Greene, David L [ORNL

2007-02-01

The global energy system faces sweeping changes in the next few decades, with potentially critical implications for the global economy and the global environment. It is important that global institutions have the tools necessary to predict, analyze and plan for such massive change. This report summarizes the proceedings of an international workshop concerning methods of forecasting, analyzing, and planning for global energy transitions and their economic and environmental consequences. A specific case, it focused on the transition from conventional to unconventional oil and other energy sources likely to result from a peak in non-OPEC and/or global production of conventional oil. Leading energy models from around the world in government, academia and the private sector met, reviewed the state-of-the-art of global energy modeling and evaluated its ability to analyze and predict large-scale energy transitions.

The relationship between global oil price shocks and China's output: A time-varying analysis

International Nuclear Information System (INIS)

Cross, Jamie; Nguyen, Bao H.

2017-01-01

We employ a class of time-varying Bayesian vector autoregressive (VAR) models on new standard dataset of China's GDP constructed by to examine the relationship between China's economic growth and global oil market fluctuations between 1992Q1 and 2015Q3. We find that: (1) the time varying parameter VAR with stochastic volatility provides a better fit as compared to it's constant counterparts; (2) the impacts of intertemporal global oil price shocks on China's output are often small and temporary in nature; (3) oil supply and specific oil demand shocks generally produce negative movements in China's GDP growth whilst oil demand shocks tend to have positive effects; (4) domestic output shocks have no significant impact on price or quantity movements within the global oil market. The results are generally robust to three commonly employed indicators of global economic activity: Kilian's global real economic activity index, the metal price index and the global industrial production index, and two alternative oil price metrics: the US refiners' acquisition cost for imported crude oil and the West Texas Intermediate price of crude oil. - Highlights: • A class of time-varying BVARs is used to examine the relationship between China's economic growth and global oil market fluctuations. • The impacts of intertemporal global oil price shocks on China's output are often small and temporary in nature. • Oil supply and specific oil demand shocks generally produce negative movements in China's GDP growth while oil demand shocks tend to have positive effects. • Domestic output shocks have no significant impact on price or quantity movements within the global oil market.

Measuring global oil trade dependencies: An application of the point-wise mutual information method

International Nuclear Information System (INIS)

Kharrazi, Ali; Fath, Brian D.

2016-01-01

Oil trade is one of the most vital networks in the global economy. In this paper, we analyze the 1998–2012 oil trade networks using the point-wise mutual information (PMI) method and determine the pairwise trade preferences and dependencies. Using examples of the USA's trade partners, this research demonstrates the usefulness of the PMI method as an additional methodological tool to evaluate the outcomes from countries' decisions to engage in preferred trading partners. A positive PMI value indicates trade preference where trade is larger than would be expected. For example, in 2012 the USA imported 2,548.7 kbpd despite an expected 358.5 kbpd of oil from Canada. Conversely, a negative PMI value indicates trade dis-preference where the amount of trade is smaller than what would be expected. For example, the 15-year average of annual PMI between Saudi Arabia and the U.S.A. is −0.130 and between Russia and the USA −1.596. We reflect the three primary reasons of discrepancies between actual and neutral model trade can be related to position, price, and politics. The PMI can quantify the political success or failure of trade preferences and can more accurately account temporal variation of interdependencies. - Highlights: • We analyzed global oil trade networks using the point-wise mutual information method. • We identified position, price, & politics as drivers of oil trade preference. • The PMI method is useful in research on complex trade networks and dependency theory. • A time-series analysis of PMI can track dependencies & evaluate policy decisions.

What drives the formation of global oil trade patterns?

International Nuclear Information System (INIS)

Zhang, Hai-Ying; Ji, Qiang; Fan, Ying

2015-01-01

In this paper, the spatial characteristics of current global oil trade patterns are investigated by proposing a new indicator Moran-F. Meanwhile, the factors that influence the formation of oil trade patterns are identified by constructing four different kinds of spatial econometric models. The findings indicate that most oil exporters have an obvious export focus in North America and a relatively balanced export in Europe and the Asia-Pacific region. Besides supply and demand factors, technological progress and energy efficiency have also significantly influenced the oil trade. Moreover, there is a spillover effect of trade flow among different regions, but its impact is weak. In addition, oil importers in the same region have the potential to cooperate due to their similar import sources. Finally, promotion of oil importers' R&D investments can effectively reduce the demand for global oil trade. - Highlights: • A new spatial association Moran-F indicator that applies to trade flows is proposed. • Driving factors affecting the formation of oil trade patterns are identified. • Oil-exporting countries implement various export strategies in different regions. • Supply, demand and technological factors contribute to the oil trade patterns. • Spillover effect of each factor affecting oil trade flows does exist but is limited

Global oil prices, macroeconomic fundamentals and China's commodity sector comovements

International Nuclear Information System (INIS)

Chen, Peng

2015-01-01

This paper investigates the common movements of commodity sectors in China as well as the economic underpinnings of the comovements. We employ a Bayesian dynamic latent factor model to disentangle the common and idiosyncratic sector-specific factors of the prices of a group of China's commodity sectors: petrochemicals, grains, energy, non-ferrous metals, oils & fats, and softs. The results indicate that the common factor accounts for a significant portion of the fluctuations of China's commodity sectors, providing evidence of the strong commodity sector comovements in China. We further use a VAR model to link the common movements across China's commodity sectors to the underlying determinants, including global oil price shocks and domestic macroeconomic fluctuations. We find that the global oil price shocks have strong effects on the common movements across commodity sectors in China in addition to its domestic macroeconomic fluctuations at long horizons. However, at short horizons, the common movements across commodity sectors in China respond more strongly to the global oil shocks than to its domestic macroeconomic fluctuations. - Highlights: • We examine the comovements of commodity prices at the industry level in China. • The common factor accounts for a significant portion of commodity sector fluctuations. • We investigate the joint impacts of global oil price shocks and domestic macro fluctuations on the comovements. • The global oil price shocks have persistent and strong effects on the comovements. • The impacts of domestic macro fluctuations on the comovements differ at short and long horizons.

Exploring the undulating plateau: the future of global oil supply.

Science.gov (United States)

Jackson, Peter M; Smith, Leta K

2014-01-13

In this paper, we analyse the factors that will influence long-term oil supply and describe the future form of the global oil supply profile as an 'undulating plateau' rather than an irreversible, short-term peak or an ever upward trend of increasing production. The ultimate transition from a world of relatively plentiful and cheap oil to one of tight supply and high cost will be slow and challenging. An understanding of the signposts for the future path of supply and the drivers of that profile will be critical to managing the transition. The ultimate form of the global supply curve may well be dictated by demand evolution rather than a limited resource endowment in the longer term. Several factors will probably control future global oil supply. We believe that the scale of global oil resource will not constitute a physical supply limit for at least the next two or three decades. However, all categories of oil resources are already more expensive to develop than in the past, requiring high oil prices to stimulate supply growth. Lower rates of oil demand growth relative to economic growth, combined with more challenging supply growth, will probably lead to an undulating plateau sometime after 2040, with demand from non-Organization for Economic Cooperation and Development states continuing to dominate. Upstream investment requirements and oil price volatility will increase towards and beyond the undulating production plateau. In this new world, high oil prices will induce demand destruction, fuel substitution and ever increasing energy efficiency. As we discuss below, the fundamental differences between the IHS Cambridge Energy Research Associates' (IHS CERA) view of the future of oil supply and many peak oil supply models are the timing of the onset of a dramatic slowdown in the rate of growth of supply and the existence or otherwise of a production plateau. We do not dispute that supply will plateau and eventually fall; the question is when, how and at what price

The Aqueduct Global Flood Analyzer

Iceland, Charles

2015-04-01

As population growth and economic growth take place, and as climate change accelerates, many regions across the globe are finding themselves increasingly vulnerable to flooding. A recent OECD study of the exposure of the world's large port cities to coastal flooding found that 40 million people were exposed to a 1 in 100 year coastal flood event in 2005, and the total value of exposed assets was about US 3,000 billion, or 5% of global GDP. By the 2070s, those numbers were estimated to increase to 150 million people and US 35,000 billion, or roughly 9% of projected global GDP. Impoverished people in developing countries are particularly at risk because they often live in flood-prone areas and lack the resources to respond. WRI and its Dutch partners - Deltares, IVM-VU University Amsterdam, Utrecht University, and PBL Netherlands Environmental Assessment Agency - are in the initial stages of developing a robust set of river flood and coastal storm surge risk measures that show the extent of flooding under a variety of scenarios (both current and future), together with the projected human and economic impacts of these flood scenarios. These flood risk data and information will be accessible via an online, easy-to-use Aqueduct Global Flood Analyzer. We will also investigate the viability, benefits, and costs of a wide array of flood risk reduction measures that could be implemented in a variety of geographic and socio-economic settings. Together, the activities we propose have the potential for saving hundreds of thousands of lives and strengthening the resiliency and security of many millions more, especially those who are most vulnerable. Mr. Iceland will present Version 1.0 of the Aqueduct Global Flood Analyzer and provide a preview of additional elements of the Analyzer to be released in the coming years.

On-line measurement of oil contaminants in water by filter-based infrared analyzers

International Nuclear Information System (INIS)

Niemelae, P.

