Journal ArticleDOI
Review: Some low-frequency electrical methods for subsurface characterization and monitoring in hydrogeology
TL;DR: In this paper, the authors used self-potential, resistivity, and induced polarization techniques to measure the electrical response associated with the in-situ generation of electrical current due to the flow of pore water in porous media, a salinity gradient, and the concentration of redox-active species.
Journal ArticleDOI
Complex conductivity of soils
André Revil,A. Coperey,Zhenlu Shao,Zhenlu Shao,Nicolas Florsch,Ida Lykke Fabricius,Y. Deng,Y. Deng,Joost Delsman,P.S. Pauw,Marios Karaoulis,P.G.B. de Louw,E.S. van Baaren,Willem Dabekaussen,Armin Menkovic,J.L. Gunnink +15 more
TL;DR: In this paper, the authors investigated the complex conductivity of 71 soils samples (including four peat samples) and one clean sand in the frequency range 0.1 Hz to 45 kHz in order to test the predictions of the dynamic Stern polarization model of porous media in terms of relationship between the quadrature conductivity and the surface conductivity.
Journal ArticleDOI
Image-guided inversion of electrical resistivity data
TL;DR: In this article, the structure features are quantified and represented by a tensor field calculated from the image and the structural information is added to the inversion during the construction of the inverse of model covariance.
Journal ArticleDOI
4D active time constrained resistivity inversion
TL;DR: The new algorithm, named 4D Active Time Constrained (4D-ATC), is shown to be a useful tool for processing time-lapse resistivity data, which can be used with minor modifications to other types of time- lapse geophysical data.
Journal ArticleDOI
Time-lapse three-dimensional inversion of complex conductivity data using an active time constrained (ATC) approach
Marios Karaoulis,André Revil,André Revil,D. Dale Werkema,Burke J. Minsley,W. F. Woodruff,Andreas Kemna +6 more
TL;DR: In this article, a new time-lapse 3D modeling and inversional algorithm is proposed to simulate the evolution of complex resistivity over time using hexahedron cells.
