The distribution and activity of microorganisms in ground formations has been studied in order to assess their use and regulation during oil field exploitation. Experiments were performed on water-flooded oil fields of the Tatar ASSR and revealed some regularity in the distribution of aerobic and anaerobic microflora. Wells were opened after 3, 28 and 68 days after flooding with aerated water supplemented with nitrogen and phosphate salts. Activation of aerobes results in oxidation of residual oil (not released over 3 years of exploitation). The products (CO/sub 2/ fatty acids) of oxidation promote oil recovery. In the longer experiments anaerobic processes, especially methanogenesis from CO/sub 2/ were enhanced.
