Abraxas Provides Operational Results on Exploratory Wilcox Well

Abraxas Petroleum Corporation (AMEX:ABP) today provided operational results on the Gisler #1, an exploratory well targeting the Wilcox formation, located in Karnes County of South Texas.

The Gisler #1 was drilled vertically to a total depth of approximately 13,000′, completed without stimulation and placed on-line approximately two weeks ago. This well is currently producing at a gross rate of approximately 2.9 MMcf of gas and 55 Bbl of condensate per day, or 3.2 MMcfepd. This well may be fracture stimulated in the future. Abraxas Petroleum owns a 63% working interest in this well.

“The production rates from the Gisler #1 are above our expectations. Even though a typical Wilcox well has a relatively steep initial decline rate, these wells are very economic and pay out quickly. We intentionally limit our exploratory budget to 20% of our overall capital expenditure budget. Our upcoming capital projects will focus on projects that are more development and exploitation in nature,” commented Bob Watson, President and CEO of Abraxas.

Abraxas Petroleum Corporation is a San Antonio based crude oil and natural gas exploration and production company with operations principally in Texas and Wyoming. Abraxas Petroleum Corporation also owns a 47% interest in an upstream master limited partnership, Abraxas Energy Partners, L.P., which entitles Abraxas Petroleum Corporation to receive its proportionate share of cash distributions made by Abraxas Energy Partners, L.P.
