the richness of data from LWD and rig data systems, drove BP and Statoil to explore a change to the standard. The initial project in 2000, DART ( Drilling Automation Real Time) was a CORBA approach, but this was dropped in favour of an XML based approach, that became WitsML. BP and Statoil passed custody of the new standard to Energistics in 2003. EnergyML EnergyML(tm) is the foundation for consistency and interoperability among all Energistics data transfer families of standards, including besides the WITSML Standards, PRODML(tm) for production and RESQML(tm) for reservoir characterization. Support for Distributed Temperature Survey Data A data exchange capability for distributed fibre-optic sensor (DTS) technology data was developed as an extension to the WITSML Standard based on previous work by BP. The DTS capability was reviewed and published with WITSML Standard Version 1.3.1 in December 2005. With the initiation of a related family of standards for production, PRODML, and its user community, the PRODML Special Interest Group, the DTS capabilities are being transferred to the PRODML Standards, which is more appropriate from a business function viewpoint. There will be no gap in support for DTS data exchanges as this transfer takes place.
