High Expansion Plug Systems

High Expansion Plug Systems are engineered to set a qualified well barrier across a far wider range of internal diameters than a conventional plug can cover. One tool handles casing transitions, drifted sections and unexpected restrictions, so a single trip replaces the several a fixed-size plug would need.

The plugs are designed for high differential pressure and are qualified against recognised barrier standards. The expansion mechanism seals metal to metal against the casing wall, which keeps performance predictable in wells where the internal profile is not exactly as drawn.

Typical applications include temporary isolation for workover and intervention, permanent abandonment barriers, isolation across casing transitions, and any operation where the exact restriction is unknown before the tool goes in the hole.
