Time-lapse three-dimensional inversion of complex conductivity data using an active time constrained (ATC) approach (2011, background): “Recently, Revil et al. (Leroy et al. 2008; Leroy & Revil 2009; Revil & Florsch 2010; Schmutz et al. 2010) have also provided a complete theoretical framework explaining induced polarization measurements in terms of polarization of the electrical double layer coating on the surface of the grains.”
Determination of permeability from spectral induced polarization in granular media (2010, methodology): “(68) Because f can be computed from a double layer model (see Leroy et al. 2008 and Leroy & Revil 2009), the model has two unknowns only, F and σ 0S , that can be determined from the low and high asymptotic values of the electrical conductivity.”
An overview of the spectral induced polarization method for near-surface applications (2012, unknown): “For instance, Leroy et al. (2008) and Leroy and Revil (2009) recently modelled, based on the earlier works of de Lima and Sharma (1992) and Lesmes and Morgan (2001), the polarization mechanisms taking place in glass beads and in clay materials by coupling a Stern layer polarization model with an…”
Spectral induced polarization of shaly sands: Influence of the electrical double layer (2012, methodology): “[8] In clay minerals, the fraction of counterions in the Stern layer is very high (between 80% and 98% [Leroy and Revil, 2009, and references therein]).”
Geophysical Properties of the Near Surface Earth: Electrical Properties (2015, methodology): “…have concentrated on characterizing the electrical behavior of geomaterials as macroscopic multicomponent systems over a wide frequency range by combining different influencing polarization mechanisms (e.g., de Lima and Sharma, 1992; Glover et al., 2006b; Leroy and Revil, 2009; Leroy et al., 2008).”
Spectral induced polarization of partially saturated clay-rocks: a mechanistic approach (2010, methodology): “The complex conductivity of the Stern layer σ ∗S (in Sm −1) is determined as (Leroy & Revil 2009). σ ∗S = σ̄S + iωεs, (11) εs = 4.5ε0, (12) where εs represents the dielectric permittivity of the clay minerals (ε0 = 8.85 × 10−12 Fm−1, the dielectric permittivity of vacuum).”
