    Co2 Monitoring On the Continental Intercalare Aquifer at Krechba In Salah, Algeria
    (université Ghardaia, 2021) BEDJADJ, Amar
    Climate change partially due to emission of greenhouse gas is now a fact recognised by many scientists and governments. Carbon dioxide is responsible for over 60% of the "enhanced greenhouse effect”, the Carbon storage can take place in hydrocarbon deposits, oceans, coal seams, and saline aquifers. The In Salah Gaz project is joint venture between Sonatrach, British Petroleum and Staitol (Equinor) located in the central region of Algeria, is the first continental industrialscale CO2 storage project in the world. The natural gas produced from the area is rich in CO2 and this last is returned to the earth for geological storage. Almost million tonnes of CO2 have been injected since August 2004 till 2010 relating to relatively low permeability, 20 m thick, carboniferous filled with water. In order minimise the risks associated with CO2 storage in this area and understand their behaviour underground, it is necessary to study multiple techniques for monitoring and analysing CO2 storage for many years specially his effect on the underground waters, in our case is the Continental intercalare. Till now with the monitoring plan implemented there is no evidence of CO2 leakage in the aquifer, this will drove us to keep more focus on, and by involving some new methods on the monitoring plan.
