Assessing the date of the global oil peak: the need to use 2P reserves

Combining geological knowledge with proved plus probable ('2P') oil discovery data indicates that over 60 countries are now past their resource-limited peak of conventional oil production. The data show that the global peak of conventional oil production is close. Many analysts who rely only on proved ('1P') oil reserves data draw a very different conclusion. But proved oil reserves contain no information about the true size of discoveries, being variously under-reported, over-reported and not reported. Reliance on 1P data has led to a number of misconceptions, including the notion that past oil forecasts were incorrect, that oil reserves grow very significantly due to technology gain, and that the global supply of oil is ensured provided sufficient investment is forthcoming to 'turn resources into reserves'. These misconceptions have been widely held, including within academia, governments, some oil companies, and organisations such as the IEA. In addition to conventional oil, the world contains large quantities of non-conventional oil. Most current detailed models show that past the conventional oil peak the non-conventional oils are unlikely to come on-stream fast enough to offset conventional's decline. To determine the extent of future oil supply constraints calculations are required to determine fundamental rate limits for the production of non-conventional oils, as well as oil from gas, coal and biomass, and of oil substitution. Such assessments will need to examine technological readiness and lead-times, as well as rate constraints on investment, pollution, and net-energy return. (C) 2007 Elsevier Ltd. All rights reserved.

Rethinking "energy nationalism": a study of the relationship between nation states and companies in the oil industry

ABSTRACTThe term "energy nationalism" is frequently used by academic literature and media, but usually without adequate conceptual accuracy. Despite this, a set of papers deepens the discussion on the relationship between nation states and the energy industry, especially the oil sector. These papers allow identifying fundamental elements to understand the energy nationalism, either complementary or divergent between each other. Thus, this study aims at presenting an interpretation of the concept that fills the gaps left by the above mentioned literature based on a global analysis of the oil industry structure and its historical evolution since the mid-19thcentury.

Why do oil importers diversify their import sources politically? : evidence from U.S. firm-level data

International politics affects oil trade. But why? We construct a firm-level dataset for all U.S. oil-importing companies over 1986-2008 to examine what kinds of firms are more responsive to change in "political distance" between the U.S. and her trading partners, measured by divergence in their UN General Assembly voting patterns. Consistent with previous macro evidence, we first show that individual firms diversify their oil imports politically, even after controlling for unobserved firm heterogeneity. We conjecture that the political pattern of oil imports from these individual firms is driven by hold-up risks, because oil trade is often associated with backward vertical FDI. To test this hold-up risk hypothesis, we investigate heterogeneity in responses by matching transaction-level import data with firm-level worldwide reserves. Our results show that long-run oil import decisions are indeed more elastic for firms with oil reserves overseas than those without, although the reverse is true in the short run. We interpret this empirical regularity as that while firms trade in the spot market can adjust their imports immediately, vertically-integrated firms with investment overseas tend to commit to term contracts in the short run even though they are more responsive to changes in international politics in the long run.

Változik-e a kőolaj szerepe a világgazdaságban és Magyarországon? = The (un)changing role of oil in global economy and Hungary

A kőolaj (és a földgáz), a XX. században felfutott fosszilis energiahordozók történetileg a szenet váltották fel. Ma egyértelműen meghatározzák a világ energiafelhasználását. Miután fosszilisak, rövid távon nem újratermelhetőek, ezért felhasználásuk történetét végigkísérte a feltárt és feltárható készletek mennyiségének állandó újrabecslése is, és folyamatosan jelen van a végességükre vonatkozó apokaliptikus kép, amit az elmúlt 40 év rendkívül hektikus, sokszor kiugróan magas árai is alátámasztanak. Cikkünkben reális képet szeretnénk adni az olaj mennyiségi és árváltozásairól, és ezek lehetséges közgazdasági, társadalmi hatásairól. Miután a rendelkezésre álló hely kevés, csak a legfontosabb összefüggéseket emeljük ki, bizonyos adatokat is inkább illusztrációszerűen közlünk. Célunk nem mélyelemzés, hanem egy átfogó helyzetkép. Vázoljuk a kőolajjal kapcsolatos fontosabb történeti mozzanatokat, a kőolaj felhasználásának irányait Európában és Magyarországon, valamint a készletekkel kapcsolatos összefoglaló gondolatokat. _______________ The volatile oil prices of the past 40 years have always foreshadowed an apocalyptic vision of the exhaustion of global reserves. The paper reviews the important historical moments of the usage of oil, with a special focus on Europe and Hungary. It also details issues related to oil reserves. The main conclusions of the paper are the following: (1) fears of exhausting oil reserves have been rebutted several times; (2) high oil prices can be barriers to the development of the transportation sector, even if innovation is happening in the background; (3) the distribution of oil reserves carries huge political risks; and (4) it is unclear what will take the place of oil as the main source of energy.

