System for attenuating high order free surface multiples from a seismic shot record using a genetic procedure

A computer program for producing a primaries-only reflection data set for processing seismic data recordings, the program stored on a computer readable media, comprising:

• instructions for generating a first generation of inverse wavelet (A(t)) and scale factor strings, each string in the generation representing a possible solution of A(t) and the scale factors for use in an equation to compute a primaries-only reflection data set;
• instructions for determining a fitness function value for each of the strings by evaluating a fitness function, wherein the fitness function comprises the total energy in the estimated primaries-only reflection data set;
• instructions for producing a succeeding generation of inverse wavelet A(t) and scale factor strings according to a variant of a genetic algorithm;
• instructions for repeating the step of determining a fitness function value for each of the strings in the succeeding generation;
• and
• instructions for identifying the string having a fitness function value meeting a specified criteria, wherein the identified string includes optimized estimates of the inverse wavelet A(t) and scale factors for use in determining the primaries-only reflection data set.
