Stackable multi-barrier system and method |
| 摘要 |
A multi-barrier system includes a first valve in fluid communication with a lower completion that is electrically actuatable and inductively coupled to an upper completion. Also included is a second valve in fluid communication with the lower completion, both the first valve and the second valve, positioned proximate an uphole extent of the lower completion, are closable in response to retrieving the upper completion and openable subsequent reengagement of an upper completion. |

1. A multi-barrier system comprising:
a first valve in fluid communication with a lower completion being electrically actuatable and inductively coupled to an upper completion; and a second valve in fluid communication with the lower completion, both the first valve and the second valve being positioned proximate an uphole extent of the lower completion, and both the first valve and the second valve being closable in response to retrieving the upper completion and openable subsequent reengagement of an upper completion, and both the first valve and the second valve being configured to prevent flow through an opening in the lower completion created by retrieval of the upper completion when the first valve and the second valve are closed.
