Curtis Oldenburg is a Senior Scientist, Energy Resources Program Domain Lead, Geologic Carbon Sequestration Program Lead, and Editor in Chief of Greenhouse Gases: Science and Technology. Curt’s area of expertise is numerical model development and applications for coupled subsurface flow and transport processes. He has worked in geothermal reservoir modeling, vadose zone hydrology, and compressed gas energy storage. Curt’s focus for the last fifteen years has been on geologic carbon sequestration with emphasis on CO2 injection for enhanced gas recovery, and near-surface leakage and seepage including monitoring, detection, and risk-based frameworks for site selection and certification. Curt Oldenburg is a co-author of the textbook entitled Introduction to Carbon Capture and Sequestration.
