...1. INTRODUCTION Hydraulic fracturing technique is widely used in the petroleum industry for stimulating wells. Another application of the technology is drill cuttings reinjection, in which huge fractures are created in formations around wellbores to contain the slurrified solid waste produced...

... ABSTRACT: This paper presents a three-dimensional, geometric-mechanical, hierarchical, stochastic model of natural rock fracture systems. In the model, fracture systems are generated through superposition of hierarchically related sets, created via stochastic methods that reflect inherent...

... has found that half the earthquakes in The Geysers field seem to be associated with cold water injection [2]. The mechanism by which seismicity occurs is well understood namely, shear slip on natural fractures resulting from a reduction in effective stress acting across the fracture. The magnitude...

... Hard Rock Laboratory in southern Sweden [7]. 2.2. Fractured rock mass model The rock mass at Äspö HRL in the vicinity of the test site is typical of the granitic rock masses found in the Scandinavian Shield. It contains several joint sets that vary in both trace length and fracture frequency...

...1. INTRODUCTION Coupled thermal and poromechanical processes play an important role in many geomechanics problems such as borehole stability analysis and studies of initiation and propagation of hydraulic fractures. Thermal effects, as well as poromechanical effects, can greatly change the stresses...

...1. INTRODUCTION Shear dilatation is recognized as a mechanism that can enhance permeability of fluid-driven shear fractures. In contrast to the conventional tensile or opening mode fractures in which the fracture is kept open by an internal pressure that exceeds the minimum stress, the coupling...

Blast effects and site conditions were observed seismically and photographically to provide detailed information concerning rock heave, surface fracturing...

... of energy that remains in the object after the collision is totally dependent on its deformation characteristics. Some energy loss as heat and sound from the impact, but the elastic properties and strength of the objects dictate the energy stored or lost in fracturing of the object. A parameter known...

...1. INTRODUCTION Coupled thermal-mechanical behavior of fractured rocks is an important consideration in the design of civil engineering works, such as slopes, underground storage caverns, and nuclear waste repositories. A numerical method useful in such a consideration is the three-dimensional...
