Patent ID: 10018006

Abstract:
This invention relates to a method for activating and deactivating a GS-tool (2) having grippers (22), tool housing (32), spindle (22), and main spring (50) arranged to pre-tension the gripper (44) towards a deactivated position as the GS-tool (2) is displaceable in a wellbore (10) in the ground. The method includes the steps of coupling the spindle (22) of the GS-tool (2) to an actuator mandrel (12) of an actuator (4); arranging an activating sleeve between the tool housing (32) and an actuator housing (14); and displacing the actuator mandrel (12) and thereby the spindle (22) relative to the tool housing (32) in a direction from the GS-tool (2) until the grippers (44) have reached activated positions by overcoming the force from the main spring (5). A GS-tool for implementing the method is also described.
