Successful development of titanium-drillpipe assemblies for short-radius drilling included appropriate conditioning of the outer-diameter (OD) and inner-diameter (ID) pipe-body surfaces to maximize fatigue life, optimizing the pipe-end upsetting procedure, establishing the tool-joint-to-pipe attachment method, and designing and testing a high-integrity tool joint and tool-joint-to-pipe connection for optimum fatigue performance. The full-length paper provides an overview of these developments and the laboratory-test results used to establish critical performance behavior and requirements for 2.875-in.-OD titanium drillpipe for short-radius drilling.
