Deghosting, Demultiple, and Deblurring in Controlled-Source Seismic Interferometry

Figure 13

Configuration for controlled-source interferometry by multidimensional deconvolution of perturbed fields; integration volume 𝕍 is enclosed by the free surface 𝜕𝔽 and receiver array 𝜕𝔸; 𝐱_𝑆 denotes a source location; 𝐱_𝐴 and 𝐱_𝐵 denote receiver locations at 𝜕𝔸 and 𝐧_𝐴 is the unit normal vector of the receiver array; 𝐧_𝐹 is the unit normal vector of the free surface; heterogeneities between sources and receivers are referred to as “overburden,” whereas heterogeneities below the receivers are referred to as “target.”
