Applications of seismic interferometry to seismic field data

The Journal of the Acoustical Society of America, 2007
In seismic interferometry one extracts the Green’s function of a system from fluctuations in the system. This makes it possible to retrieve the waves that propagate between receivers, as if one of the receivers acts as a source. Examples are presented of this principle to field data.

Effect of Intrinsic Losses on Seismic Interferometry

70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008
Seismic interferometry (SI) is the process of generating new seismic traces from the cross-correlation of existing traces. One of the starting assumptions for deriving the SI representation equations is that of a lossless medium. In practice, this condition is not always met.

Seismic Interferometry

2009
Seismic interferometry is an exciting field in geophysics utilising multiple scattering events to provide unprecedented views of the Earth's subsurface. This is a comprehensive book describing the theory and practice of seismic interferometry with an emphasis on applications in exploration seismology.

Seismic Interferometry in Near-Surface Seismics - An Experiment

Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics, 2006
Seismic interferometry (SI) is the process of generating new seismic records from the cross-correlation of existing records. The interest to SI is growing, but mainly in hydrocarbon exploration and global seismology. The application of SI to shallow seismics could help to extract more information form the data and at the same time save efforts and time

Seismic Interferometry Applied to Seismic Background-Noise Field Data

Proceedings of the 8th SEGJ International Symposium, 2006
One of the applications of Seismic Interferometry (SI) is the reconstruction of the Earth’s reflection response from the crosscorrelation of seismic background noise recorded at the surface. In recent years, several authors have derived the relations that govern this process.

Cross-Hole Tomography Using Seismic Interferometry

68th EAGE Conference and Exhibition incorporating SPE EUROPEC 2006, 2006
The Virtual Source (VS) is a kind of Seismic Interferometry and synthesizes a new seismic record whose source comes from a receiver location by processing cross-correlation to plural records. We make experiments in the laboratory and simulations in order to synthesize a VS data from records between cross-holes, and confirm this data can be used for ...

Studying seismic events via satellite interferometry

Eighth International Conference on Remote Sensing and Geoinformation of the Environment (RSCy2020), 2020
Satellite radar instruments deliver SAR data that are able to provide information on the magnitude of ground motions in range of centimeters. Such information is of extreme importance is assessing the consequences of natural or man-made disasters. Since earthquakes are occurring constantly and are not possible to predict it is recognized that any ...

Efficient Computation of Passive Seismic Interferometry

69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007
P214 Efficient Computation of Passive Seismic Interferometry J.W. Thorbecke* (Delft University of Technology) & G.G. Drijkoningen (Delft University of Technology) SUMMARY Seismic interferometry is from a computationally point of view based on cross-correlating two signals. One application of seismic interferometry lies in passive seismics.

Seismic interferometry by tangent‐phase correction

Geophysical Prospecting, 2014
ABSTRACTWe present a modified interferometry method based on local tangent‐phase analysis, which corrects the cross‐correlated data before summation. The approach makes it possible to synthesize virtual signals usually vanishing in the conventional seismic interferometry summation.

Seismic Interferometry with Underground Moving Source

68th EAGE Conference and Exhibition incorporating SPE EUROPEC 2006, 2006
SUMMARY The reflection response can be obtained by the cross-correlation of the transmission responses, which is called "seismic interferometry". We apply this technique to the field data observed by using several different seismic sources. In this paper, we introduce a result of the field examination done toward practical use of the seismic ...
