The Relationships Between Pre-Stack Migration Resolution and 3D Spatial Sampling with the High Density 3D Method

A12 THE RELATIONSHIPS BETWEEN PRE-STACK MIGRATION RESOLUTION AND 3D SPATIAL SAMPLING WITH THE HIGH DENSITY 3D METHOD Introduction 1 High Density 3D (HD3D) acquisition pursues a straightforward strategy: The use of dense trace acquisition and tight 3D spatial sampling to provide an optimal platform for subsequent processing operations. In recent years several HD3D surveys both land and marine have provided substantial improvements over the existing data. The following discussion attempts to isolate the significance of certain key elements in the HD3D story notably the issue of resolution after migration. We acknowledge that several issues contribute to improved temporal and spatial
