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

2. 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

3. 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

Contains definitions

Benefits
Definitions of concepts from important business processes in upstream oil and gas industry are available on Internet and can be used consistent by operators, service and engineering companies, and solution providers world wide. 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
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

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. Reporting of production data

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

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 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
