CUTTING TOOL

The Westerton electric cutting tool is designed to cut single strings of casing, tubing or drillpipe. The cutter features a single blade which is driven by a downhole electric motor for controlled, smooth efficient cutting. A real time surface read out monitors the cut and signals when the operation is complete. A unique six point anchoring system ensures that the cutter remains stationary during the cut out period.

Operation

The Westerton electric cutting tool is run on either mono conductor or seven strand Hepta Logging cable. After the surface operational checks are complete the tool is lowered on the electric cable to the cutting depth. Calibration of the depth can be confirmed using either a Passive CCL or the on board Active CCL. When the desired depth is obtained an electric current activates the anchoring system which locks the tool in place. The power is then fed to the cutting motor and the cut is initiated by the blade from the revolving nose cone. Constant monitoring on surface keeps the operator informed of blade position, rpm and feed rate. When the cut is complete the blade is retracted into the nose cone and the anchor system relaxes. Straight pick up is all that is required to recover the tool to surface.
