Efeito do controle da mobilidade e da redução da tensão interfacial no fator de recuperação do óleo : uma abordagem experimental

Abstract

Concern over the decline in oil production over time has led to the search for new alternatives to increase the oil recovery factor. The present work analyzed the displacement of oil retained in a porous medium in a pressurized environment, by means of the injection of three fluids: water, glycerin solution and sodium dodecyl sulfate (SDS) surfactant solution, three flows. The average result obtained for the conventional method (water injection) was in agreement with the values found in the literature (40.74%), guaranteeing the credibility of the experimental bench. The mean recovery percentage for the EOR (glycerol solution and surfactant solution) methods was approximately 20% greater than the conventional method. When analyzing the injection flows, it was concluded that lower flow rates generate higher recovery factor, but with longer times.
