Oil shales are broadly dermed as petroleum source rocks containing sufficiently high contents of organic matter (above ca 10-15 wt. %) to make utilisation a possibility. Like coal, the world's reserves of oil shales are vast being many times larger than those proven for crude oil. Indeed, some of the largest deposits occur in the USA and Europe where Estonia and Turkey have large reserves. The first recorded interest in oil shale retorting was an English patent in 1694 (Eele, Hancock and Porter, No. 330) which refers to distilling noyle from some kind of stone." The oil shale retorting industry dates back to the middle of the last century, notably Scotland, Estonia, France and Sweden in Europe. Indeed, my own Department at the University of Strathclyde has a historical link with James "Paraffin" Young, the founder of the Scottish oil shale industry who endowed a chair in Applied Chemistry. The growth of the oil industry saw the demise of the oil shale industry in most countries with the notable exception of Estonia, where kukersite has continued to be used for power generation and retorting. However, oil shale utilisation has attracted renewed attention since the early 1970s as a source of transport fuels and chemical feedstocks due to the the long term uncertainties over crude oil supplies.

Estimating abundance of wildlife is an essential component of a wildlife research program, and a prerequisite for sound management. With the exception of a few highly mathematical volumes, there are no books on the subject for use by students and field workers. Also, the various techniques for counting animals found in scientific journals are often not accessible to African managers. The unavailability of the diverse literature necessitated the production of a textbook or field manual that covers the ground. The book compiles the most relevant techniques for counting African mammals, illustrated with many examples from the field. It provides guidelines for selecting the appropriate methodology for a range of conditions commonly found in the field, in terms of different animal species, habitat types, and management objectives.

In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular.

According to the conventional wisdom, we live in a post-industrial information age. This book, however, paints a different picture: We live in the age of oil. Petroleum fuels and feedstocks are responsible for much of what we take for granted in modern society, from chemical products such as fertilizer and plastics, to the energy that moves people and goods in a global economy. Oil is a nearly perfect fuel: Energy dense, safe to store, easy to transport, and mostly environmentally benign. Most importantly, oil has been cheap and abundant during the past 150 years. In 1998, two respected geologists, Colin Campbell and Jean Laherrere, published a detailed article announcing that the "end of cheap oil" would happen before 2010, which meant that the world would face a peak, or at least a plateau, in global daily oil production in the first decade of the new millennium. Today, two billion people under the age of 14 have lived the majority of their lives past the point when this century-long growth in oil supplies came to an end, which also marks the end of the first half of the age of oil. This transition has ushered in a new reality of high oil prices, stagnating oil supplies, and sluggish economies. In this book, a leading authority on energy explores the contributions and continuing legacy of Colin Campbell and Jean Laherrere, the two geologists who modified the terms of the debate about oil. The book provides a unique perspective and state-of-the-art overview of today's energy reality and its enormous economic and social implications. - Covers a topic that eclipses climate change as the most important but least understood challenge for contemporary society - Explores the works of Colin Campbell and Jean Laherrere, the leading authorities in the field of Peak Oil, authors of "The End of Cheap Oil" (Scientific American, 1998), and founding members of the Association for the Study of Peak Oil & Gas - Addresses a broad audience of scientists, engineers, and economists in a format that is accessible to the general public - Provides a complete overview of the basic geological, chemical, physical, economic and historical concepts that every oil consumer should understand - Presents the latest information on oil production, reserves, discoveries, prices, and fields in easy-to-understand graphs and plots

Reservoirs generally consist of sandstones or carbonates exhibiting heterogeneities caused by a wide range of factors. Some of these formed depositionally (e.g. as channels, palaeosols, clay seams or salts), others may be diagenetic in origin (e.g. carbonate or silica cemented zones, authigenic clays, karstic surfaces). The severity with which diagenesis affects rock systems results from the interplay between the diagenetic process itself and the timescale over which it operated. The book provides a wide-ranging overview of diagenetic processes and responses in calcareous, argillaceous, arenaceous and carbon-rich (microbial and organic) sedimentary systems. It introduces diagenetic concepts, reviews existing knowledge, and shows how existing qualitative approaches might be developed in more quantitative ways. Several chapters consider mass balance calculations and the temporal and spatial aspects of diagenetic processes. It is unique, as a textbook, in providing such a breadth of diagenetic subject range and such depth of coverage in each topic. It provides a source reference for advanced students and professionals active in reservoir and aquifer studies.