The Current State of Argentina's Oil Industry

An oil wealthy country, Argentina has repeatedly tried and failed to capitalize on its potential. The unfortunate energy policies of subsequent Argentinean government and a lack of investment capital have been two of the main reasons that have significantly limited the production of export oil in the recent past. Yet, with recent discoveries and changes to the country’s hydrocarbon laws, there may be a new dawn for Argentina’s oil industry. Since 1999 when Argentina’s oil production peaked at approximately 800,000 barrels per day, there has been a 24 percent decrease in its oil output. The country’s oil reserves have also been in steady decline. Yet, the recently enacted reforms by Argentina’s government to incentivize foreign investment in the oil industry seem to be working, allowing investors to negotiate the terms of exploration directly with local governments. As a result, foreign investment is increasing, as well as new willingness to finance exploration of untapped reserves. Also, the discovery of shale oil in Argentina may provide the potential to become a key exporter in the region. Nonetheless, there are challenges that need to be overcome and it may be years before the various oil projects underway become profitable. The success of current oil projects, coupled with the potential of shale oil, new discoveries and the sustainability of the current energy policy reforms will likely determine if Argentina is finally able to fulfill its potential and exert itself as an oil exporter country in Latin America.

The importance of the industrialization of Brazilian shale when faced with the world energy scenario

This article discusses the importance of the industrialization of Brazilian shale based on factors such as: security of the national energy system security, global oil geopoliticsl, resources available, production costs, oil prices, environmental impacts and the national oil reserves. The study shows that the industrialization of shale always arises when issues such as peak oil or its geopolitics appear as factors that raise the price of oil to unrealistic levels. The article concludes that in the Brazilian case, shale oil may be classified as a strategic resource, economically viable, currently in development by the success of the retorting technology for extraction of shale oil and the price of crude oil. The article presents the conclusion that shale may be the driving factor for the formation of a technology park in Sao Mateus do Sul, due to the city`s economic dependence on Petrosix.

Valorização da Borra de Café: Otimização da Produção de Biodiesel por Catálise Enzimática

O decréscimo das reservas de petróleo e as consequências ambientais resultantes do recurso a combustíveis fósseis nos motores a diesel têm levado à procura de combustíveis alternativos. Esta pesquisa alicerçada nas fontes de energia renovável tornou-se essencial, face à crescente procura de energia e ao limitado fornecimento de combustíveis fósseis . Resíduos de óleo de cozinha, gordura animal, entre outros resíduos de origem biológica, tais como a borra de café, são exemplos de matérias-primas para a produção de biodiesel. A sua valorização tem interesse quer pela perspetiva ambiental, quer pela económica, pois aumenta não só a flexibilidade e diversificação das matérias-primas, mas também contribui para uma estabilidade de custos e alteração nas políticas agrícolas e de uso do solo. É neste contexto que se enquadra o biodiesel e a borra de café, pretendendo-se aqui efetuar o estudo da produção, à escala laboratorial, de biodiesel a partir da borra de café, por transesterificação enzimática, visando a procura das melhores condições reacionais. Iniciando-se com a caracterização da borra de café, foram avaliados antes e após a extração do óleo da borra de café, diversos parâmetros, de entre os quais se destacam: o teor de humidade (16,97% e 6,79%), teor de cinzas (1,91 e 1,57%), teor de azoto (1,71 e 2,30%), teor de proteínas (10,7 e 14,4%), teor de carbono (70,2 e 71,7%), teor de celulose bruta (14,77 e 18,48%), teor de lenhina (31,03% e 30,97%) e poder calorifico superior (19,5 MJ/kg e 19,9 MJ/kg). Sumariamente, constatou-se que os valores da maioria dos parâmetros não difere substancialmente dos valores encontrados na literatura, tendo sido evidenciado o potencial da utilização desta biomassa, como fonte calorifica para queima e geração de energia. Sendo a caracterização do óleo extraído da borra de café um dos objetivos antecedentes à produção do biodiesel, pretendeu-se avaliar os diferentes parâmetros mais significativos. No que diz respeito à caracterização do óleo extraído, distingue-se a sua viscosidade cinemática (38,04 mm2/s), densidade 0,9032 g/cm3, poder calorífico de 37,9 kcal/kg, índice de iodo igual a 63,0 gI2/ 100 g óleo, o teor de água do óleo foi de 0,15 %, o índice de acidez igual a 44,8 mg KOH/g óleo, ponto de inflamação superior a 120 ºC e teor em ácidos gordos de 82,8%. Inicialmente foram efetuados ensaios preliminares, a fim de selecionar a lipase (Lipase RMIM, TL 100L e CALB L) e álcool (metanol ou etanol puros) mais adequados à produção de biodiesel, pelo que o rendimento de 83,5% foi obtido através da transesterificação mediada pela lipase RMIM, utilizando como álcool o etanol. Sendo outro dos objetivos a otimização do processo de transesterificação enzimática, através de um desenho composto central a três variáveis (razão molar etanol: óleo, concentração de enzima e temperatura), recorrendo ao software JMP 8.0, determinou-se como melhores condições, uma razão molar etanol: óleo 5:1, adição de 4,5% (m/m) de enzima e uma temperatura de 45 ºC, que conduziram a um rendimento experimental equivalente a 96,7 % e teor de ésteres 87,6%. Nestas condições, o rendimento teórico foi de 99,98%. Procurou-se ainda estudar o efeito da adição de água ao etanol, isto é, o efeito da variação da concentração do etanol pela adição de água, para teores de etanol de 92%, 85% e 75%. Verificou-se que até 92% decorreu um aumento da transesterificação (97,2%) para um teor de ésteres de (92,2%), pelo que para teores superiores de água adicionada (75% e 85%) ocorreu um decréscimo no teor final em ésteres (77,2% e 89,9%) e no rendimento da reação (84,3% e 91,9%). Isto indica a ocorrência da reação de hidrólise em maior extensão, que leva ao desvio do equilíbrio no sentido contrário à reação de formação dos produtos, isto é, dos ésteres. Finalmente, relativamente aos custos associados ao processo de produção de biodiesel, foram estimados para o conjunto de 27 ensaios realizados neste trabalho, e que corresponderam a 767,4 g de biodiesel produzido, sendo o custo dos reagentes superior ao custo energético, de 156,16 € e 126,02 €, respetivamente. Naturalmente que não esperamos que, a nível industrial os custos sejam desta ordem de grandeza, tanto mais que há economia de escala e que as enzimas utilizadas no processo deveriam ser reutilizadas diversas vezes.

