WITSML v2.0 available for comment

Friday, April 1, 2016

WITSML is the Energistics data exchange standard for specifying and exchanging data for wells and well-related operations and objects, such as drilling, logging and mud logging.

The main focus of WITSML is for the right-time, seamless flow of well data between operators and service companies to speed and enhance decision making.

WITSML v2.0 leverages the Energistics Common Technical Architecture (CTA), which delivers a common technology foundation for the Energistics family of standards-which includes WITSML, PRODML, and RESQML. This common architecture makes it easier for companies to implement the standards. It also makes it easier to share data "across" the standards, supporting common end-to-end workflows. For example, RESQML and PRODML can leverage well data in WITSML.

The last published version of WITSML, v1.4.1.1, specified a set of 27 data-object definitions and a Web services specification.

In v2.0, the primary changes include:

• A revised set of data objects. For a list, see Table 1-1 (page 8) of the included WITSML v2.0 Overview Guide.
• Replacement of the Web services API with the Energistics Transfer Protocol (ETP), which is part of the Energistics CTA.
• ETP v1.1 is under development and will be compatible with WITSML v2.0. A release candidate will be posted in the near future for public review and may be tested with WITSML v2.0 data objects.

The WITSML v2.0rc Overview Guide provides more details about v2.0 revisions. It is also included in the download package.
