2 Contents From well head to the platform Heat transfer in Christmas tree Multiphase flow in long pipe Severe slugging in riser Sand transport in pipes Temperature effects in transportation of viscous oil Hydrate formation Slug flow around pipe elbow Riser V&V 3 phase separator Wave impact on platform Launching of lifeboat

3 Flow in and around a Christmas tree

4 Flow inside a Christmas tree

5 Temperature distribution inside a Christmas tree

6 Oil and gas flow in 100m pipeline

7 Severe slugging in riser, Uni of Cranfield, UK 1 Experiment Star-CD-1 Star-CD-2 Riser top Riser DP, bar inch riser Flow time t, s 10.5 m Riser base 55 m pipeline Riser DP = Pbase - Ptop

8 DEM particle transport in pipe

9 DEM - Pneumatic conveying of particles in pipe

10 Slurry flow in horizontal pipe Horizontal slurry pipeline flow Uniform solid volume fraction (vf) and slurry velocity (V) g Measurement plane 1m V D Liquid velocity L=10m Inlet Middle Outlet Particle volume fraction

11 Slurry flow in pipe Uniform solid volume fraction (vf) and slurry velocity (V) g Measurement plane 1m V D L=10m d=90 µm, vf=0.19, D=103mm, V=3 m/s d=270 µm, vf=0.2, D=51.5mm V=5.4 m/s d=480 µm, vf=0.203, D=51.5mm V=3.41 m/s d=165 µm, vf=0.189, D=51.5mm, V=4.17 m/s d=165 µm, vf= D=51.5mm V=3.78 m/s d=165 µm, vf=0.273, D=495mm V=3.46 m/s

12 Effects of cooling in transportation of viscous oil Temperature, density and viscosity after 200m. Temperature Density Viscosity 20 cp 120 cp

13 Wall shear stress and pressure drop along pipe Increase in wall shear stress and pressure drop as viscosity increases Shear Stress [N] With cooling Isothermal Sec. 01 A A Sec. 02 Sec. 03 Sec. 04 Sec. 05 Sec. 06 Sec. 07 Sec. 08 Sec. 09 Sec

14 A CFD hydrate formation model Oil-dominated 3 phase flow Oil Water Gas Hydrate + water Hydrate Eulerian multiphase flow model: Phase 1: Oil continuous fluid Phase 2: Gas dispersed bubbles Phase 3: Water/hydrate dispersed droplets (f H =0) turn into hydrate particles (f H =1)

15 Hydrate formation process 1. Methane (CH 4 ) from gas bubbles is dissolved into the oil. 2. Water droplets come into contact with dissolved CH 4, turn into hydrate particles when the temperature drops below the hydrate nucleation temperature. 3. The dissolved gas is consumed in the hydrate formation process. Oil Water Gas Hydrate + water Hydrate

16 Temperature, hydrate and dissolved gas Temperature of oil (Note areas cooler than hydrate nucleation temperature of 15.6 C.) Hydrate fraction in water (Hydrate starts to form when temperature drops below 15.6 C.) Mass fraction of dissolved gas in oil (Dissolved gas is consumed in hydrate formation and recovered when hydrate formation is completed.)

17 Pigging Overset mesh for moving pig Stratified gas-liquid flow Dispersed solid-liquid flow

18 Dynamic forces on pipe elbow in slug flow Model the long pipe using OLGA with slug tracking Pressure and temperature Mass flux, velocity and density of each phase Flow direction Model pipe elbow using STAR-CCM+

19 Pressure variation due to slug flow pass elbow Note the passing of liquid slug in blue. Note the increase in pressure as liquid slug passes. Gas volume fraction Pressure on the outer part

32 Conclusions CFD is becoming more widely used in flow assurance to study: Flow details in 3D: pipelines, equipment, junctions, valves, Thermal management, conjugate heat transfer, cold down, temperature dependent density and viscosity, hydrate, wax,... Fluid-structure interactions: VIV in risers, sloshing in tanks. CFD technology is being developed to support the modelling of the complex flows: Advanced grid generation methods. Advanced multiphase flow models. Fast parallel solver to handle large complex models. Powerful visualisation technique to explain the complex flow.
