SCCS Spring Webinar
"Monitoring CO2 Storage Sites"
Jerry M. Harris & Abdullah Alshuhail
Prof Harris is the Cecil & Ida Green Professor of Geophysics at Stanford University, and a member of the Stanford Center for Carbon Storage. His research addresses a range of problems related to the physics and dynamics of seismic and electromagnetic waves in complex media, applied to the characterization and monitoring of petroleum and CO2 storage reservoirs.
Abdullah Alshuhail is a visiting professor in the Geophysics department at Stanford University. He is an assistant professor at King Abdullah University of Petroleum & Minerals.
Abstract: One of the main objectives of subsurface monitoring for Carbon Capture and Storage (CCS) projects is to assess safe containment of injected CO2 in subsurface geological reservoirs. We begin this presentation by summarizing the motivations, goals, and needs of subsurface monitoring of CO2 storage sites. We then review some documented natural and industrial analogs for CO2 leakage, and discuss how to characterize geological features such as faults and fractures that are expected to be dominant mechanisms of CO2 leakage. In the third and final part of the presentation, we review some of the challenges and opportunities of routine subsurface monitoring. Throughout the presentation, we discuss an integrated workflow that incorporates both conventional as well as new concepts for seismic subsurface monitoring.
