At AOG 2025, KAESO Energy Services will present BiSN’s wel-lok™ bismuth alloy plug technology—an innovative, rigless solution for well integrity and permanent abandonment. This technology creates a gas-tight, metal-to-metal seal using a bismuth-based alloy, ideal for complex well conditions such as damaged casings, sand screens, and gravel packs.

Successfully deployed in Angola for water shut-off in challenging wells, the wel-lok™ tool has increased oil production and reduced the need for costly remedial operations. The presentation will target oil & gas operators, engineers, and technical decision-makers, showcasing how this technology enhances well integrity, reduces operational costs, and supports environmentally responsible operations.

This technology addresses several critical challenges faced by operators, including the inability to apply traditional plugs in wells with complex geometries or completion types, rising intervention costs, and the growing pressure to adopt cleaner, more efficient abandonment solutions. By providing a permanent seal without requiring a rig, the wel-lok™ tool offers a safer, faster, and more economical alternative for well isolation, water shut-off, and field abandonment operations.
