CNX Gas Corp.’s first horizontal well in the Marcellus Shale is producing at a rate of 6.5 MMcf/d, which sets a company record for daily output. The production rate is among the highest reported to date by any producer operating in the Appalachian Basin play. The CNX well, located in Green County, PA, began flowing on Oct. 2 at an initial rate of 1.2 MMcf/d and 4,000 pounds/square inch (psi) of backpressure. The backpressure gradually was reduced, which allowed daily production to increase to about 4 MMcf/d until early in December, when newly installed surface equipment enabled the well to flow at the record rate. The backpressure was being held at 2,640 psi. Cumulative production from the well prior to the record rate achieved was 106 MMcf. The Marcellus well was drilled to a vertical depth of 8,140 feet in the Huntersville Chert, penetrating 83 vertical feet of shale. CNX holds a 100% working stake in the well and also has 100% net revenue interest. The Pittsburgh-based independent is drilling its second vertical Marcellus Shale well, which would be hydraulically fractured using second and third horizontal wells.
