In its natural state, loess can be considered as an unstable soil, which develops large
deformations when moistened. In Argentina, loess is used in most Geotechnical …

The effect of sub‐core scale heterogeneity on fluid distribution pattern, and the electrical and
acoustic properties of a typical reservoir rock was studied by performing drainage and …

So-called Archie rocks are characterized by a resistivity index (RI) versus water saturation
that plots as a straight line on log-log scale, the line's slope being equal to-n where n is the …

The electrical conductivity of brine‐saturated rock is predominantly dependent on the
geometry and topology of the pore space. When a resistive second phase (eg, air in the …

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 …

Gas diffusion modeling in percolation clusters provides a theoretical framework to address
gas transport in porous materials and soils. Applying this methodology, above the …

Various methods have been proposed for the evaluation of reservoir rock wettability. Among
them, Amott–Harvey and USBM are the most commonly used approaches in industry. Some …

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 …

Laboratory core flooding experiment was run to investigate the joint use of electrical
resistivity, ultrasonic velocities and 3D images of fluid distribution to improve current …
