This enable information sharing and efficient collaboration across disciplines and between operators, partners, authorities and their suppliers.

6. Production data project- Overview • Goals • One Industry solution in Norway – with all major stakeholders • One common set of definitions for an extensive set of terms used in the production area (data elements) • Standard solution – available for all, built on well known and proven international standards and structures • Steps • Define common production terms (Implemented as ISO 15926) • Develop XML exchange format (Based on POSC WITSML) • Implement a data exchange solution for the North Sea Oil&Gas fields (Based on existing hub, LicenseWeb) • Benefits • Easy information sharing between companies/applications/work processes • Strong and flexible XML structure enabling dynamic reporting possibilities (Aggregations of data over time and cross fields/wells ) • Allows for timely decision making • An important step to achieving full eOperations advantages

7. Production data project- Data definitions • Development and implementation of a new RDS (Reference Data System) with infrastructure, procedures and documentation • RDL (Reference Data Library) data according to ISO 15926. • Production Data elements are defined for use (1500 terms) • All Oil&Gas Operating Companies in Norway has agreed on the definitions • One common set of definitions across companies and fields to achieve common understanding of terms

8. Production data project- XML standard exchange and reporting format • According to international standards (POSC) • WITSML / PRODML cooperation and compliance • W3C standard • We have worked closely with POSC to agree on a structure flexible enough to handle both data exchange and reporting including aggregation of data. • We have established a generic database for exchange of XML documents and other documents • Is currently implementing the standard in this database

9. Standards & POSC- Outcome of cooperation with POSC • Agreed on a common approach to XML format • Established a common understanding for business and reporting needs • Agreed to a common approach for solving issues related to relationship between production data and different field facilities (e.g. well, platform, pipeline) • Agreed upon a more reusable XML structure more suited for a global production data approach • Agreed on XML structure that will support both reporting needs and possible data exchange needs • Agreed XML structure supports different reporting requirements • Final outcome: A format suited for more than production data reporting

10. XML schema, structure and format - TE / POSC Co-operation results • Value added • Allow combination of hierarchical and flat structure • Hierarchical -> parent/child relations e.g. facility->template->well->wellbore • Flat -> flexible/generic – very suitable for data exchange • Suitable for both reporting, data exchange, monitoring and analysis / aggregation • Data extraction to generic format – allows multiple output pipes • Allow more complex data analysis / aggregation • Based upon already existing data exchange format : WITSML • Format supports globalization of data • Supports a combined snapshot capturing of data and current field setup • Highly object oriented structure -> high reuse • Format anchored as a part of a possible global standard promoted by POSC / TE • PRODML Work Group

11. Production data project - Project plan • Project start: October 2004 • Definition of terms: October 2004 – May 2005 • Coding of XML: May 2005 – October 2005 • Energy Components • Generic XML database (LicenseWeb) • Testing Valhall (BP) and Åsgard (Statoil): October 2005 • Evaluation of the testing November 2005 • Approval process in OLF: December 2005 • Implementation in the licenses : January 2006 –

12. Production data on XML format from production system XML-processor receiving and storing XML files (alongside with text and html based version for printing/viewing) Daily activity and production data reported to partners Monthly production data reported to authorities Data definitions is incorporated into standard ISO-15926 XML scheme made by TE and forms new POSC standard (WITSML-Production) Possible to aggregate data Fully automated process All work performed by TietoEnator Reporting of production data Operator LicenseWeb/ AuthorityWeb Authorities/ partners XML-file Production System XML processor XML- file Text- file LicenseWeb/ AuthorityWeb Partners Daily prod data Monthly prod data Authorities

13. Technical solution Generic XML DB (LicenseWeb) Partner/Operator Operator XML file Non std reports Reference Data Library (ISO 15926) XML file Make std reports Storage of documents/XML Spesial reports Internal Prod. data system XML Std Prod rapport Prod report Excel rapporter License Web Valhall Åsgard XML

14. Reporting of performance data- Performance related reporting LicenseWeb/AuthorityWeb Queries Reports XML Interface Oilfield Performance Data • Possible to expand on performance figures (prod, drilling, HSE, finance, etc.) • Graphic and textual representation • Automatic reporting using XML Operator databases

15. license operator Partners LicenseWeb • Web-based solution for digital processes/archive for authorities and companies and within license management (concessions) • Dramatically increased efficiency of Authority and License management processes • Used in NCS and DKCS • Authority organisations • 250 licenses • 40 companies • 6000 users • Used by Statoil’s international licenses (Pilot in Nigeria) LicenseWeb Authorities

16. How to benefit from this work in other O&G regions • International standards • Developed by POSC, Oil Companies and TE • Included in the ISO 15926 standard • Project includes pilots and can be monitored by companies • Participating companies in the project are the major Oil Companies • Developed with regard to be a global standard and available for further extensions and regional deployment: • More definitions can be added to the standard • New data elements can be included in XML structure

17. Results & Experiences from the pilot • Recommendation from the OLF • OLF's Committee for Health, Safety and Operation (HSO) unanimous approved the recommendation to implement the "Daily Production Report system" on the Norwegian Continental Shelf in 2006.  The work on this system was initiated by Petoro and has been supported by 7-8 major operators on the NCS. The project group is planning to establish an implementation priority list.

18. Experiences from the Pilot • All companies were satisfied, both operators and partners • Stable and good performance • More data exposed to partners and onshore than earlier • Showed that all partner got the same data more expedient than earlier • Identified uncommon practice and procedures for data approval between companies and within team leaders within the same company • This resulted in a need more sophisticated re-run application • Identified some improvements areas in the XML schemas • Feedback already provided to and discussed with POSC

19. Current plans • Move the pilots into production • Prioritize new DPR implementations for Norwegian shelf • New field implementations for: • Exxon, Statoil, BP, Marathon, • Some implementations will be planned into 2007 • Establish an operational environment in TE and Customer sites • Establish a operational support group for customers
