Definitions
- the second casing is very often stuck in settled baryte or other sediments, or cement. Friction onto the work stiring, e.g.
- a drill pipe string in the well along the entire length of the first tubing, all the way from the surface and down to the spear in the top of the second casing, may be large and much force is lost along the work string path. Thus one may not pull loose a cut-off length of the second casing more than a few metres.
- Such cutting tools and spears used are normally controlled by balls which take up to several hours to circulate in to land in a seat in each tool to be used, and the tools may be pressure and / or pull actuated.
- Fig. 1 is an overview of the well context and an overview of the toolstring.
- Fig. 2 is an overview of the toolstring after a cut has been made at the target depth.
- valve tool is closed, the spear is pressure initiated, pull on the work string sets the spear, and held. The valve is then opened.
- valve tool With the valve tool open, flow goes to the cutter tool which is actuated to extend the knvies and cut at target depth .
- the tension-vulnerable valve tool is arranged below the spear.
