Download or read book Global Trends in X ray Ct Imaging Applications in Petroleum Engineering and the Geosciences from 1984 to 2014 written by Benjamin Wheatall and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: While the use of x-rays originated in medical fields it has expanded through other disciplines. Petroleum and geological sciences are no exception. Beginning in the 1980's, x-ray computed tomography (CT) imaging has become an increasingly powerful tool used to better understand rock and fluid properties. Used by academics and corporations alike, CT imaging creates a more accurate picture of the interactions between rocks and fluids such as water, oil, and gas.This paper explores trends in the history of CT imaging across several geophysical fields. By observing these trends a history of CT imaging can be compiled and further examined. Three main objectives were followed in order to generate insights into CT imaging. The first objective was to build a database that would serve as a representative sample of the papers that make up the current literature of CT imaging in petroleum engineering and the geosciences. The database was limited by the selection criteria and primarily relied on Web of Science to find CT imaging papers. Secondly the CT imaging papers were sorted into various categories such as country of publication and author affiliation. The third objective was to analyze the data and identify geographical institutional affiliations dominating the field of CT imaging in petroleum engineering and the geosciences.CT imaging is a prime example of how technology can transcend disciplinary boundaries. While originating in the medical fields, CT imaging has successfully been adapted to petroleum engineering and the geosciences. This paper documents the impact CT imaging has had from 1984 to 2014 and offers CT imaging as a case study of how a technology created in one field can be a game changer in another.
Download or read book Industrial X Ray Computed Tomography written by Simone Carmignato and published by Springer. This book was released on 2017-10-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.

Download or read book Geological Records of Tsunamis and Other Extreme Waves written by Max Engel and published by Elsevier. This book was released on 2020-07-25 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological Records of Tsunamis and Other Extreme Waves provides a systematic compendium with concise chapters on the concept and history of paleotsunami research, sediment types and sediment sources, field methods, sedimentary and geomorphological characteristics, as well as dating and modeling approaches. By contrasting tsunami deposits with those of competing mechanisms in the coastal zone such as storm waves and surges, and by embedding this field of research into the wider context of tsunami science, the book is also relevant to readers interested in paleotempestology, coastal sedimentary environments, or sea-level changes, and coastal hazard management. The effectiveness of paleotsunami records in coastal hazard-mitigation strategies strongly depends on the appropriate selection of research approaches and methods that are tailored to the site-specific environment and age of the deposits. In addition to summarizing the state-of-the-art in tsunami sedimentology, Geological Records of Tsunamis and Other Extreme Waves guides researchers through establishing an appropriate research design and how to develop reliable records of prehistoric events using field-based and laboratory methods, as well as modeling techniques. - Features a comprehensive overview of the state of the art in tsunami sedimentology and paleotsunami research - Offers advice on the most appropriate mapping, sampling, and analytical approaches for a wide variety of coastal settings and sedimentary environments - Provides methodological details for field sampling and the most important proxy analyses

Download or read book Cyclic and Fatigue Mechanical Behaviors of Bimrocks written by Yu Wang and published by Scientific Research Publishing, Inc. USA. This book was released on 2022-08-31 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a reference book for advanced graduate students and research engineers in rock mass structural mechanics related to civil engineering, mining, etc. The term of bimrocks (bimsoils, SRM, RSA) is used to describe the mixture of fine particles and larger blocks, such as mélanges, coarse pyroclastic rocks, breccias, colluviums and alluviums, fault rocks, and conglomerates, etc. Bimrock is especially different from the general soil and rock material, and the detection of the damage and fracture is still wide open to innovative research. Globally, there is widespread interest in investigating the geomechanical behaviors of bimrocks, such as deformation and strength characteristics, damage and fracture evolution and stability prediction of bimrock construction. However, the meso-structure factors control the whole mechanical properties of bimrocks, the source of the macroscopic deformation phenomenon is the meso-structural changes. During civil or mining engineering construction, the bimrock is often exposed to complex stress disturbance, such as environmental and human-induced loading acting on rock that is cyclic in nature. Typical forms of stress disturbance include blasting vibration, earthquake, excavation, drilling and vehicle loading, etc. Usually, the stress disturbance condition is inferred as a kind of dynamic loading and differs dramatically from those under static loads. Therefore, evaluation of the mesoscopic physical and mechanical properties, together with advanced testing technique, is attractive research topics in its fatigue mechanics. As a result, comprehensive macroscopic and mesoscopic experimental investigations should be conducted to reveal the damage and fracturing mechanical behaviors of bimrock exposed to cyclic and fatigue loads.

