This paper presents the development of a prototype of a tubular linear induction motor applied to onshore oil exploitation, named MAT AE OS (which is the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation). The function of this motor is to directly drive the sucker-rod pump installed in the down hole of the oil well. Considering the drawbacks and operational costs of the conventional oil extraction method, which is based on the walking beam and rod, string system, the developed prototype is intended to become a feasible alternative from both technical and economic points of view. At the present time, the MAT AE OS prototype is installed in a test bench at the Applied Electromagnetism Laboratory at the Escola Politecnica da Universidade de Sao Paulo. The complete testing system is controlled and supervised by special software, enabling good flexibility in operation, data acquisition, and performance analysis. The test results indicate that the motor develops a constant lift force along the pumping cycle, as shown by the measured dynamometric charts. Also, the evaluated electromechanical performance seems to be superior to that obtained by the traditional method. The system utilizing the MAT AE OS prototype allows the complete elimination of the rod string sets required by the conventional equipment...

A exploração do petróleo no Brasil tem migrado para águas cada vez mais profundas; os campos de exploração estão cada vez mais distantes da costa e em regiões com condições meteoceanográficas cada vez mais severas. Isto, e o recente volume de novas descobertas e novos campos de exploração têm impulsionado as indústrias deste setor na busca por novas soluções para a exploração deste óleo. Uma destas soluções inovadoras são os FPWSO DP (Floating Production Storage Workover Offloading Dynamic Positioning Unit). Estas são unidades de produção, dotadas de sondas de perfuração e de sistema de posicionamento dinâmico. A utilização de unidades de posicionamento dinâmico para produção continua de campos de petróleo é algo novo no mundo. Por se tratar de plataformas que devem permanecer por vários meses produzindo de forma ininterrupta, o estudo de confiabilidade de seu sistema de posicionamento dinâmico é de vital importância. Este trabalho apresenta um estudo de confiabilidade para este tipo de embarcação. Serão avaliados todos os sistemas relacionados ao posicionamento dinâmico da unidade, entre eles, sistema de geração de energia, sistema de propulsão, controladores DP e sistemas de referência de posição. O trabalho apresenta também um estudo de confiabilidade do sistema de conexão e desconexão de emergência com o poço; sistema este que é a ultima salvaguarda caso haja uma perda de posição na unidade.; The exploitation of oil in Brazil has migrated to deeper and deeper waters; the exploration fields are increasingly distant from the coast and in regions with meteoceanográficas conditions increasingly severe.

Here we present a simple model of finite resource exploitation that is parameterized by initial cost ratio, a technologic and management index m accounting for the rise of the exploitation cost with decrease of resource amount, plus another index  accounting for the avidity of the market to the resource. The analysis showed that the model captures essential features of finite resource exploitation, namely those concerning to oil exploitation. Scenarios for future oil exploitation based on parameters estimated from historical data are analyzed and discussed, as well some other scenarios of generic resource exploitation.

Hydraulic fracturing emerges currently, all over the world, as one of the more strategic techniques used by companies in the oil exploitation sector. This technique is characterized by its high productivity and profit in relation to conventional methods of hydrocarbon exploitation. However, in many countries, as is the case of Brazil, there are several divergences considering the employment of this methodology. Many renowned researchers attest that there are several irreversible environmental impacts generated by the use of this methodology. Among the main environmental impacts are the risk of groundwater level contamination, the risk of surface subsidence, and the risk of the environment contamination with fluids used in the process of the oil and gas extraction.

This paper explores the effects of sugar and oil on identity formation or, more specifically, on the making of blackness and whiteness in the region surrounding Salvador, Bahia, where both commodities have had great impact, sugar from 1550 and oil from 1950, when drilling for oil began and a very large oil refinery was built. After comparing life under the economy of these two different commodities I connect them to the issue of a transnational black identity created across the Atlantic, drawing from a common past of slavery and a more recent past and present where racial hierarchies still penalize populations defined as black. This part of Bahia is emblematic for other regions of Brazil and other countries in which oil exploitation comes to substitute other mono-cultures (such as sugarcane, cocoa or small-scale fishing) while creating, often quite suddenly, a wholly different local economy, with new global connections, higher salaries, new conspicuous spending patterns, new values associated with certain forms of manual labour and technical skills, and an altogether new form of defining the nature of a "good job".

