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
