Reflection or opening angle can be directly calculated from source and receiver wave propagation directions or source propagation direction and dip of the reflector. We studied a cost effective approach to generate 3D Reverse Time Migration (RTM) angle gathers from source wave propagation direction and dip information. This is a mapping process of the shot image onto an angle and azimuth plane using the most energetic arrivals and their amplitudes and propagation directions.Permalink: https://doi.org/10.1190/1.3627847FiguresReferencesRelatedDetailsCited byA non-reflecting wave equation through directional wave-field suppression and its finite difference implementation10 January 2022 | Scientific Reports, Vol. 12, No. 1Determination of the phase-velocity directions in anisotropic media using a direction vectorKai Yang and Jianfeng Zhang16 September 2022 | GEOPHYSICS, Vol. 87, No. 6Deprimary reverse time migration angle gathers with a stabilized Poynting vectorKai Yang, Xingpeng Dong, Xiaoyi Wang, and Jianfeng Zhang1 July 2022 | GEOPHYSICS, Vol. 87, No. 5Elastic reverse time migration angle gathers using a stabilized Poynting vector without zero points within the wave propagation rangesKai Yang, Xiaoyi Wang, and Jianfeng Zhang18 April 2022 | GEOPHYSICS, Vol. 87, No. 3First-order particle velocity equations of decoupled P- and S-wavefields and their application in elastic reverse time migrationZhiyuan Li, Youshan Liu, Guanghe Liang, Guoqiang Xue, and Runjie Wang12 October 2021 | GEOPHYSICS, Vol. 86, No. 6Suppressing residual low-frequency noise in VSP reverse time migration by combining wavefield decomposition imaging condition with Poynting vector filtering6 October 2020 | Exploration Geophysics, Vol. 52, No. 2Least-squares inversion-based elastic reverse time migration with PP- and PS-angle-domain common-imaging gathersBingluo Gu, Jianping Huang, Jianguang Han, Zhiming Ren, and Zhenchun Li5 January 2021 | GEOPHYSICS, Vol. 86, No. 1Well calibrated angle-gather tomography for anisotropic model buildingPo Zhang, Daoliu Wang, Sheng Xu, Jinjun Liu, and Hongbo Zhou30 September 2020Wavefield decomposition in arbitrary direction and an imaging condition based on stratigraphic dipXuebao Guo, Ying Shi, Weihong Wang, Hongliang Jing, and Zhen Zhang17 August 2020 | GEOPHYSICS, Vol. 85, No. 5Angle- and azimuth-domain common-image gathers by reverse time migration for 3D elastic isotropic mediaZabihollah Khaksar and George A.
