Who Should Attend

Intermediate Level
The intended audiences for this course are geoscientists-in-training, seismic data processors, petroleum geologists, seismic interpreters and operational geophysicists who are seeking to expand their knowledge base on modern concepts in geophysical data analysis.

Objectives

At the end of this course, attendees should be able to:

  • Suggest acquisition strategies to (a) broaden spectrum (both low and high) (b) reduce acquisition cost where appropriate (c) provide superior illumination and (d) improve conventional wave imaging using shear waves to highlight faults/fractures, low compressional wave impedance contrasts and gas-effected areas.
  • Advise and recommend key steps in data processing workflows.
  • Choose appropriate pre-stack depth migration algorithms to image expected dip range (e.g. Kirchhoff, Beam, RTM).
  • Advise on velocity-depth model building workflows (e.g. Grid Tomography or FWI).
  • Decide on the applicability of applying AVO and what elastic attributes to estimate.
  • Define optimal petrophysical parameters to be estimated using elastic attributes and an associated workflow including probability analysis if appropriate.

Course Content

This course covers a range of advanced data analysis topics including novel signal processing techniques, pre-stack depth migration, reservoir characterization, time lapse analysis and the road ahead.

The free on-line books by Jon F. Claerbout, material from SEG Wiki and papers published in Geophysics, The Leading Edge and SEG Expanded Abstracts are used to provide technical background for the course topics.

Each module is illustrated with examples, a list of publications and exercises.

Six modules are presented over three 4-hour days (virtual course). Each module lasts approximately 2 hours including break & exercises.

Robert J. Godfrey received a Bachelor of Applied Science degree in geological engineering from UBC in 1975 followed by a Ph.D. in geophysics in 1979 from Stanford University as a member of the Stanford Exploration Project founded by Jon Claerbout.

Following his graduation, he began his career with Mobil Field Research Lab in Dallas and then joined Digicon in London for 8 years where he worked in research and development. This was followed by a 25-year stint with Schlumberger where he worked in Calgary, Austin, London and Cairo, primarily in the fields of reservoir characterization and later in seismic monitoring. In 2015, he established Robert Godfrey Geophysics Inc., and is currently working as a geophysical consultant in seismic technology, geophysical education, and undertakes short-term field assignments. He is a member of the SEG and is a professional geoscientist in the province of Alberta.
