Abstract:
1. A method of driving completion equipment in a borehole, comprising the steps of: positioning the completion equipment in the borehole, the completion equipment comprising a liner; and moving the completion equipment along the borehole by operation of a downhole driving tool connected to the liner via an anvil extending from an end of the downhole driving tool, operation of the driving tool comprising accumulating energy in the driving tool and releasing the energy to force a moveable member against an impact surface of the anvil to provide a driving force which is applied downward on the completion equipment to move the completion equipment in the borehole; wherein the step of accumulating energy in the driving tool comprises providing energy to the driving tool by means of an energy source located at the surface selected from the group consisting of an electrical energy source provided by a wireline cable, a hydraulic energy source provided by a pipe, and combinations thereof.
