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

WITSML Fall 2019 meeting in Houston
57 experts from 20 companies met at a BP facility in Houston for 3 days of information, discussions and decisions on WITSML. The technical session focused mainly on ETP v1.2 development, particularly as used with WITSML v2.0. We anticipate ETP v1.2 will be out for public review by year end. On the business side, attention is focused on WITSML v2.0 benefits beyond traditional rig-to-shore real-time operations. As we have seen in many contexts, analytics is becoming increasingly important and the Energistics community is focusing on how to better enable analytics using WITSML. To that end, the team kicked off an initiative to explore an optimal approach for WITSML data accessibility for data analytics platforms and applications. This will be a focal point for 2020.


The RESQML community is focused on completing the adoption of v2.0.1. In addition the community is working on guidelines for the use of ETP together with RESQML. Successful ILABs were completed in mid-May in Calgary, hosted by CMG, late August in Bordeaux hosted by F2I-Consulting and early December in Houston. The group prepared a live multi-vendor multi-cloud demonstration of RESQML that was shown at SEG 2018 in Anaheim (October), involving 6 software platforms from 5 vendors and 2 cloud instances. More on the pilot project and demonstration here.

RESQML ILAB in Pau (France), July 2019
Representatives from 10 companies, 5 operators and 5 vendors, met this summer in Pau, France, hosted by Total. One of the main topics of discussion during this meeting was to define requirements for a simulation data deck. The objective of this project is to extend use of both RESQML and PRODML to facilitate automation of data streams required to build and run a simulation model in initialization, calibration and/or prediction mode. This project is just getting under way, continuing through 2020.


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 ETP community is putting the finishing touches on a draft of ETP v1.2 which will be made available soon. The v1.2 update will include new protocols to introduce querying functionality while keeping the stable streaming protocols intact. There are also new protocols to complete the requirements for publish, subscribe in the data store and support for the use of ETP by RESQML.

Energistics Transfer Protocol (ETP) ILAB, September in Houston
During this ILAB, participants tested and compared ETP implementations using streaming native WITSML v2.0 data from an actively drilling well operated by AkerBP via Halliburton. This was the second time AkerBP has supported the Energistics community by providing live, streaming data during and after the ILAB. We recognize and thank AkerBP and their partners for this generous contribution to the Energistics/WITSML community.

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 early H2 2018.
