Abstract

Seismic interferometry is defined as the method to redatum sources and receivers where there only are receivers or sources, respectively. This can be done by correlation- or convolution-based methods. In this work we will present a new approach to reposition the seismic array over the earth’s surface to an arbitrary
datum at depth in two steps using deconvolutionbased methods: (a) redatuming of receivers and (b) redatuming of sources. This methodology accounts
for inhomogeneities in the overburden medium to remove anticausal events.
