Usage of common image gathers for shallow seismic source localization

Research output: Contribution to journalConference articlepeer-review

Abstract

In this study, a new approach to shallow seismic source localization is presented. Facing the shallow subsurface complexity combined with poor data quality and quantity, a migration based diffraction imaging methodology is presented. Utilizing common image gathers analysis, the diffractive nature of the source is characterized. An automatic correctness criterion suggested for the analysis of the migrated gathers allows for a joint localization and migration velocity analysis. Through detailed analysis of 2D synthetic and field examples the influence of velocity on localization errors is demonstrated. A methodology for 3D analysis is also presented for a synthetic case.
