Operational Advantages of 5 7/8" XR® Drill Pipe:
Hydraulic Performance - 5 7/8" drill pipe provides enhanced hydraulic performance compared to 5 1/2" drill pipe for ERD and ultra-deep well applications.
Streamline Configuration - 5 7/8" drill pipe utilizes a 7" OD XT Tool joint allowing it to be used to drill inside 9 5/8" casing and 8 1/2" open-hole sections. Overshot fishing capability in an 8 1/2" hole is maintained.
Logistics - Eliminates the need for 6 5/8" drill pipe. 6 5/8" drill pipe is difficult to handle and can sacrifice rig space and setback capacity because it cannot be used to drill 8 1/2" hole sections.
Rig Modifications - 5 7/8" drill pipe minimizes rig modifications compared to 6 5/8" drill pipe.
