Well Log Data Compilation Workbook

THIS CONTENT MODEL HAS BEEN SUPERSEDED FOR WELL LOG OBSERVATIONS. This workbook is useful for data compiling, where databases can be sorted for use in various content models. However, for the express submission of well log observations, please use the newer Well Log Observation content model.

This workbook is designed as a guideline for compiling information from well log headers and well records. Information consolidated in this workbook will be used to populate multiple worksheets required to provide related services (the Well Header and Borehole Temperature data delivery ) and to populate Metadata records for single-source, well log documents and images (e.g. PDF, TIFF, JPG,  or LAS).  Basic information from the well log header is the basis for template header features used to index geographic locations with associated borehole information. The HeaderURI for a particular borehole (or well for simple wells) is the cross-referencing link (foreign key) used to associate the well header record, well log metadata, temperature measurements, and other related  types of data from a particular borehole. Typically, maximum temperatures are recorded on well log headers as 'bottom hole temperature' which is incorporated into the borehole temperature observation service. One row records one log’s data in the WellLogInformation worksheet and corresponds to an individual log run in a borehole; thus there may be multiple records per well to include various log types. For logs that are scanned or digitized and available as online resources, the resource provider and contact data will be created from the Dataset Metadata information worksheet.

Discussion: 

Each line is for one well log.  The log is linked to the Well by the HeaderURI.  Each log will have a Log URI.  If a log has multiple observations (for example, temperature), then those multiple values would be on a Well BHT template, with one row for each observed temperature, and including URI links to the Well Header and the Log URI.

Status

A content model for a well log feature services is now used.  Please see the content model here http://www.stategeothermaldata.org/data_delivery/content_models/well_log_observation. 

No schema exists for the well log compilation content model.
