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.

A communication arrangement for communication between a downhole line and a wellhead body, the wellhead body having a wellhead body through-hole, a gate valve member for selectively closing the wellhead body through-hole, and a wellhead body port, and the communication arrangement comprising:
- a lower valve seat configured to engage the gate valve member so as to permit movement of the gate valve member relative thereto, the lower valve seat defining a lower valve seat through-hole and a lower valve seat fluid passage;
- and
- a communication member defining a communication member through-hole and a communication member fluid passage,
- wherein the communication member is attached to the downhole line, the lower valve seat is configured to co-operate with the wellhead body, and the communication member is configured to be run into the wellhead body through-hole and into the lower valve seat through-hole until the communication member fluid passage is aligned in fluid flow communication with the lower valve seat fluid passage so as to define a continuous fluid passage which extends from the wellhead body port to the downhole line.
A method of communicating between a downhole line and a wellhead body, the wellhead body having a through-hole, a gate valve member for selectively closing the wellhead body through-hole, and a wellhead body port, the method comprising the steps of:
- engaging a lower valve seat with the wellhead body so as to permit movement of the gate valve member relative to the lower valve seat, the lower valve seat defining a lower valve seat through-hole;
- attaching a downhole line to a communication member;
- and
- running the communication member into the wellhead body through-hole and into the lower valve seat through-hole until a communication member fluid passage defined by the communication member is aligned in fluid flow communication with a lower valve seat fluid passage defined by the lower valve seat so as to define a continuous fluid passage which extends from the wellhead body port to the downhole line.
