Pipeline 2 Times Longer

Research into severe slugging is aimed at the reliable prediction of its occurrence and of the associated slug length, frequency, and arrival velocity, all these has been studied in our base case. And also, we know that the gas and liquid flow rate, flowline inclination, riser-foot geometry, and liquid viscosity have effect on the occurrence of severe slugging. So in this part, we focus on the influence of the pipeline length.

We keep all of the characteristics of the pipeline-riser system and just change the geometry of the pipeline with 2 times longer as shown in the figure below.

We continue to take the same manipulation as the base case:

1. Drawing 3 turndown curve

2. Estimate the transition point in each turndown curve

3. Drawing the flow map
