This addendum report presents the results of the California Division of Mines and Geology (CDMG) drilling program at Calistoga, California, which was the final geothermal-resource assessment investigation performed under terms of the second year contract (1979-80) between the u.s. Department of Energy (DOE) and the CDMG under the State Coupled Program. This report is intended to supplement information presented in CDMG's technical report for the project year, "Resource Assessment of Low-and Moderate-Temperature Geothermal Waters in Calistoga, Napa County, California."

This spreadsheet is a compilation of borehole temperature observations compiled by the California Division of Oil, Gas and Geothermal Resources, published as a Web feature service for the National Geothermal Data System. The document contains 6 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 1814 wells are included. Fields in the data table include ObservationURI, WellName, APINo, HeaderURI, OtherID, OtherName, BoreholeName, Operator, LeaseOwner, LeaseNo, SpudDate, EndedDrillingDate, WellType, Status, CommodityOfInterest, StatusDate, Function, Production, Field, County, State, PLSS_Meridians, TWP, RGE, Section, SectionPart, Parcel, UTM_E, UTM_N, UTMDatumZone, LatDegree, LongDegree, SRS, LocationUncertaintyStatement, DrillerTotalDepth, DepthReferencePoint, Shape, TrueVerticalDepth, LengthUnits, ElevationKB, ElevationDF, ElevationGL, BitDiameterCollar, BitDiameterTD, DiameterUnits, Notes, MaximumRecordedTemperature, MeasuredTemperature, CorrectedTemperature, TemperatureUnits, TimeSinceCirculation, MeasurementProcedure, CorrectionType, DepthOfMeasurement, MeasurementDateTime, MeasurementFormation, MeasurementSource, CasingLogger, CasingDepthDriller, CasingPipeDiameter, CasingWeight, CasingWeightUnits, CasingThickness, InformationSource, DrillingFluid, Salinity, MudResisitivity, Density, FluidLevel, pH, Viscosity, FluidLoss, MeasurementNotes.
