Method for single trip fluid isolation

摘要

A completion system for arrangement in a borehole including a lower completion, an upper completion string, and an intermediate assembly engaged between the lower completion and the upper completion string. The intermediate assembly includes a single barrier valve only. The barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitions to a closed position via the upper completion string when the upper completion string is pulled out of the borehole.

1. A completion system for arrangement in a borehole comprising:
a lower completion having an opening therein; an upper completion string; and an intermediate assembly engaged between the lower completion and the upper completion string, the intermediate assembly including a barrier valve configured to occlude flow from the opening in the lower completion when the barrier valve is closed and the intermediate assembly is engaged with the lower completion, the barrier valve operatively arranged to be maintained in an open position when engaged with the upper completion string and configured to transition to a closed position in response to the upper completion string being withdrawn from the intermediate assembly.
