Digital Mapping and 3D Visualization/Modelling of Subsurface Geology Using ArcGIS 9.2 and Well Log Data

Author(s) Mei, S. Date 2008-04-14

This is a step-by-step instruction manual of digital mapping and 3D visualization/modelling of subsurface geology using ESRI ArcGIS software and well log data. ArcGIS makes it possible to derive almost all of the building blocks for 3D visualization/modelling, including 3D wellbores, geological surfaces, cross-sections, fence diagrams, block diagrams, faults and geological solids, from a single shapefile with well log data, including well locations (x and y coordinates) and picks for geological formation tops (z value). The ArcGIS components include ArcMap, ArcScene and ArcCatalog applications and extensions, including 3D Analyst, Spatial Analyst and a third-party extension called XTools Pro that was developed by Data East, LLC of Russia. Simulated well log data, including formation picks and interpolated surfaces, derived from the Peace River Arch region in northwestern Alberta, are provided to assist with using the manual. Base map data, including rivers, roads, urban areas and a satellite image, are also included as an exercise.
