Shaping the future together
ERODING WITH wellANT
Erosion tools for rigless P&A and production enhancement
High efficiency in rigless plug and abandonment as well as production enhancement is ensured by ANT’s erosion tool wellANT which is based on the Water Abrasive Suspension (WAS) erosion technology.
Fields of application
- Erosion of restrictions and collapsed wells
- Swarfless section eroding for abandonment plugs
- Erosion for side tracking
- Rigless solution
- Deployed on standard coiled tubing
- Small/micro cuttings
- Screening and analysis of returns
- Monitoring and control of eroding process
- Reuse of more than 80 % of abrasive
- Control and feedback
- High flexibility
- Time savings
- Cost reduction
- Maximum safety
wellANT examples of use
Collapsed and restricted wells
Restricted well access due to stuck objects, solids deposition or pipe deformations can cause extended non-productive times of associated assets as well as premature abandonment and challenging plugging.
Traditional pipe conveyed mechanical mills can suffer from unintended side tracking due to reactive torque from the deformation, and require expensive rig mobilisations.
In contrast, wellANT can be deployed on standard coiled tubing even from a Riserless Light Well Intervention (RLWI) vessel. A refined jet orientation ensures that the wellANT only erodes within the diameter of the existing wellbore, with very low reactive torque.
wellANT is also capable of 360-degree swarfless section eroding, which provides a fast and cost effective alternative to section milling.
As the tool erodes casing and concrete together, its consistent water jets will also erode through any other obstructions encountered, perfectly preparing a window for rock-to-rock T plugs.
wellANT also be used to complement coiled tubing drilling assemblies in side-tracking. Utilising the consistency of abrasive jet eroding, the tool can be deflected via cement plug, whipstock or open hole whipstock, to provide a clear pilot hole through multiple materials.
