Journal of Seismic Exploration, 25: 339-358. Near surface topography is a main challenge in land seismic data processing. In conventional land data processing, seismic data are corrected to a reference datum before migration. We have developed a 2D topography pre-stack time migration (TPSTM) scheme that can handle surface topography with high near-surface velocities in land seismic imaging. The proposed TPSTM can be applied to 2D seismic data recorded on irregular surface without conventional static corrections. We describe the wave propagation through inhomogeneous media by defining two effective velocity parameters with the introduction of a floating datum. As a consequence, wave propagation phenomena in the complex near surface, such as near vertical incidences through a weathering layer and ray paths bending away from vertical in the presence of high near surface velocities, are correctly considered. The two effective velocity parameters can be estimated by velocity analysis and velocity scan so as to flatten events in the imaging gathers. The TPSTM to some extent correctly solves field static correction without applying conventional static correction based on the vertical incidence hypothesis. Applying TPSTM iteratively can also help to update the two velocities defined here and understand the variation of near surface macro velocity. In addition, we integrate residual static corrections into TPSTM to further address the residual static issue. The coherency along the events has been improved for stacking. Two-dimensional field datasets are used to demonstrate the proposed 2D TPSTM and workflow. High-quality imaging results are obtained.
