New model for two-phase oil/water flow. Production log interpretation and tubular calculations

This work presents the results of an experimental and theoretical investigation of two-phase oil/water flow behavior in vertical pipes. Bubbly flow is observed to be the predominant flow pattern, although at high flow rates, slug flow was noted. The proposed method, developed from the drift-flux principle, is validated by the authors' experimental data and those obtained from other sources. Limited study indicates the proposed method's superiority over others available in the literature. This work further shows the error involved when oil/water flow behavior is predicted by homogeneous, gas/liquid, and constant-slip models. Application of the model for production log interpretation is also documented.
