Claim 0:
1. A method for configuring a multi-source and a hexa- source for acquiring first and second seismic datasets to explore a subsurface with a shallow target resolution and with a deep target penetration, the method comprising:
selecting a number n of source arrays to create the multi-source;
selecting a number m of sub-arrays for each source array, each sub-array having a plurality of source elements;
imposing a distance D between any two adjacent source arrays of the multi- source;
selecting source elements from at least six different sub-arrays of the n source arrays to create the hexa-source;
calculating and imposing a distance d between any two adjacent sub-arrays of a same source array among the n source arrays so that first bins and second bins associated with the first and second seismic datasets acquired using the multi-source and the hexa-source, respectively, are interleaved; and
firing the multi-source to acquire the first dataset, and firing the hexa-source to acquire the second dataset,
wherein the first bins and the second bins are defined on a surface of the subsurface and include reflection points associated with traces of the first and of the second seismic dataset, respectively.
