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 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.
An Operator in the Marcellus preparing a well for a primary frac operation discovered a long section of leaking connections in the vertical section of a horizontal well. In order to frac the well, the Operator needed a solution to restore wellbore pressure integrity that could...
