TECHNOLOGY STATUS ASSESSMENT For Project DE-FC26-NT42951 “Development and Application of Insulated Drill Pipe for High Temperature, High Pressure Drilling” Drill Cool Systems, Inc. 627 Williams Street Bakersfield, CA 93305 Overview The objective of this document is to provide a summary report describing the state-ofthe-art of the proposed technology. When we refer to “the proposed technology” of insulated drill pipe (IDP), however, we should remember that IDP addresses several effects of high-temperature drilling that are usually addressed with different technologies. This assessment, then, will look at several different kinds of HT drilling tools as they relate to the use of IDP.
