Perforations shut off

Scroll Indication »

Saltel Industries offers a remedial solution for perforations shut off using a thin walled expandable steel patch run on drill pipe or smart coiled tubing, that allows access to the well below (for packers, tubing anchors….) Saltel expandable steel Patch seals effectively and holds significant differential pressures.

A top-notch inner-lining for perforation shut off.

Saltel offers a solution for perforation shut off. A thin-walled casing patch allows large ID access to the well below, for example, to install packers or tubing anchors. The patch is conveyable with a drilling rig, a workover rig, a snubbing unit, or an intelligent coiled tubing unit. It seals effectively and holds significant differential pressures.

Saltel Patch can be set to seal perforations to eliminate or reduces water production without significantly restricting the wellbore access. It seals the perforated zone without restricting the production from the neighboring perforations. It provides an effective seal even in damaged or worn casings.

Saltel Patch can be used to isolate a zone producing unwanted gas or fluids. Likewise, as with all Saltel patches, you can make sure to get the minimal loss of internal diameter. At the same time, you will ensure an effective seal, even in non-uniform casings.

Actually many conventional wells are completed and perforated in both production and injection wells. The required profile for a well will change over time as fluid levels and production techniques change. It may become necessary to close off existing perforations, perforate in different zones, or modify injection profiles.

Challenges

■ Firstly, ensure the accurate positioning close to oil or gas-producing perforations.

■ Secondly, achieve an effective seal even in corroded or ovalized holes.

■ Thirdly, ensure maximum internal diameter to leave full access to the perforation tool.

■ Benefit from fast delivery.

■ Then, get an effective, pressure-resistant, and watertight sealing.

Benefits

■ Restores casing integrity, holding internal differentials 15,000 psi

■ Quick, efficient, and reliable isolation

■ Large ID. Leaves access for running tools or drilling ahead

■ Repairs completion modules (ICDs, sand screens, frac ports…)

■ Always seals, regardless of casing condition. The Saltel Expandable Steel Patch is a perfect way to seal oval-shaped casings and miscellaneous completion equipment profiles. The inflatable setting element makes it easy to create a perfect seal every time.
