Abstract

The present study from the Vienna Basin (Austria) shows the result of different processing techniques in time including (i) pre-stack time migration, (ii) post-stack time migration and (iii) Common Reflection Surface (CRS) processing. Pre-stack time migration was the preferred approach to obtain a high-resolution image of the relatively shallow Neogene section (i.e., 0 ~2.5 km). Post-stack time migration using only the low-frequency components of the seismic signal yields improved images from the deeper Cretaceous and Triassic (pre-Neogene) section at ~2.5 – ~5.0 km depth. Finally, the best image of the complex geological structures in the deep pre-Neogene target area is obtained with CRS processing. Target-oriented data re-processing should be considered as an effective tool to increase the information content of an existing data set. Focusing on the principal attributes of a dataset using robust techniques (e.g., low-frequency processing, post-stack migration approach, etc.) or targeted techniques (e.g., CRS processing) have the potential to reveal information that is not obvious in conventionally processed data.
