Abstract

Large lateral velocity gradient in the overburden causes structural imaging by conventionally applied time migration to fail. Depth migration can image such structures correctly but depends on a modelling procedure which is more costly than time methods and which brings interpretation into the processing sequence at a relatively early stage. In this presentation, an extension to prestack time migration is used to image the well known Marmousi synthetic to gauge the effectiveness of the extended technique relative to prestack depth migration results.