Development of Non-Petroleum Based Binders for Use in Flexible Pavements, TR-594, 2010

Most bituminous adhesives or binders that are used for pavement materials are derived primarily from fossil fuels. With petroleum oil reserves becoming depleted and the drive to establish a bio-based economy, there is a push to produce binders from alternative sources, particularly from biorenewable resources. However, until now, no research has studied the applicability of utilizing bio-oils as a bitumen replacement (100% replacement) in the pavement industry. The main objective of this research was to test various properties of bio-oils in order to determine the applicability of using bio-oils as binders in the pavement industry. The overall conclusions about the applicability of using bio-oils as bio-binders in the pavement industry can be summarized as follows: 1. Bio-oils cannot be used as bio-binders/pavement materials without any heat pre-treatment/upgrading procedure. 2. Current testing standards and specifications, especially Superpave procedures, should be modified to comply with the properties of bio-binders. 3. The temperature range of the viscous behavior for bio-oils may be lower than that of bitumen binders by about 30°–40° C. 4. The rheological properties of the unmodified bio-binders vary in comparison to bitumen binders, but the rheological properties of these modified bio-binders change significantly upon adding polymer modifiers. 5. The high-temperature performance grade for the developed bio-binders may not vary significantly from that of the bitumen binders, but the low-temperature performance grade may vary significantly

Spray Pyrolysed Tin Chalcogenide Thin Films: Optimization of optoelectronic properties of SnS for possible photovoltaic application as an absorber layer

In the early 19th century, industrial revolution was fuelled mainly by the development of machine based manufacturing and the increased use of coal. Later on, the focal point shifted to oil, thanks to the mass-production technology, ease of transport/storage and also the (less) environmental issues in comparison with the coal!! By the dawn of 21st century, due to the depletion of oil reserves and pollution resulting from heavy usage of oil the demand for clean energy was on the rising edge. This ever growing demand has propelled research on photovoltaics which has emerged successful and is currently being looked up to as the only solace for meeting our present day energy requirements. The proven PV technology on commercial scale is based on silicon but the recent boom in the demand for photovoltaic modules has in turn created a shortage in supply of silicon. Also the technology is still not accessible to common man. This has onset the research and development work on moderately efficient, eco-friendly and low cost photovoltaic devices (solar cells). Thin film photovoltaic modules have made a breakthrough entry in the PV market on these grounds. Thin films have the potential to revolutionize the present cost structure of solar cells by eliminating the use of the expensive silicon wafers that alone accounts for above 50% of total module manufacturing cost.Well developed thin film photovoltaic technologies are based on amorphous silicon, CdTe and CuInSe2. However the cell fabrication process using amorphous silicon requires handling of very toxic gases (like phosphene, silane and borane) and costly technologies for cell fabrication. In the case of other materials too, there are difficulties like maintaining stoichiometry (especially in large area films), alleged environmental hazards and high cost of indium. Hence there is an urgent need for the development of materials that are easy to prepare, eco-friendly and available in abundance. The work presented in this thesis is an attempt towards the development of a cost-effective, eco-friendly material for thin film solar cells using simple economically viable technique. Sn-based window and absorber layers deposited using Chemical Spray Pyrolysis (CSP) technique have been chosen for the purpose

