Acoustical properties of double porosity granular materials [PDF]
The Journal of the Acoustical Society of America, 2011 Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating properties. An emerging field is the study of the acoustical properties of multiscale porous materials. An example of these is a granular material in which the particles are porous.

Fluid Discrimination in Ultra-Deep Reservoirs Based on a Double Double-Porosity Theory
Frontiers in Earth Science, 2021 We develop a methodology, based on rock-physics templates, to effectively identify reservoir fluids in ultra-deep reservoirs, where the poroelasticity model is based on the double double-porosity theory.

Theory of Filtration in a Double Porosity Medium
Doklady Earth Sciences, 2019 This paper defines a generalized mathematical model of filtration in a double porosity medium, taking into ac- count recent ideas on liquid and gas flow in rocks with an anomalously low permeability (including nanoporous rocks). The obtained generalized equation takes into consideration, in contrast to the classical model, the integral effects of ...

Journal of Ocean Engineering and Science, 2023 In the present article, we have used the three-phase-lag model of thermoelasticity to formulate a two dimensional problem of non homogeneous, isotropic, double porous media with a gravitational field impact. Thermal shock of constant intensity is applied

Acta Physica Sinica, 2014 A new algorithm for P-wave reverse time migration (RTM) in a fracture-induced TTI double-porosity medium is proposed in this paper, by combining RTM with the method of P-and S-wave field separation in high-order staggered grid finitedifference scheme.
