Fiber Optic based Survey Meter

About

This new radiation measurement system based on fiber optic dosimetry with ability to measure TENORM levels remotely and interior to the tubulars, in an intrinsically safe manner. The new system, built on the fundamentals of ionizing radiation induced luminescence, overcomes the limitation by having an optical fiber scintillator probe attached to a 10 meter extendable cable realized by a motorized cable reel. An optical fiber probe is electrically passive, immune to electromagnetic interference, chemically inert, make it suitable to be used in harsh environments. The new system, has the capability of remote measurement with good sensitivity and an acceptable signal to noise ratio set by the standards. Besides the scintillator probe, the cable is also equipped with a borescope camera, allowing visual inspection to be carried out. Both visual and TENORM readings are digitally recorded and mapped with distance in the tubular. Subsequently, these recordings are analyzed using a simple AI algorithm for eventual advisory on the condition of the tubulars, whether fit for re-use or re-cycle. The intelligent radiation measurement system would benefit the oil and gas industry by improving safety, reducing cost and processing time.
