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.
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...
An Operator, in the Permian, discovered they did not obtain cement coverage along the entire length of the lateral after cementing their production casing.
A Major Mid-Continent Operator needed a solution that could cover four perforations that were prematurely shot in the heel of the horizontal Woodford Shale well. The ESeal HP Liner was successfully tested to 13,500 psi and passed 31 fracturing stages to re-establish the fracturing program.
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...
The ESeal Flex expandable system is an expandable solution primarily designed for well completions, stimulations, and workovers.
The ESeal Patch is a single-joint, solid steel, expandable casing patch for operators who need a permanent, inexpensive casing patch solution that reliably restores well integrity.
