This book covers exploration and evaluation practices for various types of complex reservoirs, and summarizes a series of practical and effective techniques and methods. For example, it shows how, by integrating multiple types of new logging technology, complex reservoir petrophysics evaluation can be performed using high-precision core experiment data and quantitative logging interpretation; and demonstrates how the technology of sporopollen assemblage and palynofacies analysis can improve the time precision of sequence stratigraphy and the quantitative study level of sedimentary facies, respectively. It discusses how reservoir lateral prediction and vertical resolution can be substantially improved by integrating fracture prediction and geostatistical inversion; and presents innovative log interpretation charts for the lithological identification of metamorphic rocks, e.g. GR-DEN crossplot and Impedance-Resistivity crossplot. To support the main content, the book features a wealth of high-resolution, thin- section images, quantitative illustrations of palynofacies composition, multi-property overlapping map set and quantitative tables. It offers an essential reference guide for researchers in geological exploration and evaluation, and will also appeal to a broad readership, from engineering technicians to advanced graduate students in related areas.

The book covers all aspects of field development plan processes, from reserve estimations to economic analyses. It shows readers in both the oil and gas industry and in academia how to prepare field development plans in a straightforward way, and with substantially less uncertainty.
Was genau ist das Anthropozan und wie ist es entstanden? Welche Krafte wirken in ihm? Wohin fuhrt es die globale Zivilisation? Hat das Anthropozan die Klimakrise herbeigefuhrt? Gibt es durch das Anthropozan praktisch keine reale Nachhaltigkeit mehr? Was kann aus den vielen Krisen im Anthropozan gelernt werden? Diese Fragestellungen werden gut lesbar und anschaulich auf dem aktuellen Stand der Dinge behandelt. Auf dieser Basis stellt der Autor einen detaillierten Plan zur Abschwachung der Klimakrise vor, der durch einzelne Staaten verwirklicht werden koennte. Ausserdem prasentiert er ein Konzept zur Erzielung realer Nachhaltigkeit und begrundet, warum das Anthropozan als neues Erdzeitalter ausgerufen werden sollte. In diesem Kontext geht der Autor auch auf die Coronavirus-Pandemie ein. Das Buch schliesst mit der Aufforderung, die "zweite Aufklarung" voranzutreiben. Sie ist notwendig, um das noch verbleibende Zeitfenster von wenigen Dekaden zu nutzen, damit das Anthropozan zukunftsfahig wird.
This book aims to inform policy-makers, engineers and earth scientists about the current and emerging role of geophysics in addressing environmental processes, assessments, and policy directions related to new and existing dams and levees. Until now geophysics has concentrated on characterization and remediation of dams and levees, but now the field is changing our understanding on the influence of natural processes (e.g., floods, dissolution) and human activities in the design, and management of these structures. This monograph includes advances in the following fields of Dams and Levees studies: * New insights from small and mid-sized laboratory experiments* Integrated methods electromagnetic, seismic, potential methods* Inverse modeling approaches* Statistical considerations* Monitoring of processes attending aging structures * Hazard monitoring* Risk Analysis
Papers cover topics including: physical modelling facilities; experimental advances; seismic experimental advances; education; soil behaviour; offshore systems; cold regions; geoenvironment; dynamics; earthquake effects; and strategies for disaster reduction.
This book examines picroilmenites and their ferromagnetic behavior in the kimberlites from the Yakut diamondiferous province. Picroilmenites are minerals used to identify the location of diamonds. The author shows a solid interpretation of the magnetic-mineralogical analysis of ferromagnetic minerals based on a large number of experimental data and modeling of the magnetic state. He also presents the problems of the variability of the composition of picroilmenites from various kimberlite pipes. Furthermore, this book proposes a method to estimate the distribution of the decay structures dimensions, according to the thermomagnetic analysis and coercive spectra of titanomagnetites with the magnetite-ulvospinel decomposition structures. This book will be useful for students and researchers working in the field of rock magnetism, as well as geologists and geophysicists.
The story of one citizen's fight to preserve a US stake in the future of clean energy and the elements essential to high tech industries and national defense. American technological prowess used to be unrivaled. But because of globalization, and with the blessing of the U.S. government, once proprietary materials, components and technologies are increasingly commercialized outside the U.S. Nowhere is this more dangerous than in China's monopoly of rare earth elements-materials that are essential for nearly all modern consumer goods, gadgets and weapons systems. Jim Kennedy is a retired securities portfolio manager who bought a bankrupt mining operation. The mine was rich in rare earth elements, but he soon discovered that China owned the entire global supply and manufacturing chain. Worse, no one in the federal government cared. Dismayed by this discovery, Jim made a plan to restore America's rare earth industry. His plan also allowed technology companies to manufacture rare earth dependent technologies in the United States again and develop safe, clean nuclear energy. For years, Jim lobbied Congress, the Pentagon, the White House Office of Science and Technology, and traveled the globe to gain support. Exhausted, down hundreds of thousands of dollars, and with his wife at her wits' end, at the start of 2017, Jim sat on the edge of victory, held his breath and bet it all that his government would finally do the right thing. Like Beth Macy's Factory Man, this is the story of one man's efforts to stem the dehumanizing tide of globalization and Washington's reckless inaction. Jim's is a fight we need to join.
This is the first book that analyses the future raw materials supply from the demand side of a society that chiefly relies on renewable energies, which is of great significance for us all. It addresses primary and secondary resources and substitution, not only from technical but also socioeconomic and ethical points of view. The "Energiewende" (Energy Transition) will change our consumption of natural resources significantly. When in future our energy requirements will be covered mostly by wind, solar power and biomass, we will need less coal, oil and natural gas. However, the consumption of minerals, especially metallic resources, will increase to build wind generators, solar panels or energy storage facilities. Besides e.g. copper, nickel or cobalt, rare earth elements and other high-tech elements will be increasingly used. With regard to primary metals, Germany is 100 % import dependent; only secondary material is produced within Germany. Though sufficient geological primary resources exist worldwide, their availability on the market is crucial. The future supply of the market is dependent on the development of prices, the transparency of the market and the question of social and ethical standards in the raw materials industry, as well as the social license to operate, which especially applies to mining. The book offers a valuable resource for everyone interested in the future raw material supply of our way of life, which will involve more and more renewable energies.
Uranium isotopes (238U/235U) have emerged as a proxy to reconstruct the redox conditions of the Earth's oceans and atmosphere based upon the large isotopic fractionation between reduced U(IV) and oxidized U(VI). Variations in 238U/235U, particularly when recorded in carbonate sediments, can track global trends in marine oxygenation and de-oxygenation. It is unique from other proxies because reduction primarily occurs at the sediment-water interface, and this sensitivity makes U isotopes especially relevant for the habitability of benthic animals. This Element covers the background, methods, and case studies of this promising tool for understanding Earth's environmental transitions, as rapid development continues to refine the accuracy of interpretations of 238U/235U records.
With respect to the vital work of maintaining and increasing much needed petroleum reserves within the continental United States, the Southeast is intriguing because it has been under-explored for many years at the expense of far more promising areas such as the Gulf Coast. While critics may contend that the overall geology of the Southeastern United States is unfavorable for commercial accumulations of hydrocarbons, the occurrence of the oil seeps in Georgia and the oil and gas shows reported in wells drilled in North Carolina, suggests otherwise. This volume introduces new evidence and compiles and re-examines data which argues for increased oil and gas exploration in the region.
A significant step forward in the world of earth observation was made with the development of imaging spectrometry. Imaging spectrometers measure reflected solar radiance from the earth in many narrow spectral bands. Such a spectroscopical imaging system is capable of detecting subtle absorption bands in the reflectance spectra and measure the reflectance spectra of various objects with a very high accuracy. As a result, imaging spectrometry enables a better identification of objects at the earth surface and a better quantification of the object properties than can be achieved by traditional earth observation sensors such as Landsat TM and SPOT. The various chapters in the book present the concepts of imaging spectrometry by discussing the underlying physics and the analytical image processing techniques. The second part of the book presents in detail a wide variety of applications of these new techniques ranging from mineral identification, mapping of expansive soils, land degradation, agricultural crops, natural vegetation and surface water quality.

