THIS CONTENT MODEL HAS BEEN SUPERSEDED BY FLUID FLUX BOREHOLE OBSERVATION. PLEASE SEE http://repository.usgin.org/uri_gin/usgin/dlio/577. This spreadsheet indicates the content requested for fluid production data obtained from geothermal wells for the AASG geothermal data project. Typically production volumes are recorded from reports, and this information will be provided through a fluid production service. The HeaderURI for a particular well is the cross-referencing link (foreign key) used to associate the header record, well logs, temperature measurements, and other information with the production record.

This paper investigates the practical range of net power capacity available from conventional and Enhanced Geothermal System (“EGS”) wells as a function of temperature. For a geothermal resource temperature up to about 190°C, which is the operating temperature limit of presently available downhole pumps, wells are typically pumped and power is usually generated in a binary-cycle plant, and in rare cases in a flash-cycle or hybrid-cycle plant. In this temperature range under the current state of downhole pump technology, the net MW capacity of a well has a practical upper limit of about 7.3 MW, irrespective of how high the well’s productivity index is. This capacity limit cannot be improved unless technology can be improved to allow pumping at a higher rate than the present practical limit of about 160 l/s (2,500 gallons per minute); improving the temperature tolerance of pumps, by itself, will not increase this capacity limit. For resource temperatures greater than 190°C, wells must be self-flowed, and power is generated from such wells in a flash-cycle or hybrid-cycle plant.

This spreadsheet is a compilation of borehole temperature observations compiled by the Oregon Department of Geology and Mineral Industries, 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 5192 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, ObsID.
