- Comparison of methods for extracting ADCIGs from RTM (2014, methodology): “For 3D data, the LSIC computation will be very expensive because they require 5D FTs to ODCIGs and a correponding mapping between reflection angles and wavenumbers (Fomel, 2004; Xu et al., 2011).”
- Automatic velocity analysis via shot profile migration (2008, methodology): “Jθ = 1 2 ‖PθI‖2 = 1 2 ∥∥∥∥ ∂∂θRI ∥∥∥∥2 (2) where R is the Radon transform (Sava and Fomel, 2003) from offset to angle θ, R−1 its inverse.”
- Angle‐domain common‐image gathers for migration velocity analysis by wavefield‐continuation imaging (2004, methodology): “The application of the insights provided by our analysis may substantially improve the results of the following three procedures: (1) measurement of velocity errors from ADCIGs by residual moveout (RMO) analysis, (2) inversion of RMO measurements into velocity updates, and (3) computation of ADCIGs…”
- Reverse-Time Migration using the Poynting Vector (2006, methodology): “In wave-equation shot-profile migration including RTM, we can obtain angle domain common image gathers (ADCIGs) after migration by transforming offset domain common image gathers (ODCIGs) which are computed during migration (Rickett and Sava, 2002; Sava and Fomel, 2003).”
- Isotropic angle-domain elastic reverse-time migration (2008, background): “This leads to representations of reflectivity as a function of angles of incidence and reflection at all points in the imaged volume (Sava and Fomel, 2003).”
- Amplitude and kinematic corrections of migrated images for nonunitary imaging operators (2004, background): “The angle panels are directly created after migration from the offset panels (Stolt and Weglein, 1985; Weglein and Stolt, 1999; Sava et al., 2001; Sava and Fomel, 2003).”
