Abstract
Many studies on Microbial Improved Oil Recovery have demonstrated that bacteria have a positive effect<br>in regard to reduce the residual oil saturation. Possible mechanisms of IOR as a result of bacterial activity<br>are; interfacial tension reduction, change of wettability, gas production and conformance control through<br>selective blocking of the most permeable pore channels. Understanding which mechanisms allow bacteria<br>to increase oil recovery and how these mechanisms occur and interact is the key to better understand and<br>to get a clear insight into the complex MIOR processes.