The 2010 tsunamis generated in Haiti, Chile, and Indonesia caused various damage on the coasts. In the past, the 1755 Lisbon, 1964 Alaska, and 2003 Algeria earthquakes also generated damaging tsunamis. This volume contains an introduction and 18 papers, mostly presented at the 25th International Tsunami Symposium held 1-4 July 2011. They report the above tsunamis and discuss tsunami DART observations, warning systems, risk management in the Pacific, modelling of earthquake and landslide tsunamis, and probabilistic tsunami hazard assessment.
The mining engineer and petrologist Frederick Henry Hatch (1864 1932) left the Geological Survey of Great Britain in 1892, relocating to South Africa. He worked for De Beers and with John Hays Hammond for Cecil Rhodes, finding important new gold fields in Matabeleland and Mashonaland. Control of the gold mines was a significant factor in the tension between Dutch and English settlers that would result in the Second Boer War in 1899. Prior to this, Rhodes and Hammond were behind the abortive Jameson Raid, but Hatch had returned to England briefly and was not implicated. This 1895 work, written with South African mining engineer J. A. Chalmers, reveals the extent of gold reserves in the Transvaal, and the engineering skills needed to exploit them. It deals with geological, economic and legal aspects of the mining industry, remaining of interest to historians of South Africa and the British Empire.
Of Earth, For Earth is a 116-page full-colour, hardcover book, consisting of dialogue between artists, community representatives, industrialists and educators. It also contains images from the exhibition of the same name, and many other artists have contributed to it with images and texts. It aims to inspire debate about human interactions with the Earth, while our consumption of resources grows ever larger and the environments on which we depend face an uncertain future. This book speaks to our sense of belonging to place, time, natural and cultural heritage. It describes the geologically grounded and contested places in which mining inspires our relationship with Earth and interrogates our commitment to change. Through dialogue and debate, perhaps we may unearth mechanisms to carve out a more sustainable relationship with the Earth while maintaining access to the resources that will support the global population.

