ABSTRACT:
The present invention relates to a method for measurement of total phase volumes in multiphase flow in pipelines. The multiphase fractions comprise hydrocarbon liquid phase and/or water phase and/or transported solid phases. One or more tracers are injected into the pipeline, preferably at the inlet and the tracer concentration(s) are measured as a function of time at the point of injection and at one or more points of measurements downstream from the point of injection. Further, the mean residence time(s) are measured for transport of the injected tracer(s) from the point of injection to said one or more point(s) measurements. The liquid phase volume(s) are calculated based on the amount of injected tracers and the measured tracer concentrations in each phase and the mean residence time.