1994-01-01

The properties of a dedicated infrared analyzer for on-line measurement of the oil content of water, the Oili analyzer, are evaluated theoretically and with laboratory measurements. The analyzer was originally developed for controlling the discharge of ballast and bilge water from oil tankers and more than 200 such instruments have now been supplied for that purpose, representing about 10 % of the total market. Some technical improvements are suggested, and the improved instrument is shown to be capable of measuring oil in water to an accuracy of +- 20 % down to a detection limit of +5-10 ppm in the presence of high concentrations of interfering components and under varying environmental conditions. This opens up new potential applications for the instrument, e.g. the monitoring of water discharges from oil and gas production platforms. The infrared analyzer responds only to the dispersed oil fraction, and if the dissolved fraction is of interest as well, the instrument must be equipped with a UV option, as suggested here

Globalization and the uneven application of international regulatory standard : the case of oil exploration in Nigeria

Energy Technology Data Exchange (ETDEWEB)

Adalikwu, J.

2008-07-01

This study was conducted to increase the awareness of the current economic situation that exists in the Niger Delta, a region that has been devastated by the activities of oil multinational corporations (MNCs). In particular, the study linked the Obelle and Obagi communities to the political economy of global capital which creates inequalities that divide societies into hierarchies of the rich and poor. The strategies adopted by the people to improve the negative consequences of oil exploration in the communities were also examined. The researcher postulated that there is a relationship between the uneven application of international and national regulations in oil production by MNCs and environmental degradation. A critical ethnographic paradigm was used to explore and explain the processes of globalization that affect the people's lives and means of livelihood. Data were collected and analyzed using both qualitative and quantitative methods. Data was then analyzed using several methods, such as statistics based on cross-tabulation, analysis of themes that emerged from interviews, and Atlas.ti 5.0 qualitative analysis computer programme to show the relationship between variables that emerged from the study. The study revealed that resource exploitation by oil MNCs in Obagi/Obelle communities of the Nigeria Delta, together with the Nigerian government, has resulted in economic expropriation, political disenfranchisement, social instability and environmental damage.

Does oil move equity prices? A global view

International Nuclear Information System (INIS)

Nandha, Mohan; Faff, Robert

2008-01-01

Many studies indicate that oil price shocks have an adverse effect on real output and, hence, an adverse effect on corporate profits where oil is used as a key input. The present study examines whether and to what extent the adverse effect of oil price shocks impacts stock market returns. To this end we, analyse 35 DataStream global industry indices for the period from April 1983 to September 2005. Our findings indicate that oil price rises have a negative impact on equity returns for all sectors except mining, and oil and gas industries. Generally, these results are consistent with economic theory and evidence provided by previous empirical studies. Little evidence of any asymmetry is detected in the oil price sensitivities. In light of our findings, we recommend that international portfolio investors consider hedging oil price risk. (author)

Global oil outlook: return to the absence of surplus and its implications

International Nuclear Information System (INIS)

Salameh, Mamdouh G.

2000-01-01

As we approach the end of the 20th century, the global oil picture starts to look more like the early 1970s, which set the scene for the first oil crisis in 1973. The 'security margin' -- the gap between demand and production capacity, has been shrinking since the early 1990s. In 1985 OPEC was producing at only 55% of capacity. By 1997 capacity utilisation had risen to 95% and, barring the full re-entry of Iraq into the oil market, capacity utilisation in 1998 is projected to rise to 96% with a growth of more than 1.6 million barrels a day (mbd) in global demand. No wonder, then, that the 'capacity question' has been termed 'oil's perennial problem'. The dilemma confronting producers is either they face the danger of over investing if demand grows slowly or not at all, or they run the risk of investing too little, too late. Yet, without outright investment, the capacity constraint may start to bite at some point in the near future. This paper will endeavour to analyse the origins of the shrinking 'security margin' and its impact on the global oil supplies, the price of oil and the global economy. It will argue that under such conditions, one has to seriously consider the possibility of a third oil crisis capable of again disrupting the global economy, triggered again by political upheaval in the Middle East.

Intrastate conflict in oil producing states: A threat to global oil supply?

International Nuclear Information System (INIS)

Toft, Peter

2011-01-01

In this paper I investigate how often and how much outbreaks of intrastate conflict in oil producing states translates into oil supply shortfalls. The Libyan conflict that broke out in February 2011 highlighted the fear that intrastate conflict in oil producing states may imply shortfalls and ensuing volatile global oil prices. I argue, however, that it is far from certain that shortfalls following conflict outbreak will occur, since both sides in a conflict face incentives simultaneously to protect and maintain oil installations and to strike and destroy these. Based on a quantitative analysis of 39 intrastate wars in oil producing countries (1965-2007) I conclude that outbreak of conflict does not translate into production decline with any certainty. In fact, likelihoods are less than 50% for reductions to occur. In many cases growing production actually followed conflict outbreak. I conclude by investigating four characteristics of intrastate conflict that may explain when oil production is at risk during conflict: (1) proximity of oil producing fields to key battle zones, (2) duration of conflict, (3) separatism and the location of oil in separatist territory, and (4) the relative size of oil production. While the first three factors did not prove important, oil producer size could be significant. But further research is needed to establish this with greater certainty. - Highlights: → Oil shortfall during intrastate conflict is not a given. → Statistical analysis of 39 intrastate conflicts in oil producing countries since 1965. → Examination of four characteristics of intrastate conflict in oil producing countries. → Marginal significance related to large producers and production shortfall.

Kolk, A.; Levy, D.

2003-01-01

This chapter analyzes the strategic responses by U.S. and European multinational enterprises (MNEs) in the oil and automobile industries to the global climate change issue. We examine and attempt to explain the differences across regions, across industries, and the changes over time. Traditional economic drivers of strategy do not provide a satisfactory account for these differences, and the chapter focuses instead on the conflicting institutional pressures on MNEs and the implications for their climate strategy. The home-country institutional context and individual corporate histories can create divergent pressures on strategy for MNEs based in different countries. At the same time, the location of MNEs in global industries and their participation in 'global issues arenas' such as climate change generate institutional forces for strategic convergence. It appears that local context influenced initial corporate reactions, but that convergent pressures predominate as the issue matures

Species-specific vulnerability of Arctic copepods to oil contamination and global warming

DEFF Research Database (Denmark)

Dinh, Khuong Van; Nielsen, Torkel Gissel

Arctic ecosystems are predicted to have more severe effects from global warming as during the last decades the temperatures have increased in this region at a rate of 2-4 times higher than the global average. In addition, oil exploitation and shipping activities in the Arctic are predicted...... to increase under global warming as the result of the retreat of sea ice, posing the risk of oil contamination. It is poorly known how cold adapted copepods in the Arctic deal with the combined effects of global warming and oil exposure. To address this, we exposed females of two copepods species Calanus...... of temperatures. Notably, exposure to high pyrene resulted in ca. 70% of mortality in C. finmarchicus, the species with North Atlantic Origin, that was two times higher than the mortality observed for C. glacialis, the true Arctic species. These results suggest that extreme temperature under global warming...

Dating breaks for global crude oil prices and their volatility : a possible price band for global crude prices

International Nuclear Information System (INIS)

Liao, H.C.; Suen, Y.B.

2006-01-01

Global oil prices are among the most visible of all historical commodity records. This paper presented and applied the multiple structural change method developed by Baie and Perron (BP) to investigate daily West Texas Intermediate (WTI) spot prices from January 2, 1986 to December 30, 2004 as collected by the United States Department of Energy. In particular, the BP statistical method was used to estimate the number and location of structural breaks in global oil price series and their volatility. The objective was to precisely determine the exact structural break in the global oil market. The breaks for both the price of oil and its volatility were successfully located and dated. It was shown that the break for the structural change in oil prices occurred on November 12, 1999, where the average oil price was U$19.02 per barrel previously, and U$30.90 afterwards. Two breaks for oil price volatility were also found, the first in March 1991 and the other in December 1995. The volatility was measured in 3 regimes by dividing these 2 breaks. It was suggested that since oil prices increased more rapidly during the second half of 2004 and 2005, it is possible that another structural break may be found during this period. However, it wa cautioned that it is difficult to find another significant break until more data becomes available, particularly for periods characterized by a rapid increase in price. 24 refs., 5 tabs., 2 figs

The transformation of the global oil industry and its impact on international relations

International Nuclear Information System (INIS)

Appleyard, J.

1994-01-01

The transformations of ownership and control in the global oil industry since the first oil shock of 1974 are discussed and the impact of that change on several interconnected issues is explored. It is argued that structural changes in the industry affect interstate relations in ways that are of central concern to the discipline of international relations. Any likely future oil industry scenario will have considerable political and economic repercussions for both producer and consumer states, with a concommitant impact on the relations between those states more generally. There is a danger that interstate conflicts among oil producers will increase with perodic changes in the global supply and demand conditions for oil. Ways are suggested for international relations studies to take into account the change in the global oil industry and its impact on the distribution of power and on international order and justice. It is contended that a growing number of states must be considered as behaving much like firms in a competitive market, and the new international oil order both constrains and provides opportunities for those firm-like states. 20 refs

Oil price, biofuels and food supply

International Nuclear Information System (INIS)

Timilsina, Govinda R.; Mevel, Simon; Shrestha, Ashish

2011-01-01

The price of oil could play a significant role in influencing the expansion of biofuels, but this issue has yet to be fully investigated in the literature. Using a global computable general equilibrium (CGE) model, this study analyzes the impact of oil price on biofuel expansion, and subsequently, on food supply. The study shows that a 65% increase in oil price in 2020 from the 2009 level would increase the global biofuel penetration to 5.4% in 2020 from 2.4% in 2009. If oil prices rise 150% from their 2009 levels by 2020, the resulting penetration of biofuels would be 9%, which is higher than that would be caused by current mandates and targets introduced in more than forty countries around the world. The study also shows that aggregate agricultural output drops due to an oil price increase, but the drop is small in major biofuel producing countries as the expansion of biofuels would partially offset the negative impacts of the oil price increase on agricultural outputs. An increase in oil price would reduce global food supply through direct impacts as well as through the diversion of food commodities and cropland towards the production of biofuels. - Highlights: ► A global CGE model to analyze impacts of oil price on biofuels and food supply. ► Global biofuel penetration increases from 2.4% (2009) to 5.4% (2020) in baseline. ► A 150% rise of oil price boosts biofuels more than current mandates and targets do. ► Biofuels partially offset drops in agricultural outputs caused by oil price rise. ► Biofuels as well as oil price rise negatively affect global food supply.

