  • Recent key advances in drillstring technology

    M. L. Payne, B. Chandler, M. J. Jellison, J. Shepard

    New developments in drilling tubulars are enabling continued advancements in drilling deeper, longer-reach wells more cost effectively. Field performance of the relatively new 5-7/8-in. drill pipe is presented. Since late 1999, more than 58 strings of 5-7/8 in. have been manufactured and successfully used to drill ERD, deepwater and ultra-deep HPHT wells in the South China Sea, Gulf of Mexico (GOM), Caspian Sea, offshore Trinidad, Wyoming and onshore Columbia.
