Prior to joining Berkeley, he was a researcher at Shell Development, a research company managed for 20 years by M. King Hubbert of the Hubbert peaks. Patzek’s current research involves mathematical and numerical modeling of earth systems with emphasis on fluid flow in soils and rocks that can be hydrofractured. He is working on the thermodynamics and ecology of human survival, and food and energy supply for humanity. His current emphasis is the use of unconventional natural gas as a fuel bridge to the possible new energy supply schemes for the world. Patzek is a coauthor of over 300 papers and reports, and a book.
