World Record: 1,180-ton tubular string run to total depth in Gulf of Mexico

Weatherford achieved a new world record by landing a 1,180-ton casing string at a total depth of 26,805 ft. The job was performed on a deepwater rig in the GOM this fall.

Weatherford achieved a new world record by landing a 1,180-ton (2,360,700-lb) casing string at a total depth of 26,805 ft (8,170 m). The job was performed on a deepwater rig in the Gulf of Mexico this fall.

The operator of a deepwater rig in the Green Canyon required installation of a heavy, 14-in., 112.6 lb/ft casing string. The total weight of the casing and landing string needed to reach total depth was 1,180 tons. The operator contracted with Weatherford to install the landing-string slips 1250 ("LSS 1250"), which acts as a spider to safely and efficiently grip tubulars and has a maximum load capacity of 1,250 tons (2,500,000 lb).

Weatherford deployed the LSS 1250 after providing an engineering analysis to verify that the pipe could reach total depth without damaging the tubulars from excess stress. The team then ran the string to total depth with no issues. Without the increased load capacity provided by the LSS 1250, the operator would have needed to drill a second hole section and run two separate casing strings at an approximate cost of $15 million.
