Paper presented at the BHR 19th International Conference on Multiphase Production Technology, June 5–7, 2019
Paper Number: BHR-2019-167
.... IFE has recently developed and demonstrated scale-up rules for the most basic multiphase pipe flows. Earlier, the scaling rules were tested by designing experiments in IFE's medium-scale multiphase flow loop to compare with data from SINTEF's largescale facility. The focus of this paper...

... are sand particles, hydrates and wax. Depending on the flow rate, fluid condition, pipe size and sand properties, sand particles can either move along as suspended particles in the flow (dispersed), scouring along the pipe wall, as a bed of particles (dunes) or remain stationary. At high flow rates of oil...
