Abstract
A method and downhole tool are presented herein for driving completion equipment in a borehole. The method comprises the steps of positioning the completion equipment in the borehole; and moving the completion equipment along the borehole by operation of a downhole driving tool connected to the completion equipment. Operation of the driving tool comprises accumulating energy in the driving tool and releasing the energy to force a moveable member against an impact surface in the driving tool to provide a driving force which is applied to 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.
