Fig. 3From: Microbial enhanced oil recovery through deep profile control using a conditional bacterial cellulose-producing strain derived from Enterobacter sp. FY-07Comparison of key parameters in core experiments. Core A, B, C and D correspond to core A, B, C and D in Tables 3, 4. Core A with high permeability and Core C with low permeability were connected in parallel to evaluate the plugging effect of Enterobacter sp. FY-0701, while Core B with high permeability and Core D with low permeability were connected in the same way to evaluate the plugging effect of Enterobacter sp. FY-07. Water flooding pressure, bacteria injection pressure and subsequent water flooding pressure were recorded during the experiment process; The plugging ratios of artificial cores were calculated by the Eq. (1)Back to article page
