Carbon Capture and Storage (CCS), also known as Carbon Capture and Sequestration, is the separation and capture of carbon dioxide (CO2) from the atmospheric emissions of industrial processes and its subsequent transport and permanent storage in deep underground rock formations.
By preventing the CO2 emissions from large-scale industrial facilities from entering the atmosphere, CCS is a powerful tool for combating climate change and reducing environmental impacts of oil and gas extraction. Geologic storage is the sequestration component of CCS by which the CO2 is permanently stored underground.
Secondary Enhanced Recovery
Secondary recovery is the recovery of oil or gas from a reservoir beyond the oil or gas that can be recovered by normal flowing and pumping operations under primary recovery scheme. Secondary recovery techniques involve injecting water, gas or other substances into the formation to maintain or enhance the reservoir pressure as a driving force for production of oil or gas to the surface.
Tertiary Enhanced Recovery
Tertiary recovery involves injecting other gases (such as carbon dioxide,) water soluble chemicals (such as polymers and surfactants) or heat (steam or hot water) to stimulate oil and gas flow to produce remaining fluids that were not extracted during primary or secondary recovery phases.
