The present invention provides a microbial consortium containing three hyperthermophilic, barophilic, acidogenic anaerobic bacterial strains for , enhanced oil recovery from oil reservoirs where temperatures range from 70 ~C to 90 ~C. The said microbial consortium is unique in producing a variety of metabolic products mainly CO2, methane biosurfactant, volatile fatty acids , and alcohols in the presence of specially designed nutrient medium. These metabolic products increase sweep efficiency of crude oil from oil bearing poles of rock formation. The present invention also provides a process for enhancing the oil recovery byin situ application of the said microbial consortium
