- loading the at least one seismic data volume relating to the subsurface to data storage in communication with a processor, said processor performing;
unbiased sampling on at least one portion of the at least one seismic data volume to obtain at least one plurality of initial traces;
computing at least one plurality of samples along the at least one plurality of initial traces, wherein each of the at least one plurality of samples is defined by a position within a three dimensional lattice;
identifying at least one genotype for the at least one plurality of samples;
identifying at least one plurality of fit individuals by applying the at least one genotype to the at least one three dimensional seismic data volume;
creating at least one merged genotype using the at least one plurality of fit individuals in combination with the at least one plurality of samples; and
identifying at least one geopopulation that defines the geological features or the reservoir features of the subsurface formation by applying the at least one merged genotype to the at least one three dimensional seismic data volume.

Abstract
A seismic data analysis method including: loading at least one seismic data volume to a database, performing unbiased sampling on a portion of the seismic data volume to obtain a plurality of unbiased sampling traces, selecting a plurality of trace positions from the unbiased sampling traces, computing a plurality of samples, identifying a first set of wavelets using the samples, computing at least one genotype, creating at least two subpopulations by applying the genotype to the seismic data volume, analyzing the subpopulations for fitness to identify at least one fit population, forming a merged subpopulation by mapping similarities in the first set of wavelets, computing a second sample by identifying a second set of wavelets, creating a mutated subpopulation by applying the genotype to the second sample, and inserting the mutated subpopulation into the seismic data volume to create a geopopulation that defines geological parameters of a subsurface formation.
