Abstract

A method of drilling or cutting through a blockage in a flowline using a remotely controlled electrically operated drilling or cutting tool that comprises a drilling or cutting means, a steering means, a pumping means, and a propulsion system wherein the drilling or cutting means is mounted on the steering means and the drilling or cutting tool has on¬ board electrical power supply means operable to actuate one or more of the drilling or cutting means, the steering means, the pumping means and the propulsion system, the method comprising: introducing the drilling or cutting tool into the flowline; actuating the electrically operated propulsion system to move the drilling or cutting tool through the flowline to the location of the blockage; actuating the electrically operated steering means so that the drilling or cutting means is aligned with the blockage; actuating the electrically operated drilling or cutting means so that the drilling or cutting means engages with and drills or cuts through the blockage; and actuating the electrically operated pumping means so that when the drilling or cutting means engages with the blockage, fluid that is present in the flowline adjacent the blockage is passed along the flowline with cuttings from the blockage suspended or entrained therein.
