Marcellus Shale | Southwestern Energy

The Devonian-aged Marcellus Shale runs about 600 miles across Pennsylvania.

In 2008, Southwestern invested $58 million in the Marcellus Shale. In the first quarter of 2009, the company purchased approximately 21,715 net acres in Lycoming County, Pennsylvania, for approximately $8.2 million.
At June 30, 2010, Southwestern held approximately 150,800 net undeveloped acres in Pennsylvania under which it believes the Marcellus Shale is prospective. In July, the company placed the Greenzweig #1-H well, its first horizontal well which was drilled in 2008, on production and it is currently producing approximately 3.3 MMcf per day without compression into the pipeline with just over 3,000 psi of flowing tubing pressure. The Greenzweig #1-H well was drilled in late-2008 and had a 2,945-foot horizontal lateral and was fractured stimulated with slickwater in 7 stages. In 2010, the company has drilled 4 horizontal wells, all of which are currently being scheduled to be completed in September. Approximately 20 wells are expected to be drilled by Southwestern in 2010.
In 2010, the company plans to invest approximately $125 million in Appalachia, which includes drilling with one operated rig in the Marcellus Shale play in Pennsylvania and participating in a total of 30 to 35 wells, 20 of which will be operated.
