Curriculum Vitae
Biography
Sven Egenhoff, Ph.D., was born in Germany, and raised in Germany, Iran, and Argentina which helped shape his career path as a geologist. After obtaining his High-School Diploma in Buenos Aires, Argentina, he finished his Bachelor-equivalent degree at Technische Universität in Clausthal, northwestern Germany, and his Diploma (equivalent to a Master’s degree) at Ruprecht-Karls-Universität in Heidelberg, southern Germany. Sven obtained his Doctoral degree at Technische Universität Berlin in Berlin, Germany, on a topic focusing on the siliciclastic basin evolution of Ordovician sediments in southern Bolivia. After a 5.5 year lecturer position at Technische Universität Bergakademie Freiberg, southeastern Germany, he accepted an Assistant Professor position at Colorado State University where he stayed for 16 years and was successively promoted first to Associate, and then Full Professor. Since 2022, he is Director and Full Professor at the University of North Dakota. Sven is an expert in both shale and carbonate sedimentology applied to understanding conventional and unconventional reservoir deposition and diagenesis. He has twenty-four years of experience post-doctorate working worldwide on basic-scientific and hydrocarbon-related problems, mostly onshore Sweden, Norway, continental US (Bakken and Woodford), and Bolivia, as well as offshore UK (Kimmeridge Clay). Sven has trained over 400 undergraduate and graduate students in oil-related sedimentology and well-logs. He has graduated more than 25 students with M.S. or Ph.D. degrees since 2006 working on unconventional reservoirs in shales and mixed carbonate-siliciclastic systems, and has consulted or held research contracts with Hess, Marathon, and Noble Energy, among others.
