Arena Resources, Inc. Adds an Estimated Eight Million Barrels of Oil Equivalent of Proved Reserves in West Texas
Tulsa, Oklahoma — December 12, 2007 — Arena Resources, Inc. (NYSE-ARD)(“Arena”)(“Company”) announced today that it has acquired two properties located in Andrews County, Texas for a purchase price of $49 million. The purchase price was financed by existing cash reserves and drawing on the Company’s $150 million credit facility. The closing date was December 11, 2007 with an effective date of December 1, 2007.

Property Information
The properties consist of approximately 5,000 acres. Arena will be the operator and have a 100% working interest and average net revenue interest in excess of 75% in these properties. One of the properties is located in the Fuhrman Macho field immediately adjacent to the Company’s  Fuhrman-Mascho properties acquired in December 2004. In addition to the producing wells currently on the properties, Arena’s engineering team has identified approximately 120 new drilling locations, with the potential to increase that number through additional in-fill drilling and development. In addition to the current production from the San Andres and Queen formations, the Company has also secured the rights to the Yates gas formation throughout the acreage. 

Production and Reserves
The current net production to the Company from the properties is approximately 560 BOE (Barrels of Oil Equivalent) per day and is over 85% oil. The Company’s initial reserve estimates, as determined by internal engineering evaluations, indicate the properties have an estimated eight million BOEs of proved reserves net to Arena, exclusive of any potential Yates gas reserves and any additional probable or possible oil reserves. The proved reserves represent an estimated cost of $6.00 per BOE and are approximately 10% proved developed producing.     

Mr. Tim Rochford, CEO of Arena stated, “These acquisitions allow us to add significant reserves and drilling locations to our current inventory in the Fuhrman-Mascho at a very attractive price as we continue to focus on those acquisitions that will compliment our existing Permian Basin properties.”
