The WITSML™ community is focused on delivering v2.1 later this year. The version which will consist of: bug fixes to address issues found during implementations of v2.0, updates to tool error model, datums handling and other enhancements, updates to leverage ETP v1.2, and updates to support alignment of WITSML with the OSDU™ platform. The Work Groups are also looking at methods to support migration from the first generation versions of WITSML to the second generation to help the industry leverage these improvements.

Spring 2021 WITSML SIG Meeting (March 22-26)

The Spring meeting was conducted virtually and was a mix of mostly technical discussions combined with business topics. Technical sessions led by Eric Griffith (PDS), Mark Farnan (Bardasz) and Nathaniel Burger (Scientific Drilling) looked at how to deliver wireline data, logs and channel sets, etc. via ETP, how to leverage the new PWLS v3.0, and various other issues. In addition, the The Work Group also discussed how to better enable migration from v1.4.1.1 to v2.0 as well as plans for v2.1. Testing focused on ETP v1.2 with WITSML v2.0, in preparation for publication of the ETP v1.2 standard which is due later this Spring. No major design or specification issues were uncovered during this or the past 2 ILABs; minor clarifications were captured and/or corrected during the testing session. The ETP DevKit has been updated for v1.2 and is available to developers. Watch for the release announcement coming soon!

Next meeting: Fall 2021 WITSML Work Group (September 14-17) - Virtual meeting


RESQML ILAB April 6-9 2020 This meeting was scheduled to be hosted by Eni in Milan but also was changed to a virtual meeting, allowing participation of members from many countries, all working from home. Highlights of this meeting include:

  • Discussion of two tools enabling RESQML development and implementation: RESQML Web Studio (Geosiris) offers conversions between RESQML v2.0.1 and v2.2; FESAPI (F2I-Consulting) enabling development in several languages.
  • Planning progressed for a simulation data deck pilot which will officially kick off on April 29th. One notable feature of this pilot is that it will utilize data from drilling, production and reservoir domains, showcasing an integrated family of standards.
  • Review of a Reservoir Domain Initiative proposed to OSDU which originated with Emerson and has the backing of Energistics’ RESQML community. This project will be led by Energistics RESQML members under the umbrella of OSDU.


PRODML v2.1 is now published and becomes the reference version. PRODML v2.1 represents an incremental change from v2.0, making changes only where implementation experience found deficiencies in v2.0. The only significant addition is the implementation of the Pressure Transient Analysis (PTA) capability. PRODML 2.1 is available on the Download page. A pilot is underway between two operators in the Gulf of Mexico for regular partner data exchange.


Version ETP v1.2 was officially released on September 14th 2021, superseding v1.1. The download page has been updated to offer the new version in addition to v1.1, and the ETP Users & Developers page is also updated. A web page goes through more detail about the new release, see here. The v1.2 ETP DevKit developed by PDS is being finalized and will be made available soon. More on the ETP DevKits here.


Practical Well Log Standard (PWLS) version 3.0 was published in March 2021. The PWLS v3.0 is available for download here. Full information on PWLS is available here. A recording of the walkthrough presented by Energistics CTO, Jay Hollingsworth,  is available and may be useful for those interested in the scope of this release.

OSDU™ Participation

Since joining the The Open Group OSDU™ Forum in October 2018, Energistics – both as an organization and as a member community – is fully committed to this industry initiative which puts data at the center of all activities and operations. Energistics standards – including WITSML™, PRODML™ and RESQML™ – are foundational to OSDU™ Forum. In addition to use of the standards, we are also contributing technical elements (manifest, parsers, code) as well as the combined intellectual capital from our community of experts and the expertise of our staff in key areas like documentation, enterprise architecture, data definitions, and project management.

WITSML – we developed innovative ingesters to allow key WITSML data types to be ingested into the OSDU data store, together with the associated metadata to permit subsequent search. We have also been working with all four cloud providers to ensure that these ingesters work within their specific frameworks, since each of the cloud platforms has services that are unique as part of their implementation of the OSDU Data Platform.

RESQML – we proposed the first OSDU Forum project to add reservoir data to OSDU Data Platform. This project utilizes RESQML as the fundamental building block for this since it is the only vendor-neutral format that can handle these complex data types, and our members are actively developing code to add this key functionality to the OSDU Platform.

PRODML – is a critical part of the Production project within the OSDU Forum since it has proven capabilities to convey production volumes, fluid types, well-test data, downhole and surface facilities, production hierarchies, etc.  It complements other standards that are focused on process control aspects of production.

ETP – (Energistics Transfer Protocol) was specifically developed for the type of high-performance real-time data exchange needed in the upstream – and not just between remote facilities and central monitoring centers, but also to connect applications in real-time.

UOM – Energistics is the custodian of Units of Measure for the industry and has contributed those to the OSDU Data Platform.

Data Quality – although not part of the OSDU Data Platform at present, the Energistics standards include a way to convey data quality through an entire workstream, so that the trustworthiness of the data can be objectively assessed and communicated to data consumers at each stage of the workflow.

PWLS – following a huge collaborative effort, the mnemonics reference library has been revised and updated and now covers over 45,000 entries for data channels associated with well-logging services across the industry.  It will be available to the OSDU Data Platform. This initiative also is an excellent example of collaboration between standards bodies (Energistics and The Open Group which hosts the OSDU Forum) for the benefit of the industry at-large.
