Penn Virginia Corporation Announces Horizontal Drilling Success in East Texas

RADNOR, Pa.--

Penn Virginia Corporation (NYSE:PVA) today announced horizontal drilling success with its Lower Bossier (Haynesville) Shale test well in Harrison County, Texas.

PVA successfully completed the Fogle #5-H (100 percent working interest), which is PVA's first horizontal test well exclusively targeting the Bossier (Haynesville) Shale formation in east Texas. The well had an initial production rate of approximately 8.0 million cubic feet of natural gas (MMcf) per day with a flowing casing pressure of approximately 5,000 lbs. The well reached a total vertical depth of 11,378 feet with a 3,861-foot lateral in the Bossier formation. The well is connected to existing infrastructure and sales have been limited to approximately 5.0 MMcf per day with a flowing casing pressure of approximately 6,000 lbs due to pipeline capacity constraints. Upon the availability of additional takeaway capacity which is anticipated by July, PVA expects the well to produce at an initial rate of between 10 and 15 MMcf per day.

As previously announced, PVA drilled and completed 17 vertical test wells across its approximate 53,000-acre leasehold, testing a combination of four different reservoirs below the Cotton Valley including the Upper Bossier Shale and the Lower Bossier Shale, which corresponds to the Haynesville Shale, referred to by other operators in recent public announcements. Based on the positive results of these vertical tests and this successful horizontal test well, PVA now expects to drill at least five (5.0 net) additional horizontal Bossier Shale wells in 2008.

Management Comment

A. James Dearlove, President and Chief Executive Officer of PVA, said, "We are very encouraged by the initial results of the Fogle #5-H test well, which exceeded our expectations. Looking forward, we have an acreage position of approximately 53,000 net acres in east Texas, much of which is expected to be prospective in the Bossier Shale. The additional wells we plan to drill during the remainder of 2008 should provide valuable information with respect to defining the full potential of this resource. We will continue to pursue opportunities to expand our acreage holdings in this part of east Texas, as well as our ongoing 20-acre spaced development efforts in the associated Cotton Valley play."
