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 SIG is 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 SIG 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!


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 (more about this later).
  • 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. More to come soon.


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.


The comment period for the final ETP v1.2 Release Candidate 2 (RC2) ended February 15 2021. The feedback is being reviewed and processed, the publication of version ETP v1.2 will happen in Q2 2021. ETP v1.2 and WITSML v2.0 will be considered a complete replacement for WITSML v1.4.1.1.

The Energistics Transfer Protocol (ETP) specifies messages and behaviors for the efficient transfer of data between software applications and technologies, including real-time streaming. ETP has been designed to meet the special needs of oil and gas exploration and production (E&P) data, and particularly the WITSML, PRODML and RESQML data formats.

The current published version, ETP v1.1, has been deployed in several experimental and operational implementations. Results show ETP reduces data latency to about 1 second—from 10–15 seconds, which is typical of SOAP protocols.  Also, ETP uses a binary encoding which requires 10x less bandwidth, compared to a purely XML format. These results mean faster, more efficient transfer of data for oil and gas operations, which ultimately supports faster and better decisions.

Based on real-world use and testing, ETP v1.2 RC1 (December 2019) delivered an enhanced design and added features to support existing and new E&P workflows. Significant new capabilities included:

  • More robust data-streaming protocols, which include a “simple streamer” for WITS-like data transfers, and two new streaming protocols—one producer-driven and one consumer-driven—to meet the various demands of real-time operations, including new workflows like auto-startup at the rig site.
  • New protocols and improved design to better support all Energistics data models: WITSML, RESQML and PRODML. While technically ETP v1.1 supported all Energistics data models, ETP v1.2RC1 now includes: a re-designed shared Discovery protocol; a new companion Dataspaces protocol; and new capabilities such as the DataArray protocol to transfer large, binary arrays of heterogeneous data values (e.g., for RESQML interpretation and modeling data and PRODML DAS data); and the Transaction protocol to ensure successful completion or rollback of a set of related tasks.
  • New query capabilities for Discovery, Store and GrowingObject protocols, which use an OData-like syntax. These advanced query capabilities help support existing and new industry workflows.

ETP v1.2 RC2 (November 2020) included changes and new functionality to address feedback from the first release candidate, and to support workflows for eventual consistency between data stores.

Note that Petrotechnical Data Systems ( made available a new version of their Development Kit for ETP that is compatible with ETP v1.2 RC2. This will make it easier and more efficient to develop code based on ETP v1.2. This can be accessed on Bitbucket here.
A new technical walkthrough for developers took place January 12, 2021, the recording can be watched here . The PowerPoint presentation is here.

More on the DevKit (current version) 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™  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™.

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/parsers 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 standard platform.

RESQML – we proposed the first external OSDU project as a post-R3 project to add reservoir data to OSDU. 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 OSDU.

PRODML – is a critical part of the Production project within OSDU 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 OSDU

Data Quality – although not part of OSDU 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 OSDU.

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.

See our OSDU page

OPC-UA Collaboration

OPC-UA standards are focused on the control of equipment while Energistics’ standards deal with the transfer and exchange of real-time measurements and descriptive data. The two sets of standards complement each other, and together enable the process control and time/depth-related information required for automated drilling and production systems. To help IT and decision makers plan and deploy the standards, our two organizations have been working on a joint document that will map the roles of the respective standards. We expect to publish the first version in the near future.
