Note:		
The associated CSV file contains two header rows.		
This database contains the geologist's formation/sequence picks for the California Geological Survey's Preliminary Subsurface Geologic Model 25-01.		
The Kern River Formation does not have subsurface well picks.		
"Well API (UWI) does not include the leading ""0"", or the trailing ""0000"" to remain consistent with CalGEM records where the geophysical logs were sourced."		
The Well Known ID (WKID) reference code is equivalent to the European Petroleum Survey Group (EPSG) code.		
		
Definitions:		
Well	API	American Petroleum Institute unique well identification number
Surface_X	WKID_3310_meters	"Surface location (Easting) of the wellhead in the NAD83/California Albers projection, Well Known ID: 3310 in meters"
Surface_Y	WKID_3310_meters	"Surface location (Northing) of the wellhead in the NAD83/California Albers projection, Well Known ID: 3310 in meters"
Surface_Latitude  	WKID_4269	"Surface location of the wellhead in the NAD83 geographic coordinate reference system, Well Known ID: 4269 in decimal degrees"
Surface_Longitude  	WKID_4269	"Surface location of the wellhead in the NAD83 geographic coordinate reference system, Well Known ID: 4269 in decimal degrees"
Well_datum_value	meters	"Elevation of the well reference datum (e.g., kelly bushing, rotary table, well pad)"
TD_TVDSS	meters	"Total drilled depth of the well relative to sea level. TVDSS, true vertical depth subsea"
TD	MD_meters	Total depth of the well measured relative to the well datum along the wellbore
Bottom_hole_X	WKID_3310_meters	"Subsurface coordinate (Easting) at the bottom of the well in the NAD83/California Albers projection, Well Known ID: 3310 in meters"
Bottom_hole_Y	WKID_3310_meters	"Subsurface coordinate (Northing) at the bottom of the well in the NAD83/California Albers projection, Well Known ID: 3310 in meters"
PSGM_25-01__Fm_Seq	MD_meters	Preliminary Subsurface Geologic Model 25-01 measured depth of the  interpreter's respective geologic Formation/Sequence pick along the wellbore
