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