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

Figure 8

Configuration for controlled-source interferometry by cross-correlation of perturbed fields; volume 𝕍 is enclosed by the source boundary 𝜕𝕊 and an additional boundary 𝜕𝔼 between overburden and target; 𝐱_𝑆 denotes a source location at 𝜕𝕊 and 𝐧_𝑆 is the unit normal vector of this surface; 𝐱_𝐸 denotes an additional source location at 𝜕𝔼 and 𝐧_𝐸 is the unit normal vector of this surface; heterogeneities between sources and receivers are referred to as “overburden,” whereas heterogeneities below the receivers are referred to as “target.”
