Communication tool for accessing a non annular hydraulic chamber of a subsurface safety valve

摘要

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 ).
