Large-diameter completion string saves time on landing and intervention operations (World Oil Magazine, 2017)
Early subsea wells used API drill pipe, which was available on the rig, to land production tubing and completion equipment from the surface vessel to the subsea wellhead. As total depths approached 30,000 ft, pressures increased beyond the capacity of standard API drill pipe and rotary-shouldered connections with gas-tight, metal-to-metal seals. This led to the development of dedicated completion tubulars, starting in the early 2000s, but further improvements were still possible.
