... issues related to the transported fluid such as: pressure drop, liquid hold-up, hydrates, corrosion and sand. The recent subsea technology development, Pseudo Dry Gas System (PDGS), has demonstrated that deep water fields (~2000 m) can be transported long distances (~200 km) to existing processing...

... entrainment and deposition have relevant impact on annular flow properties, such as pressure drop and film thickness, as vastly shown in literature. Several authors have described physical mechanisms for droplet entrainment and deposition; many of those are related to disturbance waves. The objective...

... conducted at conditions that to a certain extent matched those expected during plateau production for the subsea gas development in Block 2 offshore Tanzania. One of the key concerns was that the presence of oil, water and MEG increases the frictional pressure drop more than current multiphase models...

... was granted access to use the data for improving the accuracy of the pressure drop predictions in LedaFlow. The experimental results showed that a key element for predicting high-rate low liquid loading flows accurately is to account for the droplets that deposit on the walls in the gas zone, creating a wall...

...). Dispersion viscosities derived from pressure drop measurements increased with higher dispersed phase fraction. However, the relative increase in viscosity was considerably less for the condensate – MEG system when compared with the model system. For all systems, a peak value of the viscosity was reached...

... ABSTRACT We consider the apparent roughness and increased pressure drop associated with the presence of a thin liquid film between the gas and the pipe wall in two- and three-phase stratified-annular gas-liquid flow. The main objective is to improve the pressure drop predictions for near...

... apparent being the lack of reliable multiphase flow models for flow in annuli, that is, flow between the inner and the outer pipe. Commercial multiphase flow simulators lack the ability to correctly predict pressure drop in annulus flow, even for single phase flow. Well design is thus based on crude...

..., results are presented for experiments which have been performed with a pressure controlled vessel attached to a vertical pipe. The pressure drop was varied to represent reservoir characteristics from tight to prolific. Liquid was injected using a mass flow controller. From these experiments...
