John McLennan has been an associate professor in the Department of Chemical Engineering at the University of Utah since October 2009 and a research professor in the same department since 2008; he also has been a Senior Research Scientist at the Energy & Geoscience Institute since 2008. McLennan has 30 years of experience in geomechanics with petroleum service and technology companies. He worked for Dowell Schlumberger for 9 years in its Denver, Tulsa, and Houston facilities; later, with TerraTek in Salt Lake City, Advantek International in Houston, and ASRC Energy Services in Anchorage, he worked on projects concerned with coalbed methane recovery, rock mechanical properties determinations, produced water, and drill cuttings reinjection, as well as casing design issues related to compaction. His recent work has focused on optimized gas production from shales and unconsolidated formations, fluid-rock interactions, and geothermal energy recovery. McLennan holds a PhD degree in civil engineering from the University of Toronto. See less
