History

Whiting Petroleum Corporation was founded in January, 1980 in Denver, Colorado by Kenneth R. Whiting, with co-founder Bert Ladd. Mr. Whiting served as President and Chief Executive Officer until 1993. In 1983, the company merged with Keba Oil & Gas and Hingeline-Overthrust to become a public company.

In 1992, Alliant Energy, a Midwest public utility, acquired Whiting Petroleum Corporation for $27.5 million. In November, 2003, Whiting again became a public company when our IPO was completed at $7.75 per split share.

Since our founding, we have been an independent oil and gas company that acquires, exploits, develops and explores for crude oil, natural gas and natural gas liquids, primarily in the Rocky Mountain States and the Permian Basin.  Today Whiting is focused in the Rocky Mountain region of the United States.
