This spreadsheet defines the schema used for the interchange of drill stem test observation results by the AASG geothermal data project for the National Geothermal Data System. The HeaderURI for a particular borehole (well for simple wells) is the cross-referencing link (foreign key) used to associate the header record, well logs, temperature measurements, and other information from a particular borehole. At minimum the data will report Observation URI, Well Header URI, Well Name, API No, DST Name, DST Operator, Lat Degree, Long Degree, SRS, DST Target Formation, Depth Top Open Zone, Depth Bottom Open Zone, Pressure Initial Shut In, Pressure Final Shut in, Hydrostatic Pressure, Source, and Information Source.
The idea is that each record (feature) in an interchange document represents an individual observation. Thus there are multiple records if there are multiple observations in a single borehole, indexed by depth to the open zone, procedure, and information source. It’s a data access format, so this results in lots of duplication of the header/indexing information, but keeps life simpler for the client application. Ideally formation and flow history will be reported.

Current services are deployed using content model version 1.8. The XML Schema for version 1.8 is here.
Version 1.9.1 was reviewed by the NGDS project technical teams and elevated to NGDS resources/public documents. This has not yet been pushed to public use, but the Excel Workbook documentation is accessible from that site.
