Abstract
This invention relates to a method for activating and deactivating a GS-tool () having grippers (), tool housing (), spindle (), and main spring () arranged to pre-tension the gripper () towards a deactivated position as the GS-tool () is displaceable in a wellbore () in the ground. The method includes the steps of coupling the spindle () of the GS-tool () to an actuator mandrel () of an actuator (); arranging an activating sleeve between the tool housing () and an actuator housing (); and displacing the actuator mandrel () and thereby the spindle () relative to the tool housing () in a direction from the GS-tool () until the grippers () have reached activated positions by overcoming the force from the main spring (). A GS-tool for implementing the method is also described.
