Abstract
Discussions on the effects of anthropogenic emissions of greenhouse gas and their consequences on climate change have gained public notoriety in recent decades. The capture of carbon dioxide (CO2) from industrial sources and its subsequent storage in geological reservoirs has the potential to play an important role in reducing the harmful effects of the atmosphere CO2 emissions in the medium and long term. Based on their physical properties for applying geophysical techniques, studying and evaluating the behavior of rocks in the presence of CO2 has shown high relevance. This study deals with monitoring geological reservoirs in the presence of CO2 through the electrical resistivity method to estimate the electrical properties of the rocks involved, such as CO2 saturation and electrical resistivity of the medium. Simulations were performed on a four-layer synthetic model. The results validated the applicability of the electrical method in monitoring CO2 injection and leakage.
