| 发明名称 | Retrofit barrier valve system | ||
| 摘要 | 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. | ||

| 主权项 | 1. A retrofit assembly for functionally replacing a fluid isolation valve disposed in a borehole above a lower completion, comprising: a barrier valve operatively arranged to selectively isolate the lower completion when the fluid isolation valve is open, the barrier valve transitionable between an open position and a closed position due to engagement with an upper completion string; and a packer device operatively arranged to isolate a formation in which the borehole is formed, wherein the barrier valve and the packer device form at least a portion of the retrofit assembly that functionally replaces the fluid isolation valve. | ||
