exhibition in April 2018. Further, it’s a “true oil play,” he added.
