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

Figure 2

Configuration for controlled-source interferometry by cross-correlation of full fields; volume 𝕍 is enclosed by the source array 𝜕𝕊 and an additional half sphere 𝜕𝕆 whose radius 𝑟→∞; 𝐱_𝑆 denotes a source location at 𝜕𝕊 and 𝐧_𝑆 is the unit normal vector of this surface; 𝐱_𝑂 denotes a source at 𝜕𝕆 and 𝐧_𝑂 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.”
