WebOct 13, 2024 · OCO-2’s sampling strategy was designed to characterize CO 2 sources and sinks on regional to continental and ocean-basin scales, but the unprecedented kilometer-scale resolution and high sensitivity enables detection of CO 2 from natural and anthropogenic localized emission sources. OCO-2 captures seasonal, intra-urban, and …
WebSeismic data analysis proved that a CO2 plume as small as 5,000 tonnes can be detected in saline formations. A joint analysis of the seismic images for original and monitoring surveys observes that the plume images from post-injection surveys are very similar. WebAbstract. Recent advancements in experimental techniques allow sub-core-scale heterogeneities to be quantified in a high resolution. Based on the observations of heterogeneity distributions in natural core samples, we perform simulations to study the influence of small-scale heterogeneities on large-scale CO 2 migration during geological …
WebAug 17, 2024 · Dm-m-scale layered capillary heterogeneities can cause rapid field-scale plume migration, 100–200% faster than homogeneous and isotropic cases ... meter-kilometer scales. Carbon dioxide can migrate up to 200% faster in the presence of layered heterogeneities. These heterogeneities are ubiquitous in nature and provide an … WebGeologic storage is defined as the placement of CO 2 into a subsurface formation so that it will remain safely and permanently stored. The U.S. Department of Energy (DOE) is investigating five types of underground formations for geologic carbon storage: Saline formations Oil and natural gas reservoirs Unmineable coal seams Organic-rich shales
