About the Editors

Timothy C. Coburn is Professor of Statistics at Abilene Christian University in Abilene, Texas, where he teaches coursesin applied statistics, information and decision support systems, and knowledge management. He holds a Ph.D. in statistics from Oklahoma State University. Along with his teaching duties, Coburn is actively engaged in statistical consulting and applied research across several segments of the energy complex, including petroleum resource estimation, subsurface characterization, energy economicsand market analysis, development of alternative transportation fuels, and environmental restoration. He has also served as Visiting Professor/Researcher in the Mathematical Geology Group at the Kansas Geological Survey in Lawrence, Kansas; the Eastern Energy Resources Division of the U.S. Geological Survey in Reston, Virginia; and the Energy and Environment Division at Sandia National Laboratory in Albuquerque, New Mexico.
    Prior to beginning his tenure at ACU, Coburn held a number of technical and administrative positions at Phillips Petroleum Company, Marathon Oil Company, and the National Renewable Energy Laboratory. At Phillips, he served as Research Statistician at the Bartlesville Research Center, and as a consuting statistician in the Western Division Drilling and Production Office in Denver, where he was assigned to the Prudhoe Bay equityredetermination on behalf of the Mobil-Phillips- Chevron consortium. At Marathon’s Petroleum Technology Centerin Littleton, Colorado, he was first employed as Senior Scientist in the Geophysical Technology Department andthen, for many years, as Supervisor of Quantitative Geosciences. He also served as Supervisor of Mapping and Database in the Exploration Services organization at Marathon’s Headquarters Office in Houston.
    Coburn is active in many professional and industry organizations, including the International Association for Mathematical Geology and the American Association of Petroleum Geologists. He was a long-time member of AAPG’s Publications and Geologic Computing committees, and he currently serves on the Editorial Board of Natural Resources Researchand as the Book Review Editor for Mathematical Geology.

Jeffrey M. Yarus is co-owner of Quantitative Geosciences, LLP, and lives in Houston, Texas. While attending the College of Wooster, he received a schol- arship to study geology for one year at the University of Durham, England, before earning his B.A. at Wooster. He earned his M.S. and Ph.D. degrees in geology from the University of South Carolina, where he refined his interests in computer mapping and numerical and statistical analysis. He joined Amoco Production Company in New Orleans, Louisiana, as a production geologist for the Gulf Coast Region. He left Amoco, to work as an independent for eight years on a variety of domestic basins in the Rockies, mid-continent, and Appalachian regions. He joined Marathon Oil Company’s Petroleum Technology Center in 1988, where he was instrumental in insti- tuting desktop computer mapping and geostatistical technology. Before co-founding Quantitative Geosciences with Richard Chambers, he held various managerial positions with GeoGraphix, Geomath, Roxar (formerly Smedvig Technologies), and Knowledge Reservoir. His professional activities include publishing, consulting, lecturing, and teaching applied training courses in reservoir characterization and geostatistical applications. Yarus currently serves as Adjunct Professor in the Petroleum Engineering Department at the University of Houston. He has also served as Adjunct Professor at the University of Colorado, Denver, and as Visiting Professor at the Colorado School of Mines. He is the current Chairman of the AAPG Reservoir Development Committee.

Richard L. Chambers is co-owner of Quantitative Geosciences, LLP, and lives in Bixby, Oklahoma. He earned B.A. and M.S. degrees in geology from the University of Montana, and then attended Michigan State University, earning a Ph.D. in geology with an emphasis on quantitative sedimentology and statistical applications. He worked for the Great Lakes Environmental Research Laboratory, National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce for eight years before joining Phillips Petroleum Company, where for eight years his activities included research in high-resolution P- and S-wave seismic imaging and developing exploration plays and lease acquisition strategies as a member of a regional basin studies team. In 1988, he joined the Amoco Production Company Research Center where he worked for nine years in various technical and management capacities related to the application of geostatistical methods for exploration and production problems. In 1997, he became a consultant providing training and geostatistical modeling expertise to the petroleum industry. His professional activities include publishing, consulting, lecturing, and teaching applied training courses in reservoir characterization and geostatistical applications. In late 2001, he co-founded Quantitative Geosciences, LLP, with Jeffrey Yarus, which has offices in Broken Arrow and Houston.
