Data Catalogue: Challenges and Experiences of Asset Acquisitions Sue Edwards Jennifer Morrison Frank Watkin Richard Wright 21 st June 2006 POSC Regional SIG Meeting - Aberdeen
Who are Canadian Natural Resources ? One of Canada’s largest producers of crude One of North America’s largest natural gas producers World Class Senior Independent Oil & Gas Exploration, Development & Production operator Sixth largest Independent Exploration & Production Company with international exposure Major Alberta Oil Sands Player with HORIZON Project
Who are CNR CNR International’s operations are focused in North Sea and offshore West Africa Bases in… Aberdeen, Scotland Abidjan, Cote d’Ivoire Libreville, Gabon International ?
Information Management at CNR International - Organisation Central Service Document Control – projects and operational Capture Archive Subscriptions, technical reference, ‘library’ Draughting and Cartography Issue and control of Business Procedures, Safety Cases etc Single point of contact for all record types
Information Management at CNR International - Tool Document Management System - Documentum Information delivery on intranet One catalogue with targeted searches Electronic - paper – seismic – core – samples Loan management Standard approach to classification In-house cataloguing Transmittal system for document control – full project history Offsite storage is box management only
CNR International – Significant Acquisitions Transfer of Operatorship December 2002 - Ninian and Murchison Kerr McGee Knowledge of asset through previous partner relationship September 2004 - TBlock (Tiffany Toni Thelma) and B-Block (Balmoral Glamis and Stirling) ENI No previous knowledge – new asset Acquisition based on a plan for development/expansion Everyone needs information - NOW!
Data Transfer Challenges Simultaneously: Deliver information to new ‘consumers’ A real challenge when no previous interest in the asset Transition ongoing projects Ensure change management processes are in place - they may not match! Continue to work with existing suppliers Effect the transfer a variety of record types UKOOA Best Practice Guidelines should help Ensure ‘completeness’ Approach based on our retention policy/schedule Integrate catalogues with own systems Deliver catalogue to users for self help
Challenges – Variety of Catalogues Catalogues in Applications Spreadsheets and word documents Handwritten None! Engineers lists of boxes, subsequently renumbered Data type specific lists Pallets and bags of drawings Microfiche Core listings CDA Catalogue quality is dependent on available Information Management resources
Challenges – Merging Catalogues Balancing act Easier to find if all in one place – one catalogue versus 100 spreadsheets but…… Without consistent properties search results can be very poor How much time have we got? If you want it now – live with what you’ve got If you want it next year – then we can work on the data Involves: Understanding the classification system Understanding the history of the data Mapping it to in-house classification Avoiding loss of information
The G&G World Givens: Standards in place A well name is a well name – only small permutations Records are static If previous owner has been diligent in meeting obligations to the dti then information is accessible through CDA. Normally separate catalogues for paper and electronic records Routine tasks Clean up inconsistent well names Clean up field names ‘Shoehorn’ catalogues for paper and electronic into one system.
Variations on a Well Name: Columba well 3/08-S53 3/08-S53 DTI Well name 3/08A-S53G&G name 3/08A-S53 [D3]G&G name 3/08A-S53/D3G&G name 3/08A-S53[DP3]Derivation on log/report 3/08a-S53Derivation on log/report 3/08A-D3Derivation on log/report 3/08A-DW3Derivation on log/report One name for consistent and reliable search results
The Topsides and Subsea World Its dynamic Equipment is constantly modified and upgraded History is important Changes must be tracked Lacks standards Variable classification and cataloguing, often limited resources Vendor practices vary Older is worse! Different project teams and methodologies Cataloguing often reflects why being done – not what Value is underestimated Inability to find topsides and subsea information costs money!
Topsides and Subsea – Change Management Scenarios Pre 1990 - manual – output hardcopy 1990 onwards manual during projects with electronic copy loaded at end of projects (by which time new projects and modifications started) Recent – electronic with ‘e workflow’ Issues Vendor numbering system is different to project numbering system is different to operator numbering system Changes of ownership triggered changes to document management Which system was maintained? Was it reflected across paper/sepia and microfiche? Know the history It’s critical to retrieval of documentation for support of ongoing maintenance and development work
Topsides and Subsea – Document Numbering Example Tiffany Vendor Numbering PO No – Document Type - Discipline Code - Accession no - Sheet No U0003 - D - M - 4001 - 00 Tiffany Project Numbering Project no - Area Code - Document Type - Discipline Code - Accession No - Sheet No E - 11 - T - S - 0010 - 00 Tiffany Operator Numbering Asset name - Discipline Code - Document type - Accession number TIF - O - MN – 0301 Impedes ability to locate information by document number component
Topsides and Subsea – T-BLOCK Engineering Change Management T-Block Revision Numbering Philosophy 0,A,BIssued For Approval/Comment C,D,E, etcIssued for Construction/Revised for Construction X,X1,X2, etc As Fabricated Y,Y1,Y2, etcAs Built by Project Group Z,Z1,Z2, etcAs Built by Operator Toni/Thelma - Rules not used consistently/did not apply A, B, C, D As Built P1 to P9Used for comment Check assumptions! What is the latest version?
Topsides and Subsea – Classification Mapping Catalogue ACatalogue BELECTRICAL ELECTRICAL – HVACELECTRICAL ELECTRICAL – TELECOMMUNICATIONSELECTRICAL ELECTRICAL – INSTRUMENTATION – FIRE & GAS - TELECOMMUNICATIONS ELECTRICAL HVAC – ELECTRICAL HVAC HVAC – FIRE AND GASHVAC HVAC – INSTRUMENTATIONHVAC HVAC - INSTRUMENTATION – ELECTRICALHVAC HVAC – MECHANICALHVAC FIRE AND GAS – ELECTRICALFIRE AND GAS FIRE AND GAS – HVACFIRE AND GAS FIRE AND GAS – INSTRUMENTATIONFIRE AND GAS FIRE AND GAS – TELECOMMUNICATIONSFIRE AND GAS You have to make assumptions without seeing the records!

Topsides and Subsea – Cataloguing Equipment Dresser Rand Compressor One on Murchison and one on Balmoral – Same piece of equipment Different companies - different project controls – different documentation packages – Same piece of equipment Murchison: 400 records - generic descriptors Balmoral:800 records – detailed descriptors Scenario - Gas leak threatens production Find a parts list or an exploded diagram for the seal cartridge ‘seal’ plus ‘compressor’ plus ‘gas’ (no results with cartridge) Balmoral: 16 original documents Murchison: no original documents; 13 documents recent documents reflecting modifications by CNR User must know history and adapt search queries
Technical Challenges – Catalogue import to DMS Mapping properties from one system to another No classification– have to work with keyword analysis Single page tif system to multipage tif Change management system/version structure Rules and assumptions must be checked or can end up with wrong version displayed as the latest Pick lists v free text Field lengths Different applications environments – integrated systems
Vision User asks one question - gets relevant answers ‘edocument control’ with change management standards across the industry Simple high level standard catalogue classification to support catalogue integration at A&D.. increasing business efficiency and shareholder value
