pocket 66 carrier 146 and insert 148 become axially and circumferentially aligned with longitudinal bore 60 of safety valve 50 once carrier 146 and insert 148 are axially and circumferentially aligned with longitudinal bore 60 of safety valve 50 communication tool 100 is in its perforating position as depicted in fig8 a u2013 8b in this configuration additional downward jarring on communication tool 100 of a sufficient and predetermined force shears pin 134 which allow punch rod 130 to move downwardly relative to main mandrel 132 as punch rod 130 move downwardly insert 148 penetrates radially reduced region 64 of safety valve 50 the depth of entry of insert 148 into radially reduced region 64 is determined by the number of jars applied to punch rod 130 the number of jars applied to punch rod 130 is predetermined based upon factors such as the thickness of radially reduced region 64 and the type of material selected for outer housing 52 with the use of communication tool 100 of the present invention fluid passageway 150 of insert 148 provides a communication path for hydraulic fluid from longitudinal bore 60 to the interior of safety valve 50 once insert 148 is fixed within radially reduced region 64 communication tool 100 may be retrieved to the surface as depicted in fig9 a u2013 9b in this configuration punch rod 130 has retracted from behind carrier 146 fish neck mandrel extension 128 has retracted from behind keys 106 and expander mandrel 118 has retracted from behind axial locating keys 112 which allows communication tool 100 to release from safety valve 50 insert 148 now prevents the upward movement of rod piston 68 and flow tube 72 which in turn.
