This book is intended to give an introduction to sedimentology and petroleum geology at undergraduate level. These two subjects have been treated together because of the close links between sedimen tology as an academic dicipline, petroleum geology, which is the application of sedimentology, and a number of other aspects of petroleum exploration and production. The oil industry ist by far the most important employer of sedimentologists and the lively interaction that takes place between the academic community and the research laboratories and exploration departments of the oil industry has been very fruitful for both parties. Our knowledge of sedimentary basins now depends to a very large extent on data obtained by commercial petroleum exploration. Studies of actual rocks in outcrops, particularly if they are extensive, will always be important for sedimentologists, but subsurface data like seismic sections and well logs provide us with in much information on the three-dimensional distribution of facies that we could not otherwise obtain. Subsurface techniques are certainly important for pe troleum geologists, but also other sedimentologists should be able to use subsurface data. I have therefore included elementary intro ductions to the use of well logs and seismic methods in this book, with fundamentals of external controls on sedimentation such as basin subsidence and sea level changes. I have tried to present the state of knowledge at this level without referring to the original research papers except when specific data are quoted or used in illustrations.
Seldom if ever in recent history has a single technological advance made such sweeping changes in our lives as has the advancement of the digital computer. As you probably are aware, the computer itself is not a brand-new device. What is new (and growing every day) is the percentage of the population that is using computers in business and personal environments. The personal computer's popularity is growing by leaps and bounds primarily because of its availability in a small and relatively inexpensive package (several hundred dollars), placing it well within the reach of many families and small businesses. Software to perform financial analysis, solve inventory prob lems, or just have fun with is readily available and reasonably priced, thereby absolving inexperienced users from the burdens of programming and the technical complexities associated with it. The typical user in this scenario derives much of the benefit and experiences few of the disadvantages. Yet, as expected, the solving of a problem often creates problems, as will be discussed. Training and development personnel, like most other profes sionals, have not been immune to the onslaught of personal and business computers. Computer-aided and computer-managed instructional techniques (Le., CAl and CMI) are common phrases today in the realm of training and development."
Every little wiggle has a meaning all its own. This is our underlying faith, that details of seismic waveshapes can tell us the details of the nature of the earth. But their voices are obscured by many irrelevancies. They speak in a high-noise environment, and we have been able to decipher only a small portion. However, things are looking up: better tech niques are lessening the irrelevancies, and we are learning to read. In exploration of unknown areas, determining the nature of the rocks present is often the difficult aspect. Most of the properties of rocks that can be measured at a distance are not distinctive enough to identify the rock unambiguously. Con ventionally, seismic data are used to determine aspects of the structure. Stratigraphic pictures are inferred from the struc ture, the nature of rocks exposed for examination in the sur rounding area, and regional concepts. Three points make seismic stratigraphy feasible now: (1) we have better data quality, (2) we have begun to sys tematize analysis procedures, and (3) we believe in the geologic significance of waveshape details."
This book has its origins in a resolution passed by the Economic and Social Council of the United Nations in July 1975 requesting the Secretary-General to prepare a 10 to 15 year evaluation of the prospects for copper. The investigation was carried out by the Centre for Natural Resources, Energy and Transport, with the help of consultants, and the results summarized in a report submitted to the Committee on Natural Re sources, a subsidiary body of the Economic and Social Council, in May 1977. This book presents the findings of that investigation in greater detail, draws out the impli cations of those findings more fully, and describes the methodology employed more completely than was possible in the earlier report. It also incorporates the results of additional work carried out by the authors since the spring of 1977 so as to take into account recent developments as well as comments received from the participants at the meeting of the Committee on Natural Resources where the summary paper was re viewed. Although all three authors are collectively, and individually, responsible for the whole book, Mr. Wolfgang Gluschke assumes a special responsibility for Chapters IV, V and VI, Mr. Joseph F. Shaw for Chapters I, II, and VIII, and Mr. Bension Varon for Chapters III and VII. The work on the book was undertaken under the general supervision and guidance of Mr. Varon, then Assistant Director ofthe United Nations Centre for Natural Resources, Energy and Transport."
The International Conference on Geological Information represents the first major attempt to bring together geoscience information specialists from allover the world. The purpose of the conference was to assess the current state-of the-art in geoscience information from both the regional and functional point of view. It was hoped that the conference could take steps to bring about increased international cooperation and collaboration in the field of geological information. The papers ranged over the whole spec trum of documentation from primary publishing back to the user, including data. Perhaps a keyword for the conference might be "cooperation." The idea of, and need for, cooperation was stressed in almost every talk. The final panel session was devoted to a discussion on the formation of a proposed International Association for Geological Information. Despite the growing pressure on information managers, stimulated by increasing international activities in geology, the global perspective of plate tectonics and worldwide concern for the availability of non-renewable resources, there does not exist an international organisation specifi cally concerned with geological information. Delegates agreed that there was no need for a new professional society of individuals but that a federation or similar organisation might be desirable. In the final session it became apparent that if the geological information community is to make the best use of all the systems and developments available there is very clearly a need to know what exists in all these areas at present. An urgent task is to identify these systems."
