COURSE OUTLINE

MODULE 1
1.0. Fluid Properties and Phase behaviour modeling
1.1. Component of production system
1.2. Flow assurance concerns that need to be examined:


  • Pipeline rupture from corrosion
  • Pipeline blockage from hydrates or wax
  • Severe slugging can damage separator
  • Large pressure drop in pipelines can cause lower flow than should be


MODULE 2
2.1. Flow assurance strategies that need to be adopted:


  • Hydraulic Analysis – acceptable pressure drops, pipeline size, erosion & corrosion limits
  • Thermal Analysis – temperature distribution, heat loss
  • Inhibition Analysis – hydrate inhibitors, wax inhibitors, corrosion inhibitors, scale inhibitors


2.2. Flow assurance strategies Terms
· Beggs and Brill method
· Volume fraction, holdup and water cut
· Superficial velocity
· Mixture velocity and density
· Mass conservation
· Momentum conservation
· Energy conservation
· Mass transfer between phases
· Subsonic vs. transonic, supersonic and hypersonic flows

MODULE 3
3.1. Steady State Design:


  • Hydraulics
    • Line Sizing
    • Pressure Drop
    • Max./Min. Velocity
