Probabilistic seismic petrophysical inversion with statistical double-porosity Biot-Rayleigh model
Geophysics, 2023Petrophysical inversion quantitatively extracts reservoir properties from seismic data/attributes, which has gained increasing attention in assisting hydrocarbon reservoir exploration and evaluation.

Inhomogeneous waves propagation in double-porosity thermoelastic media
International Journal of Numerical Methods for Heat & Fluid Flow, 2023Purpose The purpose of this study is to investigate the reflection of plane waves in a double-porosity (DP) thermoelastic medium. Design/methodology/approach To derive the theoretical formulas for elastic wave propagation velocities through the ...

Solution of the problems of thermoelasticity for a circle with double porosity
Journal of thermal stresses, 2023The main purpose of this work presents some explicit solutions of boundary value problems in the theory of thermoelasticity for solids with double porosity. Special representations are constructed for the general solution of basic equations.

A variational approach to double‐porosity problems [PDF]
Asymptotic Analysis, 2004 The present paper outlines an approach by \(\Gamma\)-convergence to some problems related to ``double-porosity'' homogenization. In the framework of the authors, the homogenization process involves the analysis of energies defined on some (mutually disconnected) highly oscillating connected sets, in whose complement an energy density satisfying weaker ...

Rayleigh-type waves are investigated in a layered model composed of thermoelastic medium with double porosity structure. Using appropriate boundary conditions, the dispersion relation is obtained, which provides multi-modes, dispersive and attenuating ...

Singular Double Porosity Model
Applicable Analysis, 2003We consider the linear parabolic equation describing the transport of a contaminant in a porous media crossed by a net of infinitely thin fractures. The permeability is very high in the fractures but very low in the porous blocks. We derive the homogenized model corresponding to a net of infinitely thin fractures, by means of the singular measures ...

On Inflow to a Tunnel in a Fractured Double‐Porosity Aquifer
Ground Water, 2021Inflow to a tunnel is a great public concern and is closely related to groundwater hydrology, geotechnical engineering, and mining engineering, among other disciplines. Rapid computation of inflow to a tunnel provides a timely means for quickly assessing

3D PRINTED SOUND-ABSORBING MATERIALS WITH DOUBLE POROSITY
Inter-Noise 2022, 2023The paper shows that acoustic materials with double porosity can be 3D printed with the appropriate design of the main pore network and the contrasted micro-porous skeleton. The microporous structure is obtained through the use of appropriate additive manufacturing (AM) technology, raw material, and process parameters.

Double Porosity Biot Theory Extension
70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008Reservoir stones are generally a porous medium, heterogeneous, fractured and saturated with oil, gas or water. The analysis of wave propagation on these media is carried out using the Biot-Gassman theory for porous media and an extended Biot's theory for fractured porous medium.

Acoustic wave propagation in double porosity media
The Journal of the Acoustical Society of America, 2003A study of the propagation of waves in porous media with an interconnected network of pores and micropores of very different characteristic sizes, saturated by a compressible Newtonian fluid, is proposed. With this aim, the homogenization technique for periodic separated scales media, is applied to realistic double porosity materials with motionless ...
