  3. WITSML Evolution • Many different service companies monitoring the same well with incompatible software and hardware platforms • WITS in the 1980s • Used by Amoco, Chevron, Mobil to drive data centres • Point to point serial data transfer • Binary and ASCII data formats • Incomplete data set and out of date by late 1990s • WITSML in 2000 • Evolved from Statoil DART project (Java/CORBA) • Discussions with BP & Statoil, Baker Hughes, Halliburton & Schlumberger led to WITSML

  4. WITSML Charter The “right time” seamless flow of well site data between operators and service companies to speed and enhance decision-making.  • Sponsors • BP & Statoil • Participants • Baker Hughes, Halliburton, Schlumberger, NPSi • Organisation • Steering Board • Technical Team

  5. WITSML Implementation • Provides both a Data Model and an Access API • Web Based & W3C Standards • Platform & language independent • XML data formats • Human and application readable • Objects defined in XSD Schema • SOAP for Web Services • WSDL Defines data access services • Already used in other e-Businesses

  6. WITSML Data Objects • Well • Wellbore • Rig • Location • Trajectory • Target • Survey Program • Bit Record • BHA Run • Tubular • Wellbore Geometry • Operations Report • Fluids Report • Cement Job • Formation Marker • Core • Sidewall Core • Log • Well Log • Realtime • Mudlog • Message • Risk • Capabilities

  7. WITSML API • SOAP Interfaces defined in WSDL • Store Interface • GetFromStore() • AddToStore() • UpdateInStore() • DeleteFromStore() • Publish/Subscribe Interface • Subscribe() • Both Interfaces • GetVersion() • GetCapability()

  8. WITSML Progress • WITSML v1.1 Commercial Services in 2002/2003 • Limited to core set of WITSML objects • Small number of participating companies • SPE Paper 840662 • Presented in Denver, October 2003 • POSC custodianship in 2003 • WITSML v1.2 Commercial Services in 2004 • Additional WITSML objects supported • Other software vendors involved, new products introduced • Government agencies and standards bodies joined WITSML SIG in 2004

  9. WITSML Special Interest Group

  10. WITSML SIG • 8 Oil companies • 18 Service companies • 4 Government agencies/standards bodies • Steering Board • Regular conference calls • Use Case Group • Defines new requirements • Meetings at WITSML seminars • Technical Team • Monthly conference calls • Meetings at WITSML seminars

  11. Recent Developments • 5th Public Seminar and SIG Working Meetings Held in Paris in November 2004 • Version 1.3 Published for review Jan 2005 • Improved well location information • New Well Log & Risk objects • More robust and extensible schemas • Units validation via schema • Separation of Core and Data schemas • Server Profile definitions

  12. Future Plans • 6th Public Seminar and SIG Working Meetings in Houston May 2005 • Use Case Team Plans • Daily Drilling Reporting: led by BP, ChevronTexaco, and Hydro  • Completions and Well Mechanical Descriptions: BP, Statoil, ChevronTexaco, Paradigm, ExxonMobil, Hydro, and IFP • Other topics under consideration: • HSE data reporting • Distributed Temperature Survey initiative • Integration of Well Path and Well Log Data Transfer Standards • POSC Product Certification Program in Early '05
