A major issue to overcome when characterizing a deep fractured reservoir is that of data limitation due to accessibility and affordability. Moreover, the ability to map discontinuities in the rock with available geological and geophysical tools tends to decrease particularly as the scale of the discontinuity goes down. Geological characterization data include, but not limited to, measurements o...

[1] This paper investigates whether particle ensembles in a fractured rock domain may be adequately modeled as an operator-stable plume. If this statistical model applies to transport in fractured media, then an ensemble plume in a fractured rock domain may be modeled using the novel Fokker-Planck evolution equation of the operator-stable plume. These plumes (which include the classical multi-G...

Abstract The shale gas reservoir is regarded as a dual medium consisting of fracture (hydraulic and discrete natural network) rock matrix, the seepage process in matrix fully considered mathematical model flow accordance with Darcy's law was established. results show influence order hydraulic geometry on cumulative production. Compared aperture 10 –4 m, when –5 m –6 production reduced by 88.0% ...

The Hartley transform, a real-valued alternative to the complex Fourier transform, is presented as an efficient tool for the analysis and simulation of earthquake accelerograms. This paper is introduced a novel method based on discrete Hartley transform (DHT) and radial basis function (RBF) neural network for generation of artificial earthquake accelerograms from specific target spectrums. Acce...

The generalized conceptual model for a fractured bedrock aquifer consists of low-permeability matrix blocks separated by highly permeable fractures that act as preferential pathways for ground water flow. The National Research Council (NRC 1996) summarizes three approaches for simulating ground water flow in fractured aquifers. The most common approach is to represent the system with an equival...

This paper reviews the heat transfer model for geothermal reservoirs, fracture network in and numerical of hydraulic fracturing. The first section models, which contain single-porosity model, dual-porosity multi-porosity model; meanwhile mathematical equations porosity are summarized. Then, this introduces reservoirs method computational transfer. In second section, on basis conventional theory...

Hydraulic fracturing is usually employed to create a complex fracture network enhance heat extraction in the development of an enhanced geothermal system. The depends on conduction from rock matrix flowing fractures and convection through network. Therefore, geometries have important influences thermal breakthrough. In this paper, hydro-thermal coupling mathematical model considering establishe...

Under the auspices of the DECOVALEX II international project, the coupled hydromechanical responses, in the fractured volcanic rocks at Sellafield site, to a pump test and shaft sinking were studied. The aim of this paper is to describe the methodology for analysing the hydromechanical responses of a long-term pump test in borehole RCF3 drilled on the centreline of one of the proposed shafts. T...

Fracture orientation is a prominent factor in determining the reservoir fluid flow direction in a formation because fractures are the major paths through which fluid flow occurs. Hence, a true modeling of orientation leads to a reliable prediction of fluid flow. Traditionally, various distributions are used for orientation modeling in fracture networks. Although they offer a fairly suitable est...
