Method Of Controlling A Downhole Operation
Abstract: The present invention relates to a method for controlling a drilling or cutting operation performed by a wireline tool downhole comprising the steps of commencing a drilling or cutting operation in a downhole object such as a casing or valve; detecting vibration produced during the drilling or cutting operation in the downhole object using a vibration sensor adapted to transmit detected vibrations; processing a vibration signal from the vibration sensor to produce a real time frequency spectrum; comparing the frequency spectrum to a reference frequency spectrum; and controlling the operation based upon the comparison of the frequency spectrum and the frequency spectrum specification. Furthermore the present invention relates to a wireline tool for performing a drilling or cutting operation downhole and carrying out the method according to the invention.
