ABSTRACT:
A method is disclosed for acquiring and processing logs obtained by a well-logging tool moved in a well, providing better discrimination between the discontinuities of the sub-soil oriented substantially in the same direction as the well and situated on each side thereof, and particularly in a substantially horizontal well. The method includes the displacement of the tool along the well and the provision of at least two series of signal transmission, reception and logging cycles, the position of the signal transmission and/or reception means relatively to the axis of the well being different from one series to another, so as to cause the distance from the transmission and/or reception means to the discontinuities on each side of the well to vary. Combining the logs from these series of cycles makes it possible to distinguish the reflections on the side of the well from which they come.
