John C. Horne
John is a sedimentologist/stratigrapher who has more than thirty-five years technical and management experience in the petroleum industry. This includes twenty-five years of energy consulting in Rocky Mountain and Gulf Coast basins. He has also participated in hydrocarbon exploration and exploitation projects in North America, South America, Europe, Africa, and Australia. This experience has provided a strong background in exploration, development, and data acquisition for energy-based companies. In 1981, John started the Energy Division of RPI International, Inc. Under his direction, RPI became an industry leader in multi-subscriber regional studies of hydrocarbon play trends. RPI completed more than thirty-five regional studies and basin-wide databases in the United States and Canada over a ten-year period. In 1990, John assisted Ecopetrol and ICP in establishing a regional study group in Colombia. Their first project was an assessment of the hydrocarbon potential of the Llanos Basin. More recently, he started a regional study group for Intera Information Technologies, Inc. (now Schlumberger-Holditch Reservoir Technologies). While there, he worked on projects in the United States, the North Sea, Mexico, Venezuela, Colombia, and Argentina.
John earned a Ph.D. in Geology from the University of Illinois and did a post-doctorate at Louisiana State University. He taught at the University of South Carolina and the Colorado School of Mines and authored numerous scientific publications on Paleozoic, Mesozoic, and Tertiary age strata in North America, South America, and Africa. John is a former AAPG Distinguished Lecturer and has taught industry courses in the applications of depositional modeling and sequence stratigraphy in hydrocarbon exploration and exploitation. These include AAPG field seminars on Ancient Clastics and the Sequence Stratigraphic Influence on Sandstone Reservoir Characteristics of Cretaceous Foreland Basin Deposits. He is a member of the American Association of Petroleum Geologists (AAPG), the Society of Economic Paleontologists and Mineralogists (SEPM), the Rocky Mountain Association of Geologists (RMAG), and the Wyoming Geological Association (WGA).
William C. Pearson
Bill is a potential field geophysicist with strong engineering and oceanography training. He has consulted in hundreds of exploration projects throughout the world, has written and sold advanced gravity, magnetic, processing and interpretation software for work stations and PC’s to major, independent, and foreign oil companies. He has taught dozens of industry schools on gravity/magnetic fundamentals and advanced computer techniques. Bill developed the popular and powerful gravity and magnetic 3D modeling software GMSYS3D in conjunction with GEOSOFT. This program computes both direct and inverse models with both vertically and horizontally varying rock properties. Bill has performed quality control, processing and interpretation of airborne gravity and/or full tensor gradient gravity surveys in South America, Africa, Canada and the U.S. He has participated as a successful team member in identifying petroleum prospects leading to discovery of fields ranging in size from less than one mmbo to over 500 mmbo. Bill has performed quality control and reprocessing of airborne gravity and full tensor gradient gravity surveys in South America, Africa, Canada and the U.S.
Bill earned a B.Ss. in Geophysical Engineering from the Colorado School of Mines and a Ph.Ds. in Oceanography from the University of Washington. He served as the Society of Exploration Geophysicists 2004-2005 Second Vice President. He served as Denver Geophysical Society’s Secretary, Vice President and then President in 2007 and is on the Board for 2009 as Prior Past President. He has been Co-Chairman of the Denver Geophysical Society/Rocky Mountain Association of Geologist annual 3-D Seismic Symposium for 15 years. Bill is also Co-Chairman of a new Innovative Geophysical Technologies Symposium in Denver in February, 2009. Bill is serving on the Technical Program Committee for the 2009 AAPG Convention in Denver. He completed eight years as a member and Chairman for 2001 for the SEG Scholarship Committee. Bill co-authored two patents for utilization of neural networks to map magnetic basement structure. He was along with Texaco was awarded the PTTC’s 1995 Technology Transfer Award for the neural network technology. Bill is a member of Denver International Petroleum Society, Rocky Mountain Association of Geologists, Geological Society of America, Tau Beta Pi, Sigma Gamma Epsilon, Colorado School of Mines Alumni Association. Dr. Pearson is currently serving on committees for the RMAG, and DGS.
Sandra L. Perry
Sandy is an exploration geologist specializing in satellite image analysis and photogeology. Beginning as a photogeologist with Cities Service Company, she worked on the Basin Analysis Team until returning for graduate work in 1983, where her emphasis turned to digital image processing and image analysis of satellite multispectral and airborne hyperspectral data. Her work closely integrates traditional structural and geomorphic interpretation with digital spectral compositional prediction and mineral modeling, all focused on exploration and field targeting. Most of Sandy’s 28-year career has been in consulting services for oil and gas, mineral, and geothermal exploration companies, having provided hundreds of projects covering six continents and contributing directly to the discovery of eight precious metal deposits in South America.
Sandy has a legacy of working directly with field geologists, especially those heading off into unmapped and remote terrain. Her technology approach focuses on identifying exploration target areas aimed at field investigation, geophysical/seismic survey planning, geochemical sampling, geologic mapping, and logistics. Author of scores of technical papers and professional presentations, Sandy has set up remote sensing/GIS laboratories around the world and conducted short courses emphasizing remote sensing and exploration in Chile, Argentina, Peru, Brazil, Mexico, Canada, Malaysia, Japan, Kazakhstan, and the former Soviet Union. Having completed a six-year research grant in compositional modeling using ASTER satellite imagery, she has been an active industry participant at NASA JPL and is currently a member of the NASA ASTER Science Team. Considered hands-on, Sandy pioneered the first successful application of high-quality image plotting using continuous-tone, ink-jet design with Hewlett-Packard from 1993-95 and also helped develop ENVI Image Processing Software, currently the most successful international image processing package.
Having perfected many approaches to alteration mapping for mineral exploration, Sandy’s current interest lies in identifying alteration mineralogy associated with hydrocarbon accumulation/migration, working on case histories in Kurdistan, Iraq. In addition, she refined structural/fracture analysis approaches for low-relief basin settings, where remote sensing interpretation tends to be most difficult and subjective. She also contributed to the use of satellite imagery for identifying and mapping oil seeps on water surfaces, using radar, Landsat, and ASTER satellite data. Her other personal career goal is to structurally interpret all major fold & thrust belts on Earth. So far, she has mapped the Eastern Cordillera of Colombia, the Ouachita Mountains, central and north Appalachians, Wyo/Utah Thrust Belt, Bolivian Tin Belt, Northern Zagros, Khorat Plateau of Thailand, Tien Shans of western China, and parts of the Indonesian Belt.
Sandy received her BSc degree in Geology (with honors) at Indiana State University and an MSc degree in Geology from the Colorado School of Mines. Her work experience included USGS Division of Geophysics, Barringer Geoservices, Barringer Labs, and Johnson Controls-World Services before going independent in 1991. She is a member of the following professional organizations: Sigma Gamma Epsilon (National Earth Science Honorary), Prospectors & Developers Assoc. of Canada, Colorado
Mining Association; Professional Geologist (State of Colorado), American Association of Petroleum Geologists, Rocky Mountain Association of Geologists, Society of Economic Geologists (SEG); former Trustee to SEG Foundation; member of NASA ASTER Science Team; NASA official contractor and co-investigator; Denver Regional Exploration Geoscientists; Geological Society of Nevada; Denver International Petroleum Society, and the Colorado School of Mines Alumni Association.
