Basal Cambrian project GIS files were created based on outputs from the project’s geologic model. These files represent generalized characteristics of the Cambro-Ordovician Saline System (COSS) and are influenced by the model’s grid cell size, and, as a result, these data layers should not be used as an absolute value at any particular location. Within the basal Cambrian geodatabase are eight raster layers representing various geologic properties for the COSS derived from geologic modeling efforts. These include isopach, structure top, measured depth, permeability, porosity, pressure, TDS, and temperature. Values are generally in imperial units.

2015 Monitoring Seismic Survey at Bell Creek The raster layers represent a map of the RMS amplitude slice between the horizons Springen Ranch and the Skull Creek (Muddy Formation) enclosing the Bell Creek sand reservoir at the Bell Creek oil field. This gridded dataset was interpolated within ArcGIS based upon seismic amplitude values measured across the study area. Additional information regarding this data and interpretations can be found in the following document: Salako, O., Livers., A.J., Burnison, S.A., Hamling, J.A., Wildgust, N., Gorecki, C.D., Glazewski, K.A., and Heebink, L.V., 2017, Analysis of Expanded Seismic Campaign: Plains CO2 Reduction (PCOR) Partnership Phase III draft Task 9 Deliverable D104 for U.S. Department of Energy National Energy Technology Laboratory Cooperative Agreement No. DE-FC26-05NT42592, Grand Forks, North Dakota, Energy & Environmental Research Center, June. Monitor2015 contains 4 rasters: Clp2015ovr12 is the 2015 monitor survey clipped down to where it overlaps the 2012 baseline survey. Clp2015ovr14 is the 2015 monitor survey clipped down to where it overlaps the 2014 monitor survey. Clpdiff1512 is the RMS amplitude difference between the monitor 2015 and baseline 2012 survey. Clpdiff1514 is the RMS amplitude difference between the monitor 2015 and monitor 2014 survey.
