Multiphysics numerical model for the analyis of CO2 injection in carbonate rocks

Abstract

In recent years, it was noticed an increased interest on the development of multi-physics constitutive models to provide reactive chemical analysis of the impacts of CO2 injection in oil reservoirs. The movement was led by research groups interested in modelling Carbon Capture and Storage (CCS) and Enhanced Oil Recovery (EOR). Given the rise in global temperature, it was detected that carbon dioxide plays an important role in global warming, contributing to more than 70% of gases of greenhouse effect, with residence time of over 100 years. According to Kyoto protocol, the signatory countries have defined commitments to limit greenhouse emissions. To accomplish the carbon reduction targets, it was created the Clean Development Mechanism (CDM), where developed countries could invest in projects to reduce greenhouse emission in developing countries, being these reductions accounted for carbon credits.
