Advances in seismic recording instrumentation have made it possible to contemplate practical<br>acquisition scenarios with tens of thousands of active recording channels and many thousands<br>of Vibroseis source positions per day. The seismic survey designer is faced with the question<br>of how best to exploit this new operational capability to achieve ‘fit-for-purpose’ processed<br>seismic data, within project economics. Among the factors to be considered are the source<br>point density (# VP/km2), source point geometry (shot line and points intervals), and the level<br>and spectral content of source energy to be delivered at each source point. The latter point<br>and its relationship to the Signal-to-Environmental-Noise-Ratio (SENR) of the acquired data<br>is the subject of discussion proposed in this abstract.
