Abstract

DGS01-1 includes the ArcView 3.x extension 3DWellField.avx.  This extension is used to generate and visualize three-dimensional (3D) shapefiles of well-field well-construction parts, inclined planes, packer-test results, borehole fractures, and geophysical logs based on borehole and rock-core records.  The extension is dependent on the ESRI ArcView 3D Analyst extension.  Data required for shapefile generation can be compiled outside of ArcView, then joined with a two-dimensional (2D) coverage of well locations in ArcView to generate and visualize the well-field components. The extension generates 3D multi-part shapefiles of well parts for cased, open, screened, and packer-tested intervals, 3D plane shapefiles of inclined stratigraphic contacts, water-bearing zones, and borehole fractures, and 3D polyline shapefiles of geophysical borehole logs. The extension also provides a tool for calculating the depth(s) of intersection for an inclined plane of known location and orientation for each well in the well field.  Instructions for loading the extension, organizing the input data, and executing the extension functions are detailed within the User’s Guide along with sample output.
