10/12/2008

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-...

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.

In the Marcellus Shale, fracturing rates and pressures can be substantial, but there are other problems also associated with completing these wells, which can promote casing failure or compromise the pressureintegrity of a well. A...

An Operator in the West Virginia Marcellus Shale required a cost-effective solution to seal off old perforations to enable high-pressure refrac operations.  The ESeal RF Liner was successfully installed in the horizontal wellbore and tested to 9,500 psi.

02/12/2009

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.

The ESeal Flex expandable system is an expandable solution primarily designed for well completions, stimulations, and workovers.
