Coretrax Inner Core - OnePatch

Our OnePatch is a rig ready solution to isolate various casing integrity issues. Its compact design and simple operation enable repairs to be made efficiently, significantly reducing operational expenditure.

The tool can seal perforations or repair leaking casing while providing a large
production conduit to bring the well back online. The device can be snubbed on a
live well so there is no requirement to cease production before deployment.
With its robust construction, it is designed to last the life of the well.
