Fisher’s research has focused in the areas of stratigraphy, sedimentology, oil and gas resource assessment and energy and environmental policy. In 1967 he introduced the concept of depositional systems—now a fundamental part of modern stratigraphy and sedimentology.
Dr. Fisher is past president of American Association of Petroleum Geologists, the Association of American State Geologists, and the American Geological Institute the American Institute of Professional Geologists, the Gulf Coast Association of Geological Societies, and the Austin Geological Society.
He has received the Powers Medal from the American Association of Petroleum Geologists, the Twenhofel Medal from SEPM (Society for Sedimentary Geology), the Campbell Medal from the American Geological Institute, the Parker Medal from the American Institute of Professional Geologists, the Boyd Medal from the Gulf Coast Association of Geological Societies, the Hedberg Medal for Energy from the Institute for the Study of Earth and Man, and the Milling Legendary Geoscientist Medal from the American Geological Institute, among numerous other awards.
Fisher holds a B.S. and D.Sc. Honoris Causa, from Southern Illinois University, a M.S. and Ph.D. in Geology from the University of Kansas, a D. Eng. Honoris Causa from the Colorado School of Mines, and a D. Sc. Honoris Causa from Flinders University. He received the Presidential Citation (equivalent to an honorary doctorate) from The University of Texas at Austin.
Fisher was elected to the U. S. National Academy of Engineering in 1994.
GCSSEPM Luncheon (Sponsorship Available)
Speaker: Dr. Maria Mutti (Professor at Universität Potsdam, Potsdam, Germany, and President, SEPM [Society for Sedimentary Geology])
Talk Title: Photozoan-Heterozoan Carbonate Systems: Evaluating Cenozoic and Mesozoic Examples
Date: Friday, November 3, 2017
Location: Salon M
Bio: Professor Dr. Maria Mutti is a Professor and Chair of Sedimentary Geology at the Institute of Earth and Environmental Sciences at the Universität Potsdam in Potsdam, Germany. Dr. Mutti is the President of SEPM (Society for Sedimentary Geology) for 2017-2018. She is an Italian citizen, and was educated in both Italy and the United States, obtaining her MSc. from the University of Wisconsin-Madison and her doctorate from the University of Milan, Italy. Her primary research interests are modern and ancient carbonate sedimentation, quantitative and applied sedimentology, outcrop and subsurface modeling, diagenesis and stable isotope geochemistry of carbonate rocks. Dr. Mutti has been very active as a consultant and researcher, and has held various offices in international scientific societies, including being the Vice-President of the IAS (International Association of Sedimentologists). She served SEPM as the Councilor for Sedimentology and International Councilor prior to being chosen President-Elect of SEPM in 2016.
Abstract: Modern carbonate systems are subdivided into Photozoan and Heterozoan assemblages, based on the environmental requirements of the biocalcifying organisms which produce carbonate sediments. Because biocalcification mechanisms and environmental requirements have changed through time, it becomes increasingly challenging to apply this differentiation to older carbonate systems. Selected examples from Cenozoic icehouse and Mesozoic greenhouse time intervals are discussed to highlight the effects of major limiting factors in the geological past and to highlight how differences in biogenic assemblages impact both stratigraphic architecture and diagenetic potential in carbonate systems of different ages.
Icehouse times are generally characterized by stronger temperature and nutrient gradients, with environments spanning the full spread of possible conditions. Times of climatic changeover are recorded by broad, community shifts from the Photozoan to Heterozoan-Photozoan transition. Greenhouse times, conversely, are characterized by gentler temperature gradients and biota suggest that mesotrophic conditions were more widespread. This translates to a higher chance to find an expanded occurrence of Heterozoan-Photozoan transitional settings in warmer waters and across a much larger spread of latitudes.
AAPG DPA Luncheon (Sponsorship Available)
Speaker: Dr. Thomas E. Ewing
Talk Title: Petroleum Provinces in Texas Through Time
Date: Friday, November 3, 2017
Location: Salon J
Bio: Dr. Thomas Ewing is a geoscientist with over 35 years of experience in hydrocarbon exploration and research. He is a Registered Professional Geoscientist in the State of Texas (#1320) and the State of Louisiana (#468) and an AAPG/DPA Certified Petroleum Geologist (#4538), and holds certification #1610 from SIPES.
He received a B.A. in Geology from the Colorado College (1975), an M.S. in Geochemistry from New Mexico Institute of Mining and Technology (1977), and a Ph.D. in Geological Sciences from the University of British Columbia (1981).
Dr. Ewing was a research geologist for four years at the Texas Bureau of Economic Geology in Austin, where he served as a co-author of the "Atlas of Texas Oil Reservoirs", and compiled the Tectonic Map of Texas. Since 1985 he has been an owner of Frontera Exploration Consultants, Inc., a San Antonio-based geoscience consulting company. He worked with Venus Oil and Venus Exploration from 1985 to 2005 as staff consultant and Senior Explorationist, playing a main role in its successful exploration in the Yegua Trend of the Gulf Coast Basin and elsewhere in Texas. Dr. Ewing has served in many offices in AAPG and its Divisions, Most recently, he completed service as Vice-President for Sections of AAPG (2012-14). He received Honorary Membership in the South Texas Geological Society in 2009, Honorary Membership in the GCAGS in 2010, AAPG Distinguished Service Award, and BEG Alumnus of the Year in 2011. He is currently serving as President of the GCAGS before its 2017 convention in San Antonio.
Tom has spoken extensively at local, regional, and national geological meetings and published over 75 papers and abstracts. Among other awards, he has received the AAPG Levorsen Award three times, twice in Gulf Coast Section and once in Southwest Section. He has written articles on Gulf Coast geology and hydrocarbons, the geology and tectonics of Texas, and history and urban geology of the San Antonio area. He wrote the popular guidebook “Landscapes, Water and Man: Geology and Man in the San Antonio Area” published by the South Texas Geological Society in 2008.
In 2016, Dr. Ewing completed "Texas Through Time", an illustrated book and website on the geologic history and earth resources of Texas published by the Bureau of Economic Geology. In his spare time, he directs a 60-voice German men’s chorus, the San Antonio Liederkranz.
Abstract: Texas hosts numerous basins that have been prolific hydrocarbon producers, and still host high levels of activity. A basinwide look at these petroleum systems, using the insights gleaned from the new publication "Texas Through Time", is interesting and instructive. We can compare and contrast the Gulf Coast / Gulf of Mexico basin complex and the West Texas basins, and think about how hydrocarbons are generated and preserved in Texas' varied environments.
