A method for determining the complex response of a permeable stratum at the bottom of a producing well, the well comprising a well head fitted with an outlet valve and the bottom of the well comprising a height-adjustable pressure and flow rate sensor, comprising the following steps: periodically altering the degree to which the outlet valve is open, and, while the alteration is in progress:—measuring the pressure and flow rate in the well at the top/bottom of the stratum for a certain number of periods of alteration, after a certain delay; and—measuring the pressure and the flow rate in the well at the bottom/top of the stratum for a certain number of periods of alteration, immediately after the positioning of the sensor.
