The Cognite WITSML extractor ingests data using the Wellsite Information Transfer Standard Markup Language (WITSML), version 1.4.1.1, into CDF. SOAP is typically used for historical data, while ETP is typically for real-time integrations, such as WITSML log objects. The extractor ingests WITSML non-growing objects, such as wellbore, into CDF RAW and growing objects, such as WITSML logs, into the CDF time series or sequences services. WITSML growing objects are characterized by the following:
  • A relatively large number of occurrences of recurring data is indexed to time or depth.
  • Additional occurrences of recurring data are inserted or updated over time. This is what causes the data object to grow.
You can configure the extractor using extraction rules that define what, how, and when to ingest WITSML data into CDF.

​
Run the extractor

The extractor is distributed as a Docker container, and you set a simple or advanced mode for low or high data volume integrations.
