“…Using the reciprocity theorem of the correlation type, they generalized Claerbout's relation between transmission and reflection responses to 3D inhomogeneous acoustic and elastic media. This theory was confirmed with numerically modeled seismic data in laterally varying media [58]. Wapenaar et al [47] have shown that using crosscorrelation to retrieve the Green's function response between two stations is in principle not limited to seismic systems but holds for a wide class of phenomena, including seismoelectromagnetic wave propagation.…”

We experimentally validate a relatively recent electrokinetic formulation of the streaming potential (SP) coefficient as developed by Pride (1994). The start of our investigation focuses on the streaming potential coefficient, which gives rise to the coupling of mechanical and electromagnetic fields. It is found that the theoretical amplitude values of this dynamic SP coefficient are in good agreement with the normalized experimental results over a wide frequency range, assuming no frequency dependence of the bulk conductivity. By adopting the full set of electrokinetic equations, a full-waveform wave propagation model is formulated. We compare the model predictions, neglecting the interface response and modeling only the coseismic fields, with laboratory measurements of a seismic wave of frequency 500 kHz that generates electromagnetic signals. Agreement is observed between measurement and electrokinetic theory regarding the coseismic electric field. The governing equations are subsequently adopted to study the applicability of seismoelectric interferometry. It is shown that seismic sources at a single boundary location are sufficient to retrieve the 1D seismoelectric responses, both for the coseismic and interface components, in a layered model.

“…On the other hand, the seismic wave undergoes only weak losses, amplitude errors will therefore be weak. The spurious event that resides in one half of the retrieved symmetrized Green's function is non‐stationary with respect to the location of the boundary of the domain of reciprocity, therefore the occurrence of randomly distributed noise sources on the boundary might result in destructive interference of the spurious event, similar to Draganov et al (2003, 2006).…”

S U M M A R YInterferometric Green's function representations can be used to retrieve a Green's function between two receiver stations, effectively turning one receiver into a source. Through reciprocity theorems of the convolution and correlation types, we derive interferometric Green's function representations for coupled electromagnetic and seismic wave propagation in 1-D. These representations express a symmetrized Green's function in terms of correlations of sources distributed throughout the domain of reciprocity and on its boundary. The main challenge for practical implementation is the necessity of sources throughout a domain. Numerical examples show how this constraint can be relaxed for different configurations. In a configuration of two layers bounded by a vacuum, seismic noise sources behind the interface can be used to recover seismoelectric reflection responses that suffer from small amplitude losses, but are not corrupted by spurious events.

“…introdujo el concepto de "elaboración de imágenes mediante interferometría" (Interferometric Imaging) en referencia al proceso de obtención de imágenes sísmicas del subsuelo mediante correlaciones cruzadas. Luego,Wapenaar et al (2002) yWapenaar (2003) formalmente generalizan el teorema de Claerbout, extendiéndolo a medios acústicos y elásticos inhomogéneos en 3D, siendo posteriormente confirmado mediante aplicaciones numéricas y datos de sísmica pasiva(Draganov et al, 2003(Draganov et al, , 2007b.En la década de los´90, Fink ha explotado la propiedad de la invarianza de la ecuación de movimiento a la reversión temporal. El mismo ha demostrado que, en medios sin pérdidas anelásticas, la reversión temporal permite focalizar, en su punto de partida, la energía dispersada en el subsuelo heterogéneo(Fink et al, 2000).…”
