Abstract
Method of generating a fold distribution for a number of seismic sources and seismic receivers, comprises: (a) selecting a Common Mid-Point location; (b) selecting a dip within a first predetermined range and a strike within a second predetermined range; (c) determining the fold for the selected dip and strike at the selected location; and (d) repeating the step (c) for a number of different dips within the first predetermined range and a number of strikes within the second predetermined range. Thus producing a Dip Movement Dip Coverage Spectrum for evaluating the quality of seismic data obtained from a given survey geometry. The invention obviates or mitigates the problems of the prior art by obtaining a true representation of the fold distribution.
