Course Description

This one day course will be of interest to those who have not previously run their own inversion projects, but who would like to understand, in a non mathematical sense, the components and parameters influencing inversion results. It is applicable to the usage of any inversion software package or inversion approach; and helpful for quality controlling inversions received from others.

Topics include:

  • The interpretation objectives of running either pre or post stack inversion
  • The similarities and differences between pre and post stack inversion
  • The importance of wavelets
  • What is the purpose of a low frequency model?
  • Comparison of an inversion run in the native depth domain rather than the traditional time domain
  • Methods for quality controlling any inversion.


Graham Carter has always worked with seismic data; initially as a seismic processor in Europe, Colombia and Canada, and more recently as a specialist in reservoir characterization software.  He finds the topic of inversion to be a fascinating blend of geophysics and geology that continues to evolve in it's capability to provide ever greater information from seismic. He has an Honours B.Sc. in Geology and is a registered professional geophysicist in Alberta.