Download or read book Proxies in Late Cenozoic Paleoceanography written by C. Hillaire-Marcel and published by Elsevier. This book was released on 2007-05-25 with total page 863 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is the first in a series of two books dedicated to the paleoceanography of the Late Cenozoic ocean. The need for an updated synthesis on paleoceanographic science is urgent, owing to the huge and very diversified progress made in this domain during the last decade. In addition, no comprehensive monography still exists in this domain. This is quite incomprehensible in view of the contribution of paleoceanographic research to our present understanding of the dynamics of the climate-ocean system. The focus on the Late Cenozoic ocean responds to two constraints. Firstly, most quantitative methods, notably those based on micropaleontological approaches, cannot be used back in time beyond a few million years at most. Secondly, the last few million years, with their strong climate oscillations, show specific high frequency changes of the ocean with a relatively reduced influcence of tectonics. The first volume addresses quantitative methodologies to reconstruct the dynamics of the ocean andthe second, major aspects of the ocean system (thermohaline circulation, carbon cycle, productivity, sea level etc.) and will also present regional synthesis about the paleoceanography of major the oceanic basins. In both cases, the focus is the "open ocean leaving aside nearshore processes that depend too much onlocal conditions. In this first volume, we have gathered up-to-date methodologies for the measurement and quantitative interpretation of tracers and proxies in deep sea sediments that allow reconstruction of a few key past-properties of the ocean( temperature, salinity, sea-ice cover, seasonal gradients, pH, ventilation, oceanic currents, thermohaline circulation, and paleoproductivity). Chapters encompass physical methods (conventional grain-size studies, tomodensitometry, magnetic and mineralogical properties), most current biological proxies (planktic and benthic foraminifers, deep sea corals, diatoms, coccoliths, dinocysts and biomarkers) and key geochemical tracers (trace elements, stable isotopes, radiogenic isotopes, and U-series). Contributors to the book and members of the review panel are among the best scientists in their specialty. They represent major European and North American laboratories and thus provide a priori guarantees to the quality and updat of the entire book. Scientists and graduate students in paleoclimatology, paleoceanography, climate modeling, and undergraduate and graduate students in marine geology represent the target audience. This volume should be of interest for scientists involved in several international programs, such as those linked to the IPCC (IODP – Integrated Ocean Drilling Program; PAGES – Past Global Changes; IMAGES – Marine Global Changes; PMIP: Paleoclimate Intercomparison Project; several IGCP projects etc.), That is, all programs that require access to time series illustrating changes in the climate-ocean system. - Presents updated techniques and methods in paleoceanography - Reviews the state-of-the-art interpretation of proxies used for quantitative reconstruction of the climate-ocean system - Acts as a supplement for undergraduate and graduate courses in paleoceanography and marine geology
Download or read book Advances in the Characterization of Industrial Minerals written by G.E. Christidis and published by The Mineralogical Society of Great Britain and Ireland. This book was released on 2011-08-31 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advancement of human civilization has been intimately associated with the exploitation of raw materials. In fact the distinction of the main historical eras is based on the type of raw materials used. Hence, passage from the Paleolithic and Neolithic Age to the Bronze Age is characterized by the introduction of basic metals mainly copper, zinc and tin in human activities; the Iron Age is marked by the use of iron as the predominant metal. The use of metals has increased and culminated with the industrial revolution in the mid-eighteenth century, which marked the onset of the industrial age in the western world. Since then the importance of metals has gradually been surpassed by industrial minerals in the industrialized countries. Industrial minerals are raw materials used by industry for their physical and/or chemical properties. Characterization of industrial minerals is important for their assessment and can be demanding and often complicated. This new volume, co-published by the European Mineralogical Union and the Mineralogical Society of Great Britain & Ireland, is based on papers presented at an EMU-Erasmus IP School which was held in the Technical University of Crete, Chania, Greece. The aim of the School was to describe advances in some of the analytical methods used to characterize industrial minerals and to propose additional methods which are currently not used for this purpose.
