Production data reporting - standardisation WITSML meeting in Stavanger 18. Nov 2005

TietoEnator 14 000 employees Strong TietoEnator Oil & Gas commitment and focus Business skills and expertise World-class products Industry business solutions Full services range Present in Stavanger, Aberdeen, Groningen, Houston and Kuala Lumpur 250+ consultants dedicated to the Oil & Gas industry 2005-02-21

Background - Production reporting and Integrated operations in the North Sea region TietoEnator and Petoro initiated a common project for Performance and Production Management Standardisation and automation Focus on Production Integrated operations initiative Started by Norwegian Oil Industry Association's (OLF's) with (Shell, BP, Chevron, Exxon, Statoil, ConocoPhillips, Total, etc.) The overall program started 2001/2002 until at least 2008 Efficient real time data gathering Further develop the digital infrastructure on the Norwegian continental shelf Establish a common platform for data integration across field development phases, disciplines and companies based on international standards and new-technology These two initiatives led to the specific project on Production reporting run by OLF and TietoEnator 2005-02-21

Partner reporting evolution - Norwegian Continental Shelf Structured Hub-based Many to one One channel Automatic One format Enabling eOperations opportunities for partners (and operators) Unstructured Hub-based Many to one One channel Manual Various formats Unstructured point-to-point Many to many Various channels Manual Various formats 2005-02-21

This enable information sharing and efficient collaboration across disciplines and between operators, partners, authorities and their suppliers. 2005-02-21

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 2005-02-21

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 2005-02-21

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 2005-02-21

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 2005-02-21

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 Team 2005-02-21

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 – 2005-02-21

Reporting of production data Operator LicenseWeb/ AuthorityWeb Authorities/ partners 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-PROD) Possible to aggregate data Fully automated process All work performed by TietoEnator Production System XML-file XML processor XML- file Text- file LicenseWeb/ AuthorityWeb Daily prod data Partners Monthly prod data Produksjonsdata from EC Production or any production system able to deliver XML-files EC Production will include standard XML module for generating of standard production data LW/AW has an XML processor handling and storing XML files alongside with text base version in LW/AW. Partners/authorities can easily extract daily prodtuction data The XML format used is standardised in NCS and will be incorporated into the international ISO 15926 standard. Fully automisation is possible, without any manual interaction, except from deviations. Automisation all the way into auth/partners internal system is possible Due to standardisation, partners and auth can easily aggregate data from many/all fields to get summary, etc The process is supported bud the Norwegian Oil Association Authorities 2005-02-21

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 2005-02-21
