..., and severe slugging in the flowline-riser. It can be concluded from the small-scale lab experiments that adding a surfactant mitigates (growing) slugs in (nearly) horizontal flowlines, whereas the severe slugging cycle in a flowline-riser configuration cannot be broken. foam configuration ppm...

... Abstract The effect of horizontal well trajectory on slug flow development was experimentally studied using a 2.0-in. ID flow loop to mimic different well trajectories. Inclination angle in the lateral section was varied ± 1° from the horizontal to simulate three well configurations, namely...

... frequency give a basis for a good force prediction. In general for multiphase conditions, the PSD shows a top-hat configuration. With the PSD, the force on a bend can be estimated. However, bends are never present isolated from the rest of the piping. For a complete structure, the forces on all bends...

... oil layer forms, while there is an accumulation of dispersed drops at the upper part of the pipe. The drop size evolution is tracked with a conductivity probe and is shown to depend on the spatial configuration of the flow. Introduction While there have been significant improvements over the last...

.... For the liquid flow rates tested there was a strong tendency for the liquid to split more or less evenly over the two risers, almost irrespectively of the back pressure imposed by the valve choking. takeoff experiment flow rate gas flow rate riser 2 configuration flowline valve nm 3 splitting...

... Abstract Interfacial wave characteristics have been studied experimentally in stratified-wavy configuration for air-oil two-phase flow at Tulsa University Fluid Flow Projects (TUFFP) 6-inch low pressure flow loop. Flow rates of each test fluid are adjusted such that the superficial gas...

... pipeline-riser configuration, different types of flow instability were found. 1 INTRODUCTION Pipeline-riser configurations in an offshore oil and gas production facility are required to transport multiphase hydrocarbons from a subsurface oil and gas reservoir to a central production platform...
