Expandable-tubular technology involves a process that expands casing in oil wells drilled in especially challenging environments, such as deepwater. Until now, operators have had to use progressively smallerdiameter pipe as a well was drilled deeper; but expandable-tubular goods are designed for...

The Operator had two sections of perforations in 4-1/2 in. casing that needed to be repaired. They required a solution that would repair the 4-1/2 in. casing and still maintain sufficient ID for this well to be used as a power water injector well.

In the Marcellus Shale, fracturing rates and pressures can be substantial, but there are other problems also associated with completing these wells, which can promote casing failure or compromise the pressureintegrity of a well. A...

In the first stage of the fracturing program, the uppermost fracture sleeve failed - leaving the economic viability of the wells at risk.

An Operator, in the Ardmore Basin, was unable to put a well onto first production due to casing damage at a 5½” to 4½” casing crossover.

A major Operator in the Anadarko Basin of Oklahoma lost pressure integrity during completion / frac operation.  A 3-1/2" ESeal HP Liner straddled the parted packer, restoring pressure integrity, and enabling the Operator to continue their completion / frac operations
