In order to facilitate a lower zone fracture treatment, three sets of perforations required a high-pressure, gas-tight isolation treatment that would maximize casing ID for completion tools. The solution provided a successful, gas-tight isolation of the three sets of perforations...
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-...
A leading onshore natural gas producer working Northern Louisiana experienced problems along the vertical section of a horizontal development well.
Enventure deployed two ESeal Liners enabling them to continue the planned completion.
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.
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 east coast Operator needed to cover and isolate two sets of perforations in the base casing. An ESeal Liner was chosen because three previous liners were performing successfully in the same area for this Operator. The perforations needed to be sealed so water influx could be stopped to...
A major operator in the Eagle Ford began a well recovery program to re-activate over 30 wells that stopped producing due to compromised well integrity (leaks).
