Arena Resources, Inc. Announces Record Second Quarter 2007 Production.

Second Quarter 2007 Production Increases 60% Over Second Quarter 2006

TULSA, Okla. -- Arena Resources, Inc. (NYSE: ARD) ("Arena" or the "Company") today provided its operations update for the second quarter of 2007. During the second quarter, Arena drilled 28 new development wells, and re-stimulated 12 existing wells, all on its Fuhrman-Mascho lease in Andrews County, Texas. The Company continues to have a 100% success rate on wells drilled and completed on this lease.

Sales as a result of production for the quarter ended June 30, 2007 rose to approximately 385,000 barrels of oil equivalent (BOE), as compared to production of 241,060 BOE for the same quarter in 2006, a 60% increase, and a 14% increase over the 336,694 BOE produced in the first quarter of 2007. Average net daily production increased from 3,744 barrels of oil equivalent per day (BOEPD) in the first quarter of 2007 to approximately 4,230 BOEPD. Production continued to be adversely affected by inclement weather and power outages in the Permian Basin and the Oklahoma Panhandle and pipeline and refinery disruptions in Oklahoma and Kansas.

Arena announced in May 2007 the purchase of a second drilling rig, currently being completely refurbished, assembled and readied for operation by late September 2007. The rig, capable of drilling to a depth of 9,000 feet, will cost approximately $2.5 million, including additional drill pipe, drill collars and other ancillary equipment and will be the second Company-owned rig working exclusively at Arena's Fuhrman-Mascho leases. The Company has also added a contract rig to drill a minimum of ten wells at the Fuhrman-Mascho beginning in early August.

In June, the Company announced it had signed a letter of intent to produce and sell gas from its Fuhrman-Mascho properties to Aspen Pipeline ("Aspen") of Houston, Texas. The gas, produced from the Yates formation, has a high nitrogen content and has often been considered too costly to produce because of the need to remove the nitrogen before transporting. Aspen announced in February 2007 a Memorandum of Understanding with Texas Independent Energy ("TIE") that could lead to the construction of a dedicated pipeline to TIE's 1,000-megawatt energy generation facility just outside Odessa, Texas, which can consume a blend containing Yates formation gas without removing the excess nitrogen. A definitive agreement between Arena and Aspen is expected to be signed shortly, whereby Arena will then commence a re-completion program on up to 90 existing idle well bores to the Yates formation by October 2008.

Also in June, Arena announced the completion of a registered direct common stock offering. The Company issued 2,050,000 shares of its common stock to selected institutional investors at a price of $49.00 per share, resulting in net proceeds of approximately $95.3 million. The Company intends to use the net proceeds from the offering for debt repayment, drilling and development of its current properties, capital expenditures and general working capital.

Mr. Tim Rochford, CEO, stated, "Despite some continuing disruptions, we were able to achieve record production results in the second quarter. With the successful stock offering in June, we have positioned ourselves to continue an aggressive development program throughout 2007 and 2008. In addition to our normal development activity, we will be very active during the remainder of 2007 developing Yates gas wells in anticipation of the arrival of a transmission pipeline during the second quarter of 2008. We continue to look at acquisition opportunities and have 100% of our $150 million credit facility available."
