Abstract:
A shifting tool is run on slickline and has an on board power supply. Rotary motion of the motor is converted to linear motion of the shifting tool using a ball screw device. The grip is obtained with longitudinal motion of a grip linkage and an on board jar then can do the shifting. Alternatively a linear motor can be used to extend and retract the grip assembly and shift using the jar tool. Optionally the tool can be anchored and linear motion from the on board power source operating a motor can do the shifting.