La ausencia de Políticas Públicas sobre combustibles de origen biológico en Colombia y sus efectos sobre el medio ambiente

El cambio climático ha sido una de las mayores preocupaciones de los Estados en las últimas décadas como resultado de más de un siglo de explotación y empleo de un recurso natural no renovable que fue el motor del mundo en el siglo pasado y aún hoy mantiene a flote la economía de los países, el petróleo. En la actualidad, las reservas de petróleo han empezando a escasear. Por tanto, se han empezado a desarrollar estrategias para evitar una crisis energética global. La más importante la constituye la investigación y puesta en práctica de energías renovables y ambientalmente amigables como los biocombustibles. Los biocombustibles se perciben como una solución energética para el país. Sin embargo, la falta de articulación en la gestión de los actores de gobierno encargados de su puesta en práctica y de parámetros normativos fragmentarios al respecto, ocasiona una ausencia de políticas públicas de biocombustibles en Colombia; generando así que los compromisos ambientales y de reducción de emisiones de gas carbónico sean hoy, una meta por conquistar.

La tecnología del hidrógeno, una oportunidad estratégica para la perdurabilidad del sector energético en Colombia

El incremento de la actividad humana en el último siglo y el desarrollo de tecnologías ligadas con el petróleo como vector energético, han generado efectos medioambientales adversos que aunados con las limitadas reservas mundiales de crudo y su estrecha relación con el crecimiento económico mundial ha generado presiones economías, políticas y sociales en todos los países. Esta situación ha dinamizado la investigación y desarrollo de nuevas tecnologías basadas en el hidrogeno como un nuevo vector energético tecnológicamente compatible que permita la portabilidad de energía con el menor impacto ambiental y económico a la luz de la prospectiva de consumo y la perdurabilidad energética. Este trabajo identifica las experiencias más relevantes respecto a la tecnología del hidrogeno a nivel mundial con el fin de consolidar un plan estratégico para la incorporación del hidrógeno como vector energético al portafolio productivo colombiano mediante la aplicación de un modelo que permite el análisis del nivel de integración de los sectores educativo, empresarial y gubernamental, teniendo como base los resultados del análisis estructural y análisis de actores.

Implicaciones comerciales de la Diplomacia Petrolera China en el Amazonas ecuatoriano. 2007 - 2013

El presente Estudio de Caso tiene como objetivo analizar en qué medida las dinámicas comerciales de la Diplomacia Petrolera China han convertido a Ecuador en un socio estratégico para la RPCh. El petróleo como fuente de energía es primordial para llevar a cabo los procesos de industrialización y mantener el crecimiento económico del león Asiático. Por eso su búsqueda se ha convertido en un tema principal dentro de la agenda de política exterior. Ecuador, el tercer país de Suramérica con más reservas de petróleo, después de Venezuela y Brasil, se ha convertido en zona de influencia de la RPCh y a través de las empresas petroleras estatales se han firmado contratos por la venta de petróleo. A pesar de que las relaciones bilaterales son asimétricas, se buscar establecer si Ecuador es un socio estratégico en la región.

Extractivism, economic diversification and prospects for sustainable development in Ecuador

The objectives of this paper are first, evaluating economic, social and environmental effects on oil extraction in Ecuador during the last 41 years, and second, discussing prospects to achieving a sustainable and equitable development path in the future, in the context of declining oil reserves. The current government is pursuing an extractivist policy, based on expanding oil extraction in formerly unexploited fields -including those inside the Yasuni National Park- and starting largescale mining exploitation. Two future options will be evaluated, first, an expansion of extractive activities, and second an alternative based on conservation, with sustainable use of natural resources (e.g. ecotourism, agroforestry, bio-knowledge), without expansion of oil field expansion and mining.
