Our new method incorporates fluid pressure communication into inclusion-based models of elastic wave velocities in porous rocks by defining effective elastic moduli for fluid-filled inclusions. We illustrate this approach with two models: (1) flow between nearest-neighbor pairs of inclusions and (2) flow through a network of inclusions that communicates fluid pressure throughout a rock sample. ...

Transient phase change through a horizontal channel that subjected to discrete heat flux and filled with porous media of high-conductivity material, copper, is numerically investigated with n-pentane as the working fluid. The thermal non-equilibrium model is used in conjugate with the multiphase mixture model to analyze the transient behavior of fluid and solid phases. Three cases are studied r...

This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging—the MRF* Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principles...

Monitoring the rock-physics properties of subsurface is great importance for reservoir management. For either oil and gas applications or CO2 storage, seismic data are a valuable source information tracking changes in elastic which can be related to fluids saturation pressure within reservoir. Changes estimated with time-lapse full-waveform inversion. properties, such as saturation, inversion u...

Imbibition, the displacement of a nonwetting fluid by wetting fluid, plays central role in diverse energy, environmental, and industrial processes. While this process is typically studied homogeneous porous media with uniform permeabilities, many cases, have multiple parallel strata different permeabilities. How such stratification impacts dynamics imbibition, as well saturation after breaks th...
