Book Synopsis The Internal Structure of Fault Zones by : Christopher A. J. Wibberley
Download or read book The Internal Structure of Fault Zones written by Christopher A. J. Wibberley and published by Geological Society of London. This book was released on 2008 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faults are primary focuses of both fluid migration and deformation in the upper crust. The recognition that faults are typically heterogeneous zones of deformed material, not simple discrete fractures, has fundamental implications for the way geoscientists predict fluid migration in fault zones, as well as leading to new concepts in understanding seismic/aseismic strain accommodation. This book captures current research into understanding the complexities of fault-zone internal structure, and their control on mechanical and fluid-flow properties of the upper crust. A wide variety of approaches are presented, from geological field studies and laboratory analyses of fault-zone and fault-rock properties to numerical fluid-flow modelling, and from seismological data analyses to coupled hydraulic and rheological modelling. The publication aims to illustrate the importance of understanding fault-zone complexity by integrating such diverse approaches, and its impact on the rheological and fluid-flow behaviour of fault zones in different contexts.

Book Synopsis Predicting the Internal Structure of Fault Zones in Basalt Sequences, and Their Effect on Along- and Across-fault Fluid Flow by : Rachael Ellen
Download or read book Predicting the Internal Structure of Fault Zones in Basalt Sequences, and Their Effect on Along- and Across-fault Fluid Flow written by Rachael Ellen and published by . This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the architecture and fluid flow potential of fault zones in basalt sequences has intensified over recent years, due to their applications in the hydrocarbon industry and CO2 storage. In this study, field mapping is combined with micro-structural analyses and flow modelling to evaluate fault growth, evolution, fluid-rock interactions, and permeability changes over time in faults in basalt sequences. Twelve brittle fault zones cutting basalt sequences in the North Atlantic Igneous Province were studied. This study finds that fault architecture is ultimately controlled by displacement and juxtaposition. Self-juxtaposed faults (i.e. basalt faulted against itself) are characterised by wide zones of brecciation, cataclasis, fracturing, mineralisation and alteration. Non self-juxtaposed faults (i.e. basalt faulted against an inter-lava unit) are characterised by relatively narrow principal slip zones, filled with clay smears or clay-rich gouge derived from inter-lava beds. This study also finds that brittle deformation of basalts at the grain scale is mineralogy dependent. Fe-Ti oxides and pyroxenes deform by intragranular fracturing and grain size reduction, whereas olivines and feldspars are susceptible to replacement by clay and zeolites. Fault rock bulk chemistries are likely to differ from their host rocks, and this is controlled by secondary mineral formation, with zeolite and clay minerals playing an important role. Flow modelling in this study shows that controls on along- and across-fault fluid flow can significantly change fault zone bulk permeability over time, as a result of mineralisation and alteration of the fault zone as it evolves. The results from this study are used to propose a model for how fault strength, fault-related alteration, and permeability change over time in fault zones in basalt sequences. Results highlight the impact that fault-related alteration could have on CO2 storage. A predictive model for fault structure at depth, developed from this study's findings, is presented for fault zones in basalt sequences, which has particular relevance to the hydrocarbon and CO2 industry.

Book Synopsis Faulting, Fault Sealing and Fluid Flow in Hydrocarbon Reservoirs by : G. Jones
Download or read book Faulting, Fault Sealing and Fluid Flow in Hydrocarbon Reservoirs written by G. Jones and published by Geological Society Publishing House. This book was released on 1998 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation "Compared with many other areas of the petroleum geosciences, studies of the structural controls on fluid flow in hydrocarbon reservoirs are in their infancy. As hydrocarbon reserves have become depleted and the oil industry has become more competitive, the need to cut costs by optimizing production and predicting the occurrence of subtle traps has highlighted the importance of information on the way in which faults and fractures affect fluid flow. Structural geologists are now having to provide answers to questions such as: Are hydrocarbons likely to have migrated into (or out of) the trap? What is the likely height of hydrocarbons that a fault can support? Is it likely that compartments which have not been produced exist within a field and will therefore require further drilling?" "This volume aims to find answers to these questions."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved.
Book Synopsis Rock Fractures and Fluid Flow by : National Research Council
Download or read book Rock Fractures and Fluid Flow written by National Research Council and published by National Academies Press. This book was released on 1996-08-27 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific understanding of fluid flow in rock fracturesâ€"a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storageâ€"has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
Book Synopsis Living on an Active Earth by : National Research Council
Download or read book Living on an Active Earth written by National Research Council and published by National Academies Press. This book was released on 2003-09-22 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline.
Download or read book Tectonic Faults written by Mark R. Handy and published by MIT Press. This book was released on 2007 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists examine tectonic faulting on all scales--from seismic fault slip to the formation of mountain ranges--and discuss its connection to a wide range of global phenomena, including long-term climate change and evolution. Tectonic faults are sites of localized motion, both at the Earth's surface and within its dynamic interior. Faulting is directly linked to a wide range of global phenomena, including long-term climate change and the evolution of hominids, the opening and closure of oceans, and the rise and fall of mountain ranges. In Tectonic Faults, scientists from a variety of disciplines explore the connections between faulting and the processes of the Earth's atmosphere, surface, and interior. They consider faults and faulting from many different vantage points--including those of surface analysts, geochemists, material scientists, and physicists--and in all scales, from seismic fault slip to moving tectonic plates. They address basic issues, including the imaging of faults from Earth's surface to the base of the lithosphere and deeper, the structure and rheology of fault rocks, and the role of fluids and melt on the physical properties of deforming rock. They suggest strategies for understanding the interaction of faulting with topography and climate, predicting fault behavior, and interpreting the impacts on the rock record and the human environment. Using an Earth Systems approach, Tectonic Faults provides a new understanding of feedback between faulting and Earth's atmospheric, surface, and interior processes, and recommends new approaches for advancing knowledge of tectonic faults as an integral part of our dynamic planet.

