Measuring oil and water cuts in a multiphase flowstream with elimination of the effects of gas in determining the liquid cuts
 In a pipeline or container at any of various petroleum producing operations, a multiphase fluid flowstream containing oil, water and gas is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected. The spectra of the detected gamma rays are then analyzed to determine the ratio of the gamma ray counts of the element sulfur to the element chlorine. From this ratio, the oil and water cuts of the fluid may be measured while eliminating the effects of gas in the flowstream on the measurements.
