Perforation Shutoff Patches

Deployable via rig or wireline

Whether you’re trying to proactively modify your production profile or work to prevent the sudden and unexpected ingress of water, shutting off unproductive perforations is often the only way to maintain the productivity of a problem well.

But perforation shutoff brings its own headaches. Traditional solutions often shrink the ID of your well bore, restricting access and complicating any future work that needs to be carried out in the well below.

Run-of-the-mill shutoff solutions are also fairly indiscriminate; making it difficult to seal a problematic perforation without accidentally blocking other - productive - perforations in the same zone or cluster; reducing your flow rate and diminishing the overall productivity of your well.

Then there’s the expense involved in deploying patches, packers and plugs, straddles or gel shutoff solutions: The overwhelming majority of readily-available technologies require rig time to deploy, as well as support from highly-trained staff and a significant upfront investment that you may not be able to recoup for several weeks.

In short, plugging or sealing unwanted perforations is still a major source of frustration for oil and gas operators across the globe - and a major contributor to unnecessary downtime.

Building A Better Class Of Perforation Shutoff Patches

Technologies To Suit The Needs Of Modern Oil And Gas Operations

That’s why our team of highly-skilled engineers have designed a range of compact perforation shutoff patches that are capable of isolating problem zones in record time.

Deployable by wireline, workover rig, drilling rig or snubbing unit, these cutting-edge devices create a pressure- and water-resistant seal that’s designed to stand the test of time; restoring integrity for the full lifespan of your well.

Products like OnePatch and Reline MNS are also designed to:

Deploy and activate in one trip, without the help of balls, darts or inflatables – saving rig time and money
Preserve the internal diameter of cased or uncased bore; allowing you to run tools or carry out future remediation work further down the well
Allow for pinpoint accuracy; enabling you to effectively seal off water, gas or sand producing perforations without unnecessarily diminishing the overall productivity of a specific zone
Produce an effective and dependable seal in corroded, ovalized or leaky casing

Most of our perforation shutoff patches can also be deployed through ID restricting components like frac sleeves. Above all, the focus is on providing efficient and reliable isolation that lets you safeguard productive wells against the ingress of water, sand or gas.

Adaptable Perforation Shutoff Patches

Designed To Optimize The Performance Of Your Well

While production profiles may remain static for a couple of years at a time, most wells are a living environment and there’s often a need to reposition perforations as the well matures; tapping into new zones and allowing you to maintain productivity.

We understand that perforation shutoff technologies designed to meet this use-case have to be affordable and leave the well-bore unrestricted so that you can continue working downhole of the interval in question. Shutoff solutions designed for routine work also need to be easy to deploy, so that you can schedule workovers as and when it’s convenient for your team.

But we also recognize that there are times when speed is of the essence: thief zones, water-producing features and gas pockets have a habit of cropping up out of nowhere and many operators also need perforation shutoff technologies that can be deployed in one trip - with or without a rig.
