What is the most efficient method to cut tubing or casing on coiled tubing?
When cutting tubing using coiled tubing as a means of deployment, it is difficult to keep the knives of the cutting tool in a fixed position, because the coiled tubing is moving when the pumps are started or when the pump rate is increased. Using Baker Oil Tools’ robust, self-stabilizing DB™ Cutter and a Navi-Drill™ V.I.P. or X-treme™ workover motor in combination with the hydraulic/mechanical tubing anchor constitutes the preferred bottomhole assembly (BHA) method for this application. The anchor is a special design that eliminates coiled tubing movement during cutting operations. Both hydraulics and set-down weight are needed to operate the tool. A pre-determined flow rate is used to activate it. The grapple extends until it meets resistance from thetubing wall. Set-down weight locks the anchor against the casing wall. Using specially designed Baker Oil Tools DB Cutter knives, the maximum expansion is limited. Therefore, the tubing can be safely cut without the knives of the cutting
