... ABSTRACT Experiments were performed with propose of mapping the flow patterns in two-phase flow in an upward inclinable 60 mm ID and 6 m long Plexiglas pipe. Air and viscous oil were used as working fluids and degree of inclination changed from 10 ? to 78 ?. Measurements includes pressure drop...

Two commercially available anti-agglomerant additives (AA-1 and AA-2) were tested in gas / condensate / water system at two water cuts under different multiphase flow regimes. The tests were analysed based on pressure, temperature and pressure drop measurements...

...) systems, which have been observed in modeling to under predict pipeline pressure drop. This is a significant issue because the pressure margins in onshore gathering systems are tight and, in some instances, a ±1 bar difference in expected pressures can dictate how the system is operated. The primary...

In addition, traversing gamma densitometers were mounted on each of the two near-horizontal sections to measure the time-averaged liquid distribution and volume fractions. In this campaign...

... Abstract Measurements of the pressure drop and liquid hold up in a gas flow with wet walls were carried out on a vertical pipe at NTNU Multiphase Flow Laboratory. The experiments were performed as a dry-up process, where an initial liquid film becomes thinner with time as it is removed by gas...

... Abstract Oil and gas reservoirs are tested by performing a shut-in test. A new down-hole shut-in valve has been installed in a multiphase flow loop and the pressure drop over the valve has been investigated for single phase and two phase flows. The flow path through the valve is a 3 meter long...

... ABSTRACT: Three oil-water-gas flows experiments have been carried out in a 68 mm ID pipe with a dense gas (simulating high pressure flows) and with oils of different viscosities (1.8–100 cP). Measurements include pressure drop and liquid entrainment using an isokinetic sampling probe. The flow...
