Arena Resources, Inc. Provides Fourth Quarter 2004 Operations Update and Announces 2005 Capital Budget of $15 Million
Tulsa, Oklahoma — February 1, 2005 — Arena Resources, Inc. (AMEX: ARD, ARD.WS) ("Arena") ("Company") today announced its operations update for the fourth quarter of 2004 and its capital budget for 2005. In the last three months of 2004, Arena drilled nine wells, six of which were completed and placed in production by year-end. The remaining three wells were completed and placed in production in January 2005. As a result of the newly-drilled wells and the property acquisitions made in 2004, production for the quarter ended December 31, 2004 was approximately 70,500 BOEs, as compared to production of 37,900 BOEs for the same quarter 2003, an 86% increase. December 2004 net daily production was approximately 1,000 BOEs, as compared to production of 420 BOEs in December 2003, an increase of 138%. The 2005 capital budget of $15 million reflects the Company's plans to immediately expand its operations in its Permian Basin properties acquired in 2004, with approximately 80% ($12 million) being allocated to these core properties. The budget includes the drilling of up to 33 development wells, multiple workovers and re-stimulations of existing wells, infrastructure additions and improvements, as well as initiating one waterflood project, expanding an existing waterflood and preparation work on three additional properties for future secondary recovery by waterflood. Arena does not budget for acquisitions; however, the Company will continue to actively pursue future acquisition opportunities.
