The electrical conductivity of clay-free sandstones is customarily assumed to have negligible
surface conductivity contribution. The Fontainebleau sandstone, a clean sandstone with …

The relations among the resistivity, elastic-wave velocity, porosity, and permeability in
Fontainebleau sandstone samples from the Ile de France region, around Paris, France were …

Due to the intricate structure of carbonate rocks, relationships between porosity or saturation
and petrophysical transport properties classically used for reservoir estimation and recovery …

Permeability of intact and fractured core samples collected in EPS1 borehole at the Soultz-
sous-Forêts geothermal site (France) is used for neural network permeability prediction …

Standard reservoir evaluations are based on Archie's law relating the average water
saturation to the average electrical resistivity by R ind= S w-2. However, especially in the …

A model commonly applied to the estimation of water relative permeability krw in porous
media is the Burdine‐Brooks‐Corey model, which relies on a simplified picture of pores as a …

We address the problem of predicting saturation-dependent electrical conductivity σ σ in
packings of particles during drainage and imbibition. The effective-medium approximation …

Experimental results have shown that resistivity index can deviate from Archie's law at low
conductive phase saturation. Previous works have claimed that wettability and flow history …

Wettability has a profound effect on reservoir recovery and productivity. It determines the
microscopic distribution of fluids in the pore-space which, in turn, determine important global …

The numerical simulation of petrophysical properties in complex carbonate rocks is a
challenging task due to the unpredictable influence of the microporosity. This is particularly …
