Abstract

In areas with severe topographic relief, complex near-surface structure, and thick weathered/sub-weathered zones, first break refraction static corrections often do not work properly to meet the needs of data processing. It is necessary to carry out a study of tomographic static corrections in these areas. Conventional tomographic static corrections, however, are mostly used for long wavelength static corrections and therefore do not fully improve the resolution of tomographic models. In this paper, we introduce a novel technique to implement tomographic static corrections by incorporating irregular grid tomography and fat-ray tomography with an attendant quality control method. Theoretical tests and practical data applications presented in this paper suggest that these new approaches solve the issues of static corrections successfully.
