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...

A major operator in the Middle East encountered significant corrosion in 7" base casing on one of its injection wells in an important onshore oil field. The corrosion of the pipe presented a safety risk, as well as, a commercial concern that well integrity would be jeopardized and reduce...

The ESeal Liner provided the maximum flow area for injector fluids resulting in greater injection volumes and rates due to less friction pressure loss during injection.  The standard conventional scab liner is the 5 in. liner which provides a 4.481 in. ID., while the 5½ x 7 in. ESeal liner...
