  • Background to Geophysics SIG

  • Business Case

  • Some Visions

  • Current Approach and Plan

  • Conclusions

Geophysical standards background



Geophysical Standards: Background

  • All branches of Geophysics involve iterative processes,

    • - requiring communication within and between them

Planning &Design



Interpretation& Modelling


Standards for Content and Formatare needed for effective communications

Indian background to geophysics sig

Indian Background to Geophysics SIG

  • 1998 – 2004

    • ONGC’s EPINET Data Management Project

    • Lessons learned getting ~50 years of E&P 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 E&P standards body

  • Reiterated in 2006, and refined in 2007

Objectives of the geophysics sig

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

Drivers for geophysical standards

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.

Initial situation

Initial Situation

  • A list of >60 Opportunities (areas for Improvement) from ONGC and other Indian E&P Players

    • These are from across the ‘API’ (Acquisition, Processing, Interpretation) life cycle of geophysical data

    • They probably satisfy the 80:20 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



  • 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

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

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.



  • 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

Road map for 2009 and beyond

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



  • 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 E&P 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
