Using the similarity of diffraction imaging and passive seismic imaging, we propose a method that uses path-integral formulation to apply diffraction-type migration on time-shifted microseismic records and to focus seismic energy focuses at correct onsets and accurate locations in time coordinates. An efficient workflow is applied to do path-integral migration based on analytical integration. Passive seismic sources can be additionally highlighted by envelope stacking. Numerical experiments with synthetic data verify the effectiveness of the proposed method.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>An old paper is added to the collection of reproducible documents: Microseismic source localization using time-domain path-integral migration Localization of passive seismic sources is crucial for real-time monitoring of hydraulic fracturing.
