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


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.


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.

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.
