Resumo:

With the production increase of its energy resources in the last decade, shale gas reservoirs have become an object of a technical feasibility study for geological carbon storage projects. In Brazil, Irati Formation stands out for its high potential for natural gas generation and its strategic location in the Paraná Basin due to its proximity to regions with higher concentrations of stationary carbon dioxide (CO2) emission sources. For initial estimates of the CO2 storage potential in this geological formation, this chapter presents the results of reservoir modelling and numerical simulations for an injector well project with a geological model based on Irati. For a geological unit with dimensions of 1,200 m X 600 m X 40 m, the storage capacity results are close to 800,000 tons of CO2, considering established safety parameters. The sensitivity analysis as a function of the maximization of the injection indicated the most significant influence of the reservoir’s pressure, thickness, and gas saturation for this evaluation.
