Abstract
In this study, methane-producing bacteria were cultivated from fish waste and sugarcane
bagasse and then introduced into crude oil samples to enhance their rheological
characteristics. Crude oil's complex hydrocarbon composition poses challenges in
extraction, transportation and refining due to unpredictable physical traits like
high viscosity and pour point. This research pioneers an innovative, sustainable
strategy, exploring the potential of methane-producing bacteria to improve crude
oil flow. Tests conducted on crude oil samples from the North East India Oil Field
involved growing bacteria under specific conditions and meticulously characterizing
the oil's basic features. Methane-producing bacteria were then added to various
crude oil samples incubated optimally to boost metabolic activity. Employing a rheometer
and heat oven, the treated samples underwent thorough examination, measuring viscosity,
shear stress, pour point and relevant parameters. Results demonstrated the bacteria's
capability to reduce viscosity and shear stress while lowering the oil's pour point,
enhancing flow properties, especially at lower temperatures.
This study uncovers promising applications in the oil sector, presenting bacteria
as an eco-friendly remedy for crude oil viscosity, pour point and shear stress issues,
thus offering a sustainable approach to improving crude oil handling and transportation.
