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
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.

Subsurface Structure from Ambient Seismic Noise

71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009, 2009
One of the applications of seismic interferometry (SI) by cross-correlation is the retrieval of the reflection response of the subsurface from ambient seismic noise recorded at the surface.

Extracting Stable Seismic Core Phases from Ambient Seismic Noise

Bulletin of the Seismological Society of America, 2015
Abstract Ambient seismic‐noise correlation is a powerful tool for extracting the seismic core phases that propagate through the interior of the Earth. In this study, we present and refine the root‐mean‐square‐stacking method to extract stable core phases (e.g., PcP , ScS , PcS / ScP , and PKiKP ) from within the Central Alborz region, Iran, using ...

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.
