Review of 3D Anisotropic Seismic Imaging Technology

Abstract

Recently, 3D seismic imaging techniques have been highlighted with increasing international demands on the discovery of new oil fields as well as the site characterization and CO 2 monitoring in carbon capture and storage. Because 3D seismic data can be distorted by various types of seismic anisotropy, a 3D anisotropic seismic imaging technique is required. In this study, we explain the geological reasons for seismic anisotropy and the influence of seismic anisotropy on 3D seismic data. Then, we introduce international research trends in anisotropic seismic imaging depending on seismic modeling, full-waveform inversion, and reverse-time migration. Finally, we introduce the current status and future trends in Korean 3D anisotropic seismic imaging technology.
