Transport of Bacteria in Natural Core as Enhanced Oil Recovery Material

Abstract:

The effects of the bacterial cell size and flow velocity on the transport of concentrated suspensions of bacteria were experimentally investigated, and the bacteria retention mechanism was studied by observing bacterial distribution in natural cores. A lower reduction in permeability and a higher effluent bacterial concentration were obtained in the core flooding with the smaller cell size bacteria or at a higher flow velocity. The bacteria were easier to migrate through the porous rock directionally compared to the rigid solid particles owing to their organic flexibility. Bacteria retention occurred primarily at the inlet section of the natural core, and log-jam effect or pore bridging may be the dominant mechanism.
