摘要
A method for configuring a multi-source and a hexa-source for acquiring first and second seismic datasets of a subsurface. The method includes selecting (1100) a number n of source arrays to create the multi-source; selecting (1102) a number m of sub-arrays for each source array, each sub-array having a plurality of source elements; imposing (1104) a distance D between any two adjacent source arrays of the multi-source; calculating (1106) a distance d between any two adjacent sub-arrays of a same source array so that bins associated with the first and second seismic datasets are interleaved; selecting (1108) source elements from at least six different sub-arrays of the n source arrays to create the hexa-source; and firing (1110) the multi-source to acquire the first dataset, and firing the hexa-source to acquire the second dataset.
