Abstract

Methods and systems for testing a hydrocarbon well. Real time monitoring of the flow stream discharging from a well is used to collect physical and electromagnetic characterization data on the flow stream. A data filter is used to exclude data points uncharacteristic of the true performance of the well at that time in the operational cycle of the well. A statistical evaluation during or after at least some data has been collected is used to determine when the data set meets an acceptable level of data quality. The filtering parameters are adjusted to improve future detection, correction, and filtering of uncharacteristic data. Corrective transforms can be derived and applied to selected uncharacteristic data to recondition and retain the data. The filtered and completed data set is used to generate a hindsight determination of crude petroleum oil production output, including petroleum oil, water, and gas fractions and production rates.
