Resumo:
CO2 injection and storage within the potential reservoirs depend on the geological/geochemical trapping mechanisms and the reservoir quality involving porosity, permeability and other flow unit factors. Core samples are not available for petrophysical evaluation of the rock units. Therefore, the reconceived expressions aided to predict the hydraulic unit in the shale and carbonate reservoirs concerning the CO2 storage capacity of the Irati Formation. The study presentes the average values of fl ow units in shale and carbonate units and their influences on the injection and storage of CO2. Low fl ow units may restrict the CO2 storage potential in shale, while water saturation (Sw)may aff ect the carbonate reservoirs. However, there are potentials for CO2 storage in the shale and carbonate rocks based on the abundance of the rock units within the study location, higher reservoir depths and proximity to CO2 emitting sources. The Irati Formation can also serve as a shale-carbonate hybrid geological reservoir for CO2 storage.
