Microbial enhanced oil recovery (MEOR) among other enhanced oil recovery (EOR) innovation is an important alternative approach for oil recovery when primary and secondary methods aren’t productive. The responsible factor for MEOR procedure is the microbes and their by-products like biosurfactants, biopolymers and so on, biosurfactants assume key jobs such as degradation of hydrocarbon pollutants in soil, removal of metals from soil surfaces, dispersion of inorganic minerals in mining and manufacturing processes and so on. This study is focused on the application of isolated bacteria for the production of biosurfactants. From the isolation result Bacillus Nealsonii was the identified microbe Raise (R) and it was used to for the production of biosurfactant, the broth was used as the nutrient source and kerosene was the carbon source. Then this biosurfactant was applied in the MEOR at room temperature (27°C) using a reservoir permeability tester equipment. The recovery process using this biosurfactant gave 68.42% of residual oil recovery after the primary and secondary oil recovery, thus these hyperthermophiles are good agents for MEOR.
