Available in PDF, EPUB and Kindle. Book excerpt: The theme of the 31st US Symposium on Rock Mechanics is 'Rock Mechanics contributions and challenges', having as objective the examination and quantification of the progress that has been achieved in addressing the major practical challenges facing the science of rock mechanics and mine design. The 124 papers included in the proceedings cover areas such as: experimental studies (laboratory and field); conceptual, analytical, and numerical modeling; design and construction methods. 35 papers deal with practical mining problems and include information on rock reinforcement technology, blasting, rock bursts, open pit mining, remote sensing and borehole geophysics, mechanical fragmentation, and subsidence. Areas emphasized are coal and metal mine design problems. Other papers deal with the newest computer models, new instruments, fracture mechanics, new laboratory testing techniques, and in situ testing.

Available in PDF, EPUB and Kindle. Book excerpt: (4). The next three papers extend these views by taking a closer look on parameters that govern hydraulic diffusivity in sandstones and other types of rocks. Specific targets addressed are the influence of differential stress on permeability (5), imaging of the fracture geometry (6), and pressure induced variations in the pore geometry (7). Contributions no. 8 to 10 cover investigations of permeability-porosity relationships during rock evolution (8), of the formation, propagation, and roughness of fractures in a plexi-glass block (9), and pressure oscillation effects of two-phase flow under controlled conditions (10). The subsequent four articles focus on diverse modeling approaches. Issues considered are how the geometry and the mechanical behavior of fractures can be characterized by mathematical expressions (11), how the evolution of permeability in a microcracking rock can be expressed by an analytical model (12), deviations from the cubic law for a fracture of varying aperture (13), and the numerical simulation of scale effects in flow through fractures (14). Three further papers refer to in situ observations, being related to topics as the assessment of in situ permeability from the spatio temporal distribution of an aftershock sequence (15), to the scale dependence of hydraulic pathways in crystalline rock (16), and to the significance of pore pressure - stress coupling in deep tunnels and galleries (17).

Available in PDF, EPUB and Kindle. Book excerpt: Understanding physical, chemical, and mechanical processes and properties of a single fracture is fundamental to many processes on Earth, particularly hydrogeological phenomena across many scales. However, classical and widely used theories governing flow and transport processes are founded on the parallel plates model; this ignores the complex morphology of natural fracture. To fill this gap, I have investigated the role of fracture morphology on flow (permeability), transport (dispersion coefficients and other surrogate parameters), and mechanical (stiffness) properties through complementary theoretical analysis and computational experiments. The collection of single fractures used in this dissertation included natural fractures mapped through high-resolution x-ray computed tomography and synthetic ones generated through a model which produces fractures with fractal properties. I developed a modified Local Cubic Law (MLCL) allowing for fracture roughness, tortuosity, and weak inertial force to improve the prediction of fluid flow process. The validation of the MLCL was tested by comparing volumetric flux from solving the Navier-Stokes equations to that from the MLCL. Secondly, the effect of fracture roughness on the non-Fickian or anomalous transport was studied through an ensemble of 2D direct transport simulations. Moreover, I was able to show, analyze, and predict the transition from non-Fickian to Fickian transport by developing a quasi-3D particle tracking algorithm. Finally, I developed a fracture deformation model. The co-evolving permeability and stiffness were then determined through the MLCL and strain-stress relationship based on the deformation model. Through my dissertation research, I confirm that the classical LCL fails to predict bulk permeability or volumetric flux (errors up to 41%). The MLCL performs better in characterizing local and effective fluid flow processes, with only 4% error. Moreover, I find out that fracture roughness leads to non-Fickian transport, and that the degree of non-Fickian behavior depends directly on the fracture roughness. Additionally, I theoretically derive asymptotic time and lengths scales for distinguishing non-Fickian from Fickian transport for the simplified Poiseuille and Hagan-Poiseuille flow fields. The increasing scales drives non-Fickian transitioning into Fickian transport even though the presence of persistent intermittent velocity structure. Lastly, I show that scaling between fracture permeability and normal stiffness depends on both fracture roughness and aperture correlation length, indicating a potentially universal model that can describe this behavior.

Applications are connected with dynamics large scale processes, blast waves and with structure of the Earth's crust. Part II focuses on the effects of fluid saturation of pores and transfer phenomena. Applications are connected with seismic waves, oil and gascondensate recovery, explosion works, physico-chemical processes.

This book was released on 2015-09-23 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase Fluid Flow in Porous and Fractured Reservoirs discusses the process of modeling fluid flow in petroleum and natural gas reservoirs, a practice that has become increasingly complex thanks to multiple fractures in horizontal drilling and the discovery of more unconventional reservoirs and resources. The book updates the reservoir engineer of today with the latest developments in reservoir simulation by combining a powerhouse of theory, analytical, and numerical methods to create stronger verification and validation modeling methods, ultimately improving recovery in stagnant and complex reservoirs. Going beyond the standard topics in past literature, coverage includes well treatment, Non-Newtonian fluids and rheological models, multiphase fluid coupled with geomechanics in reservoirs, and modeling applications for unconventional petroleum resources. The book equips today’s reservoir engineer and modeler with the most relevant tools and knowledge to establish and solidify stronger oil and gas recovery. Delivers updates on recent developments in reservoir simulation such as modeling approaches for multiphase flow simulation of fractured media and unconventional reservoirs Explains analytical solutions and approaches as well as applications to modeling verification for today’s reservoir problems, such as evaluating saturation and pressure profiles and recovery factors or displacement efficiency Utilize practical codes and programs featured from online companion website
