Abstract: Methods, systems, and devices for the location of oil and gas deposits are disclosed. The technology is based on the recording of natural (i.e. not man-made) oscillations of oil and gas environments under the influence of the energy of resonances of the gravitational tides. The recording is performed by low-frequency geophones (0.1-10 Hz). The resonances are recorded, graphed, and analyzed. The time of the onset of the resonances of 14-day gravitational tides is pre-calculated by adding the tidal waves from the Moon, the Sun, and the stress wave arising in the Earth's lithosphere in connection with the periodic oscillation of the position of the barycenter of the Earth-Moon system. The calculation of the time of the onset allows for the prediction of optimal times for surveying according to the method of the present invention.
