SC11 Seismic Anisotropy: Basic Theory and Applications in Exploration and Reservoir Characterization

Sponsored by: SEG

Thursday, 23 June – Friday, 24 June 2022, 11:00 a.m.–6:00 p.m.  |  

Who Should Attend

The course is designed for both graduate students majoring in applied geophysics and more experienced geophysicists working in research, technical service, or exploration. Attendees are expected to be familiar with the basics of seismic wave propagation and data processing.

Objectives

• Use appropriate parameterization for TI and orthorhombic models
• Apply linearized approximations to gain insight into anisotropic signatures
• Choose the most efficient method to model anisotropic wave propagation
• Recognize anisotropy-induced distortions in velocity analysis and imaging
• Evaluate the influence of anisotropy on kinematic and dynamic signatures
• Separate anisotropy and lateral velocity variation in NMO for layer-cake media
• Apply moveout and amplitude inversion to P-wave and multicomponent data
• Combine seismic data with borehole information to estimate TI parameters Predict the applicability of effective media theories for fracture models
• Use seismic attributes to characterize naturally fractured reservoirs

Course Content

Elastic anisotropy, widely recognized as a typical feature of sedimentary formations, has a strong influence on seismic velocities and amplitudes. For example, the difference between stacking and vertical velocity in anisotropic media most commonly is the reason for misties in time-to-depth conversion. This course provides the necessary background information regarding anisotropic wave propagation and discusses modeling, inversion, and processing of seismic reflection data in the presence of anisotropy.

Instructor

Ilya Tsvankin Colorado School of Mines

Ilya Tsvankin received his MS (1978) and PhD (1982) degrees in geophysics from Moscow State University in Russia. From 1978 to 1989 he worked at the Institute of Physics of the Earth in Moscow and was deputy head of the laboratory "Geophysics of Anisotropic Media." After moving to the U.S. in 1990, Ilya became a consultant to the Amoco Production Research Center in Tulsa. Since 1992 he has been on the faculty of Colorado School of Mines, where currently he is professor of geophysics and co-leader of the Center for Wave Phenomena. Ilya's research has focused on seismic modeling, inversion, and processing for anisotropic media, fracture characterization, nonlinear elasticity, and time-lapse seismic. For his pioneering work in seismic anisotropy, in 1996 he received the Virgil Kauffman Gold Medal Award from SEG. In 2011 Ilya was elected a Fellow of the Institute of Physics (IOP) in recognition of his contribution to the advancement of physics as a discipline and a profession. His monograph "Seismic signatures and analysis of reflection data in anisotropic media," published in 2001 and reprinted in 2005, is regarded as a major text in the field. A new book by Ilya and his long-time collaborator Vladimir Grechka, "Seismology of azimuthally anisotropic media and seismic fracture characterization," was published in 2011 by SEG. Ilya was also awarded SEG Honorary Membership in 2015. Since 2001, Ilya and Vladimir have been teaching a two-day course on anisotropy as part of the SEG Continuing Education Program.
