Abstract

Summary

This paper investigates the seismic diffraction response of fluid escape features and their impact in diffraction imaging. Since fluid escape features are generally vertically aligned scattering objects, diffraction imaging has an illumination uplift compared to regular reflection depth migration. We compare diffraction modeling and imaging on concept models of fluid escape pipes with results to those of a South China Sea data set. The polarity reversal and tuning properties of diffraction imaging turn out to have important implications for detectability and resolution of fluid escape pipes and the interpretation of fluid migration and trap charging.
