Offshore injection of CO2 into volcanic sequences the North Atlantic Igneous Province may present a large-scale, permanent storage option through carbonate mineralization. To investigate this potential, onshore studies reservoir properties and reactivity subaerially erupted Faroe Islands Basalt Group have been conducted. Outcrop borehole samples reveal that lava flow crusts commonly contain vesicles filled with secondary minerals due to hydrothermal fluid circulation, however, unmineralized...
Offshore basalt flow sequences represent potential permanent CO2 sequestration sites along volcanic rifted margins. The International Ocean Discovery Program (IODP) Expedition 396 drilled six basement on the Vøring margin in 2021, recovering more than 350 m of basaltic cores and 15 granite cores. have been extensively analyzed following IODP shipboard procedures (e.g., velocity, density, porosity, magnetic susceptibility measurements). In addition, shore-based petrographic,...
Abstract Offshore CO 2 sequestration in basaltic formations of the North Atlantic Igneous Province may allow permanent storage large volumes through rapid carbonate mineralization. Characterizing internal architecture such reservoirs is key to assessing potential. In this study, six photogrammetry models and three boreholes on Faroe Islands have been used characterize lava sequence architectures as a direct analogue potential offshore sites. The studied are dominated by c. 5 50 m thick...
Basalt presents large potential reservoirs for carbon mineral storage. CO2 can react with the minerals in rock and precipitate carbonates, thereby becoming stored geological timescales. Experimental studies pilot injections Iceland US have shown feasibility of method. However, there are still open questions related to how where flows reacts basaltic reservoirs. Samples basalt from offshore mid-Norway containing naturally precipitated calcite therefore been studied as natural analogues such...
