Sergey Fomel

Sergey Fomel has been working at the Bureau of Economic Geology since 2002 and currently has an Associate Professor appointment, jointly with the Department of Geological Sciences. He received a Ph.D. in Geophysics from Stanford University in 2001 and worked previously at the Russian Institute of Geophysics, Schlumberger Geco-Prakla, and the Lawrence Berkeley National Laboratory. Sergey received the J. Clarence Karcher Award from the Society of Exploration Geophysicists (SEG) in 2001 and the Best Poster Presentation Award from SEG in 2007. He also shared the Honorable Mention Award from SEG with Paul Sava in 2004 for their Geophysics paper "Angle-domain common-image gathers by wavefield continuation methods" and the Lorand Eotvos Award from the European Association of Geoscientists and Engineers (EAGE) with Evgeny Landa and Tijmen-Jan Moser in 2007 for their Geophysical Prospecting paper "Path-integral seismic imaging". Sergey serves as an Associate Editor of Geophysics and devotes part of his time to developing "Madagascar", an open-source software package for geophysical data analysis.
 
lecture abstract

Lecture SF1: Seismic Data Patterns

Patterns are predictable parts of data. I explore patterns present in seismic reflection data and their use in extracting information about the Earth's subsurface. Geometrical patterns relate to the structure of geological horizons. Identifying them in the data allows us to separate the effect of reflection, caused by major horisons, from the effect of diffraction, caused by small objects such as faults, fractures, salt edges, and channels. Patterns related to data repeatability lead to efficient methods of seismic imaging. Both kinds of patterns are useful for data compression, which finds application in numerous data analysis tasks related to subsurface exploration and monitoring.
