| Resumo: | Along the productive life of a reservoir, the natural energy decreases as the hydrocarbons and other compounds are produced, hampering the well productivity. Therefore, it is necessary to apply recovery methods to supplement the pressure or reduce viscous forces, increasing the production. These solutions are known as conventional and enhanced oil recovery methods (EOR). However, the some of these methods costs are not linear with profit curves, so researches have been seeking for methods to solve this impasse. Among the many possibilities, there is the use of industrial waste, such as glycerin from biodiesel or the use of surfactants as chemical assistant. Therefore, the aim of this study was to propose the use of two solutions composed by glycerin, distilled water and UNT L90 with concentrations of 2:1: CMC (GAT01) and 1:2: CMC (GAT02) in the enhanced oil recovery of a petroleum with 25,94 API gravity using a synthetic sandstone plug. Analyses to characterize each components of the system were performed. There were x-ray diffraction (DRX) and x-ray fluorescence (FRX) analyses of synthetic sandstone, specific gravity, viscosity, superficial tension and contact angle of the solutions GAT01 and GAT02, and analysis of specific gravity and viscosity of the petroleum from the Potiguar basin. After the tests and data treatment, it was found that the solution GAT01 reached a recovery factor of 4.53% and the solution GAT02 obtained a FR of 3.84%. The results of this work show a possibility to the development of a new advanced recovery system, since in both cases the solutions were good EOR alternatives for a medium API gravity oil reservoir. However, advanced studies involving the economic viability, with greater durability, using different pressure/temperature conditions, with more complex enhanced solutions and using the industrial residue of Biodiesel, crude glycerin, must be carried out with possibility to perform a small-scale test. |
