Module 3. Ichnology

Course Details

ntil ten years ago, most geologists would write off entire sections of core as “bioturbated” and not take the time to describe ichnofacies or to think about the possible relationship between bioturbation and reservoir quality.

Thanks to the work of George Pemberton, Murray Gingras, James MacEachern, Tom De Keyser and others we now know that bioturbation can both increase and decrease reservoir quality. Therefore, if and when you do find bioturbation in your reservoirs it is your responsibility to understand what effect burrowing has had on quality.

Topics to be covered: How to measure bioturbation index, Psilonichnus ichnofacies, Skolithos ichnofacies, Cruziana ichnofacies, Zoophycos ichnofacies, brackish water vs normal salinity, shorefaces vs deltas, biogenically enhanced permeability.


• Geologists
• Geophysicists who wish to better seismic facies of fluvial, shallow and deep marine systems
• Petrophysicists
• Engineers who wish to develop a better understanding of the factors that control distribution, reservoir connectivity and compartmentalization in sandstone reservoirs

• Graduate Students (Masters or Doctorate) who wish to develop a better understanding of the petroleum industry and the importance of siliciclastic reservoirs


The course assumes no prior knowledge of siliciclastics therefore we also encourage non-geoscientists and graduate-students to enroll.
