Abstract

Oz Yilmaz, GeoTomo, Houston, describes a time-with-depth workflow for earth modelling and imaging in areas with irregular topography, complex near-surface, and complex subsurface based on analysis of seismic data in shot-receiver coordinates, not in midpoint-offset coordinates. Seismic data acquired in areas with irregular topography, complex near-surface, and complex subsurface require a customized analysis workflow. A near-surface is usually defined as a relatively unconsolidated, low-velocity soil column with less than 30 m thickness. Nevertheless, there are many areas where the near-surface thickness and velocities may vary significantly along the seismic line traverses. Additionally, a near-surface zone may include high-velocity outcrops and layers with vertically varying velocities.
