Abstract:
1. A method for characterizing a multiphase fluid produced by a hydrocarbon well, comprising the actions of: storing a time series of electromagnetic characterization measurements and non-electrical characterization measurements taken on a liquid stream of the multiphase fluid in a memory; filtering, by a characterization system, the electromagnetic characterization measurements and the non-electrical characterization measurements to remove measurements that are uncharacteristic of the hydrocarbon well during steady state operation; calculating, by the characterization system, a first water percentage of the liquid stream for each time in the time series based on the filtered electromagnetic characterization measurements; calculating, by the characterization system, a second water percentage of the liquid stream for each time in the time series based on the filtered non-electrical characterization measurements; and assessing, by the characterization system, an agreement between the first water percentage and the second water percentage for each time in the filtered time series to determine an overall data quality of the filtered electromagnetic characterization measurements and non-electrical characterization measurements.
