Abstract

Interpreting seismic data directly on depth-migrated volumes is an increasingly popular workflow as it allows for more realistically looking geological dips and geometries compared to two-way time domain approaches. While velocities used for depth imaging account for lateral velocity heterogeneity and anisotropy, they may not position seismic reflectors at their true depth, resulting in mismatches between depth-migrated horizons and the corresponding well markers. However, to identify prospects and compute volumes, it is essential to use seismic horizons that are properly calibrated in depth and match all available well data. Similarly, when performing seismic inversion or structural/property modeling, all subsurface elements (seismic attributes, faults, maps, grids, or geobodies) must be depth-consistent with this data.
