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...

Results from two case histories in shale plays indicate that the use of an expandable refrac liner gives comparable, or better, gas production than other methods of perforation isolation, and provides assurance
for frac stage injectivity.

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.

A major operator in the Eagle Ford began a well recovery program to re-activate over 30 wells that stopped producing due to compromised well integrity (leaks).

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.

An Operator, in the Permian, discovered they did not obtain cement coverage along the entire length of the lateral after cementing their production casing.

A major Operator in the Barnett Shale needed to isolate four depleted perforation clusters to successfully refrac their well.  

The ESeal RF Liner increased flow area by 47%, compared to the conventional recompletion option.
