Abstract:
An apparatus for analyzing a multiphase flowing in a hydrocarbon well, comprising:a) a fiber optic probe having two ends, a first end adapted to be disposed in the flowing fluid;b) a light source having a first wavelength such that oil will fluoresce at a second wavelength in response to illumination by said light source, said light source being optically coupled to a second end of said fiber optic probe;c) light detection means optically coupled to said second end of said probe, said first light detection means for detecting light at said second wavelength and for providing a first output signal indicative of detection; andd) signal processing means for determining at least one of oil holdup, oil velocity, oil drop velocity, and oil volumetric flow rate based on said first output signal, said first signal processing means being coupled to said light detection means.
