Abstract
A technique enables sensing one or more wellbore parameters along a specific well zone. A section of instrumented coiled tubing is provided with a sensor array extending along its exterior. The sensor array is designed to sense well fluid related parameters and may comprise an optical fiber sensor. A cross-over allows the sensor array to communicate with a surface location via a control line routed along a coiled tubing interior.
