QERT - Quadrupole Electrical Resistivity Tomography

2020
<p><span>The quadrupole technique for geoelectrics yields the apparent resistivity in a tensorial form in contrast to the scalar apparent resistivity obtained from classical geoelectrics. The quadrupole method in geoelectrics has been applied in the past only for long offsets between transmitter and receiver.

DC Electrical Resistance Tomography Inversion

2021
Direct current electrical resistivity imaging is provided by measuring the vertical and horizontal electrical potential variations of subsurface structures using surface and borehole records. To recover the resistivity tomograms from the observed data, a non-linear inverse problem is required to be iteratively solved. A 2.5-dimensional forward modeling

Electrical resistivity tomography for petrophysical investigation

4th EEGS Meeting, 1998
Determination of physical parameters of rock samples is essential to characterize their composition and structure. One of these parameters is electrical resistivity. Depending on porosity, resistivity of the pore fluid, saturation degree and matrix properties (esp.

Non-Iterative Imaging Method for Electrical Resistance Tomography

2009
Electrical Resistance Tomography (ERT) is a body of methods and techniques aimed to reconstruct the spatial distribution of the resistivity of a material starting from the knowledge of boundary measurements such as, for instance, the Neumann-to-Dirichlet map.

An Electrical Resistive Tomography Based on Direct Information

2004
An approach to non destructive testing suitable for solving a class of particular inverse problems whose peculiarity is to have the defect electrically accessible is proposed. The impact of this feature on the mathematical formulation of the problem and the advantages in terms of improvement of the sensitivity of the measurement system are discussed ...
