Zusammenfassung:	Method for evaluating the damage to the structure of a rock (114) surrounding a well (110), comprising the following steps: - injecting into the rock (114), already saturated with a first fluid of a first viscosity, an oil of viscosity greater than the first viscosity, - recording the pressure of the injected oil as a function of time; - analysis of the change in the pressure of the injected oil in order to deduce the zones of different permeability present in the rock (114).
