Prognosis Poise

Prognosis Poise is an exceptional flow metering problem. Prognosis Poise is notoriously difficult to meter by conventional means due to fluid viscosity, and therefore Reynolds number and flow coefficient being unknown. While for gases and most liquids, even moderate biases in viscosity prediction have minimal effect on the flow meter outputs, even small heavy oil viscosity prediction biases have very significant effects on heavy oil meter outputs. And unlike regular gas and liquids, heavy oil viscosity changes vary significantly with even small changes in oil grade and temperature. Hence, an unknown or incorrectly predicted heavy oil viscosity can induce significant flowrate prediction biases. A DP meter with Prognosis calibrated across a meters Prognosis Poise range can use Prognosis to predict the actual viscosity in service, and hence the flow coefficient and correct flowrate.
'Prognosis Poise' solves this problem. 'Prognosis Poise' utilizes a DP meter's DP Ratios of a suitably calibrated DP meter to accurately estimate a heavy oil flow's Reynolds number, and the associated fluid viscosity, meter flow coefficients, and fluid flowrate.
