  • Emulsion composition sensor
    Patent number: 10788407
    Abstract: A system for sensing an estimated composition of a produced fluid being conducted from a reservoir includes: at least one device for measuring temperature data; at least one device for obtaining flow rate data, pressure data, pump speed data and valve travel data; a first produced fluid density generator; a second produced fluid density generator; and a composition generator. The first produced fluid density generator is configured to generate a first produced fluid density based on the obtained flow rate, pressure, pump speed and valve travel data. The second produced fluid density generator is configured to generate a second produced fluid density based at least in part on the measured temperature data. The composition generator is configured to: iteratively generate a phantom component content, a bitumen content and a water content for the produced fluid based on at least in part on: a material balance of the produced fluid.
