Method for evaluating the damage to the structure of rock surrounding a well, comprising the following steps: injection into the rock, which is already saturated with a first fluid having a first viscosity, of an oil with higher viscosity than the first viscosity; recording the pressure of the injected oil as a function of time; and analysis of the change in the pressure of the injected oil in order to deduce the different-permeability regions present in the rock.
