National Renewable Energy Laboratory (NREL)

Packed ArcMap project database for the northern Steptoe Valley model area. 

Play Fairway Steptoe Valley.mpk

GeoSoft Oasis montaj project containing GM-SYS 2D profiles and associated data. No forward modeling. Use to construct Adobe Illustrator profiles.

2D Gravity Profiles.zip

Polyline shapefile of extensions of seismic lines. Used to generate "wing points" at 500 m intervals to sample the gravity grid. Gravity models suffer from significant edge effects. The gravity dataset was sampled beyond the ends of each seismic reflection line for accurate forward modeling.

Seismic Lines.zip

Spreadsheets of gravity profile data extracted from the Nevada Play Fairway 2015 compilation grid on 500 m centers, along 10 SEI seismic reflection lines. Extracted for forward modeling in Oasis GM-SYS 2D and combined interpretation with the seismic reflection data.

Gravity Profile Data.zip

Point shapefile of gravity point locations in SteptoeValleyGravityProfileData zip folder. Gravity data was extracted from the 2015 Nevada Play Fairway gravity compilation grid on 500 m centers, along the trace of our seismic lines for cross-section interpretation.

Gravity Point Locations.zip

Compressed folder containing all image & data files used to generate the 3D model in DGI EarthVision, stripped of proprietary seismic reflection data. And the 3D model files themselves.

EarthVision Model Files.zip

Geodatabase (.gdb) containing: 1) A polyline shapefile of basin depth contours clipped to the Steptoe Valley basin, 2) a point shapefile of geologic attitudes covering the SW 1/4 of the model area (from existing pub: NBMG M35), 3) miscellaneous rock unit data, 4) a clipped and re-projected point shapefile of well collars in the Steptoe Valley model area, derived from published well collar datasets available in NBMG M162 (see links spreadsheet), and an interactive map of Nevada geothermal wells (NBMG website).

Steptoe Valley Geodatabase.zip

Point shapefile of attitudes for rock units exposed in the ranges surrounding Steptoe Valley. Contains attitude data digitized from mapping by Dechert, Poole and Adair. Covers the northern and eastern 3/4th of the model area. Attitude data for the SW quadrant of the model area was taken from an existing published dataset, (see links spreadsheet, NBMG M35).

Geology Attitude.zip

Polygon shapefile subset from SteptoeValley_geology; used to clip basin depth contours in Steptoe Valley.

Basin Geology.zip

Polygon shapefile of major rock unit packages in the Steptoe Valley project area, broken out by age. Simplified from Geology and mineral resources of White Pine County, Nevada, 1976, Hose, R.K., Blake, M.C. and Smith, R.M., NBMG Bulletin 85, plt 1, scale 1:250,000.

Geology.zip

Spreadsheet containing descriptions and URI links to geologic maps and selected geophysics maps for the northern Steptoe Valley basin model area.

Geologic and Geophysical Map Links.xlsx

Polyline shapefile of leased SEI seismic lines, Steptoe Valley. 
UTNM NAD 83 z11N

SEI Seismic Lines.zip

Compressed folder containing: .xlsx compilation spreadsheets of well data for Steptoe Valley model area. Listed: drill date, type (oil & gas, geothermal or other), location, depth, lithologic intervals, availability of cutting & logs, borehole geophysics and deviation. Logs and images of borehole data for some wells reviewed for use in this study are held in separate folders under well name or Kettleman number. Also a point shapefile of Steptoe Valley well collars from the NBMG database, clipped and re-projected to UTM NAD 83 z11N. Includes all oil&gas and geothermal, but no TGH or mining drillholes.
