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.
Section eroding
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.
Side tracking
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.
