  • Heavy oil recovery process using extremophile anaerobic indigenous microorganisms
    Patent number: 8895479
    Abstract: A process for increasing recovery of heavy oil with an API gravity equal to or greater than 10, contained in carbonate and/or sandstone porous media using extremophile (thermophilic, halotolerant and barotolerant) anaerobic indigenous microorganisms. The process involves nutrient injection to stimulate activity of extremophile anaerobic indigenous microorganisms at the well bottom, promoting the production of metabolites which improve oil mobility and increase oil recovery. Stimulation of extremophile anaerobic indigenous microorganisms and their metabolite production is conducted under anaerobic conditions at temperatures of 45 to 90° C., NaCl concentrations of 5,000 to 40,000 mg/L and pressures of 0.795 to 169 Kg/cm2 (11.3 to 2,400 psi). Heavy oils are recovered with API gravity equal to or greater than 10 degrees. The process enables up to 21% oil recovery in addition to the waterflooding process in porous media.
