A communication tool (100) for communicating hydraulic fluid through a tubing retrievable safety valve (50) is disclosed. The tool (100) has a first section (102) and a second section (132) that are initially coupled together. A set of axial locating keys (112) is operably attached to the first section (102) and is engagably positionable within a profile (62). A radial cutting device (148) is radially extendable through a window (152) of the second section (132). A circumferential locating key (140) is operably attached to the second section (132) and is engagably positionable within a pocket (66) of the safety valve (50) when the first and second sections (102, 132) are decoupled, thereby circumferentially aligning the radial cutting device (148) with the non annular hydraulic chamber (60).
A method for locking out and communicating hydraulic fluid through a tubing retrievable safety valve having a non annular hydraulic chamber in a sidewall portion thereof, the method comprising the steps of:
A lock out and communication tool for insertion into a tubing retrievable safety valve having a flow tube and a non annular hydraulic chamber in a sidewall portion thereof, the tool comprising:
