Abstract:
A multistage process for producing mineral oil from mineral oil deposits by injecting aqueous flooding media into a mineral oil formation through injection boreholes and withdrawing the mineral oil through production boreholes, in which the mineral oil yield is increased by the use of microorganisms in combination with measures for blocking highly permeable zones of the mineral oil formation.
