Fracture-Induced Permeability in Whitby Mudstone

Synthetic Rock Analogue for Permeability Studies of Rock Salt with Mudstone

Knowledge about the permeability of surrounding rock (salt rock and mudstone interlayer) is an important topic, which acts as a key parameter to characterize the tightness of gas storage. The goal of experiments that test the permeability of gas storage facilities in rock salt is to develop a synthetic analogue to use as a permeability model. To address the permeability of a mudstone/salt layer...

Ascorbic Acid Improves Vascular Permeability in Experimental-Induced Diabetic Rats

Background: The most devastating manifestations of diabetes mellitus are vascular complications. Although there are many factors involved in the pathogenesis of diabetic vasculopathy, many studies suggest a role for glucose–induced oxidative stress. Studies in animal models, have demonstrated that the administration of antioxidants restores normal endothelial functions. The study was designed t...

Electromotive Force in Electrochemical Modification of Mudstone

Permeability anisotropy induced by the shear displacement of rough fracture walls

The permeability anisotropy that results from a shear displacement ~u between the complementary self-affine walls of a rough fracture is investigated. Experiments in which a dyed fluid displaces a transparent one as it is radially injected into a transparent fracture exhibit a clear anisotropy in the presence of shear displacements, and allow us to estimate the ratio of the permeabilities for f...

Influence of fracture truncation on dispersion: A dual permeability model

Simulations with a dual permeability model show that a few discrete fractures can have a Ž . major influence on plume geometry. A limited number of truncated fractures 1–4 within a permeable matrix can create nearly circular plumes, with about the same degree of spreading in the direction transverse to the average hydraulic gradient as in the longitudinal direction. By comparison, continuous fr...
