A method for seismic surveying includes deploying a first seismic energy source at a plurality of locations along a source line. Locations are determined by, (i) setting a shot point at one end of the line, setting a minimum distance between shot points and setting a nominal shot point interval being greater than a Nyquist maximum spacing at a maximum spatial frequency to be evaluated in the subsurface area, (ii) calculating a maximum distance between shot points as a difference between twice the nominal shot point interval and the minimum distance, (iii) dividing a span between the maximum distance and the minimum distance into equally spaced samples, and choosing at random one of the equally spaced samples to calculate a shot point subsequent to the initial shot point; and (iv) setting the calculated shot point as the initial shot point and repeating (ii) and (iii) until the subsequent calculated shot point is within a predetermined distance of an opposed end of the first source line. Seismic receivers are deployed at proximate the subsurface area. The seismic energy source is actuated. Seismic signals are detected in response to energy imparted by the first seismic energy source by the receivers.
