Seismic interferometry vs. static corrections in seismic data processing
Arabian Journal of Geosciences, 2021The attenuation of distortion caused by the shallow layer generates reliable subsoil’s pictures, which static corrections attempt to do, under the assumption of surface consistency. However, such an assumption is frequently invalid, and nowadays, this problem is still unsolved.

Body-wave Receiver-pair Seismic Interferometry
Proceedings, 2013With seismic interferometry reflections can be retrieved between station positions. In the classical form, the reflections are retrieved by a crosscorrelation of observations and an integration over subsurface sources. For a specific dataset, however, the actual source distribution might not be sufficient to approximate the source integral.

Seismic interferometry—turning noise into signal
The Leading Edge, 2006Turning noise into useful data—every geophysicist's dream? And now it seems possible. The field of seismic interferometry has at its foundation a shift in the way we think about the parts of the signal that are currently filtered out of most analyses—complicated seismic codas (the multiply scattered parts of seismic waveforms) and background noise ...

Event-driven Seismic Interferometry with Ambient Seismic Noise
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010By 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.

Near-surface site investigation by seismic interferometry using urban traffic noise in Singapore
Geophysics, 2019We have evaluated a field test in the city of Singapore to assess the feasibility of the passive seismic survey for bedrock depth determination and to further investigate the optimal acquisition parameters.

Seismic interferometry is a powerful tool to monitor the seismic velocity change associated with volcanic eruptions. For the monitoring, changes in seismic velocity with environmental origins (such as precipitation) are problematic. In order to model the

Groundwater Level Monitoring Tests with Seismic Interferometry
NSG2020 26th European Meeting of Environmental and Engineering Geophysics, 2020Summary The objective of this work is to evaluate whether the seismic passive interferometry technique can be used to monitor undeground water variations in both unconfined and confined aquifers that present different hydrogeological characteristics. We collected ambient vibrations in two different water catchment fields where the water level has been ...

Bedrock detection based on seismic interferometry using ambient noise in Singapore
SEG technical program expanded abstracts, 2020SUMMARY The city-state of Singapore principally sits on granite bedrock known as the Bukit Timah formation. The Bukit Timah gran-ite outcrops in the centre of Singapore, but it is buried below quaternary sediments known as the Old Alluvium formation in ...

Source‐receiver seismic interferometry
SEG Technical Program Expanded Abstracts 2009, 2009Seismic (or more generally, wavefield) interferometry allows receivers to assume the role of sources, or vice versa. Recorded waveforms (theoretically, Green’s functions) can be constructed from new ‘virtual’ source positions at which only receivers have been physically located.
