Gas hydrates (GH) are well known to have an influential effect on the velocity and attenuation of gas hydrate-bearing sediments (GHBS). Based rock physics modeling, sediment has been extensively used characterize distribution hydrate. However, results obtained from different models show a significant variation. In this study, we firstly review compare existing modeling for attenuation. The assu...

The microstructure of a porous medium and the physical characteristics of the solid and fluid phases determine the macroscopic transport properties of the medium. The purpose of this paper is to test numerical calculations of the geometrical and transport properties (electrical conductivity, permeability, specific surface area, and surface conductivity) of porous, permeable rocks, given their 3...

Rock grain size parameter is the key of reservoir rock physics analysis. The study found that relationship between NMR T 2 spectrum and distribution curve directly related to id="M2"> rock, so you can use id="M3"> retrieve spectral data. Based on calculation core experiment results ...

All geophysical methods detect fractures indirectly [e.g. NAS/NRC, 1996]. Typically several levels of interpretation follow the collection of raw geophysical data. Field measurements must first be interpreted (for example from travel time to velocities or identification of the origin of seismic scattering features in the coda). Then the fracture properties must be deduced using models (from sei...

In this paper, a 3D Smooth Particle Hydrodynamics (SPH) simulator for modeling grain scale fluid flow in porous rock is presented. The versatility of the SPH method has driven its use in increasingly complex areas of flow analysis, including flows related to porous rock for both groundwater and petroleum reservoir research. Previous approaches to such problems using SPH have involved the use of...
