Alloy Elements

isol8’s cold-set alloy elements retrofit to replace elastomeric seals. They set like elastomers but perform like metal, offering greater strength, higher temperature tolerance, and longer life. Fusion® hot-set bonded-alloy versions, enabled by proprietary intermetallic heaters, extend performance further. Suitable for oil and gas, geothermal, and carbon storage wells.

Alloy Barriers

Alloy Barriers are formed by melting a low-melting-point alloy with a specialised heater (electric and/or exothermic). Once liquefied, the alloy flows into position and solidifies, creating a robust, pressure-resistant seal. This technology delivers reliable barriers for annulus isolation, well integrity restoration, production enhancement, and plug-and-abandonment (P&A) operations.

Technology

isol8 is the industry leader in bismuth, bonded-bismuth and beyond-bismuth alloy sealing technology, combined with proprietary exothermic heater systems (thermite and intermetallic).

View Application

Alloy Element External Casing Packer (Well Construction)

A full bore ECP, set conventionally with a bonded alloy element to prevent surface casing pressure.

View Application

Alloy Barrier Section Milled Plug (P&A)

An alloy barrier in a section milled casing can provide a superior, gas tight seal for P&A and slot recovery applications

View Application

Alloy Barrier Single / Multi Annulus Isolation (P&A)

In larger diameter casings, an alloy barrier can be formed in multi-annuli through slots or perforations.

View Application

Alloy Barrier Straddle / Patch (Well Intervention)

Alloy straddle solutions can be engineered to maximise the ID through bore, deployed on a conventional GS setting tool, with two exothermic heaters attached below the setting tool.

View Application

Alloy Barrier Packer Repair (Well Intervention)

Packer integrity can be restored by deploying bismuth alloy beads down the annulus and forming a gas tight seal with a wireline deployed exothermic heater.

View Application

Alloy Element Packer (Well Completion)

Bonded alloy elements can be engineered to replace elastomers, for conventional O&G wells and are ideally suited for CO2 storage and geothermal well applications.
