ERODING WITH wellANT
Stuck Plug? Collapsed Tubulars? Downhole Obstructions?
Whether during production or in the decommissioning phase – problem wells are a recurring challenge. From stuck plugs and collapsed tubulars to cement remnants and damaged valves, such obstacles lead to costly downtime and technical complications.
This is where wellANT comes in.
Developed by ANT AG, wellANT is a next-generation erosion tool based on our proven Water Abrasive Suspension (WAS) technology. It enables the safe and precise removal of internal wellbore obstructions without mechanical force, heat, or swarf – preserving well integrity at all times.
Currently, wellANT is in advanced field testing and operates in shallow water depths via our Topside Drive System (TSDS) on various jointed pipe configurations. The design is modular, robust, and engineered to meet the evolving demands of plug & abandonment (P&A) and intervention.
