Role of geophysical techniques for carbon capture & storage
Introduction Geosequestration is often assigned as carbon capture and storage (CCS), carbon capture and geological storage (CCGS), carbon dioxide capture and storage, or clean-coal technology. Geological storage (Aquifer storage) Underground CO2 storage of any kind must take place in sedimentary rocks. Only they are porous enough to have storage capacity of interest. Storage of the CO2 in underground sites beneath a layer of impermeable rock (cap rock) which acts as a seal to prevent the CO2 from leaking out is the most popular option at present. There are three main types of proposed underground storage sites: Deep saline water-bearing formations (saline aquifers), Depleted oil and gas reservoirs , Oil reservoirs that may be used for CO2 Enhanced Oil Recovery (EOR), Deep coal seems containing methane (Enhanced Coal Bed Methane Recovery (ECBM) , Deep ocean storage. Methane Hydrate (white gold) Reservoirs - CO2 hydrates are more stable and if CO2 is injected into a methane hydrate reservoir, it will displace the methane hydrate by capturing the water from the methane hydrate and releasing the methane.
