Abstract
A tubing retrievable safety valve () having a non annular hydraulic chamber () in a sidewall portion thereof is operable to received a communication tool () therein such that relative rotation between at least a portion of the communication tool () and the tubing retrievable safety valve () is substantially prevented. The communication tool () is operable to create a fluid passageway () between the non annular hydraulic chamber () and the interior of the tubing retrievable safety valve () by penetrating through the sidewall portion and into the non annular hydraulic chamber (). Thereafter, when a wireline retrievable safety valve () is positioned within the tubing retrievable safety valve (), hydraulic fluid is communicatable thereto through the fluid passageway ().
