Objective

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.

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.

In the first stage of the fracturing program, the uppermost fracture sleeve failed - leaving the economic viability of the wells at risk.

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.

11/21/2013

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

11/01/2014

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.
