... when calculating the superficial gas velocity (uSG). Pressure Indicators (PI) and Differential Pressure Indicators (DPI) are used for the pressure measurements. On the flowline, one DPI is located at 206 pipe diameters from the water and air inlet, and a second one is located at 920 pipe diameters from...

... holdup will, according to the theory that the low solution is the stable one, end up at the low solution 2low, independent of the previous gas rate. The significance of this will be explained in Section 2.5. Figure 1. The liquid holdup as a function of superficial gas velocity, for a three- phase...

... that at low superficial gas velocities, flow behaviour along the flowloop is transient. Based on the experimental data, two different cases can be distinguished; namely, slug merging and slug dissipation. Figure 3. Toe-down. Slug frequency distribution along the well. Figure 4. Toe-down. Dimensionless slug...
