ABSTRACT A simple, mechanistically based scheme for the calculation of pressuredrop in wells producing oil and gas single-phase liquid, bubble slugflow patterns is described checked with independent field data. The schemeis on an identification flow pattern through a modification theflow map Govier, Radford Dunn application themechanical energy balance form appropriate assuggested by Govier Aziz.

INTRODUCTION Many methods have been estimation pressure drop inwells produce mixture gas. These reviewed detail Most strictly empirical, but certain may be encountered offlow now developed. This especially true and, will discussed following paper, annular-mistflow gas-condensate wells. Orkiszewski has developed prediction anidentification selected mechanisticand empirical to individual patterns. His original appraisalincluded, among others, Poettmann Carpenter related correlations.The most accurate methods, Ros Hagedorn Brown werethen tested along his own against 148 well conditions.Orkiszewski's comparison showed that gave improved accuracy overthat Espanol et al confirmedthis from 44 different
