The root schema for WITSML Regulatory messages. This schema incorporates by reference a relevant subset of WITSML object schemas. The WITSML Server API does not currently support composite object schemas, such as this one. This schema is an integrated model of the relevant data objects, representing multiple object instances in one message. Data objects are integrated using an XML Schema hierarchy from well and wellbore. Plural data object root elements are represented by elements in the form "xxxSet" where "xxx" is the data object name. Well and wellbore content is present in generalInformation elements. This schema is derived from the WITSML Version 1.3 specifications. Extended scope is added to the well and wellbore data objects. The following represent proposed new WITSML data objects: boreholeInterval classifiedInterval classifiedPoint perforationInterval regulatoryDocument WITSML objects that were not needed within the context of this schema have been eliminated. uid attributes are optional. Information about the XML message instance. A collector for wells. A single well. Data object schema version. The fourth level must match the version of the schema constraints (enumerations and XML loader files) that are assumed by the document instance. The non-contextual general information for a well. A container element that contains elements that are common to all data objects. A container element that can contain custom or user defined data elements. The non-contextual general information for a wellbore. A container element that contains elements that are common to all data objects. A container element that can contain custom or user defined data elements. Human recognizable context for the well. General information about a well. A collector for regulatory documents.
