Corporate Profile

We provide contract land drilling services to oil and natural gas exploration and production companies. As of December 31, 2006, we owned a fleet of 65 land drilling rigs, of which 52 were operating, three were in the process of being refurbished and ten were held in inventory. As of December 31, 2006, we also owned a fleet of approximately 66 trucks used to transport our rigs. On January 9, 2007, we acquired 31 workover rigs through our acquisition of Eagle Well Service, Inc.  Twenty-four of these rigs were in service at the time of the acquisition, and we intend to deploy the remaining seven rigs on a periodic basis with the expectation that all 31 rigs will be operating by July 2007. Seventeen of the acquired workover rigs are less than two years old.

We commenced operations in 2001 with the purchase of one stacked 650-horsepower rig that we refurbished and deployed. We subsequently made selective acquisitions of both operational and inventoried rigs, as well as ancillary equipment. Our management team has significant experience not only with acquiring rigs, but also with refurbishing and deploying inventoried rigs. We have successfully refurbished and brought into operation 22 inventoried drilling rigs during the period from November 2003 through December 2006. Upon completion of refurbishment, the rigs either met or exceeded our operating expectations. In addition, we have a 41,000 square foot machine shop in Oklahoma City, which allows us to refurbish and repair our rigs and equipment in-house. This facility, which complements our four rig refurbishment yards, significantly reduces our reliance on outside machine shops and the attendant risk of third-party delays in our rig refurbishment program.

As of December 31, 2006, we were operating our drillings rigs in Oklahoma, Kansas, the Barnett Shale and Cotton Valley trends and Palo Duro Basin in Texas, the Williston Basin in North Dakota and the Piceance Basin in Colorado. Our workover rigs are currently operating in Oklahoma, Texas, Kansas and New Mexico.

A majority of the wells we have drilled for our customers have been drilled in search of natural gas reserves. Natural gas is often found in deep and complex geologic formations that generally require higher horsepower, premium rigs and experienced crews to reach targeted depths. Our fleet of 65 drilling rigs includes 38 rigs ranging from 950 to 2,500 horsepower. Accordingly, such rigs can, or in the case of inventoried rigs upon refurbishment will be able to, reach the depths required to explore for deep natural gas reserves. Our higher horsepower rigs can also drill horizontal wells, which are increasing as a percentage of total wells drilled in North America. We believe our premium rig fleet, rig inventory and experienced crews position us to benefit from the strong natural gas drilling activity in our core operating areas.
