This total acreage position is largely contiguous and is located in Sullivan, Knox, Greene, Owen, Clay and Lawrence counties of southwestern Indiana. The acreage is within the northern "biogenic" part of the New Albany Shale play where several operators have drilled over 40 successful horizontal wells.

"We have been studying the New Albany Shale for over two years and believe the predictable and statistical nature of its development is a perfect fit for our investment programs," stated Richard D. Weber, President and Chief Operating Officer of Atlas Energy. "This acreage provides Atlas with approximately 800 horizontal drilling locations, which will support a large scale drilling program for many years."

Development of the New Albany Shale will be overseen by Company's Antrim Shale operating team, led by Dick Redmond, President of Atlas Energy Michigan, LLC. The New Albany Shale has many similarities to Michigan's biogenic Antrim Shale where Atlas Energy is the largest and one of the lowest cost operators. "Our team has proven to be one of the leading operators of biogenic shale gas," stated Mr. Redmond. "We have pioneered numerous drilling, completion and operating techniques and are excited about bringing this expertise to the emerging New Albany Shale."

Biogenic shale is unique in that methane is created as a bi-product of bacterial consumption of organic material contained in the shale. The Devonian aged New Albany Shale is a blanket formation found at depths of 500 to 3,000 feet, with thicknesses ranging from 100 to 200 feet. However, unlike the Antrim Shale, where natural fracture patterns are low angle, the natural fracture patterns in the New Albany Shale are vertically oriented. Atlas has reviewed over thirty successful horizontal completions within and in close proximity to the acreage where it has acquired rights and has observed an average estimated ultimate recovery of approximately 1.3 Bcf per well. Horizontal wells in the New Albany Shale having 4,000 to 5,000 foot laterals can be drilled and completed for approximately $1.3 million.
