Description
Abstract
ESRI GRID raster datasets were created to display and quantify oil shale resources for three zones in the Green River and Washakie Basins, southwestern Wyoming as part of a National Oil Shale Assessment. The oil shale zones in descending order are: LaClede Bed of the Laney Member of the Eocene Green River Formation, Wilkins Peak Member of the Eocene Green River Formation , and the Tipton Member of the Eocene Green River Formation. Each raster cell represents a one-acre square of the land surface and contains values for either oil yield in barrels per acre, gallons per ton, or isopach thickness, in feet, as defined by the grid name: *_b (barrels per acre), *_g (gallons per ton), and *_i (isopach thickness) 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.
Supplementary Information
This document serves as metadata for all oil shale resource models as defined by the grid name: *_b (barrels per acre), *_g (gallons per ton), and *_i (isopach thickness) where "*" can be replaced by the name of the oil shale zone.

Process step 1
Process description: Values from boreholes for variations of oil yield in barrels per acre, gallons per ton, or oil shale zone isopach thickness, in feet, were contained within the Access database "WYOS.mdb." These values were joined spatially to a borehole point data location file 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 eight neighbors in 8 sectors. Each GA model was exported to an ESRI GRID format using the appropriate analysis mask for each oil shale zone with a 63.615 meter (1 square acre) cell size and one point per cell for block interpolation.
