Schlumberger Data and Consulting Services was contracted by the United States Department of Energy, Office of Fossil Energy, National Energy Technology Laboratory to provide current drilling technology and cost benchmarks, thereby providing a base reference point from which current research and development can be better focused and future industry developments can be better recognized. This work included identifying locations, targeted reservoirs, and operators of wells with true vertical depths (TVD?s) greater than 15,000 feet deep in the U.S. drilled during the last 5-7 years, categorizing these wells by completion method, and determining representative type wells. Numerous operators were requested to provide information on drilling and completion, data monitoring and management, well control, and tubulars. Results of this information gathering effort have been tabulated and condensed in this final report.
