Electrical resistivity tomography for petrophysical investigation
4th EEGS Meeting, 1998Determination 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.

DC Electrical Resistance Tomography Inversion
2021Direct 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

An Electrical Resistive Tomography Based on Direct Information
2004An 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 ...

Cross-hole electrical resistivity tomography under extreme electrical resistivity conditions
2011Electrical Resistivity Tomography is a technique widely used for the investigation of the structure and fluid-dynamics of the shallow subsurface, particularly for hydro-geophysical purposes and using cross-borehole configurations . The results of ERT inversion and their usefulness in tackling and solving hydrogeophysical problems, even though ...
