  • Patent number: 11709285
    Abstract: 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.
