Day 0: Wednesday, July 20
10:00-3:00 Bring your laptop and get help with installing Madagascar
Tariq Alkhalifah, Sergey Fomel, Yang Liu, Jeffrey Shragge


Day 1: Thursday, July 21
8:50-9:00 Welcome (Yike Liu)
9:00-10:30 Introduction (Sergey Fomel)
10:30-10:45 break
10:45-12:15 Command-line usage, RSF file format, Vplot graphics
12:15-1:15 Lunch
1:15-2:45 Developing workflows using SCons
2:45-3:00 break
3:00-4:30 Writing reproducible papers (Tariq Alkhalifah)

Day 2: Friday, July 22
9:00-10:30 Wave-equation modeling and migration (Paul Sava)

The theoretical part of this module provides an overview of reverse-time imaging methodology applied to wavefield seismic data. The main technique discussed is reverse-time migration with emphasis on modern imaging conditions which enable migration velocity analysis and amplitude-versus-angle analysis. The applied part demonstrates this technique on a complex geologic model using Madagascar codes in a fully reproducible setup.

10:30-10:45 break
10:45-12:15 Seismic data processing example (Yang Liu)

Field data processing is an important test of integrality degree for open-source software and the final target for scientific research. We will use a 2-D field dataset to illustrate how Madagascar can set up a common seismic data processing workflow.

12:15-1:15 Lunch
1:15-2:45 Developing your own programs in Madagascar
2:45-3:00 break
3:00-4:30 Contributing to Madagascar (Sergey Fomel)

  • Tariq Alkhalifah is currently a Professor of Geophysics at KAUST in Saudi Arabia. He graduated with a PhD from Colorado School of Mines, Golden, Colorado, in 1996, and served afterwards as a Post Doc at Stanford University for 2 years sharing an office with Sergey Fomel. I used to be a devote SU Unix follower for most of my research carrier even as a Post Doc at Stanford (SEPlib people), but I have recently seen the light and converted to Madagascar.
  • Sergey Fomel has been working at the Bureau of Economic Geology at the University of Texas at Austin 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 Institute of Geophysics in Novosibirsk, Russia, and the Lawrence Berkeley National Laboratory. Sergey started work on Madagascar (at that time named RSF for Regularly Sampled Format) in 2003.
  • Yang Liu is currently an Associate Professor of Geophysics at College of Geo-exploration science and technology at Jilin University, China. He received a Ph.D. in Geophysics from Jilin University in 2006 and was a Postdoctoral fellow at Bureau of Economic Geology, The University of Texas at Austin from 2007 to 2010. His research focuses mainly on seismic data processing.
  • Xuxin Ma
  • Paul Sava is an Associate Professor of Geophysics and a member of the Center for Wave Phenomena at Colorado School of Mines. He holds an Engineering degree in Geophysics (1995) from the University of Bucharest, an M.Sc. (1998) and a Ph.D. (2004) in Geophysics from Stanford University where he was a member of the Stanford Exploration Project. His research interests are in wavefield seismic imaging, stochastic imaging and inversion, computational methods for wave propagation, numeric optimization and high performance computing.
  • Jeff Shragge is a Research Assistant Professor with the Centre for Petroleum Geoscience and CO2 Sequestration in the School of Earth and Environment at the University of Western Australia. He received his Ph.D. (Geophysics) in 2009 in seismic imaging with the Stanford Exploration Project at Stanford University. His research interests are in the fields of seismic imaging (migration, time-lapse imaging and velocity inversion) and high-performance computing (parallel computation, GPU programming).
