Adjusts 2006 Capital Expenditure Budget Up to $65 Million
Tulsa, Oklahoma — January 27, 2006 — Arena Resources, Inc. (AMEX: ARD, ARD.WS) ("Arena") ("Company") today announced its operations update for the fourth quarter of 2005. In the last three months of 2005, Arena drilled 20 development wells and one exploratory well, 12 of which were completed and placed in production by year-end. The remaining eight development wells and one exploratory well are in varying stages of completion and will be placed in production in early 2006. In addition, the Company performed ten re-fracs and re-completions in the fourth quarter of 2005. For the full year of 2005, the Company drilled 42 development wells, with 34 wells being completed and placed in production by year-end. The Company had a 100% success rate on development wells drilled and completed in 2005. The Company also performed 24 re-fracs and participated in the drilling of two exploratory wells, completing one and awaiting completion on the other.

As a result of the continuing development program, net production for the quarter ended December 31, 2005 was approximately 171,000 BOEs, as compared to net production of 72,965 BOEs for the same quarter in 2004, a 134% increase, and as compared to 141,429 BOEs for the third quarter 2005, an increase of approximately 21%. December 2005 net daily production was approximately 2,050 BOEs, as compared to daily production of 1,000 BOEs in December 2004, an increase of 105%. Total production for 2005 was approximately 508,000 BOEs compared to 223,333 BOEs for 2004, a 127% increase.

Arena also announced it is adjusting its 2006 capital expenditure budget from $60 to $65 million. This increase reflects the Company’s plans to accelerate the development schedule of its operations in its Permian Basin properties, with approximately $45 million being allocated to its Fuhrman-Mascho lease in Andrews County, Texas. The budget includes the drilling of a minimum of 120 development wells, multiple workovers and re-stimulations of approximately 36 existing wells, initial development work on the Yates gas formation on the Fuhrman-Mascho lease and infrastructure additions and improvements. Arena does not budget for acquisitions; however, the Company will continue to actively pursue future acquisition opportunities.

Mr. Tim Rochford, Arena's President and CEO stated, "The development program implemented on our Fuhrman-Mascho lease in April, 2005 was a big factor in more than doubling our production for the year. Of the 44 wells we drilled in 2005, 36 were on this lease. In 2006, we plan to drill a minimum of 120 development wells with approximately 85 of these on the Fuhrman-Mascho where we have had a 100% success rate to date. We have accordingly increased our capital expenditure budget from $28 million in 2005 to $65 million for 2006. Although we are focusing our efforts on the development of our current leases, we will continue to actively pursue strategic acquisitions in 2006 that compliment our existing properties."
