Presentation Transcript

  1. SPE 74480WITSML: Technology to Business (T2B) for the OilfieldJ.Holt, SPE, BP plc; I. Haarstad, SPE, Statoil; J.A. Shields, SPE, Baker Hughes; J.P. James, Schlumberger; D. Seiler, SPE, Halliburton Energy Services “A New Information Transfer Standard”

  2. History • Amoco Critical Drilling Facility and Advanced Drilling Facility • Chevron Data Center • Mobil Data Center • WITS (Wellsite Information Transfer Specification) • DART (Data Automation Real Time) • Proprietary Systems

  3. Project Goal • The “right time” seamless flow of well site data between operators and service companies to speed and enhance decision-making. Domain:Drilling, Completion, Well Services

  4. Existing Standards • WITS • Designed, implemented, and established as an industry standard in the mid eighties • A binary file format for transferring wellsite drilling data • No standard programming interface • Limited data objects • It was great for it’s time, but times have changed.

  5. Potential Scenarios

  6. Project Timing • Initiation of Project - Oct 2000 • Data Objects defined May 2001 • July 2001 – Working prototype • Wider industry roll-out at SPE Forum + Austin workshop 21/22nd Aug 2001 • Data standard design freeze 1st Oct, 2001 • January 2002 – Commercial offering by three major service companies and at least one small or midsize company

  7. Project Organization • Steering Board • Technical Teams • Data Objects • IT Architecture • Program Manager Companies involved to date:BP, Statoil,Halliburton, Schlumberger, BHI

  8. Software Design Decisions • Web Based & W3C Standards • Wide area networking • cross platform • XML data formats • Platform and language independent • SOAP for Programming Interface • Web server based • Platform and language independent • API Prototype in MS Visual BASIC

  9. Open Sourced Deliverables • Definition of Data Objects & Catalogs • Example WITSML files • Validation tool for WITSML files • Example code to read and write simple WITSML data files • Documentation

  10. WITSML API • Interface Definition • Prototype Implementation

  11. WITSML API - Interfaces • STORE (WMLS) Interface: Provides access to Persistent Store Returns/Accepts entire WITSML Data Objects as XML Documents • DOCUMENT (WMLD) Interface: Routes to Local or Remote STORE (WMLS) Interface Returns/Accepts entire WITSML Data Objects as XML Documents

  12. WITSML API - Interfaces • ITEM (WMLI) Interface: Provides access to WITSML Data Object at individual data item level (isolates application from XML) Provides synchronous validation against schema • REALTIME (WMLR and WMLP) Interfaces: Transport of REALTIME WITSML Data Objects Subscribe/Publish Paradigm

  13. WITSML API - Interfaces

  14. WITSML API - Network Protocol - Data Object Access

  15. WITSML API - Network Protocol - Realtime Transfer - Subscribe

  16. WITSML API - Network Protocol - Realtime Transfer - Publish

  17. Well Wellbore Rig Rig Equipment Pump Location Units Trajectory Target Bit Record Bottom Hole Assembly Wellbore Geometry Casing Scheme Open Hole Daily Operations Fluids Report Cement Job Log Real Time Mud Logging Data Objects

  18. Future • Data standard owned by on oilfield standards organisation • Still under discussion • Now has its own web presence • Seek alignment with other XML efforts such as WellLogML • Steering Board will continue • Original companies plus others

  19. Completions & Workovers • Define objects applicable to the completion and workover domain • Objects will be consistent with existing WITSML objects • Objects will cover the requirements for life-of-well

  20. Production Operations • Define objects applicable to the well-centric production domain • Objects will be consistent with existing WITSML objects • Surface production facilities will not be included in this phase

  21. Production Operations • Data object Examples • “Smart” completion data – sensor and actuator data, equipment settings • Well test data • Artificail lift operating parameters • Valve, sleeve and choke positions • Flow, pressures and temperatures

  22. Further Information • Web Site: www.witsml.org • Full details of object schemas • Documentation • Downloadable API components
