Event-driven Seismic Interferometry with Ambient Seismic Noise

72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010
By cross-correlating recordings of ambient seismic noise, one can retrieve the subsurface reflection response. The quality of the retrieved reflections would depend on the qualities of the ambient noise. In a previous study, we cross-correlated ambient-noise data recorded in a desert area in North Africa and showed that we retrieved reflections.

Ambient seismic noise tomography at Ekofisk

Geophysics, 2015
ABSTRACT We have studied an approximately 40-hr recording from the Life of Field Seismic array installed over Ekofisk field to assess whether the recorded ambient seismic energy was suitable for passive seismic surface-wave interferometry. Passive seismic interferometry aims to retrieve virtual seismic sources by crosscorrelation.

Ambient seismic noise tomography at Valhall

SEG Technical Program Expanded Abstracts 2011, 2011
Although permanent ocean-bottom cables installed at the Valhall field record high-quality and repeatable active seismic surveys, even in absence of active seismic shooting the array can record an abundance of seismic energy. Seismic interferometry of 29 hours of passive seismic data generates omnidirectional Scholte-wave virtual-sources at very low ...

Wavefield reconstruction inversion for ambient seismic noise

2020
<p>With the advent of large and dense seismic arrays, there is an opportunity for novel inversion methods that exploit the information captured by stations in close proximity to each other. Estimating surface waves dispersion is an interest for many geophysical applications using both active and passive seismic data.
