Using microbiological technology to increase oil recovery for terrigenous oil deposits

Abstract

In this paper, the authors consider one of the widely used methods to increase the efficiency of flooding within the terrigenous reservoirs of the Volga-Ural oil and gas province - microbiological effects on the matrix of rocks to align the profile of pick-up and production. The process of the influence of metabolic products produced by microorganisms on the change in oil recovery coefficients over time has been comprehensively studied, as a result of which a significant increase in oil mobility has been established. The results of the measures and their main technical and economic indicators before the impact and after the operation are presented, on the basis of which it is recommended to use this technology to increase the efficiency of oil displacement in fields at the final stage of development as one of the alternative options for implementing high-quality energy resource management.
