The feasibility of enhanced pore space utilization in CO storage reservoirs using an artificially emplaced Si-gel flow barrier.

Carbon capture and storage is a key technology to abate CO emissions. One of the challenges towards ensuring the efficiency and the security of CO storage in reservoirs, such as open saline aquifers, is the low pore space utilization. This study investigates the feasibility of using an artificial Si-gel barrier to enhance pore space utilisation in such reservoirs under variable geological conditions.
