Arkady M. Aizenberg is senior scientific researcher at the Trofimuk Institute of Petroleum Geology and Geophysics of the Siberian Branch of the Russian Academy of Sciences in Novosibirsk. Since the early 1980s, he has been at the forefront of the development of an analytic description of seismic wavefields in 3D heterogeneous layered and block media. He introduced a concept of a tip-wave beam composed from reflected/transmitted waves and associated edge and tip waves. In the early 2000s, Aizenberg introduced the generalization of the Weyl spectral representation for wavefields propagating near curved interfaces in heterogeneous acoustic and elastic media. Aizenberg graduated from Novosibirsk State University in 1971 and received a Ph.D. in geophysics in 1994 from the Supreme Certifying Commission of the Russian Federation.

Edge and Tip Diffractions: Theory & Applications in Seismic Prospecting

In Edge and Tip Diffractions: Theory and Applications in Seismic Prospecting (SEG Geophysical Monograph Series No. 14), the theoretical framework of the edge and tip wave theory of diffractions has been elaborated from fundamental wave mechanics. Seismic diffractions are inevitable parts of the recorded wavefi eld scattered from complex structural settings and thus carry back to the surface information that can be exploited to enhance the resolution of details in the underground. The edge and tip wave theory of diffractions provides a physically sound and mathematical consistent method of computing diffraction phenomena in realistic geologic models. In this book, theoretical derivations are followed by their numerical implementation and application to real exploration problems. The book was written initially as lecture notes for an internal course in diffraction modeling at Norsk Hydro Research Center, Bergen, Norway, and later was used for a graduate course at Novosibirsk State University in Russia.
