10. Segments and Geographic Area Analysis

     Although we provide contract drilling services with different types of offshore drilling rigs and also provide such services in many geographic locations, we have aggregated these operations into one reportable segment based on the similarity of economic characteristics among all divisions and locations, including the nature of services provided and the type of customers of such services, in accordance with FASB Accounting Standards Codification Topic 280, Segment Reporting.

     Revenues from contract drilling services by equipment-type are listed below:
