Microbiological and physicochemical treatment of oil to increase field resource extraction

It was shown that the use of a physicochemical microbiological composition (FCMC) revealed a slight change in the amount of sulphate-reducing bacteria. The mineralization and density of the fluid taken from production wells before and after injection of this composition almost did not changed. After the FCMC injection, the watering of the pilot site slowed down. The calculations showed that the accumulated additional oil production of the pilot site during the period under study will be 856 tons and is increasing. These initial results suggest further effective application of the technology to other similar facilities.
