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 220.127.116.11.
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.
