Bacterial systems for selective plugging in secondary oil production
In order to improve the secondary recovery of petroleum from Lower Cretaceous bitumen and heavy oil deposits in Alberta, Canada, plugging studies of anaerobic bacteria, capable of the controlled production of slime, in situ were undertaken. Known cultures of L. mesenteroides (NRRL B512, B512F, B742 and B523) and 75 wild strains were tested in a model core flooding apparatus for their ability to produce stable, water insoluble polysaccharide slimes. Slime was not formed using glucose/fructose nutrient but was formed by the known cultures and four wild strains when sucrose nutrient media was used. However, wherein the polysaccharides slime produced by the wild strains was found to be water soluble dextran polymers and thus unstable, that produced by the known L. mesenteroides strains was water insoluble and stable. It is thus possible to produce a water stable core plug by injecting an appropriate strain of L. mesenteroides followed by an injection of sucrose solution.
