Arena Resources Inc. Provides Second Quarter 2006 Operations Update; Second Quarter 2006 Production Increases 126% Over Second Quarter 2005.

TULSA, Okla. -- Arena Resources Inc. (AMEX: ARD) ("Arena" or the "company") today announced its operations update for the second quarter of 2006. During the second quarter, Arena drilled a total of 35 new wells; 20 wells on its Fuhrman-Mascho lease in Andrews County, Texas, seven wells on its Seven Rivers Queen lease in Lea County, N.M., four wells on its Auntie Em lease in Gray County, Kan., two wells on its Rocky Prospect in Greeley County, Kan., and two exploratory wells on its Syracuse Prospect in Hamilton County, Kan. In addition, the company re-stimulated 13 existing wells on its Fuhrman-Mascho lease and five on its Seven Rivers Queen lease.

Production for the quarter ended June 30, 2006, was approximately 240,000 BOE, as compared to production of 106,000 BOE for the same quarter in 2005, a 126% increase, and a 26% increase over the 191,000 BOE produced in the first quarter of 2006. Average net daily production increased from 2,133 BOEPD in the first quarter of 2006 to 2,637 BOEPD in the second quarter. Oil and gas revenues for the second quarter of 2006 are estimated to be $14.5 million, as compared to $4.6 million for the same period in 2005, a 215% increase, and a 40% increase over the $10.38 million generated in the first quarter of 2006.

In May, the company received approximately $30.3 million in net proceeds from the private sale of 1,150,000 shares of the company's common stock to institutional investors. The funds will be used to bridge the deficit between estimated 2006 cash flow and the current 2006 CAPEX budget of $65 million, and allow the company to keep 100% of its credit facility available.

Tim Rochford, president & CEO stated, "We are extremely pleased with the results of the second quarter. We continue to execute our development plan and add acreage to our core properties while continuing to seek acquisition opportunities. We now have two full-time drilling rigs working on our Furhman-Mascho lease and plan to increase the re-fracs of existing wells from 36 to 50 for 2006. We have been able to accelerate our drilling schedule in Kansas and New Mexico due to rig availability, and after determining the results from these wells we will then re-evaluate our CAPEX budget for the remainder of 2006."
