Reservoir characterization and complications for trapping mechanisms at Cranfield CO2 injection site
TL;DR: In this article, a variety of field data sets have been collected at the Cranfield CO2 injection and monitoring site of the Southeast Regional Carbon Sequestration Partnership (SECARB), where 3.54 million tons of CO2 had been injected by February 2012.

Snorri Gudbrandsson,Snorri Gudbrandsson,Domenik Wolff-Boenisch,Domenik Wolff-Boenisch,Sigurdur R. Gislason,Eric H. Oelkers,Eric H. Oelkers,Eric H. Oelkers +7 more
TL;DR: The steady-state, far-from-equilibrium dissolution rates of nine distinct plagioclases ranging in composition from An2 to An89 were measured in mixed flow reactors at 22 −± 2 −°C and pH from 2 to 11.5 as discussed by the authors.

Predicting long-term geochemical alteration of wellbore cement in a generic geological CO2 confinement site: tackling a difficult reactive transport modeling challenge
TL;DR: In this article, a set of numerical simulations that predict the evolution of fluid chemistry and mineral alteration in the cement of an idealized abandoned wellbore at the top of the Dogger aquifer in Paris Basin, France, where CO2 geological disposal is currently under consideration is presented.
Journal ArticleDOI
Limitations for brine acidification due to SO2 co-injection in geologic carbon sequestration
TL;DR: In this article, three different model scenarios were considered, including models that account for diffusion-limited release of SO2 from the CO2 phase, and three possible SO2 reactions: hydrolysis, oxidation, or disproportionation.

Predictive modeling of CO2 sequestration in deep saline sandstone reservoirs: Impacts of geochemical kinetics
Victor N. Balashov,George D. Guthrie,J. Alexandra Hakala,Christina L. Lopano,J. Donald Rimstidt,Susan L. Brantley +5 more
TL;DR: In this paper, the authors used a reactive diffusion model to investigate the fate of injected supercritical CO 2 fluid in the proposed baseline reservoir-plus-brine system, and they showed that the rate of CO 2 sequestration is sensitive to the mineral-water reaction kinetic constants between approximately 10 and 4000a.
