Multi zone monitoring in boreholes

摘要

A multi-zone monitoring system allowing simultaneous measurement of separate zones of multi-zone well bore formations comprising a multi-component umbilical containing both electrical lines and a hydraulic fluid lines, an inflatable isolation packer that can traverse through the well bore and be inflated with hydraulic fluid to seal off a portion of the well bore wherein the inflatable isolation packer is connected to a hydraulic line of the multicomponent umbilical, wherein the inflatable isolation packer further comprises: one or more cable bypass feed throughs for the umbilical's electric and hydraulic fluid lines, wherein the hydraulic line is attached to the inflatable isolation packer with compression fittings.
