The Omega Non-Impact Wire Cutter is an electronic timer controlled wire cutter, which may be used in highly deviated wells to recover the maximum amount of wire from a stuck down-hole tool, prior to commencing fishing operations. The ReAct© cutter timer interval is controlled by fitting a special plug at the top of the actuator sub-assembly. Once fitted an LED on the plug flashes to confirm that the ReAct© timer has started the countdown. A suite of colour coded plugs is supplied, which automatically select pre-programmed countdown intervals.
The cutter is then fitted over the wire, installed in the lubricator and then dropped down-hole. Integral rollers allow the cutter to reach the maximum depth. After the ReAct© countdown, the actuator module is triggered, operating a hydrostatic/hydraulic piston arrangement which operates the mechanical cutter, simultaneously severing the wire and gripping the wire just above the cut. The wire pigtail above the stuck tool fishing neck is identical to that seen on simple impact type cutters.
The cutter is designed to be fully field redressable, with the actuator module replaced on site. If suitable workshop facilities are available, the actuator module may also be redressed, with only the ReAct© electronics sub-assembly returned to Omega for refurbishment.
