Abstract

A retrofit assembly for functionally replacing a fluid isolation valve disposed in a borehole above a lower completion, including a barrier valve operatively arranged to selectively isolate the lower completion when the fluid isolation valve is open. The barrier valve is transitionable between an open position and a closed position due to engagement with an upper completion string. A packer device is included and operatively arranged to isolate a formation in which the borehole is formed.