In this course we shall assume that all participants are familiar with the essentials of seismic prospecting. Thus A the rudiments of the field work -- spreads, sources, arrays B and digital recording -- are assumed known. So also are the C rudiments of processing -- such processes as gain recovery, D filtering, deconvolution, velocity analysis, and display. E Just as important, we shall assume that all participants F have some feeling for the realities of seismic work -- in the l(B) field, under real conditions. Elementary signal theory and the basic techniques of interpretation are also assumed known. However, for certainty, the following pre-course notes include sections reviewing basic signal theory, geophysical aspects of interpretation, and geological aspects of interpretation. These reviews are not intended to be comprehensive. Their function is solely to cover, with the minimum possible discussion, the essential features which will be assumed to be known in the course. None of the course time will be spent on the material of these pre-course notes. Participants are advised that they will not derive full benefit from the course if this background is not known. Most course participants will be already familiar with this material, and will need to do little more than read it through. If, before the course, any participant requires further discussion of signal theory in the same non-rigorous style, he will find it in other writings of the present author, particularly: "Wiggles", Journal of the CSEG, December 1965, pp.l3-43.
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.
From its humble beginning in the late 19th century when Henry Ford s first car was designed to run on ethanol biofuel production has been on the rise with more than 26 billion liters produced in the U.S. in 2007. Ethanol made from biomass (rather than grains) holds great promise, including numerous economic and environmental benefits. However, the adverse interactions of energy, climate, food, and soil quality cannot be ignored. In eight concise chapters, Soil Quality and Biofuel Production presents a state-of-the-knowledge review of soil properties and processes negatively impacted by crop residue removal. It outlines the ecological consequences of biofuels and evaluates land use in the production of raw material for biofuel. The book then spotlights pressing issues related to corn and cellulosic ethanol and also soil erosion. It offers advice for achieving economic balance in the competition for arable land between food and biofuel along with residue harvest management techniques. A thought-provoking discussion of the opportunities and challenges that biofuel presents rounds out the book s coverage. The logistics of producing biomass in a sustainable manner remain a major challenge and will continue to be so for the foreseeable future. Serious questions linger concerning viable sources of biofuel feedstock, competition for resources needed to produce biomass, and energy output/input ratios. Soil Quality and Biofuel Production provides environmental scientists and agricultural engineers with the knowledge they need to address them.
Metals in the earth's crust are very unevenly distributed and, traditionally, a small number of ore deposits, districts or countries have dominated the world supply and have influenced commodity prices. The importance of exceptionally large, or rich, deposits has greatly increased in the age of globalization when a small number of international corporations dominate the metals market, based on few very large ore deposits, practically anywhere in the world. Search for giant orebodies thus drives the exploration industry: not only the in-house teams of large internationals, but also hundreds of junior companies hoping to sell their significant discoveries to the "big boys." Geological characteristics of giant metallic deposits and their setting and the politico-economic constraints of access to and exploitation in prospective areas have been a "hot topic" in the past fifteen years, but the knowledge generated and published has been one-sided, scattered and fragmented. This is the first comprehensive book on the subject that provides body of solid facts rather than rapidly changing theories, written by author of the Empirical Metallogeny book series and founder of the Data Metallogenica visual knowledge system on mineral deposits of the world, who has had an almost 40 years long international academic and industrial experience. The book will provide abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants," and some inspiration for commodity investors.

Underground Excavations in Rock deals with the geotechnical aspects of the design of underground openings for mining and civil engineering processes.
Constantly in the news and the subject of much public debate, fracking, as it is known for short, is one of the most promising yet controversial methods of extracting natural gas and oil. Today, 90 percent of natural gas wells use fracking. Though highly effective, the process-which fractures rock with pressurized fluid-has been criticized for polluting land, air, and water, and endangering human health. A timely addition to Oxford's What Everyone Needs to Know series, Hydrofracking tackles this contentious topic, exploring both sides of the debate and providing a clear guide to the science underlying the technique. In concise question-and-answer format, Alex Prud'homme cuts through the maze of opinions and rhetoric to uncover key points, from the economic and political benefits of fracking to the health dangers and negative effects on the environment. Prud'homme offers clear answers to a range of fundamental questions, including: What is fracking fluid? How does it impact water supplies? Who regulates the industry? How much recoverable natural gas exists in the U.S.? What new innovations are on the horizon? Supporters as diverse as President Obama and the conservative billionaire T. Boone Pickens have promoted natural gas as a clean, "21st-century" fuel that will reduce global warming, create jobs, and provide tax revenues, but concerns remain, with environmental activists like Bill McKibben and others leading protests to put an end to fracking as a means of obtaining alternative energy. Prud'homme considers ways to improve methods in the short-term, while also exploring the possibility of transitioning to more sustainable resources-wind, solar, tidal, and perhaps nuclear power-for the long term. Written for general readers, Hydrofracking clearly explains both the complex science of fracking and the equally complex political and economic issues that surround it, giving readers all the information they need to understand what will no doubt remain a contentious issue for years to come.