Book Synopsis Integrated Fault Seal Analysis by : S. Ogilvie
Download or read book Integrated Fault Seal Analysis written by S. Ogilvie and published by Geological Society of London. This book was released on 2020-08-03 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faults commonly trap fluids such as hydrocarbons and water and therefore are of economic significance. During hydrocarbon field development, smaller faults can provide baffles and/or conduits to flow. There are relatively simple, well established workflows to carry out a fault seal analysis for siliciclastic rocks based primarily on clay content. There are, however, outstanding challenges related to other rock types, to calibrating fault seal models (with static and dynamic data) and to handling uncertainty. The variety of studies presented here demonstrate the types of data required and workflows followed in today’s environment in order to understand the uncertainties, risks and upsides associated with fault-related fluid flow. These studies span all parts of the hydrocarbon value chain from exploration to production but are also of relevance for other industries such as radioactive waste and CO2 containment.
Book Synopsis Involvement of Fluids in Earthquake Ruptures by : Teruo Yamashita
Download or read book Involvement of Fluids in Earthquake Ruptures written by Teruo Yamashita and published by Springer. This book was released on 2017-07-24 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book furnishes state-of-the-art knowledge about how earthquake faulting is coupled with fluid flow. The authors describe the theoretical background of modeling of faulting coupled with fluid flow in detail. Field and laboratory evidence to suggest the fluid involvement in earthquake faulting is also carefully explained. All of the provided information constitutes together a basic framework of the fault modeling for a comprehensive understanding of the involvement of fluids in earthquake ruptures. Earthquake generation is now widely believed to be significantly affected by high-pressure fluid existing at depths. Consequently, modeling study of earthquake faulting coupled with fluid flow is becoming increasingly active as a field of research. This work is aimed at a wide range of readers, and is especially relevant for graduate students and solid-earth researchers who wish to become more familiar with the field.

Book Synopsis Fault Zone Architecture and Deformation Mechanics of Normal Faults in Poorly Lithified Sediments, Miri - Malaysia by : Silvia Sosio de Rosa
Download or read book Fault Zone Architecture and Deformation Mechanics of Normal Faults in Poorly Lithified Sediments, Miri - Malaysia written by Silvia Sosio de Rosa and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault zones are mechanical and hydrological heterogeneities in Earth's upper crust, however, the internal properties that cause heterogeneity, their three-dimensional variations, and the fundamental processes that lead to these variations are poorly understood. The hydraulic behaviour of faults at depth plays an important role in the exploration and production of hydrocarbons, as in several other subsurface engineering applications. Faults can act as conduits, barriers and combined conduit-barrier systems to fluid flow, depending on their petrophysical properties, on their internal structure and stress state. The degree to which a fault will impede fluid flow is only as great as its most permeable point. Producing reliable predictions of cross-fault and up-fault fluid flow requires an understanding of the processes that determine areas of the fault surface containing transmissible fault rocks. A field site in Miri, Jalan Mukag outcrop, was selected because it offers excellent 3D outcrops of normal faults in soft siliciclastic sediments, and gives the opportunity to investigate fault architecture both along-strike and down-dip. Weak-seal areas for cross-fault fluid flow along the fault zone exposures are identified combining detailed mapping of the fault zone architecture, analyses of the fault rock facies and geostatistical characterization (variograms) of variation in along-strike fault-core thickness. Processes that express the accumulation of of strain in the fault core (slip surfaces, boudinage and grain-scale mixing) are analysed because of their implications in terms of cross-fault fluid flow. The interaction between these processes in the fault core may or may not lead to complete mesoscale and grain-scale mixing, thus potentially induce changes in the capillary entry pressure of the fault rocks. Deformation mechanisms and geochemical processes that affect the fault zone are identified through petrographic, microstructural and mineralogical analysis,and they are used to infer along-fault fluid flow history and implications for cross-fault fluid flow.
