The Flopetrol* Wireline Cutter is run down under its own weight guided by the line and when it strikes the stuck tool, it cuts the wire and wedges it into its body. Subsequently the cutter will be retrieved along with the cut wire. When the cutter strikes the rope socket of the stuck tool, the shock provided by the inertia of the hammer causes a shear pin to shear and the knife then rotates, cutting the wire. The rotation of the knife also pushes up a tapered key, wedging the wire into the cutter’s body. The Flopetrol wireline cutter is supplied in two models, one being designed for use with slicklines, the other for use with stranded lines. Both models can be supplied in two versions. The standard version is the one normally used, but if there is any risk of cutting the wireline at an interface, the interface version using a ‘go devil’ is preferred. The hammer section of the standard cutter is used as the ‘go devil’ on the interface version. The Flopetrol cable cutter has the following advantages: • no risk of accidental cutting at an interface • will not cut against the tubing • a clean cut by shearing is obtained even with regular use over a long period, due to the special knife shape • wire is cut short near to the rope socket: 1 inch (25 mm) for the slickine model, 2 inches for the stranded line model • cutting force is provided by the cutter’s own momentum rather than an outside energy supply • wire cutting and retrieval and cutter fishing are carried out in one operation Slickline - M-802709 Stranded Line - M-802721 (See charts overleaf) Wireline Operations - Fishing Tools Flopetrol - Rotary Wireline Cutters WIRELINE OPERATIONS: FISHING TOOLS * Denotes the mark of Schlumberger When the cutter strikes the rope socket of the stuck tool, the shock provided by the inertia of the hammer causes a shear pin to shear and the knife then rotates, cutting the wire.

• wire is cut short near to the rope socket: 1 inch (25 mm) for the slickine model, 2 inches for the stranded line model
• cutting force is provided by the cutter’s own momentum rather than an outside energy supply
• wire cutting and retrieval and cutter fishing are carried out in one operation