Full Text Available Water diffusion characteristics of mineral and vegetable oil-paper insulation systems are important for insulation condition evaluation of oil-filled transformers. In this paper, we describe a novel application method of in situ attenuated total reflection Fourier transform infrared (ATR-FTIR approach for analyzing the diffusion process of water molecules in oil-immersed insulating paper. Two-dimensional correlation was used to analyze the 3700 cm-1 to 3000 cm- 1 hydroxyl peak. The observed results indicated that water molecules form two types of hydroxyl (OH with oil-impregnated paper in the diffusion process are weak and strong hydrogen bonds, respectively. 2D infrared correlation analysis revealed that three OH stretching vibration spectra absorption peaks was existed in hygroscopic vegetable oil-immersed insulating paper. And there are four OH stretching vibration spectra absorption peaks in mineral oil-immersed insulation paper. Furthermore, mineral oil-impregnated paper and vegetable oil-impregnated paper diffusion coefficients were obtained by nonlinear fitting.

Full Text Available The demand for asphalt and road oil heavily leverages local supply because the product is a hot binder of aggregates that form the final mix needed to pave roads. This paper discusses the supply chain characteristics of crude oil feedstock by considering the overall logistics of sourcing heavy crude oil domestically, or importing it from international trading partners. Heavy crude oil is a source of asphalt and road oil production. The study examines critical global and domestic logistics factors such as customs, regulations, security, environmental compliance, and natural events that will affect costs, schedules, and risks. The study provides a framework for decision-making in sourcing the feedstock. The study helps global logisticians and transportation managers improve strategic design and planning towards efficient sourcing.

Impact Of The Oil Trade On The Global Economy And The Role Of Giant Fields In Predicting Supply

Energy Technology Data Exchange (ETDEWEB)

Kelley, Wayne; Bishop, Richard

2010-09-15

Confusion about global oil supply ('peak oil') is a distraction from the economic issue of massive wealth transfer associated with oil trading and its potential to destabilize the world economy. Without an accurate forecast of oil volumes (resources, reserves and supply), timing and cost, there is no reliable way to model the consequences of the oil trade on the global economy. This paper illustrates why it is imperative to improve our understanding of the oil trade on the global economy and proposes a method of forecasting oil supply for input into a credible global economic model.

Global economic activity and crude oil prices. A cointegration analysis

He, Yanan; Wang, Shouyang; Lai, Kin Keung

2010-01-01

This paper empirically investigates the cointegrating relationship between crude oil prices and global economic activity. The Kilian economic index is used as an indicator of global economic activity. Based on a supply-demand framework and the cointegration theory, we find that real futures prices of crude oil are cointegrated with the Kilian economic index and a trade weighted US dollar index, and crude oil prices are influenced significantly by fluctuations in the Kilian economic index through both long-run equilibrium conditions and short-run impacts. We also develop an empirically stable, data-coherent and single-equation error-correction model (ECM) which has sensible economic properties. Empirical results based on the ECM show that the adjustment implied by a permanent change in the Kilian economic index is a relatively drawn-out process. (author)

Fluctuations in the oil global market has been a critical topic for the world economy so that analyzing and forecasting the conventional oil production rate has been examined by many researchers thoroughly. However, the dynamics of the market has not been studied systematically with regard to the new emerging competitors, namely unconventional oil. In this paper, the future trend of conventional and unconventional oil production and capacity expansion rates are analyzed using system dynamics approach. To do so, a supply-side modeling approach is utilized while main effective loops are modeled mathematically as follows: technological learning and progress, long and short-term profitability of oil capacity expansion and production, and oil proved reserve limitations. The proposed model is used to analyze conventional and unconventional oil production shares, up to 2025, under different oil price scenarios. The results show that conventional oil production rate ranges from 79.995 to 87.044 MB/day, which is 75–80 percent of total oil production rate, while unconventional oil production rate ranges from 19.615 to 28.584 MB/day. Simulation results reveal that unconventional oil can gain a considerable market share in the short run, although conventional oil will remain as the major source for the market in the long run. - Highlights: • Variables and loops affecting oil production are formulated mathematically. • Shares of conventional and unconventional oil in the global oil market is analyzed. • Oil production rate under different oil price scenarios up to 2025 is simulated. • Unconventional oil would obtain a considerable share in market in the short-term. • A late peak for the conventional oil resources would occur.

After conventional waterflooding processes the residual oil in the reservoir remains as a discontinuous phase in the form of oil drops trapped by capillary forces and is likely to be around 70% of the original oil in place (OOIP). The EOR method so-called Alkaline-Surfactant-Polymer (ASP) flooding has been proved to be effective in reducing the oil residual saturation in laboratory experiments and field projects through reduction of interfacial tension and mobility ratio between oil and water phases. A critical step for the optimal design and control of ASP recovery processes is to find the relative contributions of design variables such as, slug size and chemical concentrations, in the variability of given performance measures (e.g., net present value, cumulative oil recovery), considering a heterogeneous and multiphase petroleum reservoir (sensitivity analysis). Previously reported works using reservoir numerical simulation have been limited to local sensitivity analyses because a global sensitivity analysis may require hundreds or even thousands of computationally expensive evaluations (field scale numerical simulations). To overcome this issue, a surrogate-based approach is suggested. Surrogate-based analysis/optimization makes reference to the idea of constructing an alternative fast model (surrogate) from numerical simulation data and using it for analysis/optimization purposes. This paper presents an efficient global sensitivity approach based on Sobol's method and multiple surrogates (i.e., Polynomial Regression, Kriging, Radial Base Functions and a Weighed Adaptive Model), with the multiple surrogates used to address the uncertainty in the analysis derived from plausible alternative surrogate-modeling schemes. The proposed approach was evaluated in the context of the global sensitivity analysis of a field scale Alkali-Surfactant-Polymer flooding process. The design variables and the performance measure in the ASP process were selected as slug size

One of the main elements of economic sanctions against Iran due to its nuclear and military programs is crude oil exportation restrictions in addition to investment in Iranian energy related projects. Senders of such sanction are interested in understanding the impacts of such embargos on international oil prices. We apply unrestricted vector autoregressive (VAR) model, using impulse response functions (IRF) and variance decomposition analysis (VDA) tools with annual data from 1965 to 2012 to analyze the dynamic response of international oil prices to Iranian oil export sanction. Controlling for the supply of non-Iranian oil, the world GDP per capita, and post-Islamic revolution exogenous dummy variables, we show that international oil prices respond negatively and statistically significant to increasing shock in absolute negative changes of the Iranian oil exports – our proxy of Iran oil sanctions – following the first 2 years after shock. The main reason is the positive response of the non-Iranian oil supply to negative shocks in Iranian oil exports, filling the missing supply of Iranian oil in international markets. - Highlights: • We analyze the interconnections between Iranian oil supply and global oil prices. • We use VAR modeling and annual data from 1965 to 2012 for the case of Iran. • There are no inflationary effects of Iranian oil sanction on world oil prices. • Non-Iranian oil supply offsets the missing Iranian oil in the market

The authors describe the equipment type MFS-7 which is intended for analyzing used oils for the wear products of motors. The difference between type MFS-7 and its predecessors lies in the application of computer techniques to control the equipment and process the output data; and in the design of the sample container, which allows for two methods of introducing the sample into the discharge. The photoelectric equipment consists of an excitation spectrum source IVS-28, having an ac arc mode and 1.v. spark, a polychoromator, a special sample holder for analyzing liquid samples, an electronic recording apparatus with digital voltmeter type ERU-18 and control computer system Spectr 2.2 based on a minicomputer with its own printer. The type MFS-7 equipment has been tested and put into mass production

Hydraulic Fracturing and Microseismicity: Global Perspective in Oil Exploration

Directory of Open Access Journals (Sweden)

Full Text Available Induced microseismicity is a common phenomenon in oil and gas reservoirs due to changes in internal stress accompanied by hydraulic fracturing and oil-gas extraction. These microseismicity can be monitored to understand the direction and type of hydraulic fracturing and pre-existing faults by precise hypocenter location and focal mechanism studies. Normal as well as strike-slip faulting earthquakes occur due to opening up of new cracks/fractures, and thrust/reverse faulting earthquakes due to compaction or closing of existing fractures. Further, frequency-magnitude relation (b-value and fractal dimension (D-value of the spatial and temporal clusterization of induced microseismicity may be much useful to characterize the fractures / existing faults and the stress regimes. Seismic tomography, on the other hand, can image the heterogeneous velocity structures / perturbations in the reservoir due to fractures and oil-gas-water contents. A few global case studies are illustrated to understand these processes and to draw attention towards importance of these studies in oil industries.

