New model for two-phase oil/water flow: production log interpretation and tubular calculations Conference Paper uri icon


  • Flow of an oil/water mixture in vertical flow strings frequently occurs during production from undersaturated oil reservoirs. The undersaturated oil, characterized by the low saturation pressure, can cause liquid/liquid flow over a significant length of the producing string. A rigorous hydrodynamic model is needed to explain the physics of such oil/water flow so that the producing string and artificial lift can be properly designed. Such a model is also essential in interpreting production logs. 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 presence of slug flow is noted. The proposed model is validated by our experimental data as well as by data obtained from other sources.
