J. Frederick (Rick) Sarg received his Ph.D. (1976) in Carbonate Sedimentology and Stratigraphy from the University of Wisconsin-Madison. Rick has extensive petroleum exploration and production experience in research, supervisory, and operational assignments with Exxon (1976-90), Mobil Technology Company (1992-99) where he attained the position of Research Scientist, and with ExxonMobil Exploration (2000-05) where he was Stratigraphy Coordinator. Rick was a member of the exploration research group at Exxon that developed sequence stratigraphy, where his emphasis was on carbonate sequences. He has worldwide experience in integrated seismic-well-outcrop interpretation of carbonate sequences, and has authored or co-authored 33 papers on carbonate sedimentology and stratigraphy. Currently, Rick is a Research Professor at the Colorado School of Mines in the Department of Geology and Geological Engineering. Rick’s current projects include low-porosity, fractured carbonate reservoirs in Abu Dhabi; lacustrine carbonates and stratigraphy of the Green River Formation in Colorado, and the Bakken unconventional shale oil resource play.