Full Text Available This study focuses on global integration, non-oil export and economic growth in Nigeria. The direct and interaction effect of the both openness variables and non-oil export on economic growth in Nigeria is investigated using quarterly data from 1986-2014. For analysis, it uses one measures of financial openness: de facto (total capital flow variables following Aizenman and Noy (2009.and a measure of trade openness adopted by Okoh (2004. The study applies the Autoregressive Distributed Lag Model (ARDL. The results show positive impact of non-oil export on economic growth in Nigeria both in the short run and in the long run, negative effect of trade and financial openness on economic growth however, the result recorded a negative effect of the interaction of trade openness and non-oil export on economic growth and a positive effect of the interaction of financial openness and non-oil export on economic growth. Thus, the study recommends among others that government should get the fundamentals right in the economy first that will boost non-oil sector before opening the economy for trade.

Transnational anew, competitive at last: the oil market in the globalization era

International political economy can be conceived as the study of the interaction between the confrontation of state sovereignties, whose regulation is primarily a question of power and secondarily of norms and institutional procedures and global economic activity (production and exchanges), which is a process of strategic interaction. The problem consists then in understanding how these two components are linked, influence over each other, support or conflict with each other in the global oil system. To consider oil in terms of International Political Economy (IPE), is thus to see it simultaneously as a potential object of inter-state confrontation and of economic competition. (A.L.B.)

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

Bentley, R.W.; Mannan, S.A.; Wheeler, S.J.

2007-01-01

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

Crude oil price volatility has been analyzed extensively for organized spot, forward and futures markets for well over a decade, and is crucial for forecasting volatility and Value-at-Risk (VaR). There are four major benchmarks in the international oil market, namely West Texas Intermediate (USA), Brent (North Sea), Dubai/Oman (Middle East), and Tapis (Asia-Pacific), which are likely to be highly correlated. This paper analyses the volatility spillover and asymmetric effects across and within the four markets, using three multivariate GARCH models, namely the constant conditional correlation (CCC), vector ARMA-GARCH (VARMA-GARCH) and vector ARMA-asymmetric GARCH (VARMA-AGARCH) models. A rolling window approach is used to forecast the 1-day ahead conditional correlations. The paper presents evidence of volatility spillovers and asymmetric effects on the conditional variances for most pairs of series. In addition, the forecast conditional correlations between pairs of crude oil returns have both positive and negative trends. Moreover, the optimal hedge ratios and optimal portfolio weights of crude oil across different assets and market portfolios are evaluated in order to provide important policy implications for risk management in crude oil markets.

Salisu, Afees A.; Fasanya, Ismail O.

2013-01-01

In this paper, we provide two main innovations: (i) we analyze oil prices of two prominent markets namely West Texas Intermediate (WTI) and Brent using the two recently developed tests by Narayan and Popp (2010) and Liu and Narayan, 2010 both of which allow for two structural breaks in the data series; and (ii) the latter method is modified to include both symmetric and asymmetric volatility models. We identify two structural breaks that occur in 1990 and 2008 which coincidentally correspond to the Iraqi/Kuwait conflict and the global financial crisis, respectively. We find evidence of persistence and leverage effects in the oil price volatility. While further extensions can be pursued, the consideration of asymmetric effects as well as structural breaks should not be jettisoned when modelling oil price volatility. - Highlights: ► We analyze oil price volatility using NP (2010) and LN (2010) tests. ► We modify the LN (2010) to account for leverage effects in oil price. ► We find two structural breaks that reflect major global crisis in the oil market. ► We find evidence of persistence and leverage effects in oil price volatility. ► Leverage effects and structural breaks are fundamental in oil price modelling.

2017-07-15

The global volatile profile of commercial virgin olive oils and flavoured olive oils with aromatic/medicinal plants, was established using liquid-liquid microextraction (LLME) and headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-quadrupole mass spectrometry (GC-qMS). More than 60 volatile organic compounds (VOCs belonging to different groups were identified using both methods. Olive oils volatile profile was slightly influenced by maceration process, which occurred at room temperature (20±2°C) for 15days. The predominant differences were observed in terpenoids group, since some of them were only identified in the flavoured olive oils, while others showed an increase with the maceration process. VOCs mass transfer from plants to olive oils could explain the observed results. Principal components analysis (PCA) applied to LLME/GC-qMS data allowed to distinguish the olive oils. The flavoured oils would increase the use of olive oil among consumers as consequence of the improvement of its aromatic profile and healthy properties. Copyright © 2017 Elsevier Ltd.

Cunado, Juncal; Jo, Soojin; Perez de Gracia, Fernando

2015-01-01

This paper analyzes the macroeconomic impact of structural oil shocks in four of the top oil-consuming Asian economies, using a VAR model. We identify three different structural oil shocks via sign restrictions: an oil supply shock, an oil demand shock driven by global economic activity and an oil-specific demand shock. The main results suggest that economic activity and prices respond very differently to oil price shocks depending on their types. In particular, an oil supply shock has a limited impact, while a demand shock driven by global economic activity has a significant positive effect in all four Asian countries examined. Our finding also includes that policy tools such as interest rates and exchange rates help mitigating the effects of supply shocks in Japan and Korea; however, they can be more actively used in response to demands shocks. - Highlights: • We analyze the effects of three structural oil price shocks on Asian economies. • Supply shocks have limited impact on the economic activity of Asian economies examined. • Demand shocks due to economic activity boosts GDP of all economies. • CPIs in India and Indonesia were only marginally affected by oil price shocks. • Monetary and exchange rate tools help mitigating supply shocks in Korea and Japan.

Modeling the relationship between the oil price and global food prices

The growth of corn-based ethanol production and soybean-based bio-diesel production following the increase in the oil prices have significantly affect the world agricultural grain productions and its prices. The main purpose of this paper is to investigate the relationships between the crude oil price and the global grain prices for corn, soybean, and wheat. The empirical results show that the change in each grain price is significantly influenced by the changes in the crude oil price and other grain prices during the period extending from the 3rd week in 2005 to the 20th week in 2008 which implies that grain commodities are competing with the derived demand for bio-fuels by using soybean or corn to produce ethanol or bio-diesel during the period of higher crude oil prices in these recent years. The subsidy policies in relation to the bio-fuel industries in some nations engaging in bio-fuel production should be considered to avoid the consequences resulting from high oil prices. (author)

Highlights: • Hydrogen solubility was measured in four tall oil fractions between 373 and 597 K. • Continuous flow synthetic isothermal and isobaric method was used. • A Henry’s law model was developed for the distilled tall oil fractions. • The complex composition of the samples was analyzed and is presented. - Abstract: Knowledge of hydrogen solubility in tall oil fractions is important for designing hydrotreatment processes of these complex nonedible biobased materials. Unfortunately measurements of hydrogen solubility into these fractions are missing in the literature. This work reports hydrogen solubility measured in four tall oil fractions between 373 and 597 K and at pressures from 5 to 10 MPa. Three of the fractions were distilled tall oil fractions their resin acids contents are respectively 2, 20 and 23 in mass-%. Additionally one fraction was a crude tall oil (CTO) sample containing sterols as the main neutral fraction. Measurements were performed using a continuous flow synthetic isothermal and isobaric method based on the visual observation of the bubble point. Composition of the flow was changed step-wise for the bubble point composition determination. We assume that the tall oil fractions did not react during measurements, based on the composition analysis performed before and after the measurements. Additionally the densities of the fractions were measured at atmospheric pressure from 293.15 to 323.15 K. A Henry’s law model was developed for the distilled tall oil fractions describing the solubility with an absolute average deviation of 2.1%. Inputs of the solubility model are temperature, total pressure and the density of the oil at 323.15 K. The solubility of hydrogen in the CTO sample can be described with the developed model with an absolute average deviation of 3.4%. The solubility of hydrogen increases both with increasing pressure and/or increasing temperature. The more dense fractions of the tall oil exhibit lower hydrogen

This conference presentation examined global oil market development and the role of Asian demand. It discussed plateau change versus cyclical movement in the global oil market; supply and demand issues of OPEC and non-OPEC oil; if high oil prices reduce demand; and the Asian oil picture in the global context. Asian oil demand has accounted for about 50 per cent of the global incremental oil market growth. The presentation provided data charts in graphical format on global and Asia-Pacific incremental oil demand from 1990-2005; Asia oil demand growth for selected nations; real GDP growth in selected Asian countries; and, Asia-Pacific oil production and net import requirements. It also included charts in petroleum product demand for Asia-Pacific, China, India, Japan, and South Korea. Other data charts included key indicators for China's petroleum sector; China crude production and net oil import requirements; China's imports and the share of the Middle East; China's oil exports and imports; China's crude imports by source for 2004; China's imports of main oil products for 2004; India's refining capacity; India's product balance for net-imports and net-exports; and India's trade pattern of oil products. tabs., figs

Transit and Globalization of the National Oil and Gas Business

Sekulic, G.; Tomljenovic, D.

