Determining the water cut and water salinity in an oil-water flow stream by measuring the sulfur content of the produced oil
 Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations 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 relative presence of the elements sulfur, hydrogen and chlorine. From the sulfur measurement, the oil cut of the fluid is determined, enabling the water cut to be determined. From the determined water cut, water salinity can also be determined.
