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-S53 G&G name

• 3/08A-S53 [D3] G&G name

• 3/08A-S53/D3 G&G name

• 3/08A-S53[DP3] Derivation on log/report

• 3/08a-S53 Derivation on log/report

• 3/08A-D3 Derivation on log/report

• 3/08A-DW3 Derivation 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,B Issued For Approval/Comment• C,D,E, etc Issued for Construction/Revised for Construction• X,X1,X2, etc As Fabricated• Y,Y1,Y2, etc As Built by Project Group• Z,Z1,Z2, etc As Built by Operator

Toni/Thelma - Rules not used consistently/did not apply

• A, B, C, D As Built• P1 to P9 Used for comment

Check assumptions!

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
