Isolate multiple zones while maximizing diameter by installing a SET Open-hole Liner with swellable elastomers. The maximum diameter would help reduce fluid friction during high-rate fracturing operations.
Implement an ESeal solution that would enable targeted completion with packer seats while also repairing the damaged vertical section of casing in the Barnett.
To completely isolate the main pay zone (MPZ) from lower residual oil zone (ROZ) with options to set conventional liner in future if needed for conformance work. Installation of 5-1/2” x 7”, 23 lb ESeal Liners to isolate the upper perforations in each well would enable injection through newly-...
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 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.
In cased-hole environments, ESeal Liner systems provide a solution to mitigate troubled casing intervals in onshore and offshore applications.
This casing failure occurred during the 13th stage of the well’s plug-&- perf frac job of it’s 4,500 ft lateral section. To avoid killing the well with potentially damaging weighted fluids, a rig assist snubbing unit was used to enable live-well operations including milling out the casing...
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.
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.
