Laboratory of Seismic dynamic analysis<div style="text-align:justify;"></div><div style="text-align:justify;">The laboratory originates from the Laboratory of Direct and Reverse Seismic Problems, founded by Sergei Vasilievich Goldin (1936-2007, Ph.D., since 1966, Doctor of Science in Physics since 1989, in 1991 was elected Corresponding Member of the RAS, in 1997-2004 - Director of the Institute of Geophysics of the SB RAS). It was established in 1970 as a laboratory of mathematical methods in geophysics for applying mathematical statistics methods to the problems of geology and geophysics. In the mid-1970s, S.V. Goldina shift in the direction of the development of the theory and algorithms of inverse kinematic seismic problems and multidimensional spectral analysis of seismic data. In the mid-1970s, the spectral-statistical method successfully developed in the laboratory (GM Mitrofanov). Together with the Siberian geophysical expedition of the Ministry of Oil and Gas Industry (SibGE MNP), a package of kinematic interpretation programs for complex 2D media (KING) was developed that provided an assessment of the structural and velocity parameters of layered inhomogeneous two-dimensional media models with curvilinear boundaries along the hodographs of reflected longitudinal and transverse waves Exchange, multiple and refracted waves). In the mid-80's. A package of three-dimensional kinematic interpretation of SPACE was developed. In 1985, S.V. Goldin organized a summer school-seminar for young professionals, which for many years became the forge of seismic personnel for various scientific and production organizations.</div><div style="text-align:justify;"><br></div><div style="text-align:justify;">In 1989, the laboratory changed its name to "the laboratory of direct and inverse seismic problems," GM became the head. Mitrofanov. In the early 1990s, S.V. Goldin was engaged in the development of the geometric theory of migration of seismic waves and seismic tomography. The equations describing the migration transformations associated with the continuation of the velocity and DMO (SB Fomel) were proposed. In the second half of the 1990s, methods for the dynamic analysis of seismic data began to develop in the laboratory: multi-wave AVO analysis (TV Nefedkina), Proni-filtering to study the attenuation and frequency composition of seismic signals (GM Mitrofanov). In the 2000s, methods of AVO analysis on the complex of longitudinal and exchange waves, for reflections from thin-layered packets, for anisotropic layers (TV Nefedkina), AVO inversion of supercritical reflections (LV Skopintsev), asymptotic methods Extrapolation of the field to the caustic shadow zone (AA Duchkov). In 2008 the head of the laboratory became IV. Kulakov, and seismic tomography was added to the research topic. At the same time, the diffraction group (KD Klem-Musatov, AM Aizenberg) merged with the theme of modeling seismic wave fields by the method of multiple imposition of end waves. In 2016, the engineering seismic group (Yu.I. Kolesnikov, KV Fedin) joined with the subject of applying a passive standing wave method for detecting and outlining heterogeneities of different types in the upper part of the section.</div><div style="text-align:justify;"><br></div><div style="text-align:justify;">In the laboratory, seven candidates were defended (GM Mitrofanov, AV Okolsky, LG Kiseleva, VG Chernyakov, TV Kurdyukova, AA Duchkov, SV Yaskevich) and 2 doctoral dissertations (SV Goldin, GM Mitrofanov). Pupils of the laboratory also received a PhD degree abroad (SB Fomel, LV Skopintseva). The laboratory provided scientific guidance and joint research with production organizations "Sibneftegeofizika", "Irkutskneftegeofizika", 4 candidate dissertations and 2 doctoral dissertations were defended (VS Chernyak, DI Sudvarg, VG Pashkov, А.P. Sysoev).</div><p style="text-align:justify;"><br></p>Laboratory of Seismic dynamic analysisLaboratory of Seismic dynamic analysis
