Abstract

Summary

Seismic interferometry is used to redatum ocean-bottom nodes from a complex seafloor to the sea surface. The reciprocity equation of convolution type is applied to continue upward the sparsely distributed node. The interferometric redatuming of sparse data yields heavily aliased redatumed virtual gathers. To alleviate this problem, we modify the summation part of the reciprocity equation of convolution type to construct the virtual receivers by summing only the stationary contributions from adjacent nodes. The selection of an optimum summation aperture is determined by the stationary phase analysis. Tests on both synthetic and field data examples demonstrated the power of the proposed interferometric redatuming to reconstruct denser, and nonaliased virtual gathers.