Natural gas is the world s cleanest fossil fuel; it generates less air pollution and releases less CO2 per unit of useful energy than liquid fuels or coals. With its vast supplies of conventional resources and nonconventional stores, the extension of long-distance gas pipelines and the recent expansion of liquefied natural gas trade, a truly global market has been created for this clean fuel. Natural Gas: Fuel for the 21st Century discusses the place and prospects of natural gas in modern high-energy societies. Vaclav Smil presents a systematic survey of the qualities, origins, extraction, processing and transportation of natural gas, followed by a detailed appraisal of its many preferred, traditional and potential uses, and the recent emergence of the fuel as a globally traded commodity. The unfolding diversification of sources, particularly hydraulic fracturing, and the role of natural gas in national and global energy transitions are described. The book concludes with a discussion on the advantages, risks, benefits and costs of natural gas as a leading, if not dominant, fuel of the 21st century. This interdisciplinary text will be of interest to a wide readership concerned with global energy affairs including professionals and academics in energy and environmental science, policy makers, consultants and advisors with an interest in the rapidly-changing global energy industry.

Originally published in 1911, this book contains a list of the specimens of stones in the collection of the Sedgwick Museum in Cambridge that are suitable for use in construction. Watson prefaces the catalogue with descriptive notes on the various types of stone, their natural location and genesis, in language that is accessible to non-geologists. This book will be of value to anyone with an interest in the history of the Sedgwick Museum or the history of science.
The book provides the first comprehensive and thematic treatment of micropalaeontology and its applications in petroleum exploration. The first part deals with pure micropalaeontology, and the second part with the principles and practices of applied micropalaeontology and sequence stratigraphy. Case histories of applications in a range of geographic, geologic, and stratigraphic settings are given.
This companion volume to the author's Geological Evolution of South East Asia (1989) is the first and only book to give an analysis of the oil, gas, and mineral deposits of Southeast Asia, including its economic geology. The stratigraphy, structure, hydrocarbon and coal deposits of the major Tertiary basins are described, and regional similarities and differences are analyzed. Among the areas featured are the copper and gold-silver deposits of the Philippines and Indonesia; the Sundaland peninsular core, considered the foremost source of tungsten and tin; and the declining tin mines of Malaysia and Thailand. This comprehensive survey will interest both the economic geologist and researcher of oil and mineral deposits.
This is the candid and often colourful account of the personal experiences of a resource analyst; experiences that led to major contributions in the modelling and forecasting of petroleum discovery rates and of potential oil and gas supply. The author's approach is largely nontechnical. He relates the difficulties encountered in integrating geoscience, economics, and statistics, and stresses the value of critically examining data before formulating theories or building formal models.
The coalbed methane (CBM) reserve in China ranks third in the world with a total resource of 36.8x1012 m3. Exploitation of CBM has an important practical significance to ensure the long-term rapid development of China natural gas industry. Therefore, in 2002, the Ministry of Science and Technology of China set up a national 973 program to study CBM system and resolve problems of CBM exploration and exploitation in China. All the main research results and new insights from the program are presented in this book. The book is divided into 11 chapters. The first chapter mainly introduces the present situation of CBM exploration and development in China and abroad. Chapters 2 through 9 illustrate the geological theory and prospect evaluation methods. Then chapters 10 and 11 discuss CBM recovery mechanisms and technology. The book systematically describes the origin, storage, accumulation and emission of CBM in China, and also proposes new methods and technologies on resource evaluation, prospect prediction, seismic interpretation and enhanced recovery. The book will appeal to geologists, lecturers and students who are involved in the CBM industry and connected with coal and conventional hydrocarbon resources research.
This well-illustrated book aims to enhance observations and understanding of structural features and proximity-indicator minerals, critical in exploration. The book provides a unique blending of different content on observational and critical aspects of data acquisition, geological, structural, tectonic set-up, mineral deposit types, geophysical framework, and proximity indicator minerals. Combining these topics led to a comprehensive understanding to facilitate mineral targeting and exploration in green- and brown-field terrains. Besides field photographs, the write-up is lavishly supplemented with relevant geological and geophysical maps, tables, and case stories in field geology, making it useful for a much larger section of the geoscientific community professional geologists and geophysicists, students, teachers, and also decision-makers in geo-surveys and exploration. |
