Arena Resources, Inc. Announces First Quarter 2007 Operations Update.

First Quarter 2007 Production Increases 76% Over First Quarter 2006

Increases 2007 Capital Expenditure Budget to $104 Million

TULSA, Okla. -- Arena Resources, Inc. (NYSE: ARD) ("Arena" or the "Company") today announced its operations update for the first quarter of 2007. During the first 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 March 31, 2007 were approximately 337,000 barrels of oil equivalent (BOE), as compared to production of 192,000 BOE for the same quarter in 2006, a 76% increase, and a 2% increase over the 331,200 BOE produced in the fourth quarter of 2006. Average net daily production increased from 3,600 barrels of oil equivalent per day (BOEPD) in the fourth quarter of 2006 to 3,744 BOEPD.

Arena announced it has also increased its capital expenditure budget for 2007 to $104 million. The increase is primarily due to 20 additional development wells to be drilled on the Company's Fuhrman-Mascho lease in Andrews County, Texas, bringing the estimated total number of new development wells to be drilled on the lease in 2007 to 120. Additional infrastructure improvements and upgrades are also planned.

Mr. Tim Rochford, CEO, stated, "Although we are pleased with our continued progress and development, the production results for the first quarter of 2007 were not at the level we hoped they would be. As we discussed on our year-end conference call, we experienced a number of factors which contributed to an estimated drop in production of approximately 60,000 BOEs, spread over the fourth quarter of 2006 and the first quarter of 2007. Weather, mechanical, refinery and compression issues all played major roles in the overall production results. By the end of March, most of these problems had been resolved resulting in a stabilization of daily production which we anticipate increasing going forward."

The Company performed a re-frac on 12 wells during the quarter and has now re-fraced a total of 79 wells on this lease since initiating its development program.