Deserts are among the most poorly monitored and understood biomes in the world, with evidence suggesting that their biodiversity is declining fast. Oil exploration and exploitation can constitute an important threat to fragmented and remnant desert biodiversity, yet little is known about where and how intensively such developments are taking place. This lack of information hinders local efforts to adequately buffer and protect desert wildlife against encroachment from anthropogenic activity. Here, we investigate the use of freely available satellite imagery for the detection of features associated with oil exploration in the African Sahelo-Saharan region. We demonstrate how texture analyses combined with Landsat data can be employed to detect ground-validated exploration sites in Algeria and Niger. Our results show that site detection via supervised image classification and prediction is generally accurate. One surprising outcome of our analyses is the relatively high level of site omission errors in Niger (43%), which appears to be due to non-detection of potentially small-scale, temporary exploration activity: we believe the repeated implementation of our framework could reduce the severity of potential methodological limitations. Overall...

Jatropha curcas is a plant of Latin American origin, now widespread through arid, and semiarid tropical regions of the world. It is a drought-resistant perennial, that grows on marginal soils, and, as a close relative to the castor plant, its oil has the same medical properties. In Mali, it is well-known and has long been recognized as a plant of many uses: Jatropha hedges not only protect gardens from hungry livestock, but reduces damage, and erosion from wind, and water. As of the 1930s, the oil potential as a fuel source was also recognized, currently used to substitute for the "gazoil" mixture used in the Indian type diesel engines, that drive grain mills, and water pumps in rural areas of Mali, while its high-quality oil extracted by engine-driven expellers, or by the sediment of the oil purification process, may be used for larger-scale soap making in rural areas, providing local women the chance to gain additional income, thus strengthening their economic position. The note examines all these possibilities...

"Through case studies of three emerging economies - Ecuador, Nigeria and Russia - this thesis analyses the factors present to a greater or lesser degree in emerging economies, such as severe foreign indebtedness and the absence of the rule of law, that undermine the effectiveness of the legal system in protecting indigenous peoples from oil exploitation. Having identified these factors, I propose that a dual approach to the protection of indigenous peoples' traditional lands and their environment be adopted, whereby international laws that set out the rights of indigenous peoples and place duties on states in this regard, are reinforced and translated into practice through the self-regulation of the international oil industry through a voluntary code of conduct for oil companies seeking to operate on indigenous peoples' traditional lands."; Thesis (Ph.D.)--University of Adelaide, Dept. of Law, 2001; Bibliography: leaves 651-699.; 2 v.

Despite massive oil rent incomes since the early 1970s, the economic performance of oil-exporting countries-with notable exceptions-is poor. While there is extensive literature on the management of oil resources, analysis of the underlying political determinants of this poor performance is more sparse. Drawing on concepts from the comparative institutionalist tradition in political science, the authors develop a generalized typology of political states that is used in analyzing the political economy of fiscal and economic management in oil-exporting countries with widely differing political systems. In assessing performance, the authors focus on issues of long-term savings, economic stabilization, and efficient use of oil rents. The comparisons of country experiences suggest that countries with strong, mature, democratic traditions have advantages in managing oil rents well because of their ability to reach consensus, their educated and informed electorates, and a high level of transparency that facilitates clear decisions on how to use rents over a long horizon. Yet even these systems...

The overall goal of the decommissioning of oil fields and mines initiative (the 'Initiative') is, in keeping with World Bank policy, to promote sustainable development by assisting governments to undertake and engage in earlier and more systematic, comprehensive, and responsive planning of the decommissioning and closure of mining and oil and gas production operations, as well as more effective implementation. The target audience for this Initiative are the governments of resource-rich countries, specifically the regulatory authorities, institutions, and ministries responsible for: administering mineral resource and oil and gas extraction contracts; issuing environmental permits for exploration, exploitation, and closure; and ensuring that legal, financial and technical measures are in place to address temporary shutdowns as well as complete closure and decommissioning at the end of the productive life of oil and gas and mining operations. This issues paper compiles findings of the first step of the Initiative. It is organized as: section one is an introduction. Section two presents the key trends and challenges faced by both the mining and oil and gas industries in decommissioning operations that have reached the end of their life cycle. Section three organizes findings and issues around what are believed to represent core components of a practical...

Globally, an increasing number of mines and hydrocarbon fields are nearing depletion, following decades of resource exploitation. These operations and the associated infrastructure will require complex and costly dismantling; technical and environmental restoration and rehabilitation measures; and socioeconomic investments to counteract retrenchment, post-closure economic downturns and other effects associated with the end of the project's productive life. The intent of this Toolkit is to serve as a resource to support the development of flexible but systematic regulatory approaches to key components of a sustainable decommissioning and closure planning and implementation process. This Toolkit is organized around what are believed to be core components of a practical approach that governments may adopt or adapt in the process of identifying and managing decommissioning and closure needs. The Toolkit structure is organized as: introduction and overview sets the stage on the purpose and objectives of the Toolkit...

