River Rock Energy Company and River Rock Operating, LLC are wholly owned subsidiaries of Cardinal River Energy Co.  The River Rock companies own and operate over 2,500 oil and gas wells in Oklahoma and Kansas with over 2,300 miles of gas gathering and gas processing assets. The companies are headquartered in Oklahoma City, Oklahoma, and are engaged in oil and gas exploration, production, gathering, processing and marketing operations. Our strategy is to maximize value through the following:

• Continue to develop the company’s leases and grow its oil and gas reserves at very low finding costs.
• Carefully monitor production costs, optimize production operations, and minimize lifting costs.
• Utilize prudent risk management and hedging practices to lock-in favorable oil and gas prices and protect against downside price movements.
• Enhance value through the growth of marketing and midstream business operations.
