Resumo: |
Carbon dioxide capture and storage in geological formations is an interesting technological solution for avoiding the emission of greenhouse gases from large industrial sources to the atmosphere. Also, it is largely employed in the oil & gas exploration industry, for enhanced oil recovery (EOR) operations. It is a known fact that injection of massive amounts of CO2 into geological reservoirs may lead to a series of alterations due to chemical and physical interactions with the fluid and minerals of the reservoir formation. Experimental and numerical models have been employed in many studies in the past decades, in order to investigate these effects on the geological environment. So far, most of these studies were focused in siliciclastic formations, whereas carbonate reservoirs, which are known to be much more chemically reactive when interacting with CO2, were less investigated. In this study, experiments were performed with rocks of carbonate composition found in typical oil and gas reservoirs with the purpose of evaluating the changes resulting from CO2-fluid-rock interactions under geological carbon storage conditions. |
