man of the AAPG House of Delegates, and has received numerous AAPG awards, including the Distinguished Service Award in 2002. He also served on the National Research Council committee that produced the 2002 report Geoscience Data and Collections: National Resources in Peril. In the last year he appeared and served as an advisor for the Swiss movie, A Crude Awakening; the National Geographic show, Gallon of Gas (part of the Man Made Series); and the VBS TV show LA’s Hidden Wells. This past summer he was interviewed by the Canadian Broadcasting Corporation and Spiegel Television (Germany) about oil development in the Los Angeles area. Mr. Clarke has published or presented more than 50 technical papers on topics that include computer mapping, sequence stratigraphy, horizontal drilling, structural geology, and reservoir evaluation, and he has been recognized by the Institute for the Advancement of Engineering as a fellow. He received his B.S. in geology from California State University, Northridge, with additional graduate study at California State University, Northridge, Los Angeles, and Long Beach.
Emmanuel Detournay is a professor of geomechanics in the Department of Civil Engineering at the University of Minnesota. He also holds a joint appointment with Commonwealth Scientific and Industrial Research Organisation Earth Science and Resource Engineering, where he leads the Drilling Mechanics Group. Prior to his current positions, he was senior research scientist at Schlumberger Cambridge Research in England. His expertise is in petroleum geomechanics with two current areas of focus: mechanics of hydraulic fractures and drilling mechanics. He has authored about 160 papers. He also has been awarded six U.S. patents and has received several scientific awards for his work. Dr. Detournay received his M.S. and Ph.D. in geoengineering from the University of Minnesota.
James H. Dieterich (NAS) is a distinguished professor of geophysics at the University of California, Riverside. His research has led to a new understanding of the Earth’s crust. He is an internationally renowned authority in rock mechanics, seismology, and volcanology. His pioneering studies in the theory, measurement, and application of frictional processes in rocks have had major implications for predicting fault instability and earthquake nucleation. His previous work on the rate- and state-dependent representation of fault constitutive properties is now being applied in modeling of seismicity, including aftershocks and triggering of earthquakes, and in inverse models that use earthquake rates to map stress changes in space and time. Dr. Dieterich recently launched a new effort to investigate fault slip and earthquake processes in geometrically complex fault systems, which includes development of large-scale quasidynamic simulations of seismicity in fault systems, and investigation of the physical interactions and stressing conditions that control system-level phenomena. Dr. Dieterich received his Ph.D. in geology and geophysics from Yale University.
