Wellsite Information Transfer Standard Markup Language

WITSML was initially developed by the WITSML project, an oil industry initiative sponsored by BP and Statoil, and later by Shell, as a new standard for drilling information transfer. Initial participation is from the major service companies Baker Hughes, GeoQuest, Halliburton, Landmark and Schlumberger. As of the completion of WITSML V1.2 in March 2003, POSC (now called Energistics) has custody of WITSML and is managing the support and future evolution of WITSML through the WITSML Special Interest Group. The aim of the WITSML standard is:

The “right time” seamless flow of well site data between operators and service companies to speed and enhance decision-making. 

All industry organizations interested in WITSML are invited to join the WITSML SIG. 

A bug-fix version of the WITSML 1.3.1 Data Schema Specification has been released. The 1.3.1 API is unchanged.

(December 6, 2007) Beginning very soon, the WITSML public web site will be re-launched using Energistics web facilities and will be closely linked with the Energistics main Web site and the PRODML public Web site. Click here to get an advanced look at the new site. Once launched the new site will use the www.witsml.org name. Watch for further announcements.
