Welcome to the SEAM Phase I-RPSEA Management Committee Community!

 

On 14 February 2007, the SEG Advanced Modeling (SEAM) Corporation was incorporated as a not-for-profit organization in the state of Oklahoma, with SEG as sole member, for the purpose of fiduciary, policy, and management oversight of the SEAM projects ("Phases"). SEAM is an industrial consortia dedicated to large-scale leading-edge geophysical numerical modeling.

The SEAM projects will provide the geophysical exploration community with geophysical model data for subsurface geological models at a level of complexity and size that cannot be practicably computed by any single company or small number of companies. A general introduction to the SEAM initiative can be found in TLE's June 2007 issue.

The SEAM mission is to advance the science and technology of applied geophysics through a cooperative industry effort focused on subsurface model construction and generation of synthetic data sets for geophysical problems of importance to the resource extraction industry. Data sets, after an initial two years of confidentiality, will enter the public domain.

The primary goals of SEAM are to:

  • design and generate synthetic model 3D and 2D seismic data
  • share the high cost effort of substantial model design and generation
  • provide a forum to discuss geophysical problems of interest
  • advance the art of modeling and computation
  • provide data sets for industry benchmarks and educational purposes

 The primary goals and accomplishments of SEAM Phase I are:

  • The numerical SEAM Earth Model, representative of a 60-block area of the deepwater Gulf of Mexico. This model has been constructed in a form that easily enables extension to other complex imaging challenges by adding the rock properties necessary for elastic, nonseismic, anisotropic, and viscoelastic.
  • Simulation of approximately 65,000 shot records, containing as many as 450,000 traces each, for an acoustic dataset.
  • Development and adoption of a data compression scheme.
  • Development of multiple "classic" data subsets for broad usage by the global research and academic communities.
  • The initiation of complementary geophysical simulations (e.g., CSEM, gravity, and magnetic modeling) over the SEAM Earth Model.
  • Establishment of a process for efficient storage and distribution of the data and the "classic" datasets.

 Phase I Participants                                                                                                   

The SEAM Phase I consortium consists of 24 companies from the hydrocarbon and geophysical exploration industries.  Each Participant is represented on theSEAM Phase I Management Committee.     

Phase I Vendors

Specific tasks are carried out by members of the Technical Management Committee and by selected vendors.  Vendors are selected through a rigorous, competitive bid and review process.  Phase I vendors include:

  • Tierra Geophysical LLC (subsequently Landmark)
  • Nexus Geosciences, Inc. (Subsequently WesternGeco)
  • Landmark
  • The Rice Inversion Project at Rice University
