Antero Resources continues to progress on shale projects throughout the U.S. Antero's current gross operated production is 222 thousand cubic feet per day (MMcf/d) and 190 thousand cubic feet of natural gas equivalent per day MMcfe/d net (including non-operated production), comprised of 180 MMcf/d of gas and 1,700 Bbl/d of NGLs net.

Marcellus Shale

Antero is operating five drilling rigs in the Marcellus Shale play, all of which are drilling in northern West Virginia. Antero has 128 MMcf/d of gross operated production primarily from 34 horizontal wells online resulting in 90 MMcf/d of net production. The company estimates that an additional 20 MMcf/d of gross operated deliverability from two completed wells is waiting on pipeline and facilities completion. Antero expects to turn these two wells to sales by June when the Jarvisville Lateral is completed as a southerly extension to the Bobcat Lateral (formerly known as the Clarksburg Lateral) and 46 MMcf/d of compression capacity is commissioned at a new third party owned compressor station. The Tichenal Lateral, a southerly extension to the Jarvisville Lateral, is expected to be completed in July which will add another 46 MMcf/d of compression capacity to the system. Antero has nine additional horizontal Marcellus wells either completing or waiting on completion.

Antero has 169,000 net acres in the Marcellus Shale play of which only 8% was classified as proved at year-end 2010.

Woodford Shale

Antero is operating one drilling rig in the Arkoma Basin Woodford Shale play. Antero has 60 MMcfd of gross operated production from 124 wells online and 64 MMcfed of net production including non-operated production. The company's net non-operated production in the Arkoma is estimated to be 30 MMcfed. Antero has five non-operated wells drilling with a combined 75% working interest on our Arkoma acreage. Antero has one horizontal well waiting on completion.

Antero has an existing gas processing agreement in the Woodford Shale under which a portion of the company's operated and non-operated gas production is processed. Antero estimates that 9% of its year end 2010 Woodford Shale proved reserves are liquids, primarily comprised of NGLs. Antero has 71,000 net acres in the Arkoma Woodford Shale play.

Piceance Basin

Antero has one operated drilling rig running in the Piceance Basin. Our gross operated production in the Piceance is currently 35 MMcfd (28 MMcfed net including 1 MMcfed of non-operated production) from 168 wells online. Antero has 13 vertical Mesaverde wells waiting on completion in its Rifle rich gas area.

Antero recently entered into a long-term gas processing agreement with a third party midstream company in the Piceance Basin allowing it to realize a processing margin on its Piceance gas production effective January 1, 2011. Antero believes that virtually all of its Piceance Mesaverde gas production is liquids-rich gas that can be processed under current market conditions. Antero estimates that over 35% of its year end 2010 Piceance proved reserves are liquids, primarily comprised of NGLs. Antero has 68,000 net acres in the Piceance.

Fayetteville Shale

Antero has three non-operated Fayetteville Shale wells drilling with a combined 1% working interest. The company has 8 MMcfd of net production and 5,600 net acres in the Fayetteville Shale play.
