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 had two sections of perforations in 4-1/2 in. casing that needed to be repaired. They required a solution that would repair the 4-1/2 in. casing and still maintain sufficient ID for this well to be used as a power water injector well.

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...

A major operator in the Eagle Ford began a well recovery program to re-activate over 30 wells that stopped producing due to compromised well integrity (leaks).

An Operator, in the Permian, discovered they did not obtain cement coverage along the entire length of the lateral after cementing their production casing.

A Major Mid-Continent Operator needed a solution that could cover four perforations that were prematurely shot in the heel of the horizontal Woodford Shale well.  The ESeal HP Liner was successfully tested to 13,500 psi and passed 31 fracturing stages to re-establish the fracturing program.

A major Operator in the Marcellus required a solution to seal squeeze perforations which would have to withstand high pressure frac operations. The area Regulatory Agency had suspended operations, not allowing completion of the well due to poor cement behind the production casing. The Operator...

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.
