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.
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.
Applying solid expandable technology in existing storage wells for sealing and repairing corroded or damaged casing allows for maintaining the largest internal diameter possible while ensuring sufficient throughput capacity. This is important in meeting...
