For years, the reduction of tubular inside diameter (ID), or “telescoping effect,” limited the exploration and production of oil and gas. Using conventional technology, operators faced significant loss of ID in the course of the normal drilling process, during reentry and deepening of existing...
Implement an ESeal solution that would enable targeted completion with packer seats while also repairing the damaged vertical section of casing in the Barnett.
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.
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.
