The following operational updates about Rex Energy Corporation’s Marcellus drilling activity thus far in 2010, from a company press release:

Butler County, Pennsylvania Marcellus Project Area

Drilling and completion activity in Rex Energy’s Marcellus Shale project area in Butler County, Pennsylvania is continuing to progress on schedule. The two ‘Magill’ horizontal wells completed by the company earlier this year have been flow-testing for approximately 20 days. The combined peak 24 hour rate of the two Magill wells to date has been 5.9 MMcfe per day. The company expects these rates to continue to rise as additional water is returned to the surface. The company’s refrigeration processing plant, and therefore its gas sales in Butler County, Pennsylvania, is currently shut-in for pipeline maintenance. The company expects the plant and sales to resume during May 2010 and to connect the Magill wells to the plant at that time.

[Rex Energy President & CEO Benjamin] Hulburt remarked, “When we compare the initial flow rates of the Magill wells to our P. Knauff #1H well, our first horizontal Marcellus Shale well completed in Butler County, Pennsylvania during 2009, we are very encouraged by the results. The P. Knauff #1H well took approximately 90 days to achieve its peak rate, and thereafter, the rate remained relatively flat for the next 180 days. Although the results of the Magill wells are still preliminary, we are encouraged by what appears to be a similar profile.”
