Abstract
This disclosure describes a fiber optic based pressure transducer that detects position of a heated end of a Bourdon tube under pressure. This movement can be calibrated to provide an accurate pressure reading. The temperature change in the fiber due to the heated end of the Bourdon tube is detected using DTS (Distributed Temperature Sensing) techniques, which additionally measures the temperature along the entire length of the well. Thus one surface instrument can provide both an accurate temperature profile of a deep well and its pressure at critical locations. This is of value for the testing and production stages of the well. No electrical cables are required, and all signals are conducted through a single optical fiber that is also the detection fiber. Multiple pressure sensors can be installed on the fiber and their pressures determined.
