Abstract
A seismic signal is created, processed and recorded and then analyzed to determine the nature of subterranean formations. A method of creating, processing and recording a seismic signal comprises the steps of creating a seismic signal; detecting the seismic signal at a first location during a selected time period simultaneously within a first frequency bandwidth and within a second frequency bandwidth, the second frequency bandwidth at least partially overlapping the first frequency bandwidth; creating a first band limited electrical signal representative of the seismic signal at the first location during a selected time period within the first frequency bandwidth; creating a second band limited electrical signal representative of the seismic signal at the first location during a selected time period within the second frequency bandwidth; combining the two band limited signals into a single signal having a frequency bandwidth including the first frequency bandwidth and the second frequency bandwidth; and displaying the single signal. The method according to the present invention permits optimal processing of each band limited signal, such that the displayed single signal possesses a relatively high signal-to-noise ratio and relatively accurately represents the original seismic signal.
