A New Analytical Model to Predict Gas Rate Volume Measurement through Well Head Chokes

Historically, choke gas equations have been extensively used for gross estimation about gas volumes. These analytical models give a quick evaluation on gas volume but also face some serious limitations on specific topics like water presence, excessive gas velocity and pressure drop, limited differential pressure and high condensate to gas ratios. Many different efforts have being completed using several analytical models which can be applicable under certain conditions. This paper details a new predictive model for estimating the gas rate measurement through wellhead chokes and also covers all efforts for Saudi Aramco to get a single digit error on estimating gas rates for Ghawar gas condensate producers by implementing this new analytical model.
