This book examines existing mineral fiscal policies covering income taxation, royalties, free carried and participative (community and government) interests and also highlights the impacts of these policies on the feasibility of mineral projects as well as on revenue and other benefits to the State. While publications already exist on the subject matter, they have invariably approached the topic primarily from a Government standpoint rather than the mining industry. This book aims to provide a balance in this debate by comparing the financial outcomes gained or foregone by both Government and industry under different policy regimes. The discussions are supported by quantitative examples to more clearly articulate the potential outcomes and better inform future fiscal policy decisions.

This book introduces the concepts and methods of spatial statistics to geologists and engineers working with oil and gas data, and covers all of the most commonly encountered geostatistical methods for estimation and simulation. Topics include calculation and modeling of semivariograms, linear methods of kriging, cokriging, nonlinear methods such as indicator kriging and disjunctive kriging, and conditional simulation, including sequential indicator simulation, sequential Gaussian simulation, and simulated annealing. Semivariogram models range from very simple to complex. All of the fundamental semivariogram models are illustrated, along with anisotropic models, hole effects, geometric and zonal models, and the mechanics of fitting models. For each geostatistical method treated in detail, the author introduces necessary theory and background, describes how the method works, the steps a user must go through, and problems a user might encounter. The emphasis throughout is on what the practitioner needs to know, and the results that can be expected. The book is replete with examples in two and three dimensions, using real-world data such as porosity and permeability, gas production, structural elevation of a reservoir, and seismic information. Geostatistics and Petroleum Geology will be an invaluable advanced-level text for students on petroleum engineering and geosciences courses, as well as an important reference for petroleum geologists and petroleum engineers in oil companies worldwide.

The application of surface geochemical methods to finding petroleum is based on the detection of hydrocarbons in the soil that have leaked from a petroleum reservoir at depth. While the "seal" over the deposit was once considered impermeable, surface geochemistry data now show that such leakage is a common occurrence. Despite its simplicity and low costs, surface geochemistry remains controversial because, until now, there was no objective and in-depth treatment of the various methods of surface geochemistry for oil exploration. Written by a successful oil finder, this practical guide: surveys a broad array of surface geochemistry techniques, from soil gases to microbiology, and provides clear strategies for applying them to the high-stakes art of petroleum exploration; offers numerous case studies, both successes and failures, to show the strengths and weaknesses of different approaches; examines statistical and spatial variation, surveys, and models in surface geochemistry, demonstrating how each analytical tool can be used to optimize accuracy; integrates surface geochemistry data interpretation with data from conventional methods of oil exploration, and considers the economics of surface geochemical approaches; and discusses key topics that have been neglected in the literature, such as grid design and the effects of soils. Geologists, geophysicists, geological engineers, and exploration managers involved in petroleum exploration will gain valuable insights from this volume. By presenting and evaluating each method of surface geochemistry in a neutral tone, this volume enables the reader to select and employ these methods with greater confidence.

This volume presents an exhaustive overview of major orebodies and mineral deposits of North Africa. It is intended both for academic researchers and especially for exploration geologists interested in mineral exploration in the northern part of the African continent. Recent changes in the mining laws of most countries in this region have encouraged international mining companies to invest in local mineral industries. Accordingly, this volume will be very useful for these professionals, as well as for researchers in the field of economic geology.

Permo-Triassic Salt Provinces of Europe, North Africa and the Atlantic Margins: Tectonics and Hydrocarbon Potential deals with the evolution and tectonic significance of the Triassic evaporite rocks in the Alpine orogenic system and the Neogene basins in the Iberian Peninsula, North Africa, and the western Mediterranean. As the nature of the Triassic evaporite sequences, the varied diapiric structures they feed, and the occurrence of hydrocarbons suggest that the Triassic evaporites represent an efficient system to trap hydrocarbons, this book explores the topic with a wide swath, also devoting content to a relatively unexplored topic, the mobilization and deformation of the Triassic salt in the western and northern Tethys (from Iberia and North Africa, Pyrenees and Alps, Adriatic and Ionian) during the subsequent Alpine orogenic processes. The book includes chapters updating varied topics, like the Permian and Triassic chronostratigraphic scales, palaeogeographic reconstructions of the western Tethys since the Late Permian, the petroleum systems associated with Permo-Triassic salt, allochthonous salt tectonics, and a latest revision of salt tectonic processes in the Permian Zechstein Basin, the Atlantic Margins (from Barents Sea, Scotia, Portugal, Morocco, and Mauritania), the Alpine folded belts in Europe, and the various Triassic salt provinces in North Africa. The book is the go-to guide for salt tectonic researchers and those working in the hydrocarbon exploration industry.

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.

How has exploration for minerals evolved in recent years? Is it as productive an activity as it once was? Why have changes occurred? Roderick G. Eggert explores these and other questions about the complex set of circumstances surrounding metallic mineral exploration. Originally published in 1987, Eggert documents trends in the level and the distribution of expenditures by mining companies for metallic mineral exploration and examines a number of factors that may be responsible for these trends. This significant study serves as a handy introduction to the subject for students interested in environmental studies, natural resources, and economics.

