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. A method of completing a borehole is also included.
