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.
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.
