Challenge: Design and implement a field-level remediation plan using cased-hole SET® Solid Expandable Tubular technology to facilitate production restoration.
ESeal™ HP Patch systems: A high-performance wellbore repair solution.
These systems utilize a higher yield-strength material than standard ESeal systems. The material’s increased burst and collapse ratings provide enhanced performance and reliability.
From re-completions to field...
Enventure's 4-1/4 x 5-1/2 inch, 17 lb/ft ESeal Liner was installed in a Barnett Shale 3000 ft lateral wellbore to isolate existing perforations while allowing fracturing of new shale colume between old perforation clusters.
The ESeal Flex expandable system is an expandable solution primarily designed for well completions, stimulations, and workovers.
The Operator utilized Enventure's ESeal Liner expandable technology to isolate zones and provide a high-pressure environment for an aggressive re-frac program. The treatments paid out in ~2 months and increased production 700% where cement squeezes failed.
As part of a multi-well program, isolate severe water-thief zones in a field where squeezing, casing patches and dual packer isolation assemblies rarely worked. The solution increased production and ultimately resulted in higher reserves.
In cased-hole environments, ESeal Liner systems provide a solution to mitigate troubled casing intervals in onshore and offshore applications.
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.
