Abstract:
A communication arrangement is disclosed for communication between a downhole line and a wellhead body having a through-hole and a valve member for closing the through-hole. The communication arrangement provides a fluid passage that extends from a wellhead body port to the downhole line thus allowing communication between the wellhead body and a safety valve or valves and/or the injection of chemicals or fluids into the well without the need to rework the valve member or disable the valve member.
