Abstract
The present invention relates to a method for enhanced hydrocarbon recovery in an underground reservoir rock comprising injecting an aqueous conditioning solution containing an alkaline agent, wherein the in-situ effects of the injection are determined by means of a flow simulation on a reservoir model discretized in cells, by taking into account the transport of the alkaline agent and without taking into account the transport of species referred to as intermediate species that result from the injection of the principal agent in aqueous solution, the intermediate species concentrations being determined analytically in each cell.
