Well Cutter®
Efficient and safe tubular cutting
Efficient, safe drill pipe, liner, tubing and casing recovery operations without the need for explosives.
The Well Cutter uses a rotating head to remove pipe incrementally, which prevents the creation of shavings. Due to the smooth, bevelled surface it produces, a polishing trip with drill pipe may be eliminated for increased operational efficiency.
A key benefit of the Well Cutter is that it eliminates the use of explosives which can pose an operational risk, especially when simultaneous operations are being conducted. The transfer of explosives may also cause complex logistics and significant operational delays, making the Well Cutter an attractive alternative for pipe recovery operations. Conveyed on e-line for accurate depth control, the Well Cutter incorporates a ‘fail-safe’ mechanism that prevents the tool from getting stuck.

The Well Cutter enables efficient and safe tubular cutting for pipe recovery or completion removal without the use of explosives. Utilizing a fast, grinding technique rather than a blade, the Well Cutter produces a smooth, polished surface.
This precludes the need for a polishing trip to dress the cut, resulting in significant rig time savings. It can be run slick, on e-line or equipped with a ‘no-go’ for a precise cut at depth. And it can be deployed independently or combined with the Well Tractor® for cuts in highly deviated or horizontal wells.
