Abstract

An armored, 1/4" cabled, temperature sensor array was developed for oil and gas down-hole applications using Bragg gratings written into large diameter, single-mode cane waveguides to provide strain-isolated temperature sensor elements. The temperature sensor array was deployed and evaluated in a test-well. A measured temperature 1-σ deviation of better than 0.002°C and an overnight stability range of 0.02°C were demonstrated.
