Shale reservoirs are one of the world’s biggest assets and underexplored in many countries around the world. Shales were for the longest time thought of as massive but they aren’t. Unraveling the sedimentology of shale provided one glimpse into their diverse internal architecture, however, their diagenesis is most likely even more crucial. Shale diagenesis changes the behavior of the affected rocks and can be so severe that seemingly similar-looking shales behave completely differently when undergoing fracking.
This course will give an introduction to recognizing diagenetic changes in shales. It will run through the most important aspects that can be recognized on a macroscopic, microscopic, and sub-microscopic (SEM) level. With the knowledge acquired in this course, the participants can start working on evaluating diagenetic changes in shales. The course will constantly adapt and integrate current developments of shale diagenesis research.
The entire course will be taught online for now but a classroom version is planned for the future once the pandemic subsides.
and all who wish to develop a better understanding of the factors that control reservoir quality in mudrock (shale) reservoirs.
