Cardinal River Energy Co

Cardinal River Energy Company was founded in 1987 as a small exploration and production company. In late 2006, the company formed a strategic partnership with several privately held Oklahoma City based energy companies. These companies consolidated their oil and gas interests into Cardinal River Energy I LP. Through its early years, the company focused its business strategy on being a low cost, non-operating working interest owner in a diverse portfolio of oil and gas assets. As the company continued to grow and began generating its own prospects, the company formed Cardinal River Operating, LLC as an operating affiliate to drill, manage and operate the company's internally generated prospects. Today, as a result of the general partner's selective acquisition and participation strategies, the Partnership now owns operated and non-operated working interests, royalty interests and overriding royalty interests in over 1000 wells and properties located in several states including Oklahoma, Kansas, Arkansas, Texas, New Mexico, Mississippi, Illinois and Louisiana. ​ Cardinal River Energy is also the parent company of River Rock Energy Company and River Rock Operating, LLC. River Rock Energy owns over 2,000 oil and gas wells in Oklahoma and Kansas, with over 2,300 miles of gas gathering and gas processing assets. River Rock Operating, LLC is the operator of all of River Rock Energy's wells and gas gathering assets.
