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.

A completion system comprising:
- a barrier valve operatively arranged in a tubing string to selectively impede fluid flow through a lower completion;
- and
- at least one control line for supplying a control line pressure for controlling operation of the barrier valve, the at least one control line operatively arranged with the tubing string for enabling tubing pressure in the tubing string to determine the control line pressure.
The completion system further including a plug interactive with a nipple to deliver tubing pressure to the at least one control line.
A method of operating a barrier valve, comprising:
- setting a tubing pressure in a tubing string by pressurizing a fluid;
- supplying the tubing pressure to at least one control line;
- setting a control line pressure in the at least one control line with the tubing pressure;
- and
- operating a barrier valve with the control line pressure.
