  • Characterizing multiphase fluid flow
    Patent number: 9702745
    Abstract: A method and apparatus for determining multiphase flow characteristics inside production equipment containing at least two fluids. A pulse of heat from a heat source adjacent to the production equipment is provided, and a thermal response to the pulse is measured at each of a plurality of temperature sensors located adjacent to the production equipment. The thermal response measurement includes a time constant obtained from a measured decline in the temperature after the pulse of heat has been provided. The measured thermal responses are used to determine parameters of a fluid contained in the production equipment in proximity to each of the temperature sensors. The determined fluid parameters are in turn used to determine multiphase flow characteristics.
    Type: Grant
