ABSTRACT:
Devices and methods for monitoring wellbore conditions while conducting hydrocarbon production within a wellbore, particularly an open-hole wellbore, having multiple zones within. A production tubing string assembly is made up having a plurality of packers for sealing within an open-hole wellbore having multiple individual zones. The production tubing string includes production nipples and one or more fiber optic sensor lines disposed upon the outside of the production tubing string. The sensor line or lines are disposed through the packers using a pass-through system so as to provide unbroken sensing line(s) to the surface of the wellbore. This allows temperature, pressure or other wellbore conditions to be monitored at the surface in each of the individual zones of interest.
