  1. WITSML Data Object Schemas (XML) • General • Well • Message • Operations Report • Real Time • Wellbore • Wellbore Geometry • Risk • Communication • Subscription • Server Capabilities • Coordinate Ref Sys • Drill Report • Attachment • Rig Instrumentation • Rig / Rig Equipment • Cement Job • Fluids Systems • Fluids Report • Surface Logging • Mud Log • Surveying • Survey Program • Target • Trajectory • Coring • Sidewall Core • Conventional Core • Logging While Drilling • Log  Well Log (includes Wireline) • Formation Marker • Directional Drilling Systems • Tubular / • Bit Record • BHA Run • Original • Updated • Added Source: BakerHughes/Paradigm

  2. User interface control Service companies WITSML:Vendor independent XML Application Data store WITSML Web Services • Web Services enables the selecting and transfer of XML objects on remote machines • Supports queries for real time and contextual objects

  3. WITSML Web Services (“API”) • SOAP Interfaces defined in WSDL • Store Interface • GetFromStore() • AddToStore() • UpdateInStore() • DeleteFromStore() • Publish/Subscribe Interface • Subscribe() • Both Interfaces • GetVersion() • GetCapability()

  4. Server Client Request Response WITSML: Transfer Methods • Informal, Discrete • Floppy disk file transfer of XML data files • E-Mail file transfer • On Demand, via Web Services API • Client-server model • SOAP Store Interface (GetFromStore method) • Accumulate and Propagate • Receive data from providers in near real-time • Support Subscribe via SOAP • Publish via HTTP POST

  5. WITSML Public Web Site

  6. WITSML V1.4 “README” • WITSML_v1.4rc_overview_and_normative-schema_30jul2008.zip contains the data schema definitions. • normative data schema specification XSD_Schemas/*.xsd and enumValues, UnitDict, and UnitClass • informative files: ./doc, ./XML_Examples, ./stylesheets, CHANGES.TXT file, /WITSML_Abbreviations.html • browsable overview ./doc/WITSML_Schema_docu.htm • browsable schemas ./doc/schema/*.html • WITSML_v140rc_Variant_Schemas_30jul2008.zipderived data schemas used with web services. • WITSML_v1.4rc_API_spec_and_API_schema_30jul2008.zipthe API specification and server schemas.

  7. WITSML_v1.4rc_overview_and_normative-schema_30jul2008.zip • Introduction • Data object schema design • Naming convention in schemas • WITSML Data Objects • Schema Variants • WITSML Schemas, XML Documents, and Stylesheets • Change Summary and Change detail file. • File to convert v1.3.1.1 XML files to v1.4.0.0 XML files.

  8. Introduction • Standards for sending well site information in an XML document format between business partners. • XML schemas define the content of an XML document. • Two specifications: Data Schema and Web Services. • A data object schema defines a set of data that can be transmitted within a single WITSML document and represents a cohesive subset (e.g.; well, wellbore, rig, etc.) of an overall logical schema related to a single domain (well). • Data object schemas contain attributes, elements, and included component sub-schemas.

  9. Data objects - 1 • aggregate: to transport multiple objects • attachment: a digital attachment to an object [base 64] • bhaRun: a run of the drillstring into/out-of the hole. • cementJob: a cement job. • changeLog: knowledge of object changes in a Server. • convCore: a conventional core. [geology, lithology] • coordinateReferenceSystem: defines a CRS in GML • drillReport: a daily drilling report to partners or agency • fluidsReport: an analysis of the drilling mud. • formationMarker: a geologic formation in a wellbore.

  10. Data Objects - 2 • log: the curves on an LWD well log. • message: informative message about a related object. • mudLog: the information in a mud log. • opsReport: a daily drilling report from service company • realtime: transient data in (near) realtime mode • report: provides context to objects in an aggregate. • rig: a drilling rig. • risk: risk information about other objects. • sidewallCore: a core from the side of a borehole. • surveyProgram: description of a directional survey.

  11. Data Objects - 3 • target: intended targets of a trajectory survey. • trajectory: a directional survey in a wellbore. • trajectoryStation: a single station in a trajectory survey. • tubular: the configuration of a drill string. • wbGeometry: the configuration of the permanently installed components in a wellbore. • well: general information about a well. • wellbore: general information about a wellbore. • wellLog: sets of logging curves within one run. Wireline supported.
