Evaluation of the Effect of Elevation on Terrain-Induced Slugging in a Riser System

This work investigates the impact of elevation on terrain-induced slugging in a riser system. Fluid compositions were modeled with multiflash and exported to OLGA readable PVT Table File. Pipeline materials properties geometry different develop flowline model. Two geometries (1 2) elevations defined establish their effect accumulated liquid volume flow, surge volume, slug length, number slugs density. The result shows that Geometry 1 total elevation(height)of 450 ft has flow 10.1058 ft3/s 2 elevation(height) 300 0.197822 for same time 2473.99 seconds. Also, 543.4608484 ft3 at drain rate 0.20843960 210.7395 0.23892 ft3/s. There was no length pipe while 531.78 indicating severe system elevation. density twice 1.