2001-01-01

Energy transit plays a significant role in the energy development and globalization of the energy economy due to the dependence of the countries of large energy consumers on the energy import and the increase of export from the regions which do not have a direct connection with these consumers. In such circumstances huge amounts of energy cross several borders on their way from energy producers to energy consumers ''facing'' the risks of different political systems as well as different economic, legislative and social conditions together with environment protection conditions. With the purpose of reducing such and other risks and increasing the security level of consumer supply as well as the economic results in the energy sector, huge efforts are being made in creating market, non-discriminatory and transparent transit conditions through international treaties, agreements, conventions, protocols and similar. Owing to its geographical position, especially on the Mediterranean, the Republic of Croatia is an interesting transit country, but until now it profited only partially from this advantage. By constructing new gas pipelines and new connections of the existing oil pipeline with the European network both for the needs of local supply and transit, and according to the adopted international obligations on the conditions of the access to available capacities, construction of new capacities, market pricing, environment protection and other, oil and gas transit through this Croatia of Ours will be increased and further integration of oil and gas economy into the globalization processes will be speeded up.(author)

The purpose of this study is to investigate the impacts of crude oil price variations on the Turkish stock market returns. We have employed vector autoregression (V AR) model using daily observations of Brent crude oil prices and Istanbul Stock Exchange National Index (ISE- 1 00) returns for the period between January 2, 1990 and November 1, 2011. We have also tested the relationship between oil prices and stock market returns under global liquidity conditions by incorporating a liquidity proxy variable, Chicago Board of Exchange's (CBOE) S and P 500 market volatility index (VIX), into the model. Variance decomposition test results suggest little empirical evidence that crude oil price shocks have been rationally evaluated in the Turkish stock market. Rather, it was global liquidity conditions that were found to account for the greatest amount of variation in stock market returns.

A quantitative global skin-friction measurement technique is proposed. An oil-film is doped with a luminescent molecule and thereby made to fluoresce in order to resolve oil-film thickness, and Particle Image Surface Flow Visualization is used to resolve the velocity field of the surface of the oil-film. Skin-friction is then calculated at location x as (x )xh, where x is the displacement of the surface of the oil-film and is the dynamic viscosity of the oil. The data collection procedure and data analysis procedures are explained, and preliminary experimental skin-friction results for flow over the wing of the CRM are presented.

Applying network tools on predicting and warning the systemic risks provides a novel avenue to manage risks in financial markets. Here, we construct a series of global crude oil correlated networks based on the historical 57 oil prices covering a period from 1993 to 2012. Two systemic risk indicators are constructed based on the density and modularity of correlated networks. The local maximums of the risk indicators are found to have the ability to predict the trends of oil prices. In our sample periods, the indicator based on the network density sends five signals and the indicator based on the modularity index sends four signals. The four signals sent by both indicators are able to warn the drop of future oil prices and the signal only sent by the network density is followed by a huge rise of oil prices. Our results deepen the application of network measures on building early warning models of systemic risks and can be applied to predict the trends of future prices in financial markets.

Global resources and energy trade. An overview for coal, natural gas, oil and uranium

Energy Technology Data Exchange (ETDEWEB)

Remme, U.; Blesl, M.; Fahl, U.

2007-07-15

Despite efforts to improve energy effi-ciency and increase the usage of renewable energy carriers, fossil fuels and nuclear energy will continue to be important sources of global energy supply for the coming decades. Present global oil and gas supply is characterized by a concentration of production in a few world areas, mainly the Middle East and the Former Soviet Union, and a transport from these regions to the industrialized countries. Depletion of conventional reserves, especially oil, in combination with a surge for energy in emerging economies, as China and India, how-ever, is expected to change this picture in the future: unconventional resources in other world regions may be exploited to cover the surge energy demand, infrastructure for energy transport along new routes may have to be established. To provide a data base for such ques-tions, this report gives an overview of the current global resource situation for coal, natural gas, oil and uranium. In the first part, an assessment of the con-ventional and unconventional reserves and resources as well as their supply costs is given for the different regions of the world. The second part describes the current energy trade infrastructure between world regions and estimates the costs for existing and new trade links between these regions. (orig.)

World Energy Balance Outlook and OPEC Production Capacity: Implications for Global Oil Security

Directory of Open Access Journals (Sweden)

Azadeh M. Rouhani

2012-07-01

Full Text Available The imbalance between energy resource availability, demand, and production capacity, coupled with inherent economic and environmental uncertainties make strategic energy resources planning, management, and decision-making a challenging process. In this paper, a descriptive approach has been taken to synthesize the world’s energy portfolio and the global energy balance outlook in order to provide insights into the role of Organization of Petroleum Exporting Countries (OPEC in maintaining “stability” and “balance” of the world’s energy market. This synthesis illustrates that in the absence of stringent policies, i.e., if historical trends of the global energy production and consumption hold into the future, it is unlikely that non-conventional liquid fuels and renewable energy sources will play a dominant role in meeting global energy demand by 2030. This should be a source of major global concern as the world may be unprepared for an ultimate shift to other energy sources when the imminent peak oil production is reached. OPEC’s potential to impact the supply and price of oil could enable this organization to act as a facilitator or a barrier for energy transition policies, and to play a key role in the global energy security through cooperative or non-cooperative strategies. It is argued that, as the global energy portfolio becomes more balanced in the long run, OPEC may change its typical high oil price strategies to drive the market prices to lower equilibria, making alternative energy sources less competitive. Alternatively, OPEC can contribute to a cooperative portfolio management approach to help mitigate the gradually emerging energy crisis and global warming, facilitating a less turbulent energy transition path while there is time.

Global brain storming : oil companies increasingly tap collective intelligence to overcome technology hurdles

This article described a novel exploration approach that Toronto-based Goldcorp Inc. took a decade ago when it placed its geological data on the web for a mass collaboration effort among the global community of geologists to identify potential drilling sites. The move resulted in the identification of 110 targets, of which half were entirely new to Goldcorp, and of which four in five struck considerable quantities of gold. The article emphasized that the computer network offers a power that has not yet been fully tapped. It described other companies that have followed suite in finding solutions to proprietary challenges, including Schlumberger, Deloro Resources Ltd., Electro-Petroleum Inc., and Proctor and Gamble Inc. among others. The Web 2.0, which serves as a platform for a range of applications, can also be used for open-source science or global brainstorming. While the idea of open innovation was a novelty a year or two ago, it has now become a necessity. InnoCentive solved a long-standing oil spill problem when a chemist from the web with no ties to the oil industry suggested a way to handle the spill. The Cordova, Alaska-based Oil Spill Recovery Institute has also sought solutions for oil spills and novel boom designs. It was concluded that at a time when research and development budgets in the petroleum industry are being cut, open innovation facilitators stand to benefit. This cross-industry collaboration does not involve geoscientists alone. Rather, it includes people from completely different fields of expertise, experience or education who can add to the real issues that the oil industry needs to address and change. 1 ref.

Coal and Oil: The Dark Monarchs of Global Energy: Understanding Supply and Extraction Patterns and their Importance for Future Production

International Nuclear Information System (INIS)

Hoeoek, Mikael

2010-01-01

The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind. This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil. Both coal and oil are finite resources, created over long time scales by geological processes. It is thus impossible to extract more fossil fuels than geologically available. In other words, there are limits to growth imposed by nature. The concept of depletion and exhaustion of recoverable resources is a fundamental question for the future extraction of coal and oil. Historical experience shows that peaking is a well established phenomenon in production of various natural resources. Coal and oil are no exceptions, and historical data shows that easily exploitable resources are exhausted while more challenging deposits are left for the future. For oil, depletion can also be tied directly to the physical laws governing fluid flows in reservoirs. Understanding and predicting behaviour of individual fields, in particularly giant fields, are essential for understanding future production. Based on comprehensive databases with reserve and production data for hundreds of oilfields, typical patterns were found. Alternatively, depletion can manifest itself indirectly through various mechanisms. This has been studied for coal. Over 60% of the global crude oil production is derived from only around 330 giant oilfields, where many of them are becoming increasingly mature. The annual decline in existing oil production has been determined to be around 6% and it is unrealistic that this will be offset by new field developments, additional discoveries or unconventional oil. This implies that the peak of the oil age is here. For coal a similar picture emerges, where 90% of the global coal production originates

The formation of the global natural gas industry: definition, constraints and challenges; A formacao da industria global de gas natural: definicao, condicionantes e desafios

Energy Technology Data Exchange (ETDEWEB)

Mathias, Melissa Cristina Pinto Pires

2008-03-15

This study aims to investigate the real possibilities for the natural gas industry to become a global energy industry. So, it is necessary to define what global energy industry really means. In order to do a comparative analysis between the oil and natural gas industries, it is necessary to define three distinct stages of the evolution of an energy industry, namely internationalization, mundialization and globalization. This study analyzes the evolution of the oil industry trying to identify the main aspects that promoted changes and transformed the oil business into a global industry. Then, the evolution of the natural gas industry is analyzed, looking for similarities between the structural changes in both industries, and trying to determine what is the current stage of the natural gas industry. Despite the increase in the natural gas international trade and the prospects of growth of natural gas demand, there are still some challenges for this industry to effectively become global. Some of the challenges are the need of investments in production infrastructure, transportation and distribution sectors, the access to the main reserves, the uncertainty related to the demand evolution and the possible creation of a natural gas producers cartel, like the Organization of the Petroleum Exporting Countries (OPEC).

Zamith, R.; Moutinho Dos Santos, E.

