In cased-hole environments, ESeal™ systems provide a solution for addressing troubled casing intervals in both onshore and offshore applications. From re-entry programs to remediating fields, Enventure offers an extensive array of applications and products designed to meet your objectives. Our suite of ESeal Intervention solutions include:
ESeal 3.0 Refrac Liners
ESeal High Performance Patch
ESEAL™ TECHNOLOGY SUITE Specifications
In cased-hole environments, ESeal™ Liner systems offer a larger diameter, making them a permanent and robust solid-steel casing reinforcement. They isolate perforations, repair damaged or corroded casing, or can be used as a large ID Refrac Liner to maximize power to the reservoir during hydraulic re-fracturing.

The ESeal™ Flex system is an expandable solution designed for completions, stimulations, and workovers. The system consists of expandable joints separated by conventional API tubulars. The expandable joints utilize bonded elastomeric seals that, once expanded, anchor the system and provide sealing capabilities for zonal isolation. Since the connections are not expanded, this allows for the use of premium connections such as the gas-tight Atlas Bradford® STI™.
ESeal™ Cased Hole systems provide a solution to mitigate troubled casing intervals. Elastomeric bands are attached to the top and bottom of the expandable liner that, when expanded, anchor the system to the base pipe. These elastomeric seals can also be placed at various intervals along the expandable liner in order to isolate specific zones.
Flex systems are typically used in cased-hole environments but can also be applied in openhole situations. Systems are readily available for casing off sections in most 4-1/2 in.
Common uses for ESeal™ Flex systems:
- Casing reinforcement and repair (leaks/splits, corrosion, perforations, packer seats, etc.)
- Water shut-off and control of production or injection
- Zonal isolation for stimulation of new perforations
ESeal™ Liner systems are most often installed to seal off perforations, damaged or corroded casing, or to reinforce casing. However, they have also been used in more novel applications such as expanded platforms for conventional packer installations and to reline entire wellbores. Operators have installed ESeal™ systems to control water, increase production, and reinforce casing. Because the burst strength of repaired well bores is frequently higher than that of the original casing, ESeal™ systems enable stimulation treatments, wellbore treatments, and hydraulic fracturing operations.
