ABSTRACT:
The present invention is comprised of a non-intrusive microwave sensor system for measuring fluid saturation or multiple fluids contained within a flowline or a fluid saturated porous medium. Here, the microwave oil saturation scanner (MOSS) comprises a transmit portion and a measurement portion. The transmit portion generates two signals for different purposes. The first signal is used as a reference signal upon which the sample signal is eventually compared. The second signal is transmitted through the sample which causes a phase angle shift and signal attenuation. The two signals are then compared in the measurement portion where the phase angle shift and the signal attenuation is related to the concentration of oil and water in the sample mixture.