2000-01-01

It is recognized the economic benefits that might follow the opening process of the Brazilian oil and natural gas industry, which shall experience a fast expansion with the arrival of national and international private investors. However, we should not neglect the broader impact of this process on the future development of all that cluster of national agents that lived around and served the former national oil monopoly, managed by the Brazilian National Oil Company, Petrobras. This work focuses on this larger perspective, discussing about the capacity of Brazil to sustain and expand its competitiveness in the oil business as well as to obtain the maximum economic development from the exploration of its oil and gas reserves. We adopt the work of Michael Porter, from the University of Harvard, about the Competitive Advantage of Nations, as a theoretical model to analyze the Competitive Advantage of Brazil in the global oil industry. By introducing the concept of ''oil diamond'', adapted from the notion introduced by this author, we develop a new understanding of national competitiveness in the oil sector. In this paper, we present the general model as well as a brief characterization of the results found for Brazil Subsequently, we focus on just one leg of the model, for which we discuss, with more detail, about the competitive condition of the country in the opening-up scenario. This leg regards the so-called supporting and supplementary industries that constitute what is denominated in the French tradition the ''para petroleum'' industry. We analyze the conditions for the Brazilian domestic ''para petroleum industry'' to survive and grow in the new competitive environment. (authors)

Global warming and oil: Can nuclear power make a difference?

International Nuclear Information System (INIS)

Bodansky, D.

1991-01-01

A responsible energy policy, for the United States and the world, must address two needs: to restrain the rate of fossil fuel consumption, and to reduce the consumption of oil. Unless the first is accomplished, the world may experience major climate changes, some perhaps disastrous, from the buildup of carbon dioxide and other greenhouse gases. Unless the second is met, we face recurring threats of economic disruption and war, due to the dangerous concentration of the world's oil resources in the Persian Gulf region. Nuclear power has long been cited as a possible answer to these needs. Mr. Bodansky takes a fresh look at the contribution nuclear power could make, in the light of our increased awareness of global warming dangers and the renewed reminders of the instabilities of oil markets. He notes, however, that the basic objections to nuclear power remain. They are well-known, stemming from concerns about reactor safety, waste disposal, nuclear proliferation, and cost. These are old but continuing controversies, involving a tangle of technical, political, social, and economic issues. If nuclear power is to be revived, these concerns clearly must be addressed. 1 fig., 7 tabs

The impacts of global oil price shocks on China's fundamental industries

Wang, Xiao; Zhang, Chuanguo

2014-01-01

This paper investigated the impacts of oil price shocks on China's fundamental industries. In order to analyze the reactions of different industries to oil price shocks, we focused on four fundamental industries: grains, metals, petrochemicals and oil fats. We separated the oil price shocks into two parts, positive and negative parts, to investigate how commodity markets react when oil prices go up and down. We further studied the extreme price movements, called jumps, existing in the oil markets and how jump behavior has affected China's commodity markets. Our results suggest that asymmetric effects of oil price shocks did exist in the four markets and the negative oil price shocks had stronger influences on the four markets in China. The petrochemicals market suffered most from the oil price shocks, and the grains market was least sensitive to the shocks. When jumps occurred in the crude oil market, the four commodity markets would be affected differently. The oil fats market and petrochemicals market tended to “overreact” to jumps. - Highlights: • We investigate the impacts of oil price shocks on China's fundamental industries. • Jump behavior does exist in the crude oil market. • The impacts of oil price shocks are asymmetric. • China's four commodity markets are affected by the jump behavior

Changes in the Global Energy System: Implications for China's International Strategic Environment

Directory of Open Access Journals (Sweden)

Zhang Chi

2015-12-01

Full Text Available This article briefly discusses major reasons for the slump of international oil prices and provides a prediction for the future development of international oil prices, before analyzing the three factors leading to significant changes of the global energy system, namely the eastward shift of the world energy consumption centre, the emergence of the United States as a major oil producer and the dramatic waning of the Organization of Petroleum Exporting Countries’ (OPEC influence. These factors and developments are shaping a new order of the global energy strategic landscape and exerting profound influence on China’s international strategic environment. In the foreseeable future, these changes of the global energy system would bring China more uncertainties regarding the country’s oil imports from the Middle East, more strategic pressure from the United States, while promoting China’s leverage on the global energy system and international relations.

Ali Ibrahim Al-Naimi is the former Saudi oil minister - and OPEC kingpin - a position he held for the two decades between August 1995 and May 2016. He was born into extreme poverty as a nomadic Bedouin in the 1930s, just as US companies were discovering vast quantities of oil under Arabian deserts. From his first job as a shepherd boy to his appointment to one of the most powerful political and economic jobs in the world, Out of the Desert charts Al-Naimi\\'s extraordinary rise to power.

The Poisoned Chalice: Oil and Macroeconomics in Brazil (1967-2003)

Science.gov (United States)

Biasetto, Bruno Henz

This dissertation analyzes the development of the Brazilian oil industry and its impact on the economic development of Brazil from the beginning of the "Brazilian Miracle" (1968-1973) to the end of the Fernando Henrique Cardoso's second term as president (1995-2002). The dissertation explores the closely intertwined nature of Brazil's oil industry and its macroeconomic development, shedding new light on the history of Petrobras (the Brazilian state oil company), and on other key topics of Brazilian economic history, including the Debt Crisis of the 1980s and the role of neoliberalism in Brazil. The argument is that oil policy shaped the national economy and the Brazilian state in this period. Attention to the oil industry, and to Petrobras in particular, was crucial to the establishment of diplomatic and economic policy, and to conflict within the Brazilian state. Finally, this dissertation seeks to illuminate Brazil's place in the global oil industry and how that has shaped Brazil's global economic standing.

Lifting the US crude oil export ban: A numerical partial equilibrium analysis

Langer, Lissy; Huppmann, Daniel; Holz, Franziska

2016-01-01

The upheaval in global crude oil markets and the boom in shale oil production in North America brought scrutiny on the US export ban for crude oil from 1975. The ban was eventually lifted in early 2016. This paper examines the shifts of global trade flows and strategic refinery investments in a spatial, game-theoretic partial equilibrium model. We consider detailed oil supply chain infrastructure with multiple crude oil types, distinct oil products, as well as specific refinery configurations and modes of transport. Prices, quantities produced and consumed, as well as infrastructure and refining capacity investments are endogenous to the model. We compare two scenarios: an insulated US crude oil market, and a counter-factual with lifted export restrictions. We find a significant expansion of US sweet crude exports with the lift of the export ban. In the US refinery sector, more (imported) heavy sour crude is transformed. Countries importing US sweet crude gain from higher product output, while avoiding costly refinery investments. Producers of heavy sour crude (e.g. the Middle East) are incentivised to climb up the value chain to defend their market share and maintain their dominant position. - Highlights: • We study the impacts of lifting the US crude ban on global oil flows and investments. • We find massive expansion of US sweet crude oil exports. • We analyze the resulting welfare effects for US producers, refiners and consumers. • We indicate the changes on global trade patterns. • We conclude that lifting the ban is the right policy for the US and the global economy.

An oil-sick global economy?

International Nuclear Information System (INIS)

Anon.

2004-01-01

Since early 2004, oil prices have increased by 50% as a combined result of a demand shock, tensions on production capacities and supply disruptions. The surplus of wealth from oil importing to exporting countries nears 100 bn dollars (0.3% of OECD GDP) in the whole year. Households' real income should decrease by 0.3 point in the Euro zone and by 0.5 point in the US. According to our oil price forecasts (33 dollars a barrel by the end of 2005), GDP growth should be reduced by 0.4 point in 2004-2005. Should prices remain at 50 dollars throughout 2005, growth in industrial countries will be further impaired (0.6 point with a monetary policy response), but developing economies will suffer more. Oil producing countries should increase their imports and the reintroduction of petro dollars on financial markets should hold international interest rates down

Global climate change implications for coastal and offshore oil and gas development

International Nuclear Information System (INIS)

Burkett, Virginia

2011-01-01

The discussion and debate about climate change and oil and gas resource development has generally focused on how fossil fuel use affects the Earth's climate. This paper explores how the changing climate is likely to affect oil and gas operations in low-lying coastal areas and the outer continental shelf. Oil and gas production in these regions comprises a large sector of the economies of many energy producing nations. Six key climate change drivers in coastal and marine regions are characterized with respect to oil and gas development: changes in carbon dioxide levels and ocean acidity, air and water temperature, precipitation patterns, the rate of sea level rise, storm intensity, and wave regime. These key drivers have the potential to independently and cumulatively affect coastal and offshore oil and gas exploration, production, and transportation, and several impacts of climate change have already been observed in North America. - Highlights: ► Climate change effects on coastal and offshore energy development have been observed in some regions. ► Key drivers include changes in temperature, precipitation, sea level rise, storm intensity and wave regime. ► These can independently and cumulatively affect coastal and offshore exploration, production, and transportation. ► A methodical vulnerability and impact assessment is needed to support adaptation in this sector of the global economy.

