Abstract
Disclosed herein is a communication and lock open device which includes a lock open portion including a latch configured to engage a shifting profile on a closure member of a safety valve. Further included is a communication portion configured to rotationally align a cutter with a non-annular hydraulic bore in the safety valve and axially cut into the hydraulic bore with the cutter. Also disclosed is a method for replacing the function of a safety valve while employing an original control line including running a communication and lock open tool in a wellbore, locating the tool in a tubing retrievable safety valve and shearing a thread in the valve to render moveable a closure member of the tubing retrievable safety valve. The method includes shifting the closure member to lock the member in an open position, orienting a cutter and establishing fluid communication with a bore of the valve.
