Geophysical Standards Background
All branches of Geophysics involve iterative
processes, - requiring communication within and
between them
DataAcquisition
Planning Design
InformationManagement
DataProcessing
Interpretation Modelling
Standards for Content and Formatare needed for
effective communications

Indian Background to Geophysics SIG

• 1998 2004
• ONGCs EPINET Data Management Project
• Lessons learned getting 50 years of EP data
  under management
• It is not just about getting data into databases
• Data are worth little without supporting data,
  integrity, and quality assurance
• 2005 ONGC presented
• case for standards across Geophysical API
  activities cycle
• The lack of standards and best practices can
  impede the use of geophysical techniques,
  thereby reducing the value of those techniques to
  the organisation.
• Vision of multi-regional, global EP standards
  body
• Reiterated in 2006, and refined in 2007

6
Objectives of the Geophysics SIG

• As a representative of the community of creators
  and users of geophysical data and information
• To identify needs and requirements for open
  standards and improved work practices
• To collaboratively deliver, promote and deploy
  the standards and work practices across the life
  cycle of geophysical information

7
Drivers for Geophysical Standards

• Increasing number of uses of Geophysics
• More Exploration in mature and immature regions
• Applications in Field Development
• Applications in Smart Fields
• Optimising use of current techniques
• Enabling use of new techniques and technologies,
  in both seismic and information domains
• Increasing Data Volumes to be managed
• Various proprietary solutions already
  proliferating

All of which aim to get the job done faster,
better, with reduced cost, risk and uncertainty.
8
Initial Situation

• A list of gt60 Opportunities (areas for
  Improvement) from ONGC and other Indian EP
  Players
• These are from across the API (Acquisition,
  Processing, Interpretation) life cycle of
  geophysical data
• They probably satisfy the 8020 rule 80 of the
  higher value opportunities are already identified
• Companies joining in the future must be able to
  supplement the opportunity list if they add value
• Some of these opportunities are being used to
• Evolve and test our assessment process
• Promote and sell participation globally, beyond
  India

9
Visions

• It is possible to envisage a spectrum of targets
• From vocabularies for (SEG-format) Header or
  Trailers,
• To loose coupled work-flow integration, possibly
  web-based
• Our guiding lights must include
• Providing real Business Value to users and
  customers of Geophysics
• Establishing and adhering to relevant criteria on
  which to base our selections
• Providing specifications that can evolve to
  accommodate interoperability and technological
  change over at least one decade
• Plan to produce, pilot and test a few initial
  proposals

10
Assessment Criteria

• Impact indicators
• Number of API processesaffected
• Inaccuracy, uncertainty, risk,
• Loss of time
• Scale hours, days, weeks
• Value range 1 8 or 10
• Loss of data and/or metadata
• Quantity of impaired data
• Tasks needing Effort
• Specifying standard or improved work practice
• Implementing standard etc
• Deploying and promoting standard etc

Additional Approaches

• Collaboration with other Geophysical Standards
  Setting Organisations
• We will maintain awareness of and leverage
  existing and concurrent efforts by SEG, OGP,
  CSEG, OGC and others
• Focus on data transfer by XML messages loosely
  coupled via interfaces with existing applications
• We are aware of the perceived threat to existing
  software assets
• This approach is proving successful in
  near-real-time drilling (WITSML) and production
  optimisation (PRODML)
• Oilfield applications from Weatherford,
  Schlumberger, Kongsberg etc. are interoperating
  with Process Control apps from Invensys, OSISoft,
  AspenTech etc.

14
Deliverables

• Data exchange standards
• Usages conformant with SEG specifications
• Vocabularies of equipment items and
  configurations, version control, process history,
  etc left for User specification in SEG-D Revision
  3
• Data types not covered by SEG e.g. Velocity
• Work practice specifications
• Documented descriptions of improved work
  practices, in natural language and possibly an IT
  (UML or other?) model form
• At high and medium level, enabling adaptation as
  appropriate
• E.g. accommodate different practices for shooting
  new data c.f. acquiring spec data, or via trades
  or mergers

Geophysics SIG Road Map for 2008

• Assessment Work Group report and proposal is
  accepted by Energistics
• Proposes work on usage of SEG-D revision 3 to
  improve integration of seismic and positioning
  data in 2H2008
• Pause Seismic Headers and Velocity draft
  specifications
• Fit-for-use Indian SEG-Y header definition
  Velocity exchange format
• Expand participation internationally
• Oil companies, Seismic Co.s, Regulatory Agencies
• Work in full awareness of SEG Technical Standards
  Committee
• Set up SEG-D3 Usage Work Group
• Define objectives and use cases
• Obtain resources, produce and test pilot
  implementation(s)
• Promote, deploy and show benefit from improved
  work practices and standards
• Plan 2009 activities

17
Road Map for 2009 and beyond

• Continue approaches and activities as determined
  by business needs and support
• Review opportunity list and plan periodically
• Select 2 or 3 Opportunities for development,
  piloting and deployment each year

18
Conclusions

• The assessment indicates that significant
  opportunities exist in many organisations to
  reduce cycle-time to making business decisions
  based on geophysical information
• Active SIG membership is now being promoted to
  international EP and Service companies
• We have a good list of opportunities for
  improvements, many leveraging SEG standards
• Requirements for Velocity data and ONGC usage of
  SEG-Y headers are to be completed in June 2008
• SEG is being kept aware of these activities
