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-...

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...

We’ve expanded the Operating Envelope of Expandable Liners for Precise and Reliable Refracturing Applications

The newly enhanced ESeal RF and ESeal RFHT (High-Temp) Refrac Liners provide the industry’s highest strength and temperature ratings...

SET technology is the result of a cold-working process that permanently deforms the pipe without any additional heat. The procedure inherent to expanding tubulars takes the steel beyond its elastic limit into the plastic region of the stress-strain curve, while remaining safely below ultimate...

Matt Meiners, Enventure Global Technology, USA, explores how advancements in expandable liners are helping to improve zonal isolations when refracturing.

Recent shifts in the economics of oil and gas production have driven operators to focus more attention on enhanced production...

A major Operator in the Barnett Shale needed to isolate four depleted perforation clusters to successfully refrac their well.  

The ESeal RF Liner increased flow area by 47%, compared to the conventional recompletion option.
