WITSML V2.0 data schemas

Preferred version for new and upgraded production implementations.Use with Energistics Transport Protocol v1.1.

 

Beginning with v2.0, WITSML leverages the Energistics Common Technical Architecture (CTA), which delivers a common technology foundation for the Energistics domain 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 for integrated operations 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, main changes include:
  • A revised set of data objects. For a list, see Table 1  of the WITSML Technical Usage Guide.
  • Replacement of the Web services with the Energistics Transfer Protocol (ETP), which is part of the Energistics CTA.
The Technical Usage Guide describes each WITSML data object, including its business use and an overview of its design.
