Multiphase Flow Simulation of Production Networks: Adding Value with GIS
Overview
Need Challenge Solution
The Importance of Understanding Multiphase Flow
Operations: Managing Liquid slugs & surges
GOAL: Safe and cost-effective transportation of fluids (Flow Assurance)
Design: Sizing pipelines & equipment
Pipeline Integrity: Managing Erosion & Corrosion

Upstream Downstream
Multiphase Flow Is Complex
More than $150 million has been invested in OLGA research and development since 1980
Sizing Pipelines
(dp/dl) = (dp/dl)elev.+ (dp/dl)fric.+ (dp/dl) acc. = - gsin (elevational) + - 2/2d (frictional) + - x d /dl (accelerational)
Terrain effects are important! pressure losses uphill are only partially recovered going downhill

How Can GIS Help?
GIS has been proven to add value for pipeline surveillance and operations – Primarily for transmission/distribution pipelines to date APDM & PODS are moving upstream – Multiphase gathering pipelines late to the party!
Overview
Need Challenge Solution
Solution
ArcGIS WPF Interface embedded within PIPESIM – Multiple basemaps – Support for shape files, layers, services Web Service to retrieve topology data
Quickly Build Pipeline Networks and Capture Elevation
Simulation Results – Elevation Profiles
Simulation Results – Pressure Profiles
Simulation Results – Liquid Holdup
Simulation Results – Corrosion Rates
Simulation Results - Slug Characteristics
But What About Flowsheets (PID’s)?
The London Tube – To Scale
The London Tube – Logical View
Both have their purpose!
Compare:
Gathering Network – Map View
Gathering Network - Schematic (Flowsheet) View
Future Plans
Capture of bathymetry data Link to environmental data (Ambient Temp, Wind Speed, Soil Type) Create networks from shape files Create networks via PODS/APDM 3D Visualization
Conclusions
Physics of Simulating Multiphase Flow Is Complex Elevation effects are critical GIS Integration Allows Rapid Model Building GIS Enabled Elevation Capture Ensures Accurate Results GIS + Flow Simulation Promotes Collaboration Between Disciplines
