Abstract:
Microbial enhanced oil recovery (MEOR) is an alternative to EOR methods having advantages like low toxicity, bioequivalence, biodegradability, and economic feasibility for field implementation. The in-situ and ex-situ production of microbial metabolites and their application in laboratory scale study as well as in actual oil field condition, have their own merits and demerits, which require a multidisciplinary effort comprising of tools from Geophysics, Microbiology, Biochemistry, Soil Science, Chemical Engineering and Mechanical Engineering. Biosurfactants are amphipathic substances produced by a group of microbes like Bacillus sp., Pseudomonas sp., Alcaligenes sp., Achromobacrers sp., Burkholderia sp., Clostridium sp., Rhodococcus sp., etc., which play an imperative role in effecting efficient enhanced oil recovery through surface and interfacial tension (IFT) mitigation, wettability alteration, and viscosity reduction to increase permeability, etc. But, the main drawbacks to using biosurfactants of microbial origin in MEOR are their higher production cost and low production rates. Therefore, in this article, we primarily focused on different biotechnological approaches for incrementing biosurfactant production. Also, we have summarized the success story of biosurfactant based MEOR technology in laboratory scale as well as in the field scale highlighting the economics crude oil recovery.
