Description:
Abstract:
An ESRI TIN data model of the overburden material above the Mahogany Zone was needed to perform calculations in the Piceance Basin, Colorado as part of a 2009 National Oil Shale Assessment.
Purpose:
Increasing energy demand, changing economics, new technology, and geopolitical issues have spurred renewed interest in other energy alternatives such as oil shale, heavy oil, and tar sands. The USGS Energy Resources Program has previously conducted extensive field and geologic research on these commodities and is initiating an effort to inventory and make these important legacy information assets accessible to the public, land managers, and other decision-makers. In addition, the Energy Program is scoping the geologic, technical, economic, and environmental factors controlling the production and use of these energy sources and will provide recommendations for future research in order to meet the energy needs of the United States.

Data_Quality_Information:
Logical_Consistency_Report:
The accuracy of the data contained in this TIN model is a reflection of the accuracy of the data contained in the original source maps, the scale of the source maps, the scale at which the original linework was digitized, and the interpolations and extrapolations of the source values during vector to raster conversion.
Completeness_Report:
The TIN model contains node values based on the thickness of overburden and variations (through interpolation and extrapolation) of those values above the Mahogany zone in the Piceance Basin, Colorado.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All TIN models have been peer-reviewed and are found to be geologically reasonable and accurate.

Process_Step:
Process_Description:
The original paper source maps were scanned, registered, and rectified and the top of the Mahogany ledge outcrop and structure contour lines were digitized in ArcGIS v. 9.1. Gaps in coverage near Battlement Mesa were contoured by hand by staff geologist and transferred to the digital polyline file. The structure contour lines were converted to a point file containing elevation values for the top of the Mahogany zone. For the Mahogany outcrop line surface elevation values in feet were extracted from a Digital Elevation Model (DEM) to obtain elevation values for the Mahogany ledge. The two point files were merged to generate a surface model in ArcGIS by using the GeoStatistical Analyst's Radial Basis Function (RBF) contouring method. The RBF surface model was converted to an ESRI GRID. The Mahogany surface GRID was then subtracted from a DEM GRID using the ArcGIS Spatial Analyst Raster Calculator. The resultant GRID contains values of total overburden, in feet, above the Mahogany zone for each one-acre cell. The resultant overburden GRID was converted to a TIN using the Mahogany outcrop as a hard clip line.
