Arena Resources, Inc. Revises Reserve Estimates
Tulsa, Oklahoma — July 27, 2004 — Arena Resources, Inc. (AMEX: ARD) ("Arena") Tulsa, announced today that it has amended its Form 10-KSB to reflect a reduction in its estimated total proved oil and natural gas reserves as of December 31, 2003 to a total of 7.61 million barrels of oil equivalent (BOE). This reduction is a result of removing approximately 1.9 million BOE of proved undeveloped reserves from the Dodson lease in Montague County, Texas, from a proved category.

The revised present value, discounted at 10%, of the future net revenues before income taxes ("PV-10") of the Company's proved oil and gas reserves was $66.5 million as of December 31, 2003, using average prices of $29.25 per barrel of oil and $3.46 per Mcf for natural gas.

Arena also announced that it has adjusted its internal estimate of proved reserves to 3 million BOE on the East Hobbs Unit in Lea County, New Mexico acquired on May 7, 2004. This revision results from a reduction of 3.4 million BOE of proved reserves. Following this reduction, Arena's revised PV-10 for the East Hobbs Unit is now $38.7 million.
