Technical Paper: Model Dip-Guided Imaging Condition for Reverse-Time Migration in VSP Scenario

Society: EAGE
Paper Number: A031
Presentation Date: 2012


We propose a new imaging condition aimed at eliminating swing artifacts, and also balancing the amplitude of the migrated features in RTM images with particular application to VSP data. It uses both the Umov-Poynting vector-based obliquity filter and a model-guided dip filter with several control parameters having a clear physical sense and permits the suppression of imaging artifacts. The quality and improvement of VSP images are demonstrated with two realistic synthetic data examples.
