Abstract
A process for producing mineral oil from mineral oil deposits, in which the mineral oil yield is increased by blocking high-permeability regions of the mineral oil formation by injecting at least one formulation into the deposit, the formulation not being brought to a temperature at which the viscosity increases significantly until within the deposit, by injection of steam. The process can be used especially in the final stage of deposit development between water flooding and steam flooding of the deposits.
