Jetstring sub designed to improve cleaning for downhole equipment
The durability of drill pipe-based completion workover risers lowers cost of ownership and can be run by drilling rig crews, giving operators the flexibility to move seamlessly between drilling and completion operations
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.
The 6 5/8-in. heavy wall, 150-ksi yield strength pipe incorporates an innovative thick-walled section in the slip contact area to resist slip crushing loads and a uniquely designed dual-diameter tool joint to increase elevator capacity.
Re-engineered system pushes the lifting limit to 2,000,000 pounds and beyond.
Workstrings, LLC, a subsidiary of Superior Energy Services, Inc., is proud to
announce that their new landing string system for running long heavy casing strings in the magnitude of 1.5 to 2.0 million lbs has successfully been run in the Gulf of Mexico.
