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
• 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
• 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
proliferatingAll of which aim to get the job done faster, better,
with reduced cost, risk and uncertainty.
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
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
Assessment Criteria
• Impact indicators– Number of API processes
affected– 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.
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

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
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 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
