A method using microbial technology to enhance oil recovery and production of a single well has succeeded in United States, Former Soviet Union and Canada. Microbe Oil Recovery Technique is easy to implement, and won’t damage oil reservoir, influence quality of oil and hasn’t any contamination. It has property of low invest, quick return and high benefit.

Theory of Microbe Oil Recovery Technique: The microbes are screened and selected from natural environment, and degrade paraffin in oil by complicated metabolism to produce organic acid, organic solvent molecule and biological surfactant agent. These produced substances can lower solidifying point and viscous of oil, reduce content of heavy components, lower oil-water interfacial tension and improve fluidity of oil. These will improve production of a single well, enhance oil recovery and extend working cycle of wells.
