Reactive Transport Modeling to Address the Issue of CO2 Geological Sequestration
Abstract One way for a reduction in the release of carbon dioxide (CO2) to the atmosphere is to inject CO2 into deep saline geological formations. Reactive transport modeling of hydrogeochemical processes is necessary to evaluate the behavior and...

Assessing seasonal changes in carbonate parameters across small spatial gradients in the Northeastern Chukchi Sea
Abstract Observations of the marine carbonate system were made in 2010 in the northeastern Chukchi Sea to constrain the seasonal progression of carbonate mineral saturation states (Ω) throughout the water column and determine the air–sea flux of...

Lidar sampling for large-area forest characterization: A review
Abstract The ability to use digital remotely sensed data for forest inventory is often limited by the nature of the measures, which, with the exception of multi-angular or stereo observations, are largely insensitive to vertically distributed...

Post-Injection monitoring of stored CO2 at the Nagaoka pilot site: 5 years time-lapse well logging results
Abstract Monitoring is the major challenge in CO2 geological sequestration. At the first Japanese pilot CO2 injection site (Nagaoka), CO2 was injected into a thin permeable zone at a depth of 1100 m and the total amount of injected CO2 was 10,400...

Determining CO2 /brine relative permeability and capillary threshold pressures for reservoir rocks and caprocks: Recommendations for development of standard laboratory protocols
Abstract Important parameters for the determination of fluid transport in reservoir rocks are capillary pressures and relative permeabilities for the CO2/brine system. These factors influence the plume migration, residual CO2 trapping and CO2...

Results from Sleipner gravity monitoring: Updated density and temperature distribution of the CO2 plume
Abstract To help monitor the evolution of stored CO2, we have made precision seafloor gravity measurements at 30 seafloor stations above the Sleipner CO2 plume in the years 2002, 2005 and 2009. Each epoch of gravity data has an intra-survey...

Geophysical methods for CO2 plume imaging: Comparison of performances
Abstract Geophysical methods are adequate for imaging the CO2 plume in order to follow its migration within the reservoir and possible leakages through the caprock formation. In particular, changes in density, seismic velocity or electrical...

Probability estimation of CO2 leakage through faults at geologic carbon sequestration sites
Abstract Leakage of CO2 and brine along faults at geologic carbon sequestration (GCS) sites is a primary concern for storage integrity. The focus of this study is on the estimation of the probability of leakage along faults or fractures. This...
