Subsurface 3D GIS Simple Reservoir Depletion Modeling

Using RMOTC Public Petroleum Data

blog.zolnai.ca

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.

Example GIS integration

Subsurf. (wells,

seismic)

Imagery (digital, analog)

Surface (productn,

field)

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

Rocky Mountain Oilfield Testing Ctr.

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
