Microbiological and physicochemical treatment of oil to increase field resource extraction

Abstract

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.

Analysis of the causes of flooding of long-term deposits under conditions of high geological heterogeneity

“… The movement of the agent used in the reservoir pressure maintenance system to implement the oil displacement process through highly permeable channels obtained during prolonged selective exposure to the object area [10][11][12].  Development of deposits of useful hydrocarbons, the geological features of which consist in the presence of alternating zones with a pronounced volume of water and oil, which are in direct contact and mutual influence with each other.…”
