A fractal model for the electrical conductivity of water-saturated porous media during mineral precipitation-dissolution processes
(Elsevier, 2020-11)
Precipitation and dissolution are prime processes in carbonate rocks and being able to monitor them is of major importance for aquifer and reservoir exploitation or environmental studies. Electrical conductivity is a ...
An energy-based approach to estimate seismic attenuation due to wave-induced fluid flow in heterogeneous poroelastic media
(Wiley Blackwell Publishing, Inc, 2016-11)
Wave-induced fluid flow (WIFF) due to the presence of mesoscopic heterogeneities is considered as one of the main seismic attenuation mechanisms in the shallower parts of the Earth's crust. For this reason, several models ...
Modeling Forced Imbibition Processes and the Associated Seismic Attenuation in Heterogeneous Porous Rocks
(Blackwell Publishing, 2017-11)
Quantifying seismic attenuation during laboratory imbibition experiments can provide useful information toward the use of seismic waves for monitoring injection and extraction of fluids in the Earth's crust. However, a ...
Finite-element harmonic experiments to model fractured induced anisotropy in poroelastic media
(Elsevier, 2015-01)
Fractures in a fluid-saturated poroelastic-Biot-medium can be modeled as very thin highly permeable and compliant layers within a porous background. A Biot medium containing a dense set of aligned fractures behaves as an ...
Seismic Attenuation and Stiffness Modulus Dispersion in Porous Rocks Containing Stochastic Fracture Networks
(Wiley, 2018-01)
Understanding seismic attenuation and modulus dispersion mechanisms in fractured rocks can result in significant advances for the indirect characterization of such environments. In this paper, we study attenuation and ...
Saturation hysteresis effects on the seismic signatures ofpartially saturated heterogeneous porous rocks
(Blackwell Publishing Ltd, 2019-09-13)
Experimental evidence indicates that the spatial distribution of immiscible pore fluids in partially saturated media depends on the flow history and, thus, exhibits hysteresis effects. To date, most works concerned with ...