Widder, Lukas; Brennerb, Josef; Huttera, Herbert

2014-01-01

To develop new products and to apply measures of quality control quick and simple accessibility of additive composition in automo- tive lubrication is important. The aim of this study was to investigate the possibility of analyzing organic friction modifier additives by means of atmospheric pressure matrix-assisted laser desorption/ionization mass spectrometry [AP-MALDI-MS] from lubricant solu- tions without the use of additional separation techniques. Analyses of selected friction modifier ethoxylated tallow amines and oleic acid amide were compared using two ionization methods, positive-ion electrospray ionization (ESI) and AP-MALDI, using a LTQ Orbitrap mass spectrometer. Pure additives were characterized from solvent solutions, as well as from synthetic and mineral base oil mixtures. Detected ions of pure additive samples consisted mainly of [M + H]+, but also alkaLi metal adducts [M + Na]+ and [M + K]+ could be seen. Characterizations of blends of both friction modifiers from the base oil mixtures were carried out as well and showed significant inten- sities for several additive peaks. Thus, this work shows a method to directly analyze friction modifier additives used in the automotive industry from an oil blend via the use of AP-MALDI without any further separation steps. The method presented will further simplify the acquisition of data on lubricant composition and additives. Furthermore, it allows the perspective of analyzing additive reaction products directly from formulated oil blends.

Analyzing the New York Global History and Geography Exam

Directory of Open Access Journals (Sweden)

S. G. Grant

2001-10-01

Full Text Available Education Week's report "Quality Counts" judges New York State's curriculum and assessment policy efforts to be an "A." Surface-level reviews such as "Quality Counts" tell something about the workings of state policy, but they are more useful as snapshots than as well-developed portraits of curriculum and assessment change. In this article, I analyze the new New York State Global History and Geography standards and tests using a set of social studies-specific criteria which inquire deeply into the implications for real instructional change. From that vantage, I argue that New York's policy efforts, while seemingly well-intentioned and reflective of surface-level change, fail to promote powerful teaching and learning in social studies. Teachers intent on producing ambitious teaching and learning will find little to interfere with their efforts. But as a set of reforms intended to encourage substantive change, the new global history test falls short.

[Development of a portable mid-infrared rapid analyzer for oil concentration in water based on MEMS linear sensor array].

Aiming at the existing problems such as weak environmental adaptability, low analytic efficiency and poor measuring repeatability in the traditional spectral oil analyzers, the present paper designed a portable mid-infrared rapid analyzer for oil concentration in water. To reduce the volume of the instrument, the non-symmetrical folding M-type Czerny-Turner optical structure was adopted in the core optical path. With a periodically rotating chopper, controlled by digital PID algorithm, applied for infrared light modulation, the modulating accuracy reached ±0.5%. Different from traditional grating-scanning spectrophotometers, this instrument used a fixed grating for light dispersion and avoided rotating error in the course of the measuring procedures. A new-type MEMS infrared linear sensor array was applied for modulated spectral signals detection, which improved the measuring efficiency remarkably. Optical simulation and experimental results indicate that the spectral range is 2 800 - 3 200 cm(-1), the spectral resolution is 6 cm(-1) (@3 130 cm(-1)), and the signal to noise ratio is up to 5 200 : 1. The acquisition time is 13 milliseconds per spectrogram, and the standard deviation of absorbance is less than 3 x 10(-3). These performances meet the standards of oil concentration measurements perfectly. Compared with traditional infrared spectral analyzers for oil concentration, the instrument demonstrated in this paper has many advantages such as smaller size, more efficiency, higher precision, and stronger vibration & moisture isolation. In addition, the proposed instrument is especially suitable for the environmental monitoring departments to implement real-time measurements in the field for oil concentration in water, hence it has broad prospects of application in the field of water quality monitoring.

The author first describes how oil will disappear from non-producing countries, notably France and Europe and will therefore lead to an energy crisis. He outlines that renewable energies will have a weak contribution in the replacement of fossil energies (in this case, oil and gas). To illustrate these trends, the author proposes an appendix which presents and discusses the evolution of global consumption of fossil fuels, the evolution of production of different oil grades, a forecast of global oil demand by 2035, evolutions of productions and exports. Another appendix discusses additional issues on oil: the meaning of reserves, solutions for France in case of shortage of oil, the world oil situation (USA, China, Russia, the European Union, Japan)

The impact of global oil price shocks on China’s bulk commodity markets and fundamental industries

Zhang, Chuanguo; Chen, Xiaoqing

2014-01-01

This paper investigated the reaction of aggregate commodity market to oil price shocks and also explored the effects of oil price shocks on China's fundamental industries: metals, petrochemicals, grains and oilfats. We separated the volatilities of oil price into expected, unexpected and negatively expected categories to identify how oil prices influence bulk commodity markets. We contrasted the results between different periods and among classified indices, in order to discover the significant changes in recent years and the differences at an industry level. Our results indicate that the aggregate commodity market was affected by both expected and unexpected oil price volatilities in China. The impact of unexpected oil price volatilities became more complex after 2007. The metals and grains indices did not significantly respond to the expected volatility in oil prices, in contrast to the petrochemicals and oilfats indices. These results not only contribute to advancing the existing literature, but also merit particular attention from policy makers and market investors in China. - Highlights: • We investigated the impact of global oil price shocks on China’s bulk commodity markets and fundamental industries. • The aggregate commodity market was affected by both expected and unexpected oil price volatilities. • The impact of unexpected oil price volatilities became more complex after 2007. • The metals and grains indices did not significantly respond to the expected volatility in oil prices

Linear least-squares method for global luminescent oil film skin friction field analysis

Science.gov (United States)

Lee, Taekjin; Nonomura, Taku; Asai, Keisuke; Liu, Tianshu

2018-06-01

A data analysis method based on the linear least-squares (LLS) method was developed for the extraction of high-resolution skin friction fields from global luminescent oil film (GLOF) visualization images of a surface in an aerodynamic flow. In this method, the oil film thickness distribution and its spatiotemporal development are measured by detecting the luminescence intensity of the thin oil film. From the resulting set of GLOF images, the thin oil film equation is solved to obtain an ensemble-averaged (steady) skin friction field as an inverse problem. In this paper, the formulation of a discrete linear system of equations for the LLS method is described, and an error analysis is given to identify the main error sources and the relevant parameters. Simulations were conducted to evaluate the accuracy of the LLS method and the effects of the image patterns, image noise, and sample numbers on the results in comparison with the previous snapshot-solution-averaging (SSA) method. An experimental case is shown to enable the comparison of the results obtained using conventional oil flow visualization and those obtained using both the LLS and SSA methods. The overall results show that the LLS method is more reliable than the SSA method and the LLS method can yield a more detailed skin friction topology in an objective way.

Quest for Middle East oil: the US versus the Asia-Pacific region

International Nuclear Information System (INIS)

Salameh, Mamdouh G.

2003-01-01

Two very powerful geopolitical factors will decisively determine whether the quest for Middle East oil (mainly Gulf oil) could enhance the global oil security or could lead to oil supply disruptions and also instability and conflict in the Asia-Pacific region. The two factors are the United States' growing dependence on oil imports from the Middle East and the Asia-Pacific region's thirst for oil and the increasingly likely Chinese dependence on oil from the region. The Asia-Pacific countries are increasingly growing concerned about their ability to supply enough oil to fuel future economic growth. The region's phenomenal economic growth up to July 1997 and its economic recovery since then, and its steadily rising energy needs lend urgency to the question of how the region would meet its considerable energy challenges. This paper will endeavour to analyze the impact of this growing dependence on Middle East oil, on global oil supplies, the price of oil and global oil security. It will argue that such dependence on a volatile region like the Middle East and the perception of scarcer energy resources in the Asia-Pacific region, have the potential to lead to conflict in both regions unless these issues are dealt with in geoeconomic rather than geostrategic terms. The paper will strongly express the view that potential conflicts can be resolved not by force but through markets and investment and also through the diversification of energy sources and the promotion of alternative energy development and use across the region

Giant Oil Fields - The Highway to Oil: Giant Oil Fields and their Importance for Future Oil Production

International Nuclear Information System (INIS)

Robelius, Fredrik

2007-01-01

Since the 1950s, oil has been the dominant source of energy in the world. The cheap supply of oil has been the engine for economic growth in the western world. Since future oil demand is expected to increase, the question to what extent future production will be available is important. The belief in a soon peak production of oil is fueled by increasing oil prices. However, the reliability of the oil price as a single parameter can be questioned, as earlier times of high prices have occurred without having anything to do with a lack of oil. Instead, giant oil fields, the largest oil fields in the world, can be used as a parameter. A giant oil field contains at least 500 million barrels of recoverable oil. Only 507, or 1 % of the total number of fields, are giants. Their contribution is striking: over 60 % of the 2005 production and about 65 % of the global ultimate recoverable reserve (URR). However, giant fields are something of the past since a majority of the largest giant fields are over 50 years old and the discovery trend of less giant fields with smaller volumes is clear. A large number of the largest giant fields are found in the countries surrounding the Persian Gulf. The domination of giant fields in global oil production confirms a concept where they govern future production. A model, based on past annual production and URR, has been developed to forecast future production from giant fields. The results, in combination with forecasts on new field developments, heavy oil and oil sand, are used to predict future oil production. In all scenarios, peak oil occurs at about the same time as the giant fields peak. The worst-case scenario sees a peak in 2008 and the best-case scenario, following a 1.4 % demand growth, peaks in 2018

Market potential for Canadian crude oil

1997-01-01

Future key markets for Canadian crude were evaluated, and probable flow volumes and prices were identified. Key concerns of market participants such as pricing, alternative crude sources, pipeline tariffs and crude quality, were examined. An overview of the competition faced by Canadian crude supply in global markets was presented. World crude oil supply and demand was discussed. US and Canadian crude oil supply (2000 to 2010), refinery demand for light and heavy crudes, existing future crude oil and refined product pipeline infrastructure, and pricing implications of changing crude oil flows were analyzed. The general conclusion was that the US market will continue to provide growing markets for Canadian crude oil, and that the Canadian supply to fulfill increased export requirements will be available due to the combined effects of increasing heavy crude supply, growing production from the east coast offshore, and recent and ongoing pipeline expansions and additions. 20 refs., 64 tabs., 42 figs

Modeling global and local dependence in a pair of commodity forward curves with an application to the US natural gas and heating oil markets

International Nuclear Information System (INIS)

Ohana, Steve

2010-01-01

The goal of this paper is to present a model for the joint evolution of correlated commodity forward curves. Each forward curve is directed by two state variables, namely slope and level, and the model is meant to capture both the local and global dependence structures between slopes and levels. Our framework can be interpreted as an extension of the concept of cointegration to forward curves. The model is applied to a US database of heating oil and natural gas futures prices over the period February 2000-February 2009. We find the long-run slope and level relationships between natural gas and heating oil markets, analyze the lead and lag properties between the two energy commodities, the volatilities and correlations between their daily co-movements and evaluate the robustness of these observations to the turmoil experienced by energy markets since 2003.

