Seismoelectric coupling in an electric isotropic and elastic anisotropic medium is developed using a primary–secondary formulation. The anisotropy is of vertical transverse isotropic type and concerns only the poroelastic parameters. Based on our finite difference time domain algorithm, we solve the seismoelectric response to an explosive...

In the field of exploration geophysics various methods are applied to determine the physical properties of the subsurface of the Earth. Some of the methods most widely used are seismic and electromagnetic surveys, which are each used according to the type of information that is being sought and their ability to provide that information. The...

Seismic and electromagnetic imaging methods both provide the geophysicist with different types of medium parameters. Seismic methods are sensitive to the elastic properties of the medium, while electromagnetic methods are sensitive to the electric properties. In porous-saturated media, these two wave fields occur as a coupled system, which is...

Schakel, M.D. (author)
Coupled seismic and electromagnetic wave propagation is studied theoretically and experimentally. This coupling arises because of the electrochemical double layer, which exists along the solid-grain/fluid-electrolyte boundaries of porous media. Within the double layer, charge is redistributed, creating an excess electrical charge in the fluid...

Coupled seismic and electromagnetic (EM) wave effects in fluid-saturated porous media are measured since decades. However, direct comparisons between theoretical seismoelectric wavefields and measurements are scarce. A seismoelectric full-waveform numerical model is developed, which predicts both the fluid pressure and the electric wavefields in...

Menzel-Jones, G. (author)
Elastodynamic and electromagnetic processes are coupled together in saturated, porous media, by a phenomenon known as the electrokinetic effect. In horizontally layered media, the seismoelectric system, which contains the coupled elastodynamic and electromagnetic systems, can be separated into two independent modes of propagation: SH-TE and P-SV...

A recent novel technique known as seismic interferometry makes use of seismic ‘noise’ to reconstruct a Green’s function between two receivers by crosscorrelation. This technique can be applied for example in permanent subsurface monitoring using passive seismics or the creation of virtual sources on positions where only recordings were made. The...

At interfaces between porous media acoustic energy can be converted into electromagnetic energy or vice versa by the electrokinetic effect. Operators exist describing this conversion, however these act on (one-way) upgoing and downgoing waves, while in nature only the total (two-way) wavefield exists. In this thesis mathematical formulations are...
