This paper describes the applications of the fractured continuum model to the different enhanced geothermal systems reservoir conditions. The capability of the fractured continuum model to generate fracture characteristics expected in enhanced geothermal systems reservoir environments are demonstrated for single and multiple sets of fractures. Fracture characteristics are defined by fracture st...

      Many large oil and gas fields in the most productive world regions happen to be fractured. The exploration and development of these reservoirs is a true challenge for many operators. These difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. To successfully address these challenges, it is paramount to im...

Most of the Earth's crust contains fluids, and fractures are common throughout the upper part. They exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. In this paper, the stress-dependent permeability in fractured rock masses have been investigated considering the effects of nonlinear normal deformation and shear dilation o...

Discrete fracture network (DFN) is an effective means of describing the coupling heat flow in underground fractured rock mass. In this paper, improved DFN proposed by introducing correlation function trace length and aperture, which more consistent with real data. Next, based on model, influence roughness fluid transmission was evaluated, relationship between aperture joint coefficient (JRC) es...

Injection of cold fluids through/into deep formations may cause significant cooling, thermal stress, and possible fracturing. In this study, the fracturing low-permeability under one-dimensional heat conduction was investigated using a plane strain model. Dimensionless governing equations, with dimensionless fracture length , aperture spacing time effective confining stress were derived. Soluti...

The supracondylar process is usually a beak-like osseous prominence located at the anteromedial aspect of the distal portion of the humerus. It is usually asymptomatic but occasionally may compress underlying structures such as the median or ulnar nerve, the brachial artery or its branches. The term septal aperture defines an oval or round shaped bony defect of the septum that separates the ole...

Rainwater streaking down a vertical wall exhibited the characteristics of “fingered flow.” The wall serves as an analogy to film flow in a relatively smooth and wide aperture fracture. A digital photograph of the wall suggests that the vertical distribution of water is heavy-tailed. A fractional-order advection-dispersion equation is used as a model.
