Next Generation 3D Imaging Models

Next Generation 3D Imaging Models

• SEG Research Committee (modeling
  sub-committee)

• Lewis Bartel
• Bee Bednar
• Biondo Biondi
• Joakim Blanch
• Arthur Cheng
• Richard Day
• Gregory Elbring
• Mike Fehler
• Leigh House
• Stewart Levin

Cooperative Motivation

• Shared numerical models have been advantageous
  (e.g. Marmousi, SEG 3D subsalt)

• New problems worth working on are of a size and
  cost not likely to be born by any one
  organization
• 3-D AVO analysis
• elastic inversion
• fracture detection
• prestack geometric attribute analysis
• shear wave splitting
• reservoir characterization
• OBC acquisition, illumination, and analysis
• multi-component data processing
• converted wave velocity analysis and imaging
• polarization filtering
• Q compensation
• 3-D prestack migration in rugged topography

Modeling Project Evolution

• Discussions among motivated colleagues (Stanford
  SEP etc.) 2004
• Ad-hoc meeting at SEG 2004 Denver (including
  EAGE)
• Biondi, Abriel, House, Bednar (and many others
  names available)
• Recognized rapid advancement in the past 10 years
  in sophistication of geophysical problems,
  modeling codes, compute speed, knowledge of
  properties and physics
• Concluded there is significant momentum for
  modeling project
• Recognized need for many models and many years to
  accomplish things in a step-wise fashion (e.g.
  elastic follows acoustic)
• Proposed a consortium driven by SEG research
  committee
• SEG research committee meeting 2005
• Agrees to be project owner
• Suggest major role for long term project manager
  (Bee Bednar nominated)
• Requests administrative assistance from SEG HQ

6
SEG executive committee meeting May 2005

• Request is to become non-profit SEG project
  with cost recovery. Run by project manager,
  responsible to consortium members, but under SEG
  legal controls.
• Why the SEG ??
• A Cooperative activity
• Less conflicts of interest than being driven by a
  university or an oil company
• Consistent with SEG charter to advance profession
• SEG can provide mechanism for contractual and
  fiscal controls
• SEG ownership provides evergreen intellectual
  interest
• Catalyst for geophysical progress and
  collaboration
• SEG can provide free data for educational
  purposes (donate to student sections, utility in
  SEG courses)
• opportunity for collaboration with AAPG/SPE in
  modeling geophysical response of important
  geology and fluid flow

Business proposal to be developed for distribution

• Operational structure
• Fees 30-50k / yr (initial 2 yr commitment)
• Data exclusive for paying members 2 years
• Data can be distributed to educational and
  non-profit organizations with
• consensus of paying members
• Open access after 2 years (recover copy and
  storage costs)
• SEG fiscal and contractual controls
• Project manager for planning, operations,
  communication and coordination
• Plans for modeling (2-5 years)
• Coordinate with Delft 3D physical model (subsalt)
• Expand numerical options in acquisition (Marine
  patch 3D, 3D VSP etc..)
• Build numerous small models to grow expertise in
  properties (anisotropy, elastic propagation, 4D
  production effects, complex stratigraphy .)
• Tests and benchmarks of modeling codes and
  compute resources
• Start-up planned for Fall 2005 (at or prior to
  SEG convention)

Start-up plan (Summer 2005)

• Goal Gather momentum before and at SEG
  convention to secure wide support for the project
  (e.g. sign up 20-25 paying companies).
• Before SEG
• Sign-up 6-8 Majors (Major Major oil company and
  Large contractor)
• gt Funding Members
• Assemble a model design working group
  collecting model components from Funding Members
• The Model Design Group should produce a
  conceptual design of the geological model before
  SEG.
• The group should meet 2-3 times before SEG (first
  tentative meeting on July 12th at CSM).
• Assemble a numerical algorithm and software
  working group to identify candidate for
  computations
• At SEG
• Present project during already scheduled SEG
  Post-Convention Workshop
• Involve SPE and AAPG in the process by inviting
  representative to SEG workshop
• After SEG
• Finalize contractual and legal framework
• Sign-up medium-size companies
• Try to get Grid-vendors (e.g. IBM, Sun) to
  support project
• START
