  • Methods for optimizing offset distribution of cross spread 3-D seismic surveys using variable shot line length
    Patent number: 8416640
    Abstract: A method for acquiring three-dimensional seismic data for sub-surface geologic features wherein a seismic source array is moved along a survey pattern having a plurality of source lines of unequal lengths that are substantially parallel to each other and intersect a receiver line. The survey pattern can be repeated in an overlapping and interleaved fashion to survey a larger area.
