man of the AAPG House of Delegates, and has received numerous AAPG awards, includ-
ing 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 Engi-
neering at the University of Minnesota. He also holds a joint appointment with Common-
wealth Scientific and Industrial Research Organisation Earth Science and Resource Engi-
neering, 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 trig-
gering 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.
