Segment Reporting [Abstract] |
Business Segments | 14. Business Segments The Company’s revenues, operating profits and identifiable assets are primarily attributable to three business segments: (i) contract drilling of oil and natural gas wells, (ii) pressure pumping services and (iii) the investment, on a non-operating working interest basis, in oil and natural gas properties. Each of these segments represents a distinct type of business. These segments have separate management teams which report to the Company’s chief operating decision maker. The results of operations in these segments are regularly reviewed by the chief operating decision maker for purposes of determining resource allocation and assessing performance. Contract Drilling — The Company markets its contract drilling services to major and independent oil and natural gas operators. As of December 31, 2014, the Company had 239 land-based drilling rigs in the continental United States, and western and northern Canada. For the years ended December 31, 2014, 2013 and, 2012, contract drilling revenue earned in Canada was $87.5 million, $86.6 million and $79.4 million, respectively. Additionally, long-lived assets within the contract drilling segment located in Canada totaled $57.6 million and $69.1 million as of December 31, 2014 and 2013, respectively. Pressure Pumping — The Company provides pressure pumping services to oil and natural gas operators primarily in Texas and the Appalachian region. Pressure pumping services are primarily well stimulation services (such as hydraulic fracturing) and cementing services for the completion of new wells and remedial work on existing wells. Well stimulation involves processes inside a well designed to enhance the flow of oil, natural gas, or other desired substances from the well. Cementing is the process of inserting material between the hole and the pipe to center and stabilize the pipe in the hole. Oil and Natural Gas — The Company owns and invests in oil and natural gas assets as a non-operating working interest owner. The Company’s oil and natural gas interests are located primarily in Texas and New Mexico. Major Customer — No single customer accounted for 10% or more of consolidated operating revenue in 2014. During 2013, one customer accounted for approximately $286 million or 10.5% of the Company’s consolidated operating revenues. These revenues were earned in both the Company’s contract drilling and pressure pumping businesses. No single customer accounted for 10% or more of consolidated operating revenues in 2012. The following tables summarize selected financial information relating to the Company’s business segments (in thousands):
