Get back on planned drilling program and finish the well with an adequate hole size to evaluate potential production zones at TD.
Install a high-collapse SET® expandable liner to case off the trouble zone.
Accurately install SET® Openhole Clad solid expandable systems featuring water-sensitive swelling elastomer seals. The installation further proved SET® technology applied for the first time a year earlier in another field.
Install a 7-5/8 x 9-5/8 in. SET Openhole Liner (OHL) to isolate higher pressure zones so that mud weight could be reduced to combat lost circulation.
For years, the reduction of tubular inside diameter (ID), or “telescoping effect,” limited the exploration and production of oil and gas. Using conventional technology, operators faced significant loss of ID in the course of the normal drilling process, during reentry and deepening of existing...
During initial completion operations on a deepwater subsea oil well in the Gulf of Mexico, the 7-3/4 in., 46.1 lb/ft casing failed the pressure test in the production liner. Subsequent operations located the casing leak 1,800 ft above the target completion intervals. The original completion was...