In 1981 Chile's military government dictated a new Water Code that radically changed the country's previous water rights system by strengthening private property rights, favoring market incentives, and reducing state regulation. Against the Current: Privatization, Water Markets, and the State in Chile is the first empirical and interdisciplinary study of water markets in Chile, which is the leading international example of free market water policies. Against the Current: Privatization, Water Markets, and the State in Chile challenges the glowing reports given by neoliberals in Chile and the World Bank, showing that the results of this economic experiment have actually been rather mixed. Within the agricultural sector the Water Code has worked fairly well, although the market incentives to conserve water have been ineffective and water rights trading has been less active than expected. The Code's impact has been more negative at the level of river basins, where the institutional framework has revealed critical flaws in coordinating multiple water users and resolving conflicts. Against the Current: Privatization, Water Markets, and the State in Chile combines law, political economy, and geography to analyze the disadvantages, problems, and wider contexts of water markets. This book will appeal to everyone interested in property rights, market-friendly environmental policies, the political economy of sustainable development, and the intersection of economics with law and institutions.

One of the major challenges of sustainable development is the interdisciplinary nature of the issues involved. To this end, a team of conservation biologists, hunters, tourist operators, ranchers, wildlife and land managers, ecologists, veterinarians and economists was convened to discuss whether wildlife outside protected areas in Africa can be conserved in the face of agricultural expansion and human population growth. They reached the unequivocal - if controversial - conclusion that wildlife can be an economic asset, especially in the African savannas, if this wildlife can be sustainably utilized through safari hunting and tourism. Using the African savannas as an example, Wildlife Conservation by Sustainable Use shows that in many instances sustainable wildlife utilization comprises an even better form of land use than livestock keeping. Even when population pressure is high, as in agricultural areas or in humid zones, and wild animal species can pose a serious cost to agriculture, these costs are mainly caused by small species with a low potential for safari hunting. Although ranching has a very low rate of return and is hardly ever profitable, the biggest obstacle to the model of sustainable wildlife use outlined in Wildlife Conservation by Sustainable Use is from unfair competition from the agricultural sector, such as subsidies and lack of taxation, resulting in market distortion for wildlife utilization. This book thus gives valuable evidence for a different way of working, providing arguments for removing such distortions and thereby facilitating financially sound land use and making it a rationally sound choice to conserve wildlife outside protected areas. The expert team of authors, most of whom came together at a workshop to thrash out the ideas that were then developed into the various chapters, has written a superb account of recent research on this complex subject, resulting in a book that is a major contribution to our understanding of sustainable use of land. The important conclusion is that wildlife conservation can be possible for landholders and local communities if they have a financial interest in protecting wildlife on their lands.

oil is the lifeblood of the World's economy. It was a critical element in two World Wars and in the Cold War, and, as recent events in the Middle East confirm, people are willing to fight for it. The cheap energy it provides, especially for transport and agriculture, was one of the main factors that made possible the economic prosperity and growth that the World has enjoyed for the past fifty years and more. People rely on it everywhere, and in many forms, and they have become so accustomed to its ready availability that they take it for granted. To conceive of a world without traffic jams and airliners is unthinkable, and while not so obvious, oil lies behind every supermarket shelf, fuelling the tractor that ploughs the field and the delivery van that brings the consumer his food. Yet everyone knows that it is a finite and irreplaceable commodity, formed long ago in the geological past. What no one knows is just how finite it is. This book is an effort to try to answer that question : not in detail, but at least in orders of magnitude. More useful than the figures themselves is the discussion of the elements involved in addressing the subject. While it is impossible to predict the precise pattern of future production, which will be affected by many unforeseeable factors, one can at least begin to think in terms of resource constraint instead of an ever expanding supply of oil.

