Professor of Petroleum and Natural Gas Engineering

119 Hosler Building


Biographical Sketch: 

Russell T. Johns is the George E. Trimble Chair in Earth and Mineral Sciences. Prior to his current position, he served on the petroleum engineering faculty at The University of Texas at Austin from 1995 to 2010. He also has nine years of industrial experience as a petrophysical engineer with Shell Oil and as a consulting engineer for Colenco Power Consulting in Baden, Switzerland. He holds a BS degree in electrical engineering from Northwestern University and MS and PhD degrees in petroleum engineering from Stanford. His research interests include enhanced oil recovery, thermodynamics and phase behavior, unconventional gas engineering, multiphase flow in porous media, and well testing. In these areas he has published over 250 technical papers, reports, and books including a recent update of the classic enhanced oil recovery book Fundamentals of Enhanced Oil Recovery. In 2016 he received the International SPE award in reservoir description and dynamics (chemical and gas flooding). Dr. Johns received the SPE Ferguson medal in 1993 for his research on the combined condensing/vaporizing gas-drive process. He served as Co-Executive Editor for SPE Reservoir Evaluation and Engineering journal from 2002 – 2004. In 2009, he was awarded the SPE Distinguished Member award. He is currently an Associate Editor for the SPE Journal and director of the Enhanced Oil Flooding consortium in the EMS Energy Institute at Penn State University.


In addition to the courses he currently teaches at Penn State, Dr. Johns also has taught university courses in Advanced Well Testing, Petrophysics, Reservoir Engineering II (Waterflooding), Thermodynamics and Phase Behavior, Advanced Thermodynamics, Environmental Remediation, Flow in Porous Media, Engineering Design, Advanced Reservoir Engineering, and Enhanced Oil Recovery. He has also taught courses in Gas Flooding, Enhanced Oil Recovery, and Waterflooding to industry.
