Workshops Subsalt imaging challenges Organizers:
Chen Xiaohong
Alfred Liaw Location: BICC Conference Room 201B Due to the increasing demand of high-quality pre-stack depth imaging on subsalt exploration and development targets in the Gulf of Mexico and offshore Brazil, tremendous advances have been made in recent years in seismic acquisition and processing technology. This workshop will discuss recent advances, highlight outstanding issues, and identify possible R&D directions for meeting new subsalt imaging challenges. Examples of relevant contributions may cover wide azimuth acquisition, velocity tomography and model building, imaging and processing algorithms, and interpretations workflows for subsalt exploration targets. The advances in solving the subsalt imaging problems, made difficult by complicated salt geometries, high velocity contrasts, inadequate illuminations, and strong multiples, will also likely benefit applications in geological settings that are not subsalt.

Geophysical equipment Organizers:
Tao Zhifei
Shuki Ronen Location: BICC Conference Room 307 Thirty years ago seismic crews used typically 96 channels onshore and a single streamer. These days some crews have recorders with tens of thousands of channels, but, with few exceptions, are using the same types of hydrophones and geophones used 30 years ago. Progress on seismic sources has been even slower. Is this pattern going to continue with most progress being quantitative- and receiver-focused, or is now the time to focus on the sources and new types of receivers? Progress in electromagnetic methods (EM) has been strong in the last decade. Is the equipment for the EM sources and receivers mature or is new equipment coming out?

Near Surface Organizers:
Li Peiming
Gerard Schuster Locations: BICC Conference Room 308 The near-surface seismic problem is one of the greatest challenges in accurate imaging of land seismic data. For example, large velocity + density variations at the near surface introduce strong scattering, reverberations, and phase shifts in specular reflections so that deeper portions of the subsurface are poorly imaged. The goal of this workshop is to discuss the state of the art in characterizing the near surface and the methodologies for characterizing and correcting the near-surface effects in complex environments. We will invite recognized experts to lead the discussion and give keynote talks. The following topics will be covered: - Identify the most challenging problems for solving near-surface problems in complex areas.
- Define possible research directions and possible solutions to this problem.
- Methods and applications of near surface corrections for multi-component geophysical surveys.
- New 3D and 2D processing techniques, including waveform inversion and modeling, in near surface geophysics.
- Case studies in complex areas with typical static problems.
