TULSA, Okla. -- Arena Resources Inc. (AMEX: ARD) ("Arena" or the "company") today announced its operations update for the third quarter of 2005. During the third quarter, Arena drilled 12 wells on its Fuhrman-Mascho lease, making a total of 22 new wells drilled since securing a rig in mid-April, and re-stimulated nine existing wells, making a total of 14 well re-stimulations in 2005 using both the "lite-prop" and sand processes. The company has had a 100% success rate on wells drilled and completed on this lease this year, with flush production ranging from 50 BOEPD (Barrels of Oil Equivalent Per Day) to more than 175 BOEPD. Additionally, the company continued to improve the infrastructure on selected properties, acquired additional acreage and drilled three exploratory wells on its Syracuse and Rocky prospects in Kansas, and converted one additional well into an injector well on its East Hobbs lease in New Mexico in preparation for secondary recovery. The company also completed the acquisition of approximately 720 acres in the Permian Basin that has current production as well as development opportunities.

The company received a private equity investment of $10 million in July. The proceeds allowed the company to increase its capital expenditure budget for the remainder of 2005 to $18.5 million and pay off the remaining debt on its bank credit facility. The company also received approximately $10.7 million in proceeds from the exercise of its outstanding publicly traded warrants following their call for redemption in late August, which was completed in early October 2005.

Production for the quarter ended Sept. 30, 2005 was approximately 141,000 BOE, as compared to production of 63,552 BOE for the same quarter in 2004, a 122% increase, and a 32% increase over the 106,394 BOE produced in the second quarter of 2005. Average daily production increased from 1,169 BOEPD in the second quarter to 1,534 BOEPD. Oil and gas revenues for the third quarter of 2005 are estimated to be $7.75 million, as compared to $2.5 million for the same period in 2004, a 210% increase, and a 68% increase over the $4.6 million generated in the second quarter of 2005.
