In this experimental study, measurements and observations have been carried out for high-viscosity oil/water/gas three-phase flows in horizontal and upward vertical pipes. Oil with viscosities between 0.15 and 0.57 Pa·s corresponding to temperatures from 37.8 to 15.6°C, filtered tap water, and natural gas at 2.59 MPa pressure are used as the three phases. Superficial oil and water velocities range from 0.1 to 1.0 m/s, and superficial gas velocity varies from 1.0 to 5.0 m/s. The internal diameter of the pipe is 5.25 cm. The experimental measurements include pressure gradient and liquid holdup. The flow-pattern and slug characteristics are observed and the images are recorded with a high-speed video camera system through a high-pressure sapphire window. The experimental results are compared with the predictions of the Zhang and Sarica (2006) unified model (UM), and the discrepancies are identified.
