WebThe invention claimed is: 1. A method of acquiring seismic survey data for a reservoir, the method comprising: providing one or more vibratory sources, each of the one or more vibratory sources being electric or hydraulic and providing a different seismic source signal pattern p (p 1, p 2 . . . p n), having a length t (t 1, t 2 . . . t n), each of the different … A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
