Internal seminar presentation

1. Subsurface 3D GIS
Simple Reservoir Depletion Modeling
Using RMOTC Public Petroleum Data
blog.zolnai.ca

2. The Premise
• Users have tools at their fingertips they can use as-is:
• Esri not meant to replace full Geoscience apps
• Spatial Analyst extension: grid, contour, faults
• Includes Model Builder to concatenate processes
• 3D Analyst Extension to display subsurface data
• ArcGIS Explorer to distribute to wider audience
• There are other tools to link to Geosciences applications:
• Esri interoperability extension (Z-Map etc. files)
• OpenSpirit program interface (Scan Utility etc.)
• Data models (PPDM, PPDM Lite etc.)
• Others like Schlumberger Ocean etc.

3. Example GIS integration

field) seismic) fields) analog)

4. The data
• RMOTC
• Rocky Mountain Oilfield Testing Center
• NPR-3, Wyoming, Teapot Dome
• GIS, well and seismic data
• Released in 2005 at PNEC
• ArcGIS Online
• Posted same data on Esri community website
• Actual GIS dataset as-is and same terms as RMOTC
• 3D subsurface in ArcMap, ArcScene, ArcGlobe and ArcGIS Explorer
• Model Builder using a 15 year old idea from Statoil in Arc/Info
• Simple reservoir depletion model using current Esri tools

5. Rocky Mountain Oilfield Testing Ctr.

6. Reservoir Depletion Modeling
• Model Builder to apply old idea from previous generation
• Simply reverse reservoir topography
mimic the depletion of reservoir of its petroleum content
• Applying a surface run-off model
 the same way water flows downstream though gravity
• Petroleum will flow up-slope through hydrostatic recharge
• Very simple model with no rock properties etc.
• Not meant to compete with full reservoir models…
• but to show how experts can pass on models to others
 help spread the integration of GIS and Geosciences
