... occurs due to chemical and mechanical compaction. The chemical and mechanical compaction may include a pressure solution and a reduction in permeability could be explained by this pressure solution [1]-[5]. Yasuhara, et al. [6] conducted flow-through experiments on a single fracture in granite under...

...-wave modes exist that propagate along fracture intersections. Ultrasonic waves propagated along the intersection between two orthogonal, synthetic fractures in aluminum were compared with waves that were propagated through the bulk and along single fractures as a function of stress. Intersections give...

... ABSTRACT: Laboratory experiments were performed to determine the spatial variability of seismic fracture specific stiffness and the dominant flow path within a single fracture subjected to normal stress. Two cylindrical granite specimens were used in the study: an intact sample and a fractured...

... ABSTRACT: A new 2D numerical simulation method for water flows in discrete fracture networks is proposed. Firstly, hydraulic analysis of a single fracture is carried out. Each fracture in a discrete fracture network is treated as a weighted branch with a start node and an end node...

... waste or storage repositories. While the effects of single fractures or sets of parallel fractures on seismic wave propagation have been studied by many scientists and engineers, little research has been performed to determine the role of fracture intersections on seismic wave attenuation and velocity...

... able to collapse the statistical fluctuations in these relationships by using zeroth order approach. 1. INTRODUCTION Understanding the mechanical and hydraulic properties of single fractures is important in many scientific and engineering fields, i.e, nuclear waste isolation, oil & gas...

... through a single fracture depends on the spatial distribution of the aperture including their connectivity, the contact area distribution of the fracture and fluid properties. The aperture and the contact area distributions of a fracture depend on the stress system acting on the joint. This research deals...

... correlations. They found that relative permeabilities are sensitive to the nature and range of spatial correlation of the apertures. Pyrak-Noltet al. (1990) examined unsaturated flow in single fractures for the case of a non-wetting phase invading a wetting phase fluid (such as mercury injected into a fracture...

... ABSTRACT: A numerical procedure is presented for the simultaneous inversion of hydraulic and electrical data describing the flow of fluid and electrical current through a single fracture. Application of the inversion procedure to hydraulic and electrical data computed for an arbitrary aperture...

... is the hydromechanical behavior of a single fracture. The mechanical and transport properties of fractures in rock depend on the topography of the contacting surfaces and the degree of mismatch between them. Understanding this behavior in the earth requires knowledge of how fracture topography and aperture scales...

... ABSTRACT ABSTRACT Current research on fracture hydrology at Lawrence Berkeley Laboratory is focused on two scales: the single fracture and fracture networks. In the area of single fractures, we have established a research program aimed at characterizing the geometry of the void spaces...

... ABSTRACT ABSTRACT: An analytical model that assumes variable height asperities and full interaction between them has been developed and implemented numerically to study the behavior of a single fracture under stress. The model has been used to calculate specific stiffness and aperture profiles...
