Abstract
This invention relates to compositions and methods of microbial enhanced oil recovery using biochemical-producing microbes. In specific embodiments, the methods of the subject invention comprise applying a biosurfactant-producing bacteria and/or a growth by-product thereof to an oil-producing site. In preferred embodiments, the bacteria is a strain of Bacillus in spore form. In some embodiments, the methods further comprise applying the bacteria with a yeast fermentation product, an alkaline compound, a polymer, a non-biological surfactant, and/or one or more chelating agents. Advantageously, the subject invention can be useful for stimulating the flow of oil from a well, as well as dissolving scale present in an oil-bearing formation.
Claims (3)
1. A method for stimulating the flow of oil from an oil-bearing formation, wherein the method comprises applying to the formation a sophorolipid biosurfactant produced by Starmerella bombicola and a fermentation medium in which the sophorolipid was produced, said fermentation medium comprising inactive yeast cellular components; wherein said method further comprises applying to the formation ethylenediaminetetraacetic acid (EDTA) as a chelating agent; at least one solvent that is isopropyl alcohol or ethanol; and a C8-C18 ethoxylated alcohol.
2. The method of claim 1 , further comprising applying one or more non-biological surfactants to the formation in addition to the ethoxylated alcohol.
3. The method of claim 1 , further comprising applying citric acid and/or sodium citrate as chelating agents.
