CURVES Keep original Mnemonic as CURVE NAME Curve Property Type– Curve Type: generic classifications
which helps user understand purpose and can be used to drive processing
Property Type – based on extending Schlumberger’s original classifications
Curve Type – a ‘short-form’ version of the above based on mnemonic tokens
Property Type and Curve Type map one-to-one DESCRIPTION: a text description of the curve
Curve Types provide an additional context for reducing visual clutter and ordering/structuring enquiries

Curve and Property Type AttributeExamples
Curve Type Property Type
Note on Curve Type Structure• Separator improves readability• Hierarchical structure - can set to level of detail required• Structure facilitates searching/listing• Can be treated as a single value (easy to use in existing systems)

Project Management
Phase 1 consists of:Definition
Phase
Delivery Stage 1
Delivery Stage 2
Delivery Stage 3
End of Phase 1
Dec-2000
3 delivery stages
1 definition phase tool lists and grouping attribute definitions and usages
tools grouped by stage and service company
service companies make initial classifications
service company classifications 'normalised'
TechCom, Steering Group approval and publication
EndAgenda
Lessons Learned
Things always take longerthan expected
Build on existing work – but need to balance ‘legacy’ effects
Main classification issuesare understood and solved
Difficult to get oil companyinvolvement/feedback
Is TechCom – Steering Groupsplit effective?
The project is deemed a success butuptake will be the real test
End
Success Factors
Need enthusiasm to keepProjects moving forward
AgendaEnd
Business Framework and Maintenance are very
important
Communicate results – but ittakes resources
Phase 2 DefinitionParticipation
Acquisition companies: their support is critical Undertake the bulk of the technical work Key to implementation in delivery systems Focus on technical details of acquisition process Baker and Schlumberger have already expressed an
interest Halliburton? Others?
Oil Companies Needed to provide a ‘reality-check’ on deliverables Focus on use of well-log data
End
Phase 2 DefinitionParticipation
Software Vendors Applications that make use of the standards
Data Vendors Standard presentation of products will help
customers Government Agencies
Use of standards in regional/national repositories will facilitate data sharing
End
Phase 2 Definition
Define target customers: Generalist
Tool-level standards Curve definitions for KEY products (Composites, CPIs)
Historical acquisition tools Dipmeter/Image tools Formation Pressure tools Core Data Deviation Data (survey and interpolated) Mud Log data VSP
End
Phase 2 Definition
Business and Project Management Sponsorship
Develop business case
Project Management structures
Timelines for deliverables
Open Spirit
End
Maintenance of Phase 1
Current maintenance is ‘self-policing’ Website can be updated by authorised service
company users Current standards are held as (an extendable) look-
up list Question:
Is this sufficient to prevent ‘standards creep’ due to Misapplication of existing standards Arbitrary addition of further classifications
If not, what is the alternative and is it cost-effective?
End
Phase 2 Definition
Maintenance Release ‘moderator’
Release Schedules
Long-term funding
End
Phase 2 Definition
Phase 2 Timing Phase 1 Stages were highly coupled Could deliver Stages more easily if coupling was
minimal: Older technology tools are unlikely to require much
additional technical input Processed and Interpreted products are not strongly
linked to tools Phase 2 is behind Phase 1 in terms of annual cycle.
Should optimise early deliverables before summer holiday season
