Wave propagation in multiscale porous media
More LessWe consider a fractured porous medium, i.e. a dual-porosity medium which consists of two interacting porous systems whose permeabilities are very different.

Upscaling poroelastic media
Authors B. Gurevich and S. A. ShapiroUpscaling of heterogeneous porous reservoirs differs from the upscaling in elastic media due to the effect of the wave-induced fluid flow that may occur between areas of different compliance.

Simple hereditary media models with singular memory kernels for transient waves in lossy media
By V. E. RokThe macroscopic wave dispersion relations of an inhomogeneous porous media are strongly affected by scattering and absorption energy by grams, boundaries of micro-pores, and vissous boundary layer in the pore fluid flow.

Upscaling in reservoir engineering and geophysics
Authors L. Paterson and J. GunningThe word upscaling is loosely used to mean averaging fine-scale information to give the same effective properties at the coarse-scale. However, a precise definition is usually user and purpose specific, and more particularly dependent on the physical model used to define the notion of "effective ". This deserves some discussion.

Integrating effective flow and seismic properties
Authors G. E. Pickup and C. D. MacBethMany reservoirs (bath hydrocarbon-hearing and aquifers) are fractured, and mach work has been carried to characterize their proporties and to simulate tluid flow through them. Due to stress fields, fractures are frequentty aligned, giving rise to anisotropic proporties. In particular, for a reservoir with parallel fractures, fluid flow will be much stronger in one direction than in another. One method of detecting fracture orientation, is using seismic measurements. In this abstract, we show how seismic anisotropy depends on microscopic proporties, such as the elastic compliance within a fracture, and how seismic anisotropy can be used to predict permeability anisotropy.

Power-law behavior of well log spectra
Authors J. P. Stefani and G. S. DeThis talk contains two notable observations: 1) the spatial spectra of well logs follow a powerlaw behavior, and 2) the value of the power is only weakly dependent on log type and basin type.

Pore-scale modelling of multiphase flow in rocks
Authors L. Paterson, M. A. Knackstedt and W. V. PinczewskiThe seismic response of multiphase flow through reservoirs is a key component of quantitatively interpreting 4D seismic. It is known that the seismic response does not fust depend on the fractions of fluids present, but also on the way that the phases are distributed. Various patchy saturation distributions can arise degending on whether the fluid displacements are dominated by capillary, viscosity or gravity.