Robert Jameson (1774 1854) was a renowned geologist who held the chair of natural history at Edinburgh from 1804 until his death. A pupil of Gottlob Werner at Freiberg, he was in turn one of Charles Darwin's teachers. Originally a follower of Werner's influential theory of Neptunism to explain the formation of the earth's crust, and an opponent of Hutton and Playfair, he was later won over by the idea that the earth was formed by natural processes over geological time. He was a controversial writer, accused of bias towards those who shared his Wernerian sympathies such as Cuvier, while attacking Playfair, Hutton and Lyell. He built up an enormous collection of geological specimens, which provided the evidence for his System of Mineralogy, first published in 1808 and here reprinted from the second edition of 1816. Volume 1 deals with what Jameson terms 'earthy minerals', including diamonds, rubies and feldspar.

The thirty papers in this 1986 volume review the scientific knowledge of the nature of flint and chert at this time. These papers were presented at a 1983 interdisciplinary and international conference on flint and other cherts. Each contribution has been meticulously assessed and edited prior to publication. This collection is principally concerned with the geology and geochemistry of flint in European chert. Topics include the origin of flint; scanning electron microscopy of surface textures; and the behaviour of flint under periglacial conditions. There is a companion volume, edited by G. de G. Sieveking and M. B. Hart, on the archaeological uses of flint.
This textbook employs a technical and quantitative approach to explain subsurface hydrology and hydrogeology, and to offer a comprehensive overview of groundwater-related topics such as flow in porous media, aquifer characterization, contaminant description and transport, risk assessment, and groundwater remediation. It describes the characterization of subsurface flow of pristine and polluted water and provides readers with easily applicable tools for the design of water supply systems, drinking-water source protection, and remediation interventions. Specific applications range from groundwater exploitation as a drinking water supply to the remediation of contaminated aquifers, from the definition and safeguarding of drinking-water sources to the assessment of human health risks in connection with groundwater contamination events. The book represents an ideal learning resource for upper-undergraduate and graduate students of civil engineering, environmental engineering, and geology, as well as practitioners in the fields of water resource management and environmental protection who are interested in groundwater engineering and technical hydrogeology.
This text examines the environmental setting and resulting phosphorites that formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geological record. Sedimentary phosphate deposits (phosphorites) are of major commercial significance, being one of the world's most important non-renewable resources, and essential in the manufacture of phosphate fertilizers and phosphate based chemicals. An oceanographic perspective is provided by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This is the third of four planned reference volumes that together will cover the achievements of the International Geological Correlation Programme Project 156 (Phosphates) during the ten years of the project's existence. As with the previous volumes, this will form an essential work of reference for geologists and mining engineers interested in the search for, and exploitation of, phosphate rock deposits.
The Ordos Basin: Sedimentological Research for Hydrocarbons Exploration provides an overview of sedimentological approaches used in the lacustrine Ordos Basin (but also applicable in other marine and lacustrine basins) to make hydrocarbon exploration more efficient. Oil exploration is becoming increasingly focused on tight sandstone reservoirs and shales. The development of these reservoirs, particularly regarding the sedimentary processes and the resulting sediments, are still poorly understood. Exploration and exploitation of such reservoirs requires new insights into the lateral and vertical facies changes, and as already indicated above, the knowledge surrounding facies and how they change in deep-water environments is still relatively unclear.
With the eye of a professional scientist and the passion of a
dedicated amateur, E. C. Pielou conducts a guided tour of fresh
water on its course through the natural world. As the world's
supply of clean, fresh water continues to dwindle, it becomes
increasingly important to understand the close connection between
water and all forms of life. Pielou's fascination with fresh water
gives us a "natural history" that is remarkable and surprising.
Humanity's ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance. This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life cycle of a mine and after its closure are addressed, with an emphasis on sustainable and "green" mining. The central scientific theme of the book is to place the extraordinary variability of mineral deposits in the frame of fundamental geological processes. The book is written for earth science students and practicing geologists worldwide. Professionals in administration, resource development, mining, mine reclamation, metallurgy, and mineral economics will also find the text valuable. "Economic Geology" is a fully revised translation of the the fifth edition of the German language text "Mineralische und Energie-Rohstoffe."

Diamonds are a multi-billion dollar business involving some of the world's largest mining companies, a million and a half artisanal diggers, more than a million cutters and polishers and a huge retail jewellery sector. But behind the sparkle of the diamond lies a murkier story, in which rebel armies in Angola, Sierra Leone and the Congo turned to diamonds to finance their wars. Completely unregulated, so-called blood diamonds became the perfect tool for money laundering, tax evasion, drug-running and weapons-trafficking. Diamonds brings together for the first time all aspects of the diamond industry. In it, Ian Smillie, former UN Security Council investigator and leading figure in the blood diamonds campaign, offers a comprehensive analysis of the history and structure of today's diamond trade, the struggle for effective regulation and the challenges ahead. There is, he argues, greater diversification and competition than ever before, but thanks to the success of the Kimberley Process, this coveted and prestigious gem now represents a fragile but renewed opportunity for development in some of the world's poorest nations. This part of the diamond story has rarely been told.
