worldwide and among them, crude oil plays a vital role. Oil recovery
is achieved using conventional primary and secondary recovery
methods. In-order to recover the remaining residual oil, technologies
like Enhanced Oil Recovery (EOR) are utilized which is also known
as tertiary recovery. Among EOR, Microbial enhanced oil recovery
(MEOR) is a technique which enables the improvement of oil
recovery by injection of bio-surfactant produced by microorganisms.
Bio-surfactant can retrieve unrecoverable oil from the cap rock which
is held by high capillary force. Bio-surfactant is a surface active agent
which can reduce the interfacial tension and reduce viscosity of oil
and thereby oil can be recovered to the surface as the mobility of the
oil is increased. Research in this area has shown promising results
besides the method is echo-friendly and cost effective compared with
other EOR techniques. In our research, on laboratory scale we
produced bio-surfactant using the strain Pseudomonas putida (MTCC
2467) and injected into designed simple sand packed column which
resembles actual petroleum reservoir. The experiment was conducted
in order to determine the efficiency of produced bio-surfactant in oil
recovery. The column was made of plastic material with 10 cm in
length. The diameter was 2.5 cm. The column was packed with fine
sand material. Sand was saturated with brine initially followed by oil
saturation. Water flooding followed by bio-surfactant injection was
done to determine the amount of oil recovered. Further, the injection
of bio-surfactant volume was varied and checked how effectively oil
recovery can be achieved. A comparative study was also done by
injecting Triton X 100 which is one of the chemical surfactant. Since,
bio-surfactant reduced surface and interfacial tension oil can be easily
recovered from the porous sand packed column.
