CO2 trapping and geo-electrical characterisation in the context of geological carbon sequestration

Carbon capture and sequestration (CCS) is the process whereby CO2 emission is captured primarily from a power plant, compressed, transported by pipeline or ship, and stored in geological formations on a geological timescale. The potential geological storage formations are deep saline aquifers, depleted oil and gas reservoirs, basalts, and deep un-mineable coal seams. While it has been argued that CCS mitigates the problem of CO2 emission, which presently causes abnormal weather conditions and global warming, the characteristic of the CO2 storage reservoir during CO2 injection is still not well-understood. This thesis uses experiments and modelling to define the two-phase flow of CO2 storage, aiming to answer two feasible questions. [Continues.]
