Abstract
The main characteristics of different flow correlations were studied. An analysis of vertical flow field data for various tubing ranges indicates that no single order of rank can be stated concerning the accuracy of the correlations examined. Therefore, before planning production, it is always best to select the most accurate pressure drop calculation model on the basis of comparison with control measurements such as pressure, rate, gas/liquid ratio, and fluid properties. Even if the most applicable correlation is selected, it frequently occurs that the difference between the measured and calculated values are significant. Possible main reasons for this include measurement errors, paraffin or scale deposits, and unknown pipewall roughness.
