Effective Aug. 1, Correne S. Loeffler will serve as Whiting’s CFO. She joins the Denver-based company from Callon Petroleum, where she was vice president of finance and treasurer since April 2017.

Loeffler succeeds Michael J. Stevens, who is stepping down after an 18-year career with Whiting. He has served as Whiting CFO since 2005.

Bradley J. Holly, Whiting’s president, chairman and CEO, thanked Stevens in a statement for his leadership and wished him the best in the future.

Holly also welcomed Loeffler, whose background includes 14 years of financial experience in the oil and natural gas industry, to the company.

“Correne’s financial experience in the oil and natural gas industry will complement our management team very well,” he said in the statement on July 16.

Loeffler initially joined Callon in April 2017 as its treasurer. She also served as Callon’s interim CFO starting in June 2017 until the company appointed James “Jim” Ulm II to fill the role in December 2017.

Prior to Callon, she worked as an executive director in the corporate client bank group at JPMorgan Securities LLC for roughly a decade. While at JPMorgan, she had served as Callon’s relationship manager beginning in 2013.

She began her career as a consultant at Accenture in 1999 and also went on to work as an associate in Bank of America’s Global Corporate & Investment Bank.

At Whiting, Loeffler will join a company focused primarily in the Rocky Mountains region of the U.S. The company’s largest projects are in the Bakken and Three Forks plays in North Dakota and Montana and the Niobrara shale play in northeast Colorado.
