ABSTRACT:
A method of installing a reception device in a cased well at an optimum depth for surveying a formation under production or a localized part thereof and a source of acoustic waves at the surface or in a well. A placing or setting of the device is achieved by associating a plurality of acoustic wave reception units with a tubing lowered into the well and by applying the respective units against the pipe casing of the well by arms and springs or by including the reception units in sondes which are mechanically uncoupled from the tubing during the stages of use, with the reception device being easily moved by displacing the tubing during, for example, interruptions in the production of effluents.
