A drilling assembly for making a passage in an object within a petroleum well. The drilling assembly comprises a drill bit assembly, a cutting assembly, and both assemblies are fastened to a rotatable drive assembly. The drill bit assembly comprises a drill bit. The cutting assembly comprises a hole saw assembly. The cutting assembly is resiliently displaceable to the drill bit assembly. The drilling assembly comprises a displaceable membrane within the tubular body. The membrane divides an interior of the tubular body in a receiving compartment and an inner compartment.

This invention relates to a wireline tractor () for use in a casing or tubing () in a well. The wireline tractor () includes at least one retractable wheel () for driving within the casing or tubing () and a rotatable disc-shaped cutting device () mounted on an actuator () that is coupled to the wireline tractor. The cutting device () and the actuator () are configured for pressing the cutting device () against a wall of the casing or tubing () and for cutting a perforation () in the wall of the casing or tubing (), in operational use of the wireline tractor (). The invention further relates to a method for perforating a casing or tubing () in a well.

This invention relates to an activating tool () for connecting to and displacing a component () in a well tube (), activating tool () includes a driving device () axially displaced in two axial directions; a sleeve-shaped release element () with an annular end portion (); a gripper holder () arranged axially displaceable in release element () and displaced by driving device (); axially longitudinal recesses () in gripper holder (); at least two radially displaceable gripping elements () spring-biased in a radial outward direction, positioned in respective recesses () and complementarily fitting respective cut-outs () in the component (), and each gripping element () has a slanted rear portion (); gripping elements () retracted into release element () in passive positions of gripping elements (), and gripping elements (), at least partially, displaced out of release element () in active positions of gripping elements () so end portion () hits slanted rear portions () of gripping elements () when gripper holder () is pulled inwards in release element (), gripping elements () optionally switched between active and passive positions. A method for changing gripping element () in the activating tool () is described.

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.

This inventions relates to a stroker device () for use in a borehole () in the ground. The stroker () comprises at least an actuator () arranged for displacing a tool () in a longitudinal direction of the borehole () and grippers () arranged to anchor the stroker () to the wall () of the borehole (), alternatively to a pipe wall. The stroker () is provided with driving wheels () or driving belts for propulsion.
