An oil-water flow pattern classification and characterization method for wellbores was developed based on the integrated analysis of experimental data. The method includes frictional pressure drop, holdup and spatial phase distribution acquired in a transparent test section using a refined mineral oil and water. Tests covered the inclination angles of 90 degree, 75 degree and 45 degree from the horizontal plane. Six flow pattern paths were characterized in the upward vertical flow, three were water dominated and three were oil dominated. A mechanistic model to predict flow pattern transitions in vertical wells is presented. The model compares well with the measured data.
