Agenda
4Well-Log Management Business Issues
- Data overload
- Too many curves - users cant find the important
data - Complex naming
- Both curve and LOG (collection of curves) names
are complex and changing at an ever increasing
rate - No consistency over time
- Confusing for experts and generalists alike
- No recognized central source for well-log naming
standards
End
5Data Overload
- Business Value
- Real Business Value is concentrated in a
relatively small number of data curves - filtered
views focus on high value data
Data Overload!
End
6Confusing Names
- CURVE Names
- Sonics DT1R, DT4P, DT4S, DT5, DTCR, DTMN, DTRP,
DTSD, DTSM, DTHC, DTHU - Densities RHOZ, NRHB, RHOM, HNRH, HRHO, RHOB,
HDEB, HROM - 712, 7121, 7122
- All Sonics DT, Densities RHOB
- GR_ED_001_AJB
- LOG/Tool Names
- GRAND SLAM
- DSI Vs DSST Vs SDT?
- PEX (HALS)
- HALS, HDLL, HDIL, HGNS, HNGS, HRDD, HRGD
- PROC1
- DAVE21
- 22MAY97
- COMP
- GEOL
- LOG refers to a collection of curves
- for example from a logging acquisition or
- interpretation process
End
7Clear NamesTool
Purpose to de-mystify proprietary and
esoteric naming systems
- Tool Names for acquisition data
- Keep full technical/marketing name
(information) - Generic Tool String Name from component Tool
Types (this is main LOG-level NAME that is
understandable to all and will be time-invariant - Specific Tool String Name created by
concatenating component tool names (information
and searchable) - (Other process stages)
- standard names for key composite and CPI data
sets
End
8Generic Tool Type AttributeExamples
Description
Tool Type
End
9Clear NamesCURVE
Curve Types provide an additional context for
reducing visual clutter and ordering/structuring
enquiries
- 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 Schlumbergers
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
End
10Curve and Property Type AttributeExamples
Property Type
Curve 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)
End
11Phase 1 Deliverables
- Standard CURVE level attributes and reference
values - Business Value
- Property and Curve Type
- Classification hierarchy
- Standard TOOL level attributes and reference
values - Generic, Technical and Marketing Tool Names
- Web-based delivery mechanism
End
12Phase 1 Project Management
- POSC Multi-company sponsored Project
- POSC Management
- Flare Consultants as Technical Contractor
- Project Management
- Steering Group
- Technical Committee
End
13Project Management
- 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
End
Agenda
14Lessons Learned
Build on existing work but need to balance
legacy effects
Things always take longer than expected
Main classification issues are understood and
solved
Is TechCom Steering Group split effective?
Difficult to get oil company involvement/feedback
The project is deemed a success but uptake will
be the real test
End
15Success Factors
Need enthusiasm to keep Projects moving forward
Business Framework and Maintenance are
very important
Communicate results but it takes resources
End
Agenda
16Phase 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
17Phase 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
18Phase 2 Definition
- Define target customers
- Generalist
- Tool-level standards
- Curve definitions for KEY products (Composites,
CPIs) only - Specialist
- Curve-level standards
End
19Phase 2 Definition
- Website and Communications
- Define user groups/functionality
- Define information content
- Develop Web interface
- Communicate Phase 1 results
- Communicate Phase 1 issues (non-consistency of
application of standards)
End
20Phase 2 Definition
- Implementation
- Involve application vendors
- A database demonstrator (also communication)
- DLIS and WellLogML
End
21Phase 2 Definition
- Additional Classifications
- Composited (joined) curves
- Generalist sets
- Interpreted curves
- Genaralist sets
- Commercial Packages
- Historical acquisition tools
- Dipmeter/Image tools
- Formation Pressure tools
- Core Data
- Deviation Data (survey and interpolated)
- Mud Log data
- VSP
End
22Phase 2 Definition
- Business and Project Management
- Sponsorship
- Develop business case
- Project Management structures
- Timelines for deliverables
- Open Spirit
End
23Maintenance 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
24Phase 2 Definition
- Maintenance
- Release moderator
- Release Schedules
- Long-term funding
End
25Phase 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
