Abstract

The biosurfactants are organic compounds which can be used as reducing the high interfacial tension between the oil and water contained in reservoir rocks, resulting in an increase in oil recovery rates. In order to evaluate the petroleum mobility in porous media, the characteristics of the medium and fluid were analyzed by simulating the actual conditions of pressure and temperature in the production of oil into a well to biosurfactant production and for analysis of oil recovery. As a result of analysis proposed for biosurfactant under study it was determined at the critical micelle concentration (CMC), with a value of 50 mg/L, showing stability against high temperature and high salt concentrations. The porous medium studied had a porosity of about 39.78 % and 124.37 mD permeability. In the oil recovery analysis results showed a partial recovery factor of 30.66 % and the total recovery factor of 50.47 % with the injection of biosurfactant. The results showed that the use of biosurfactant produced as substrate manipueira and the microorganism Bacillus subtilis can be used in advanced recovery process oil improved by microorganisms – MEOR.
