Sand-control completion with permanent monitoring
Permanent downhole monitoring can provide valuable information for production decisions without requiring well intervention Co gather data. The full-length paper describes an openhole, horizontal, gravel-packed completion with permanent monitoring equipment in the production interval. The sandface completion includes two hydraulic lines in a U-tube configuration with a hydraulic wet connector at the top of the completion string. The completion is gravel packed by use of an alternate-path technology that decreases risk of failed gravel-pack placement caused by hole collapse or losses, Hydraulic lines provide a continuous, environmentally protected conduit for the fiber-optic line.
