Communication Tool for Accessing a Non Annular Hydraulic Chamber of a Subsurface Safety Valve

A communication tool (100) includes a housing (102) having recesses (110) and a set of axial locating elements (112) radially extendable through the recesses (110) and engagably positionable within a profile of a tubing retrievable safety valve (50). An anti rotation device (140) is radially outward...

Beschreibung
Zusammenfassung:	A communication tool (100) includes a housing (102) having recesses (110) and a set of axial locating elements (112) radially extendable through the recesses (110) and engagably positionable within a profile of a tubing retrievable safety valve (50). An anti rotation device (140) is radially outwardly extendable relative to the housing (112). The anti rotation device (140) operably engages the tubing retrievable safety valve (50) to substantially prevent relative rotation between at least a portion of the communication tool (100) and the tubing retrievable safety valve (50). A cutting tool (148) is radially outwardly extendable relative to the housing (102). The cutting tool (148) is operable to create a fluid passageway (150) between a non annular hydraulic chamber (60) and an interior the tubing retrievable safety valve (50).
