Geology

Characterization and Geocellular Modeling of Clastic Reservoirs

Geophysics

Understanding subsurface flow dynamics, e.g., CO2 plume migration and trapping, requires understanding a diverse set of geologic properties of the reservoir, from the pore scale to the basin scale. The uncertainty in site-specific geology stems from the inherent variation in rock types, depositional environments, and reservoir properties. Methodologies and tools are needed to represent reservoir properties at all scales to take into consideration small-scale features that could significantly affect storage integrity. Geologic attributes affecting reservoir behavior must be characterized. Robust geologic models are paramount to successfully predicting the distribution of CO2 within the storage reservoir.

Dustin Sweet

Dustin Sweet, PhD
Texas Tech University

Dr. Dustin E. Sweet holds a PhD (2009) in Geology from the University of Oklahoma and a MSc (2003) and a BSc (2000) in Geology from Boise State University. Upon completion of his PhD, Dr. Sweet worked as an exploration geologist at Chevron Energy Technology Company until he joined the faculty at Texas Tech University in the fall of 2011. During his time at Chevron, Dr. Sweet’s chief role was developing new plays and prospects in new venture opportunities, largely in West Africa. Dr. Sweet’s areas of expertise include process sedimentology, chemical weathering in soil profiles, and stratigraphy. He uses those skills to unravel climatic and tectonic history from the sedimentary record, predominantly within late Paleozoic basins in the United States and Quaternary strata on the Southern High Plains. He currently serves as leader of the Geology Theme for the Center for Geologic Storage of CO2, where he brings his sedimentologic and weathering skills to bear on understanding the character of the interval near the great unconformity in the mid-continent. He enjoys camping with his wife and three boys wherever late Paleozoic strata are exposed.

Steve Whittaker, PhD
University of Illinois, Urbana-Champaign

Dr. Steve Whittaker is the Director of Energy Research & Development at the Illinois State Geological Survey, which is a part of the Prairie Research Institute at the University of Illinois. He leads a team with wide-ranging research interests in efficiencies around subsurface resources, including carbon capture and storage. He was previously based in Perth, Australia, where he was Research Group Leader for Reservoir Dynamics with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), working on deploying carbon storage technology at the industrial scale in Australia and globally. Steve also serves as Chair of the TC265 committee developing ISO 27914, an international standard for geological storage of CO2. Previously, he was Principal Manager for Geologic Storage of CO2 at the Global CCS Institute in Canberra, Australia, and Chief Technology Manager at the Petroleum Technology Research Centre in Canada. In the latter position, he managed a program studying storage and monitoring of CO2 injected into a depleting oil field for enhanced oil recovery at Weyburn, Saskatchewan, which is among the world’s largest monitored CO2 injection sites. Steve is a geologist with a PhD from the University of Saskatchewan, Canada, and has worked in petroleum and carbon storage related fields for more than 20 years.
