Abstract:The goal of the study is to assess the feasibility of characterizing the caprock integrity by utilizing sampled helium (He) concentration in fluids and temperature measurement prior to CO2 injection. A series of simulations representing pre-CO2 injection phase was conducted to reveal the spatial distribution of groundwater, temperature, and He concentration under various geologic conditions of topographically driven basin. Then, their profiles in preinjection conditions were compared with dynamic signatures of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
