  • Alkaline microbial enhanced oil recovery
    Patent number: 10428302
    Abstract: A method of enhanced oil recovery that includes water-flooding an oil reservoir with an alkaline fluid or a fluid containing a compound toxic to indigenous microbes and inoculating the oil reservoir with a consortium comprising microbes that naturally are, or are engineered to be, obligatory alkaphilic, halo-alkaphilic or alkaline tolerant, and naturally are, or are engineered to be, deficient in their ability to utilize short chain hydrocarbons of 12 carbons or less but have the ability to convert hydrocarbons into fatty acids.
