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-...
The ESeal Flex expandable system is an expandable solution primarily designed for well completions, stimulations, and workovers.
In cased-hole environments, ESeal Liner systems provide a solution to mitigate troubled casing intervals in onshore and offshore applications.
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...
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 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.
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.
