Through the support of the SEG Research Committee Description: Substantial oil and gas potential and proven reserves onshore guarantee that land seismic will be a major factor in securing the supply of vital energy to the world. High-fold and high-productivity seismic acquisition offshore and in land areas of mild topography have benefited seismic imaging and interpretation greatly over the past two decades. The innovation path, however, has generally been much slower for seismic acquisition, processing, and imaging in foothills and thrust-belt settings with rugged topography. This is caused mainly by difficult (i.e., expensive) access in mountainous terrains and the poorly constrained heterogeneity of the near- and mid- subsurface. Land seismic -- 2D and 3D, single-component and multi-component, acoustic and elastic -- in thrust-belts settings and other structurally complex environments raise unique challenges that require new thinking and novel technological approaches. Emphasis in this workshop is on integrated case studies -- whether successful or disappointing -- including those that incorporate non-seismic methods. Topics that will be addressed in invited presentations and extensive discussion periods include: - Acquisition equipment and design
- Near and mid-surface challenges (energy penetration, shot-generated noise, body- and surface-wave reverberations, mode conversions and scattering, near-surface velocity model building)
- Conventional static versus dynamics correction for near-surface distortions; imaging from topography
- Signal-to-noise enhancement
- Velocity model building and depth imaging
