Professor Yan Kelai presided over the 23rd Geofriday academic report.
Teachers and students carefully listen to the presentation.
The 23rd GeoFriday Academic Day occurred online and offline from June 6th to June 16th. Professor Yan Kelai invited Professor Helge Hellevang, who delivered a report on "CO2-induced diagenesis - chemical and physical processes".
In recent years, greenhouse gas emission reduction has become one of the severe challenges faced by human society, and the geological storage of CO2 has always been regarded as the key technology to reduce CO2 emissions in the energy industry. To have a deeper scientific understanding of the physical and chemical processes such as CO2 dissolution and storage, numerical simulation calculation methods can reproduce the geological mineralisation and storage process and improve the feasibility and safety of CO2 storage. At the same time, PHREEQC diagenetic simulation software can also quantify various key diagenetic reactions, which helps promote the quantitative study of geological diagenetic events under the background of multidisciplinary integration. In the report, Professor Helge Hellevang introduced key diagenetic events, quantification of diagenetic reactions, introducing and applying PHREEQC diagenetic simulation software, etc. Combined with the examples of diagenetic events, it vividly showed teachers and students how to use software to conduct quantitative simulations and actively answered questions for teachers and students attending the meeting.
Dr Helge Hellevang graduated from the University of Bergen, Norway, and is currently a Professor and Head of the Department of Environmental Geosciences at the University of Oslo, Norway. He has long been engaged in diagenesis, fluid-rock interaction, CO2 geological storage and other aspects of research and is currently the deputy editor of Nature Scientific Reports. Basin Research, AAPG and other journals have published over 70 academic papers and co-published three monographs. Its results have a vast influence on the field of geogenic event simulation.
