SEISMIC SURVEY METHOD Russian patent published in 2020 - IPC G01V1/26 

FIELD: geophysics.

SUBSTANCE: invention can be used in seismic survey operations. Claim describes a method in which data relating to output signals of first and second seismic sensors are received, including components, corresponding to detection of first and second seismic sensors of first and second seismic signals. At that propagation of the first seismic signal is directed from the first seismic sensor to the second seismic sensor, and the second seismic signal propagation is directed from the second seismic sensor to the first seismic sensor. Determining, relative to the first clock signal in the first seismic sensor, a first time instant, corresponding to arrival time of first seismic signal to first seismic sensor, and second time moment corresponding to time of arrival of second seismic signal to first seismic sensor. Determining, relative to the second clock signal in the second seismic sensor, the third time instant, corresponding to arrival time of first seismic signal to second seismic sensor, and fourth moment of time, corresponding to arrival time of second seismic signal to second seismic sensor. First clock signal is offset relative to the second clock signal using the first, second, third and fourth time instants.

EFFECT: technical result is high accuracy and information value of obtained data.
