Flow assurance has been a major challenge in petroleum production systems especially in offshore operations where severe slugging is a dominant aching *** is characterized by pulsating flow behavior which impacts the reservoir productivity,pipeline-riser systems,and surface facilities(separator).The only means so far,of delivering reservoir fluids from offshore wells to the separator at the surface is by pipeline-riser systems where slugging is most prominent and oftentimes *** passive and active measures have been deployed over time to mitigate the associated problem,there is the need to develop a predictive tool for mitigating offshore slugging in the riser *** study involves the use of a model and analysis approach to eliminate severe slugging based on the balance of forces acting on the pipeline-riser *** stability criteria which consider accumulation and frictional pressure drops have been *** current approach is solely physicsdriven,to predict the corresponding liquid and gas velocities at which the fluctuations would be severe when producing multiphase fluids through pipeline-riser *** balancing the forces acting on a riser-pipeline system and accounting for frictional and accumulation effects,two hydraulic flow modeling approaches have been used in this study to improve the criteria for predicting the condition of severe *** developed criteria were computed using MATLAB/Simulink and a severe slugging flow map was ***“new study 1”and“new study 2”showed a 16%and 13%increase respectively in predicted unstable cases than the Malekzadeh *** criteria were tested at different separator *** Taitel and Jansen criteria could not predict severe slugging at elevated separator ***,the developed flow maps using the“new study 1”are more reliable than the“new study 2”.This is because the“new study 2”approach over defines the physics of severe *** cr
