Dissolved CO2 effect on the reactivity of the Hontomín reservoir rocks (limestone and sandstone)
- Geology
- 2015
A test site for CO2 geological storage is situated in Hontomin (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone (80-85%) and sandstone (15-20%). The reservoir rock…
CO2 mineral trapping comparison in different regions: predicted geochemical reactivity of the Precipice Sandstone reservoir and overlying Evergreen Formation
- GeologyPetroleum Geoscience
- 2021
Injected CO2 streams may have geochemical reactivity to different rock types in a CO2 storage complex depending on solubility and formation water chemistry. The Precipice Sandstone and Evergreen…

CO2 geological storage: hydro-chemo-mechanical analyses and implications
- Geology
- 2014
The injectivity of CO 2 and the integrity of the reservoir-caprock system are affected by CO 2 invasion, water-CO 2 -mineral reactions, and ensuing mineral dissolution and precipitation. We identify…
