PPDM Standards Collaboration

Proof of Concept (POC) to map WITSML and PPDM


Under the banner of the Standards Leadership Council (SLC), Energistics and Petroleum Data Management Association (PPDM) and their respective members joined forces around a proof of concept (POC) to map selected portions of WITSML and the PPDM data model.

The objectives of the POC included:

  • determine the feasibility and usefulness of a general mapping of these data models for specified use cases
  • gauge community interest to extend the mapping
  • identify best practices for development projects involving multiple standards organizations


The project team identified 5 high value use cases which involve 7 WITSML data objects and associated PPDM tables.

  • Move WITSML well data into an “empty” PPDM store
  • Move WITSML data into a populated PPDM store
  • Directional survey
  • Transfer real-time LWD data (e.g., gamma ray) using WITSML into PPDM data repository
  • Transfer LWD data (e.g., gamma ray) from a PPDM data repository to a WITSML-enabled application

The project team determined that:

  • It is feasible to map WITSML and PPDM but the result is a starting point for an organization, not a magic bullet.  Because organizations use data in different ways for different purposes, they may make different judgment calls when mapping data.
  • While there is agreement that mapping WITSML and PPDM is a good idea, this is not a high priority of the membership of either organization when considered against other development and adoption priorities.
  • Mapping WITSML and PPDM is a time- and labor-intensive process that requires dedicated time by subject matter experts of WITSML and PPDM.  There are no plans to extend the POC at this time but a project would be considered with proper funding and resourcing.


Energistics and PPDM leadership extend our sincere thanks and appreciation to the dedicated volunteers who worked on this project.  This project serves as an example of how standards organizations are working together for the benefit of the industry.