The first North Sea Oil and Gas Conference was held in Trondheim in 1985 as a part of the Norwegian Institute of Technology's 75th anniversary celebration. Favourable reactions from the delegates prompted the Organizing Committee to rerun the event in 1989. The response was again very encourag ing and led the Committee to conclude that the conference should be held on a regular basis so long as there is a demand for this type of gathering. The third conference in the series was held in 1992. The objectives of the conference series are fourfold: To bring together those who are engaged in various geoscientific and reservoir engineering aspects of North Sea oil and gas reservoirs in one forum; to demonstrate wherever possible the interdependence of the various disciplines and specializations; to promote innovative, synergetic approaches to research and development programmes aimed at North Sea conditions; and to reflect current trends in the reservoir sciences. The conference format has remained unchanged throughout the series. The present conference contained four field reviews by Amoco, Conoco, NAM Velsen, and Statoil, and four keynotes addresses by Professor R. Ewing, Dr. G. Geehan, Dr. D. Johnston, and Dr. F. Santarelli. Twenty-seven research papers were selected from the response to a Call for Papers in accordance with the aims of the conference and their technical contents.

Structural geologists are well aware of the fact that isotropic rocks are quite exceptional in nature. Whicheverorigin, sedimentary, metamorphicormagmatic, rocks are shaped with a plane of mineral flattening, the foliation in geologists' jargon, and with a line ofmineral elongation, the lineation. Just like a good quarryman, a trained structural geologistwill detectapreferredorientationin an apparently isotropic granite. Preferred mineral orientation and thus structural anisotropy are the rule in nature. Consideringthe largevariationsinelasticcoefficientsofrock-forming minerals, itcould be predicted that, in turn, seismic anisotropy should exist and be important, provided thatdomains withasimilarstructural signatureare largeenough to affectseismic waves. This is why, in 1982 at a conference held in Frankfurt, which was oneofthe fIrst meetings devoted to the subject of seismic anisotropy, I asked Don Anderson the question of why seismologists had not considered earlier in their models the obvious constraint of anisotropy. I still remember Don's answer: "Adolphe, we knew that our isotropic models were not very good but we had no other choice. It is simply that, so far, computerswere not largeenough tointegrate the anisotropy parameter." Changingisotropic glassesfor anisotropic ones permits us to obtain betterand more realistic seismic modelsofthe Earth's interior, but, maybe more importantly, it has, for a seismologist, the farreaching consequenceofsteppinginto the fIeld ofgeodynamics.

Oceanic basalts are the most abundant rock type found at the earth's surface, and as such they have been the subject of considerable research, particularly since the concept of sea-floor spreading became widely accepted. This book provides a review of these rocks, first dicussing how we sample the ocean floor and what we know about the structure of the oceanic crust, followed by an overview of the various regional settings (Pacific crust, Atlantic crust, marginal basins, seamounts and islands) and finally examines the main processes (and their interactions) which prevail during the generation and emplacement of oceanic basalt magmas. This is a volume for geologists, geochemists and geophysicists and a source of reference for advanced undergraduate students and postgraduates in these disciplines.

The former Soviet Union possessed some of the world's largest reserves of energy and mineral resources. With the dissolution of the country in 1991, the former Soviet republics are now exercising complete control over their mining industries. The new Commonwealth of Independent States (CIS) consists of several new nations, well-endowed in hydrocarbons, metals, and industrial materials; efforts are now underway to boost development activities and attract foreign investment. Commonwealth members today are implementing policies to regulate energy and mineral development and enhance economic growth. This book provides a comprehensive overview of the energy and minerals industries of the CIS and other former Soviet republics outside the Commonwealth. Prospects for international cooperation and trade in hydrocarbons, metals, and nonmetals are examined, as are opportunities for joint ventures and technology transfers in mining. Economic relations between the CIS and several Asian nations are also analyzed. Contributors to the book from throughout the Commonwealth, Asia, Europe, and North America have a wide variety of backgrounds in the energy and mineral fields, including government, academia, and industry.

