Abstract:
A completion system including a barrier valve operatively arranged in a tubing string to selectively impede fluid flow through a lower completion. At least one control line is included for supplying a control line pressure for controlling operation of the barrier valve. The at least one control line is operatively arranged with the tubing string for enabling tubing pressure in the tubing string to determine the control line pressure. A method of operating a barrier valve is also included.
