Abstract
The present invention relates to a process for the production of mineral oil from mineral oil deposits with large temperature gradients, in which, for increasing the mineral oil yield, highly permeable regions of the mineral oil formation are blocked by injecting formulations which, after being forced into the deposit, form highly viscous gels under the influence of the deposit temperature. A plurality of portions of the formulation which in each case can form gels at different temperatures and therefore result in very complete blocking of highly permeable regions of the formation are used.