Sedimentation and Tectonics in Rift Basins: Red Sea - Gulf of Aden presents new case studies and synthesises the results of recent research on the sedimentological evolution of the Red Sea - Gulf of Aden rift system. This rift basin is generally regarded as the best natural geological laboratory in the world in which to study the processes of rift formation. Uplift of the rift margins in an arid climate results in extensive three-dimensional exposures of pre- and syn-rift strata and associated structures. These serve as analogues for the understanding and hydrocarbon exploration of deeper buried rift-systems on continental margins such as the North Sea and the Atlantic margins. The Red Sea - Gulf of Aden rift is also exceptional in that its stratigraphy spans all stages from pre-rift environments, syn-rift continental to marine environments through the rift to drift transition to post-rift sea-floor spreading. The work is arranged in eight sections: following a review of the sedimentology and stratigraphy of rift basins, the magmatism and structural evolution of the Red Sea - Gulf of Aden rift is reviewed. Subsequently, new case studies are presented of the early rifting environment, syn-rift sedimentation, tectonics and diagenesis, evaporites and salt tectonics. Post-rift sediments of the axial trough are then discussed along with studies of reefs, coastal zone and shelf sediments, and the tectonic geomorphology of the rift margin escarpment. This work results from extensive new research in the rift basin largely carried out under collaborative research projects by European and Middle Eastern geologists. It will be an invaluable reference work for geoscientists in the hydrocarbon, groundwater and mineral extraction industries, as well as for researchers in university departments of earth sciences, mining and physical geography.

Taking Complexity Seriously applies the advanced policy analysis technique of triangulation to what is now the world's most complex public policy challenge: sustainable development. One central problem of public policy analysis has been to find new ways of analyzing issues of increasing complexity and uncertainty. Triangulation is perhaps the best example of these novel techniques, as it uses various methods, databases, theories, and approaches to converge on what to do about the complex issue in question. Taking Complexity Seriously uses four different theoretical approaches (Girardian economics, cultural theory, critical theory, and the local justice framework) to triangulation in order to converge on answers to four major policy questions: What is sustainable development? Why is it an issue? What needs to be done? What can actually be done? These four approaches are used to analyze the sustainable development controversy that recently arose in the pages of Science magazine and the journal Ecological Applications. These different approaches prove highly potent in defamiliarizing conventional wisdom about sustainable development. Ultimately the different approaches will converge on novel answers to the four questions. The practical implications of these conclusions are drawn out at the end of Taking Complexity Seriously in a detailed case study of ecosystem management.

Mineral deposits are non-renewable; they do not grow in the ground. Sustainable use of finite mineral wealth requires that revenues from mineral extraction be invested in renewable wealth, education and infrastructure, machines and other production equipment, or in financial assets. Different countries, states and provinces have done so with a varying degree of success. Investing for Sustainability: The Management of Mineral Wealth highlights mineral rents investment funds in Norway, Alaska and Alberta, all of which derive considerable revenues from the production of petroleum bound to diminish over time. The book examines the institutional and political framework in which these funds are embedded and how successfully they have been used for making non-renewable petroleum wealth permanent. Investing for Sustainability: The Management of Mineral Wealth begins with a discussion of the elusive concept of sustainability. New technology and substitution has made a resource like peat obsolete long before it became exhausted physically. Jevons' famous book "The Coal Question" is discussed at some length as a case of unwarranted concern about the depletion of resources. The book also highlights other cases which strike a less happy note. Nauru, one of the smallest sovereign states in the world, has for decades lived off phosphate resources that are now running out. Nauru attempted to make its phosphate wealth permanent through investment funds but failed. Despite its success with its Permanent Fund, less of the oil wealth of Alaska has been made permanent than would appear warranted, and the same is true of Alberta and Norway. Judging from the experiences of the three funds, and the current political debate in Norway, Investing for Sustainability: The Management of Mineral Wealth suggests that it is essential that the citizenry at large benefit directly from mineral rents investment funds if they are to succeed.

