FIELD: oil and gas production.
SUBSTANCE: procedure consists in recording information signals by their measured components during interval of time sufficient for recording statistically reliable noise signal in infra-low-frequency range. Recording is carried out by vertical components of information signals. Fourier-conversion of vertical components of information signals is performed by their first derivative. Seismic signals are recorded by measurements profile in points located at distance of 250 m from each other. Measurements profile of seismic signals is located at distance not over 1000 m from the point of stationary observation. Signals of gravitation field are recorded simultaneously with seismic signals. Simultaneously, there is determined conditional density, anomalies of potential density, acoustic speed, depth to bottom, dynamic height, potential temperature, Viyasel-Brent frequency, gradient of potential temperature, and gradient of salinity.
EFFECT: increased information value of obtained data at evaluation of hydrocarbon containing deposits.
