Abstract

Here we present a North Sea case history of 3D pre-stack depth migration, where the velocity-depth model has been built iteratively using a new pre-stack velocity updating scheme. In order to assess improvement in image quality throughout the model building process, we analyse post-stack depth migration results, their corresponding pre-stack images, and image gathers for each iteration.
