2023 PESA WEBINAR SERIES: Understanding Internal Structures of Salt Domes – Working to Understand Risks for Cavern Storage Inside Salt
Tuesday, 30 May, 2023 @ 11:00 am - 12:00 pm (Australia/Perth time)
Free – $10.00
Guest Speaker(s): Michael Hudec (Bureau of Economic Geology, The University of Texas at Austin
Following a Ph.D. at the University of Wyoming, Mike Hudec worked 8 years for Exxon Production Research, then three years as a professor of structural geology at Baylor University. Then, in 2000 he moved to Austin to work with Martin Jackson in the Applied Geodynamics Laboratory (AGL) in the Bureau of Economic Geology, The University of Texas at Austin. In 2014 Mike became Principal Investigator of the group. His own own research centers on structural evolution of individual salt and shale structures, and on regional evolution of salt basins. He is author or co-author on well over 100 papers and two books, all on various aspects of salt and shale tectonics.

Understanding Internal Structures of Salt Domes – Working to Understand Risks for Cavern Storage Inside Salt
Presented by Michael Hudec (Bureau of Economic Geology, The University of Texas at Austin)
Abstract
Caverns in salt domes are currently being used for storage of petroleum, methane, carbon dioxide, and compressed air. Salt caverns are also the only proven solution for underground storage of hydrogen, and so may have an important role to play in the energy transition.
Key risks in salt-cavern stability and seal are the presence of shear zones and non-halite layers within the salt. In the ideal world, we could predict the location of such zones and layers, and then place our caverns to avoid them. Prediction requires understanding the origins of these features and how they are transported within salt domes. This presentation will summarize recent numerical modelling aimed at understanding how both weak and strong layers are transported within salt domes, and in how shear zones nucleate and may be predicted inside salt.
