3.4 Mapping WITSML LogCurveInfo to the ETP Index Metadata Record
Topic Version | 1 | Published | 10/16/2017 | |
For Standard | ETPW14 v1 |
The ETP IndexMetadataRecord is mainly constructed from the index curve of the WITSML v1.4.1.1 log. The table below maps the WITSML elements to the ETP attributes and calls out element examples from this example XML:
<?xml version="1.0" encoding="UTF-8"?>
