Dissertação (Mestrado em Química) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2020.https://repositorio.ufrn.br/handle/123456789/32622This work studied polyester resin compositions for application in oil well plug and abandonment operations. Systems containing pure polyester resin and resin with mineral filler and thixotropic agent were prepared and tested. The resin compositions were characterized by infrared where characteristic bands of polyester and styrene monomers were identified in all systems and even with the addition of the thixotropic agent and mineral filler, there was no chemical interaction between the added solids and the resin. Compressive strength (RC), rheology and stability tests were performed. The pure polyester resin showed an RC value above 90 MPa for all curing times, a result 12 times above the minimum required for abandonment operations (7 MPa). The rheological parameters classify all systems as Newtonian fluids. The addition of 5% mineral filler, by mass of resin, decreased the apparent viscosity of the resin in all systems in which these concentrations were present and the system with the best results in all tests was the system with 0.1 thixotropic agent and 5% mineral filler. Based on the results presented, the polyester resin proved to be promising for application in buffering operations and abandonment of oil wells.Acesso AbertoTamponamento e abandonoMateriais alternativosResina poliéstermasterThesis
