Choice of method for determining pressure losses during multiphase flow in vertical wells

Abstract

This article examines the selection of a method for determining pressure losses during multiphase flow in vertical wells. An analysis of methods used to determine pressure losses during vertical multiphase flow (Hagedorn-Brown, Beggs-Brill, Orkishevsky) is conducted for parameters that vary during well operation. It is demonstrated that the Hagedorn-Brown method provides the best results for small pipe diameters (3.5 inches) and low gas-oil ratios (611-938 SCF/STB), while the Orkishevsky method is preferable for larger pipe diameters (4.5 inches) and high gas-oil ratios (938-1898 SCF/STB).
