Application of MEOR (microbial-enhanced oil recovery) process in wells of Oil India Limilted

The objecitve is to enhance the production of oil wells. TERI in collaboration with the ISR (Institute of Reservoir Studies), ONGC, have jointly developed a thermophilic, barophilic anaerobic bacterial consortium for enhancing oil recovery in dead or abandoned oil wells. With the application of this thermophilic anaerobic bacterial consortium, 21% enhanced oil recovery from live oil-bearing core rocks was obtained under simulated conditions in selected oil wells in Gujarat oilfields. In the first phase of trials, MEOR (microbial-enhanced oil recovery) technology has already been implemented in 30 oil wells of ONGC and more than 5.5 million US $ value additional crude oil was recovered from these wells. TERI in collaboration with ISR, ONGC has now entered into the second phase of implementing this technology in OIL (Oil India Limited), to enhance the production of oil wells of OIL, Duliajan, Assam.