The reasons for writing this book are very simple. We use and teach com puter aided techniques of mathematical simulation and of pattern recogni tion. Life would be much simpler if we had a suitable text book with methods and computer programmes which we could keep referring to. Therefore, we have presented here material that is essential for mathematical modelling of some complex geological situations, with which earth scientists are often confronted. The reader is introduced not only to the essentials of computer modelling, data analysis and pattern recognition, but is also made familiar with the basic understanding with which they can plunge into when solving related and more complex problems. This book first makes a case for seismic stratigraphy and then for pattern recognition. Chapter 1 provides an extensive review of applications of pattern recognition methods in oil exploration. Simulation procedures are presented with examples that are fairly simple to understand and easy to use on the computer. Several geological situations can be formulated and simulated using the Monte Carlo method. The binary lithologic sequences, discussed in Chapter 2, consist of alternating layers of any two of sand, shale and coal."

"The thesis of Philipp Antrett is focused on reservoir properties, petrography, lithofacies and sedimentology, core analysis and nanoporosity studies. It will be of major interest for colleagues involved in the exploration and production of tight gas reservoirs in Northern Europe and elsewhere." - Francois Roure, August 2012 This thesis describes a multidisciplinary, multiscale approach to the analysis of tight gas reservoirs. It focused initially on the facies architecture of a Permian tight gas field in the Southern Permian Basin (SPB), East Frisia, northern Germany. To improve field development, 3D seismic data, wireline and core data were compared to a reservoir analogue in the Panamint Valley, California, United States. In addition to the large scale approach, a work flow that investigates microporosity by combining Scanning Electron Microscopy-Broad Ion Beam (SEM-BIB) and optical microscopy was developed. For a better understanding of the depositional environment and reservoir rock distribution in the SPB, a sedimentary facies analysis of four cores from the tight gas field in East Frisia was compared to a second study area in northern central Germany. This study demonstrates that tight gas exploration and production requires multidisciplinary, multiscale approaches beyond standard seismic interpretation work flows to better understand the temporal and spatial evolution of these complex reservoirs.

The motivation for "The Handbook of World Salt Resources" was the First Symposium on Salt, held in Cleveland in May, 1962, which was sponsored and organized by the relatively young and dynamic Northern Ohio Geological Society. The user of this valuable compilation owes a debt of gratitude to that Society, to the Diamond Alkali Company which donated countless hours of Mr. Lefond's time, and above all, to author Stanley Lefond."

This thesis deals with Rare Earth Elements (REE), especially with neodymium used in permanent magnets, from a very scientific basis by providing basic research data. Despite the fact that REE are newsworthy and very important elements for a considerable bandwidth of todays' technologies, accompanied by the monopolistic supply-situation and Chinese politics, there are inexplicable data discrepancies about REE which have been recognized frequently but usually have not been addressed accordingly. So this analysis started with the hypothesis that the four application areas, namely computer hard disk drives (HDD), mobile phones, wind turbines and e-mobility (automotive traction), account for about 80% of the global annual neodymium-demand. The research methodology was a laboratory analysis of the composition of used magnets for HDDs and mobile phones and a literature and official report analysis of wind turbine and automotive neodymium use. The result was amazing and the hypothesis had to be withdrawn as these four areas only account for about 20% of neodymium use. This result raises some questions concerning actual use and thus potential recycling options.

Traditional notions of security are premised on the primacy of state security. In relation to energy security, traditional policy thinking has focused on ensuring supply without much emphasis on socioeconomic and environmental impacts. Non-traditional security (NTS) scholars argue that threats to human security have become increasingly prominent since the end of the Cold War, and that it is thus critical to adopt a holistic and multidisciplinary approach in addressing rising energy needs. This volume represents the perspectives of scholars from across Asia, looking at diverse aspects of energy security through a non-traditional security lens. The issues covered include environmental and socioeconomic impacts, the role of the market, the role of civil society, energy sustainability and policy trends in the ASEAN region.
