Annulus Isolation
Isolate the annulus to prevent water influx, stop water production, and enhance oil and gas recovery, extending the life of your well.
CannSeal Epoxy Injection for Annulus Isolation
Interwell’s CannSeal epoxy injection technology offers a precise, durable solution for isolating the annulus in well intervention operations. Designed to prevent water influx, mitigate sustained casing pressure, and increase oil and gas production, this solution is applicable even in horizontal wells. The epoxy solidifies under well temperature conditions, sealing perforations and providing a remedial integrity barrier without the need for traditional patching.
With the ability to inject into a cement matrix for micro-annulus repair, achieving a pumping differential pressure of 200 bar, CannSeal extends the lifespan of wells and improves recovery rates. The epoxy does not slump or segregate, making it highly effective across various well geometries. It’s run on standard electric wireline and placed precisely to create an annular seal in a single run, ensuring operational efficiency and cost savings.
This technology is ideally suited for isolating the annular space between sand screens or uncemented liners, or in oil-producing wells with sand screens, with or without gravel packs.
Restore Well Integrity, Reduce Water Production
CannSeal epoxy technology provides a cost-effective, time-efficient solution for reducing water production while restoring well integrity. By targeting sustained casing pressure or placing a remedial integrity barrier, CannSeal helps to re-establish well control and unlock potential revenue streams.
Whether isolating the annular space or sealing off a leaking production packer, this advanced epoxy sealant is tailored to each specific application, solidifying under well conditions without slumping or segregation. Applicable in both vertical and horizontal wells, it’s an ideal solution for extending the operational life of your well while maximizing oil and gas production.
