Abstract
Method of performing a 3-D seismic survey using a plurality of vibroseis sources, and an array of seismic sensors arranged within a survey area. Each vibroseis source emits a distinctive acoustic signal and each seismic sensor of the array is in a continuous state of readiness to detect reflected acoustic signals. The method includes assigning vibroseis points (VPs) to each vibroseis source, moving each vibroseis source to assigned VPs where the vibroseis source emits an acoustic signal, recording the emission time of the acoustic signal by each vibroseis source at its assigned VPs together with the geographic position of the assigned VPs, continuously listening for reflected acoustic signals using the seismic sensors and recording a time domain record of the reflected acoustic signals received by each seismic sensor. Reflected acoustic signals associated with emission of an acoustic signal by a vibroseis source at an assigned VP are then determined.
