A physically based numerical approach is presented for modeling multiphase flow and transport processes in fractured rock. In particular, a general framework model is discussed for dealing with fracture-matrix interactions, which is applicable to both continuum and discrete fracture conceptualization. The numerical modeling approach is based on a general multiple-continuum concept, suitable for...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...

Abstract Patterns of state formation have crucial implications for comparative economic development. Diamond (1997) famously argued that “fractured land” was responsible China’s tendency toward political unification and Europe’s protracted polycentrism. We build a dynamic model with granular geographical information in terms topographical features the location productive agricultural land to qu...

Due to geological reasons, fractured reservoirs are extremely heterogeneous. Modelling of these reservoirs has so far been considered complex and progress is still inadequate. This paper presents a novel and hybrid method to model discrete fracture networks in naturally fractured reservoirs. It involves investigation and systematic integration of tasks spanning cross-disciplinary areas: geologi...

Internal viewing of the cellular organization of hyphae by scanning electron microscopy is an alternative to observing sectioned fungal material with a transmission electron microscope. To study cytoplasmic organelles in the hyphal cells of fungi by SEM, colonies were chemically fixed with glutaraldehyde and osmium tetroxide and then immersed in dimethyl sulfoxide. Following this procedure, the...

[1] Accurate and efficient simulation of contaminant transport in fractured rock is practically important, yet current approaches suffer from numerical constraints that limit the full inclusion of fracture network properties at the regional scale. We propose a multidimensional transport model, nonlocal in space and time, which describes complex transport behavior in fractured media at regional ...

INTRODUCTION The fracture of front teeth is one of the routine presentations of traumatic injuries. The treatment of a fractured tooth involving the pulp includes root canal therapy and post placement followed by core build-up or by the extraction of the fractured tooth if it is not restorable. CASE PRESENTATION We report a case of an adult male who had traumatized both his maxillary central ...
