Abstract
Sachdeva's choke flow model has been found capable of predicting critical-subcritical boundary and liquid and gas flow rates for multiphase crude systems. Although this model was shown to be accurate by Sachdeva et al. in their original paper using laboratory and field data, inaccuracy of the model has been found in other field applications. In this study, the accuracy of the choke model was evaluated using data from 239 oil wells and 273 gas condensate wells in Southwest Llouisiana. Comparisons of results from measurements and model calculations indicate that the model is more accurate for oil wells than for gas condensate wells. It was found that the error of the model could be minimized using different values of choke discharge coefficient (CD). For oil wells, CD = 1.08 should be used for liquid rate predictions, and CD = 0.78 should be used for gas rate predictions. For gas condensate wells, CD = 1.07 should be used for gas rate predictions, and CD = 1.53 should be used for liquid rate predictions.
