Drilling operations are limited by the materials used to manufacture drill pipe. Composite Drill Pipe (CDP) is available, or under development which weighs one half or less than the equivalent, highest quality, steel drill pipe. Further, with CDP, it is possible to incorporate a signal transmission capability within the walls which will allow real time monitoring of down well conditions while drilling. The U.S. Department of Energy has recognized the need to bring this advanced technology to fruition and has joined with Advanced Composite Products and Technology Inc in a program to make CDP available to the drilling industry. This program has successfully placed “Short Radius” CDP in the field, is currently completing the development and testing of “Extended Reach/ Deep Water” CDP. In a continuing effort, both the capability for “Real Time” signal transmission and extending the physical/mechanical characteristics of the CDP to meet the rigorous conditions of Deep Trek operations, are under development. This paper presents an in depth review of the background and current status of these programs.
