2. TietoEnator © 2003presentationPage 1 Daily production & activity report standardisation Meeting 5-6 april 2005

3. TietoEnator © 2003presentationPage 2 The Project  OLF initiative  All major operators and partners are participating –BP, ConocoPhillips, ENI, Exxon, Hydro, Petoro, Shell, Statoil, Total etc…  Purpose: –The Oil & Gas industry wants to coordinate and standardize the production & activity reporting on the Norwegian Continental Shelf

4. TietoEnator © 2003presentationPage 3 Background  Project started early in 2004  TietoEnator has been involved since september 2004  Our task / objectives: –Identify reporting demands –Describe solution –Define data –Reporting format / layout –Run Pilot

5. TietoEnator © 2003presentationPage 4 Reporting demands  Norwegian Petroleum act §24 §26 §27  NPD cover their needs with the information they receive from the operators –The information NPD receive vary from license to license / field to field. –NPD wants to be informed about the initiative and progress

6. TietoEnator © 2003presentationPage 5 Reporting demands ………..continue  Owner / Partner demands: –Easy access –Same dataset from license to license  Comparable data from field to field –Flexible solution regarding  What data needs to be reported – minimum of data reported  What data can be reported – maximum of data reported  No extra reporting in addition to current situation  Simple report structure –Easy aggregation of data –Easy data analysis

7. TietoEnator © 2003presentationPage 6 Main sources for datacollection  Daily production & activity reports from various operators and fields  Monthly reports in Copex format  EC allocation definitions  Schlumberger Oilfield glossary  API and ISO definitions  NPD Web pages  Petoro - Key performance indicator report (KPI)

8. TietoEnator © 2003presentationPage 7 How we worked Put all data into a spreadsheet and structured the data Compare reports Defined data items and worked with DNV to adjust to the ISO15926 standard Suggested a solution and report format

9. TietoEnator © 2003presentationPage 8 OLF Standard group - suggested name Abrivati on Data type/UNI T OLF Standard group - suggested definition ISO 15926 NAMEISO 15926 DEFINITIONS Daily Oil gross production Volume Sm3Total measured produced volume of oil on the installation including BS & W in 24 hours measured in standard cubic meter. DAILY GROSS OIL PRODUCTION VOLUME - STANDARD METRE CUBED A daily gross production volume, measured in standard cubic metre at 15 deg celsius. DAILY GROSS OIL PRODUCTION VOLUME A gross standard oil volume that is the daily (24 hour) gross oil production volume at a given date. GROSS STANDARD OIL VOLUME A liquid volume of oil including dissolved water, suspended water and suspended sediments but excluding free water and bottom sediment, calculated at standard conditions. MTD Oil gross production Volume Sm3Total cumulated measured produced volume of oil on the installation including BS & W in current month measured in standard cubic meter. MONTH TO-DATE ACCUMULATED GROSS OIL PRODUCTION VOLUME - STANDARD CUBIC METRE AT 15 DEG CELSIUS A month to-date accumulated gross oil production, measured in standard cubic metre at 15 deg celsius. MONTH TO-DATE ACCUMULATED GROSS OIL PRODUCTION VOLUME A gross standard oil volume that is the gross accumulated production volume of oil to-date in current month.

10. TietoEnator © 2003presentationPage 9 Decitions made in the project  Reporting will use XML format  Report will be divided into sections  Reporting shall be according to standard –Can report other data elements in addition to standard.  Data elements definitions will be a part of ISO 15926  Will use LicenseWeb to store XML reports and extract data

13. TietoEnator © 2003presentationPage 12 Pilot  Pilot from June - September  BP Valhall field  Statoil Åsgard field  Functionality included in pilottesting –Define XML as archive format in LicenseWeb –Retrieve reports online/ print –Export reports to Excel format for internal usage –Data extract based on time dimention weekly / monthly etc.. –Incorporate extract module i LicenseWeb
