Company Profile

Wolverine is a privately owned, independent oil and gas exploration and production company based in Grand Rapids, Michigan.  Since 1948 and over three generations, the Jansma family has been successfully and responsibly developing oil and gas reserves to meet our nation’s energy needs.
In 2000, Wolverine went into an area all but abandoned by the major oil companies: south-central Utah. Wolverine’s exploration team studied this complex region for several years before drilling its first prospect. The result? Covenant Field, the largest onshore conventional discovery in North America in the previous 30 years.