Education and Training for the Oil and Gas Industry: Localising Oil and Gas Operations, Volume Four in the Getenergy series will set out the case for localising the oil and gas operations within hydrocarbon-producing countries. The focus of this final Volume in the series will be to explore the value of engaging with local suppliers, local talent and other local stakeholders in the exploration and production of oil and gas resources. Specifically, we will set out an agenda around which operators and service companies can coalesce and that highlights the ways in which smart, targeted investments in education, training and local infrastructure can create a new way of doing business, particularly in developing or emerging energy economies. Getenergy Intelligence have developed a unique tool to evaluate the potential cost benefits of localisation for any given project. This volume lays out the rationale, methodology and processes we have developed to successfully map out localisation and implement strategic capacity development for oil and gas operations. The significant cost benefits of localisation have been recognised by a number of major oil and gas companies, but localisation is still an aspect of doing business that is poorly understood by much of the global industry. In the first section of this book, the authors provide the rationale for localisation and layout the core reasons for developing the tool. In the second section, the tool is described and the exact methodology is explained. In the final section the authors provide three case studies, demonstrating the tool in action and showing how we are able to measure the cost effectiveness and wider value of a coherent approach to localisation.

The Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book's empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors' field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages.

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment.The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

The book reveals the changing dynamics of the helium industry on both the supply-side and the demand-side. The helium industry has a long-term future and this important gas will have a role to play for many decades to come. Major new users of helium are expected to enter the market, especially in nuclear energy (both fission and fusion). Prices and volumes supplied and expected to rise and this will prompt greater efforts towards the development of new helium sources and helium conservation and recycling.

Published in 2002, the first edition of Geostatistical Reservoir Modeling brought the practice of petroleum geostatistics into a coherent framework, focusing on tools, techniques, examples, and guidance. It emphasized the interaction between geophysicists, geologists, and engineers, and was received well by professionals, academics, and both graduate and undergraduate students. In this revised second edition, Deutsch collaborates with co-author Michael Pyrcz to provide a full update on the latest tools, methods, practice, and research in the field of petroleum Geostatistics. Key geostatistical concepts such as integration of production data, scale-up, and cosimulation receive greater attention, and new topics like model checking, multiple point simulation, and production data integration are included in detail. Geostatistical methods are extensively illustrated through enhanced schematics, work flows and examples. A greater number of examples also are included, such as the integration of a single geostatistical study developed from data analysis and cleaning to post-processing, ranking and flow simulation. New methods, which have developed in the field since the publication of the first edition, are discussed, such as models for integration of diverse data sources, surface-based, advanced object-based, event-based and multiple point-based simulation, and spatial boot-strap.

This book presents operational modal analysis (OMA), employing a coherent and comprehensive Bayesian framework for modal identification and covering stochastic modeling, theoretical formulations, computational algorithms, and practical applications. Mathematical similarities and philosophical differences between Bayesian and classical statistical approaches to system identification are discussed, allowing their mathematical tools to be shared and their results correctly interpreted. The authors provide their data freely in the web at https://doi.org/10.7910/DVN/7EVTXG Many chapters can be used as lecture notes for the general topic they cover beyond the OMA context. After an introductory chapter (1), Chapters 2-7 present the general theory of stochastic modeling and analysis of ambient vibrations. Readers are first introduced to the spectral analysis of deterministic time series (2) and structural dynamics (3), which do not require the use of probability concepts. The concepts and techniques in these chapters are subsequently extended to a probabilistic context in Chapter 4 (on stochastic processes) and in Chapter 5 (on stochastic structural dynamics). In turn, Chapter 6 introduces the basics of ambient vibration instrumentation and data characteristics, while Chapter 7 discusses the analysis and simulation of OMA data, covering different types of data encountered in practice. Bayesian and classical statistical approaches to system identification are introduced in a general context in Chapters 8 and 9, respectively. Chapter 10 provides an overview of different Bayesian OMA formulations, followed by a general discussion of computational issues in Chapter 11. Efficient algorithms for different contexts are discussed in Chapters 12-14 (single mode, multi-mode, and multi-setup). Intended for readers with a minimal background in mathematics, Chapter 15 presents the 'uncertainty laws' in OMA, one of the latest advances that establish the achievable precision limit of OMA and provide a scientific basis for planning ambient vibration tests. Lastly Chapter 16 discusses the mathematical theory behind the results in Chapter 15, addressing the needs of researchers interested in learning the techniques for further development. Three appendix chapters round out the coverage. This book is primarily intended for graduate/senior undergraduate students and researchers, although practitioners will also find the book a useful reference guide. It covers materials from introductory to advanced level, which are classified accordingly to ensure easy access. Readers with an undergraduate-level background in probability and statistics will find the book an invaluable resource, regardless of whether they are Bayesian or non-Bayesian.

Tuzo is the never-before-told story of one of Canada's most influential scientists and the discovery of plate tectonics, a pivotal development that forever altered how we think of our planet. In 1961, a Canadian geologist named John "Jock" Tuzo Wilson (1908-1993) jettisoned decades of strongly held opposition to theories of moving continents and embraced the idea that they drift across the surface of the Earth. Tuzo tells the fascinating life story of Tuzo Wilson, from his early forays as a teenaged geological assistant working on the remote Canadian Shield in the 1920s to his experiences as a civilian-soldier in the Second World War to his ultimate role as the venerated father of plate tectonics. Illuminating how science is done, this book blends Tuzo's life story with the development of the theory of plate tectonics, showing along the way how scientific theories are debated, rejected, and accepted. Gorgeously illustrated, Tuzo will appeal to anyone interested in the natural world around them.

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.
