Abstract
In a method for releasing cables (2) from an attached well tool, where the cutting and the time for cutting can be decided from the surface above the well, and where a cable cutter (6) is arranged between the main part of a cable and a well tool, the cable cutter being controlled by an electronic timer, it is suggested that at least three parameters are used for controlling the cutter, e.g. a pulling force exerted by the cable on the well tool, the pressure in the well location, and time.
