SAFETY VALVE AND METHOD OF INSTALLING SUCH A VALVE IN A WELL

摘要

A safety valve (10) comprises a pre-installed penetration member (14). The penetration member is installed into the safety valve before installing the safety valve in the well. The penetration member is coupled to a cable (20) which communicates with a downhole component, such as a gauge (18). Pulling the penetration member upward pulls the cable upward through the safety valve.
