Description:
Abstract:
ESRI GRID raster datasets were created to display and quantify nahcolite resources for eight oil shale zones in the Piceance Basin, Colorado as part of a 2009 National Oil Shale and Nahcolite Assessment. The zones in descending order are: L-5, R-5, L-4, R-4, L-3, R-3, L-2, and R-2. Each raster cell represents a one-acre square of the land surface and contains values for nahcolite tonnage. The gridnames follow the naming convention *_n, where "*" can be replaced by the name of the oil shale zone.
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.

Values and variations of nahcolite in weight percent for eight oil shale zones.
Process_Step:
Process_Description:
Values from boreholes for variations of nahcolite tonnage per acre for a specific oil shale zone were contained within the ESRI shapefile "Piceance_Nahcolite_Holes.shp." The shapefile was accessed in ArcGIS v. 9.2. The ESRI extension GeoStatistical Analyst (GA) was used to model each parameter using a multiquadric Radial Basis Function (RBF), with fifteen neighbors in 10 sectors. Each GA model was exported to an ESRI GRID format using an analysis mask which defined the nahcolite-bearing zone for each oil shale zone with a 63.615 meter (1 square acre) cell size and one point per cell for block interpolation.
