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.

Accurately install SET® Openhole Clad solid expandable systems featuring water-sensitive swelling elastomer seals. The installation further proved SET® technology applied for the first time a year earlier in another field.

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.

As part of a multi-well program, isolate severe water-thief zones in a field where squeezing, casing patches and dual packer isolation assemblies rarely worked. The solution increased production and ultimately resulted in higher reserves.

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.

A major operator in the Middle East encountered significant corrosion in 7" base casing on one of its injection wells in an important onshore oil field. The corrosion of the pipe presented a safety risk, as well as, a commercial concern that well integrity would be jeopardized and reduce...
