FIELD: mining. ^ SUBSTANCE: invention is related to the field of seismic survey of oil and gas deposits and may be used in survey in transition zones from dry land to shallow water and in river water area. Method for excitation of oscillations for seismic survey in transition zone and shallow water consists in the fact that excitation of oscillations is carried out by charges of explosive substance with weight of up to 0.1 kg, which are installed in wells with depth of 3-10 metres below water reservoir bottom, delivered through hollow augers. ^ EFFECT: higher validity of detection, accuracy, detail of definition and study of structure and physical properties of geological cut; provision of ecological purity of actions, integrity of water reservoir fauna.
