RESUMO:

The change in the energy matrix is still far from the current reality, then, the geological storage appears as an alternative against the Global Warming, adopting the technique of capturing CO2 and CH4 before their emission into the atmosphere. They stand out as gas storage environments: the mature and abandoned oil fields. However, there is the necessity to develop sustainable cement pastes for the wells cementation with low permeability, in order to minimize the emission of these gases into the atmosphere. These pastes were developed with the addition of filler from the porcelain polishing waste and Water-borne polyurethane in order to analyze theirs effect on the reduction of the permeability in cement pastes for oil wells. To identify the best behavior, permeability, axial compressive strength, stability, density and carbonation, experiments were performed according to the Brazilian Association of Technical Standards (ABNT) and the American Petroleum Institute (API) specifications. The results obtained in the tests were satisfactory and it was verified that the addition of the Porcelain Polishing Waste and the Polyurethane contribute to the reduction of the permeability in cement pastes for oil wells.
