摘要

method for enhancing oil recovery from an oil reservoir, isolated microorganism, oil recovery enhancement composition and method. These are methods, microorganisms and compositions in which oil reservoirs are inoculated with microorganisms belonging to pseudomonas stutzeri and medium which includes an electron receptor. pseudomonas stutzeri proliferates in the oil reservoir to form clogged biofilms that reduce permeability in underground formations, thereby increasing purging efficiency and thereby enhancing oil recovery.
