Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Decision trees to characterise the roles of permeability and solubility on the prediction of oral absorption. [PDF]

, 2015
Oral absorption depends on many physiological, physiochemical and formulation factors. Two important properties that govern oral absorption are in vitro permeability and solubility, which are commonly used as indicators of human intestinal absorption ...

Permeability and dynamic elastic moduli of controlled porosity ultra-precision aerostatic structures [PDF]

, 2014
Porous ceramic aerostatic bearings enable precise and smooth motion and improved stiffness compared with widely used orifice restrictor bearings. However, the processing techniques so far used are too complex or rely in lowering the sintering temperature

Sensitivity analysis of permeability parameters of bovine nucleus pulposus obtained through inverse fitting of the nonlinear biphasic equation : effect of sampling strategy [PDF]

, 2012
Permeability controls the fluid flow into and out of soft tissue, and plays an important role in maintaining the health status of such tissue. Accurate determination of the parameters that define permeability is important for the interpretation of models

Static and dynamic connectivity in bed-scale models of faulted and unfaulted turbidites [PDF]

, 2007
A range of unfaulted and faulted bed-scale models with sheet-like bed geometries have been built and analysed in terms of static bed connectivity and fractional permeability assuming permeable sands and impermeable shales. The models are built using a

Evaluation of Core Samples from Low-Porosity and Low-Permeability Carbonate Reservoir with NMR Experiments

Chinese Journal of Magnetic Resonance, 2020
Well logging evaluation of the low-porosity and low-permeability carbonate reservoir is difficult because of its complex mineral composition, difficult to determine rock skeleton parameters, diverse types of reservoir space, complex pore structure and ...