Approximately two billion dollars a day of petroleum are traded worldwide, which makes petroleum the largest single item in the balance of payments and exchanges between nations. Petroleum represents the larger share in total energy use for most net exporters and net importers. While petroleum taxes are a major source of income for more than 90 countries in the world, poor countries net importers are more vulnerable to price increases than most industrialized economies. This paper has five chapters. Chapter one describes the key features of upstream, midstream, and downstream petroleum operations and how these may impact value creation and policy options. Chapter two draws on ample literature and discusses how changes in the geopolitical and global economic environment and in the host governments' political and economic priorities have affected the rationale for and behavior of National Oil Companies' (NOCs). Rather than providing an in-depth analysis of the philosophical reasons for creating aNOC, this chapter seeks to highlight the special nature of NOCs and how it may affect their existence...

Bolivia has the highest percentage of indigenous peoples in America and has recently attracted substantial investments in gas pipelines and in exploration work in new areas. the country also has one of the most dynamic indigenous peoples movement in the region. The joint UNDP/World Bank ESMAP program designed a pilot training program to instruct indigenous peoples on the impact of hydrocarbon activities. The pilot training program in Bolivia was sufficiently successful to warrant publication of this report. The report is organized as follows: After the Introduction, Chapter 2 describes the program's background. It addresses the development of the oil and gas industry in Bolivia, the specific demands of indigenous peoples in this respect, the progress made with the relevant legislation, and the circumstances under which this training program was designed. Chapter 3 describes the experience of program implementation, which was split into three phases: a preparatory phase, a development (training) phase, and a dissemination phase. Chapter 4 includes the lessons...

Countries heavily dependent on imported oil to power a significant portion of their electricity generation are especially vulnerable to high and volatile oil prices. In net oil-importing countries worldwide, high and volatile oil prices ripple through the power sector to numerous segments of the economy. As prices move up and down, so does the cost of electricity production, which has far-reaching effects on the economy, fiscal and trade balances, businesses, and household living standards. High and volatile oil prices affect economies at both a macro and micro level. The major direct effects at the macro level are a deteriorating trade balance, through a higher import bill, reflecting a worsening in terms of trade; and a weakening fiscal balance due to greater government transfers and subsidies to insulate movements in international energy markets. At the micro level, investment uncertainty results from the higher risk of engaging in new projects and associated development and sunk costs, which, in turn, affects policy decisions and economic growth. This study responds to the needs of policy makers and energy planners in oil-importing countries to better manage exposure to oil price risk. The study's objective is threefold. First...

Ghana's oil will start to flow in 2011, maybe even before, and most of its known reserves will be extracted in the immediate years after. The promise of oil generates expectations of all sorts, the more so as Ghana currently grapples with a macroeconomic crisis of significant proportions. This overview discusses the Ghana-specific nature of these challenges and explores possible options to address them. In doing so, it builds on seven thematic chapters which look at different aspects of the question: (1) oil facts, (2) political economy, (3) public financial management, (4) infrastructure, (5) private sector development, (6) agriculture, and (7) poverty. While the overview tries to bring together the findings of these different chapters, further details and discussions on each of these topics can be found in o f the chapters themselves. It concludes that while oil revenue will not be large enough to radically transform Ghana, it could, if improperly managed, impose enough stress on non-oil sectors to severely undermine Ghana's medium term development prospects. Hence the huge premium and responsibilities put on Ghana's successive authorities to wisely manage the oil wealth to promote the development of the non-oil sectors.

The macroeconomic impact of commodity windfalls has provided fertile ground for research since the 1970s. Particularly affected are developing countries that rely heavily on commodity exports. in the case of oil windfalls, cross-country experience is vast: Indonesia, Kazakhstan, Mexico, Nigeria, the Russian Federation, and Republica Bolivariana de Venezuela have all been buffered by such windfalls. The authors investigate Mexico's experience. They provide an overview of oil's impact on the Mexican economy and of the management of oil rents engineered by the government from the 1970s to date. A third of government revenues come from the hydrocarbon sector--especially oil exports. The reliance of public finance on a single commodity means that shocks threaten the economy's fiscal balance and stability. Policy options for protecting the economy from volatility in oil revenues without eliminating the benefits from rising prices include a stabilization fund and hedging strategies on international markets, which the authors discuss. The stabilization fund smoooths consumption and reduces the costs associated volatile spending. The fund and hedging strategies can complement each other--the fund working as the main recipient of revenues...
