ABSTRACT:
The total mass flowrate of a multiphase fluid flowstream such as a water, oil and gas mixture being produced from subterranean wells is determined by passing the flowstream through an apparatus which forces a substantial change in direction of the fluid flowstream and wherein a pressure differential is measured across flow paths of known cross-sectional flow area. The total mass flow is determined from the cross-sectional flow areas, the measured total density of the flowstream and the differential pressure. A sample of the flowstream is withdrawn from the flow path, gas is separated from liquid and the liquid fraction of water is measured by passing the liquid mixture through a device which measures the dielectric constant of the liquid mixture using microwave radiation transmissivity or differential pressure between columns of the liquid mixture and a column of water of equal height is compared. Total density of the flowstream may be obtained by measuring differential pressures across changes in elevation of the flowstream.
