Abstract
A running tool for running an apparatus for patching a wall of a downhole casing and activating the apparatus in a location in the conduit includes a rolled up or curled up piece of material for patching the wall. The piece of material has a surface comprising an adhesive compound for fastening the piece of material securely to the wall of the casing. The running tool has a heater for providing heat for the apparatus for heating the compound and a forcing device for applying a force to the piece of material for forcing or holding the piece of material against the wall of the casing.
Claims17
A running tool for a downhole apparatus for patching a wall of a casing in a wellbore, wherein the apparatus comprises:
- a plurality of pieces of material for patching the wall of the casing,
- wherein the running tool comprises one or more compartments configured to hold the plurality of pieces of material for being released for patching the wall of the casing, and wherein the running tool is arranged for allowing selective release of the plurality of pieces of material, wherein the running tool further comprises:
- a forcing device configured to apply a force to each said piece of material for forcing or holding the piece of material against the wall of the casing,
- wherein the forcing device includes an expandable device, and
- wherein the tool further comprising a hydraulic actuator configured to expand the expandable device.
