About Union Drilling    Who We Are, What We Do

Union Drilling, Inc. (“Union Drilling,” “Company” or “we”) provides contract land drilling services and equipment to oil and natural gas producers. We presently focus our operations in selected U.S. shale formations, with high growth potential, low finding and development costs and adequate take away capacity. Our principal operations are in the Appalachian Basin, extending from New York to Tennessee including the Marcellus, Huron, and Utica shales, as well as the Clinton, Medina, and Oriksany sands; the Arkoma Basin in eastern Oklahoma and Arkansas, including the Fayetteville, Caney, and Woodford shales; and the Fort Worth Basin in North Texas, including the Barnett Shale and in West Texas, the Permian and Delaware Basins. As our rigs are mobile, we are capable of moving them from one region to another in response to market conditions. In addition to our drilling rigs, we provide the drilling crews and most of the ancillary equipment needed to operate our drilling rigs. We do not invest in oil and natural gas properties.

We commenced operations in 1997 with 12 drilling rigs and related equipment acquired from an entity providing contract drilling services under the name “Union Drilling.” Through a combination of acquisitions and new rig construction, we have increased the size of our fleet to 51 marketed land drilling rigs. We continue to enhance our fleet of drilling rigs with technological capabilities through upgrades, acquisitions or new rig construction in order to improve drilling productivity and reduce total well costs for our customers. At various times, we remove rigs from our marketed fleet, and the components are made available for use on other rigs or sold.
