WITSML v2.1

The WITSML community is working on an update to WITSML v2.0, which will deliver WITSML v2.1. This version includes some bug fixes and an update of the directional survey portion of the model to make it in conformity with the latest thinking from the ISCWSA, who are the experts on well-bore surveying. The group is considering whether or not to carry over the sidewall core, conventional core and drilling target objects from 1.4.1.1.

WITSML ILAB (March 31st) and SIG (April 1 – 3 2020)
These meetings were initially scheduled to be hosted by AkerBP in Stavanger, but due to the Covid-19 situation, they were converted to virtual meetings with abbreviated schedules to accommodate multiple time zones. Meeting highlights include:
• ETP v1.2 testing shows good progress towards a release later this year. No major issues were found but some new capabilities have been added which will extend the testing period through July.
• An updated Practical Well Log Standard (PWLS) will be out for review in the near future. The latest version covers 4 major product lines: MWD/LWD, mudlog, drilling, and wireline.
• Two companies showcased how they are using WITSML. A small group of companies led by Bardasz is using WITSML to deliver data for realtime rig maintenance and surveillance. Then, in a very innovative approach, Exebenus is using WITSML to digitize standard operating procedures on the rig, improving accuracy, efficiency and safe operating practices.
• The technical team is working on a JSON representation of WITSML to support Open Subsurface Data Universe (OSDU) objectives.
• The Business Team is focused on how WITSML may enable analytics applications and the feasibility of a reference implementation to help developers/users.

RESQML

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

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.

ETP v1.2

The final ETP v1.2 Release Candidate 2 (RC2) is available for review and comments.

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) includes changes and new functionality to address feedback from the first release candidate, and to support workflows for eventual consistency between data stores.

Additionally, ETP v1.2 (when published) and WITSML v2.0 can be considered a complete replacement for WITSML v1.4.1.1.

The ETP v1.2 RC2 download package is a zip file that includes:

  • Avro schemas for each message of each ETP subprotocol
  • ETP v1.2 RC Specification document (pdf file) that describes required behaviors
  • An XMI file (which may be imported into any UML modeling tool)
  • A feedback form (to capture and submit your comments and issues during your ETP testing)

Industry stakeholders and interested parties are requested to download the package, review all materials, and implement/test those protocols that are relevant to their organization. Download the zip file here. Comments and issues should be submitted starting now until  February 15, 2021.

Note that Petrotechnical Data Systems (https://pds.group) has confirmed that they will make available a new version of their Development Kit for ETP that is compatible with ETP v1.2 RC2 by November 30, 2020, which will make it easier and more efficient to test code based on RC2. A technical walkthrough for developers is scheduled for December 17, 2020, more info here

PWLS version 3.0 Candidate Release

PWLS version 3.0 candidate release is available for public review until August 15, 2020.

The PWLS v3.0 candidate release (zip) includes:

  • PWLS 3 logs (xlsx)
  • PWLS 3 properties (xlsx and xml)
  • Public review kick-off presentation
  • 3 use cases for context (drilling safety, geophysicist, and regulatory)
  • Feedback form

A recording of the walkthrough presented by Energistics CTO, Jay Hollingsworth, also is available and may be useful for reviewers.

Three checkpoint sessions, approximately every 30 days, will be scheduled to review comments, to address questions that may arise during testing and to provide feedback in a live forum.

Please send feedback (preferably using the provided form), ask questions and let us know if you are interested in attending the 30 day review sessions via [email protected].

OSDU Participation

Since joining the The Open Group Open Subsurface Data Universe™ (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. See our OSDU page

This initiative also is an excellent example of collaboration between standards bodies (Energistics and The Open Group which hosts OSDU Forum) for the benefit of the industry at-large.

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.
