ABSTRACT:
Methods and apparatus enable monitoring a hydrocarbon well for water within a flow stream of the well. A water detector includes a light source for emitting into a flow stream infrared light that includes a water absorbent wavelength band. A detector detects attenuation of the water absorbent wavelength band upon the infrared radiation passing through at least a portion of the flow stream. The water detector outputs a presence of water and/or a phase fraction or quantification of water as determined based on the attenuation. Detecting attenuation of a substantially transmissive wavelength band with respect to water simultaneously with detection of the attenuation of the water absorbent wavelength band can enable correction for non-wavelength dependent attenuation.
