Abstract
Seismic pulses are emitted are emitted with consecutive time intervals that follow a pattern described by several Golomb rulers, wherein at least two of the Golomb rulers have at least four marks, such that pair-wise time intervals between seismic pulse emissions are different, to distinguish seismic reflections stemming from different seismic pulses and/or seismic sources from each other. This allows executing seismic surveys with several simultaneously operated seismic source arrays, thereby reducing the survey cost. In a marine environment the seismic sources may be air-gun arrays towed by one or more vessels, and the method can be also applied onshore.
