Abstract: The Geological Geophysical Dialogue

By

Most modern exploration is done by multidisciplinary teams, wherein each member brings their own expertise to the table, but must also be able to understand the other members' contributions. In particular, each must be able to understand the jargon, the assumptions, and the approximations of the other, in order to hold a constructive dialogue. A lot of cross-disciplinary education is important for all members of the team.

The geologist is typically the expert in synthesis, whereas the geophysicist is typically more expert in Previous HitanalysisNext Hit. Because of this, geophysicists are the more able to win arguments by appealing to the Laws of Physics and to heavy computation. Here are some questions to ask them, in order to (help) keep them honest:

  • Which aspects of this seismic image do you believe, and which are artifacts of the processing and the acquisition?
  • Is this interpretation consistent with log-scale data?
  • Have you fully handled the 3D effects?
  • Have you considered the effects of seismic anisotropy?
  • Can we narrow the uncertainty here with other seismic data, for example, shear waves?

Questions like these, along with the robust Previous HitselfNext Hit-confidence needed to pose them, can go a long way toward helping the members of the team appreciate each other.