From Paris to the End of Oil

Directory of Open Access Journals (Sweden)

Dag Harald Claes

2016-09-01

Full Text Available This article discusses the possibilities and obstacles for a cost-effective implementation of policies that will lead to a significant reduction in global CO2 emissions from the use of oil. The structural conditions and economic consequences of changing national or regional energy systems vary dramatically. In addition, there are a large number of actors with strong interests along the energy value chain that may potentially halt, delay or alter the implementation of the Paris treaty. We analyze these issues by first locating oil in the overall energy system, then identifying possibilities and obstacles at various stages of the oil value chain, and finally by contextualizing global oil by discussing whether and how it may be affected by geopolitics and regional conflict. In brief, our argument is that developments in consumption volumes and patterns will be most important. Market forces are vital, but they are influenced by politics and public policy outcomes. Transportation is the most important sector for oil consumption, with changes in transport behavior, modes and technology being vital drivers. The behavior of investors will be a decisive factor in shaping the production side of the oil system. If investments go down as a response to lasting low oil prices and/or because investors decide to turn to green economy options, the supply of oil will logically shrink. On the other hand, the growth and development aspirations of a rapidly growing population in developing countries are likely to stimulate demand and thus increase exploration, production and subsequently the price. Finally, we emphasize the importance of (geopolitics influencing all aspects of the value chain of oil.

The Role of Dietary Extra Virgin Olive Oil and Corn Oil on the Alteration of Epigenetic Patterns in the Rat DMBA-Induced Breast Cancer Model.

Directory of Open Access Journals (Sweden)

Cristina Rodríguez-Miguel

Full Text Available Disruption of epigenetic patterns is a major change occurring in all types of cancers. Such alterations are characterized by global DNA hypomethylation, gene-promoter hypermethylation and aberrant histone modifications, and may be modified by environment. Nutritional factors, and especially dietary lipids, have a role in the etiology of breast cancer. Thus, we aimed to analyze the influence of different high fat diets on DNA methylation and histone modifications in the rat dimethylbenz(aanthracene (DMBA-induced breast cancer model. Female Sprague-Dawley rats were fed a low-fat, a high corn-oil or a high extra-virgin olive oil (EVOO diet from weaning or from induction with DMBA. In mammary glands and tumors we analyzed global and gene specific (RASSF1A, TIMP3 DNA methylation by LUMA and bisulfite pyrosequencing assays, respectively. We also determined gene expression and enzymatic activity of DNA methyltransferases (DNMT1, DNMT3a and DNMT3b and evaluated changes in histone modifications (H3K4me2, H3K27me3, H4K20me3 and H4K16ac by western-blot. Our results showed variations along time in the global DNA methylation of the mammary gland displaying decreases at puberty and with aging. The olive oil-enriched diet, on the one hand, increased the levels of global DNA methylation in mammary gland and tumor, and on the other, changed histone modifications patterns. The corn oil-enriched diet increased DNA methyltransferase activity in both tissues, resulting in an increase in the promoter methylation of the tumor suppressor genes RASSF1A and TIMP3. These results suggest a differential effect of the high fat diets on epigenetic patterns with a relevant role in the neoplastic transformation, which could be one of the mechanisms of their differential promoter effect, clearly stimulating for the high corn-oil diet and with a weaker influence for the high EVOO diet, on breast cancer progression.

Global simulations of smoke from Kuwaiti oil fires and possible effects on climate

The Los Alamos Global Climate Model has bee used to simulate the global evolution of the Kuwaiti oil fire smoke and its potential effects on the climate. The initial simulations were done shortly before the fires were lit in January 1991. They indicated that such an event would not result in a Mini Nuclear Winter'' as some people were suggesting. Further simulations during the year suggested that the smoke could be responsible for subtle regional climate changes in the spring such as a 5 degree centigrade decrease in the surface temperature in Kuwait, a 10% decrease in precipitation in Saudi Arabia and a 10% increase in precipitation in the Tibetan Plateau region. These results are in qualitative agreement with the observations this year.

Lutz, Christian; Lehr, Ulrike; Wiebe, Kirsten S.

2012-01-01

Assuming that global oil production peaked, this paper uses scenario analysis to show the economic effects of a possible supply shortage and corresponding rise in oil prices in the next decade on different sectors in Germany and other major economies such as the US, Japan, China, the OPEC or Russia. Due to the price-inelasticity of oil demand the supply shortage leads to a sharp increase in oil prices in the second scenario, with high effects on GDP comparable to the magnitude of the global financial crises in 2008/09. Oil exporting countries benefit from high oil prices, whereas oil importing countries are negatively affected. Generally, the effects in the third scenario are significantly smaller than in the second, showing that energy efficiency measures and the switch to renewable energy sources decreases the countries' dependence on oil imports and hence reduces their vulnerability to oil price shocks on the world market. - Highlights: ► National and sectoral economic effects of peak oil until 2020 are modelled. ► The price elasticity of oil demand is low resulting in high price fluctuations. ► Oil shortage strongly affects transport and indirectly all other sectors. ► Global macroeconomic effects are comparable to the 2008/2009 crisis. ► Country effects depend on oil imports and productivity, and economic structures.

Most palm oil currently available in global markets is sourced from certified large-scale plantations. Comparatively little is sourced from (typically uncertified) smallholders. We argue that sourcing sustainable palm oil should not be determined by commercial certification alone and that the certification process should be revisited. There are so-far unrecognized benefits of sourcing palm oil from smallholders that should be considered if genuine biodiversity conservation is to be a foundation of 'environmentally sustainable' palm oil production. Despite a lack of certification, smallholder production is often more biodiversity-friendly than certified production from large-scale plantations. Sourcing palm oil from smallholders also alleviates poverty among rural farmers, promoting better conservation outcomes. Yet, certification schemes - the current measure of 'sustainability' - are financially accessible only for large-scale plantations that operate as profit-driven monocultures. Industrial palm oil is expanding rapidly in regions with weak environmental laws and enforcement. This warrants the development of an alternative certification scheme for smallholders. Greater attention should be directed to deforestation-free palm oil production in smallholdings, where production is less likely to cause large scale biodiversity loss. These small-scale farmlands in which palm oil is mixed with other crops should be considered by retailers and consumers who are interested in promoting sustainable palm oil production. Simultaneously, plantation companies should be required to make their existing production landscapes more compatible with enhanced biodiversity conservation. Copyright © 2017 Elsevier Ltd.

The Peruvian Amazon is culturally and biologically one of the most diverse regions on Earth. Since the 1920s oil exploration and extraction in the region have threatened both biodiversity and indigenous peoples, particularly those living in voluntary isolation. We argue that the phenomenon of peak oil, combined with rising demand and consumption, is now pushing oil extraction into the most remote corners of the world. Modern patterns of production and consumption and high oil prices are forcing a new oil exploratory boom in the Peruvian Amazon. While conflicts spread on indigenous territories, new forms of resistance appear and indigenous political organizations are born and become more powerful. The impacts of oil exploration and exploitation and indigenous resistance throughout the oil history of the Peruvian Amazon are reviewed here, focusing on the Achuar people in Rio Corrientes. The driving forces, impacts, and responses to the current oil exploration boom are analyzed from an environmental justice perspective. We conclude that, in a context of peak oil and growing global demand for oil, such devastating effects for minor quantities of oil are likely to increase and impact other remote parts of the world.

From 2010 to 2013, 763 soybean samples were collected from an extensive area of China. The correlations between seed compositions and climate data were analyzed. The contents of crude protein and water-soluble protein, total amount of protein plus oil, and most of the amino acids were positively correlated with an accumulated temperature ≥15 °C (AT15) and the mean daily temperature (MDT) but were negatively correlated with hours of sunshine (HS) and diurnal temperature range (DTR). The correlations of crude oil and most fatty acids with climate factors were opposite to those of crude protein. Crude oil content had a quadratic regression relationship with MDT, and a positive correlation between oil content and MDT was found when the daily temperature was soybean protein and oil contents. The study illustrated the effects of climate factors on soybean protein and oil contents and proposed agronomic practices for improving soybean quality in different regions of China. The results provide a foundation for the regionalization of high-quality soybean production in China and similar regions in the world.

Resources and future supply of oil

International Nuclear Information System (INIS)

Kjaerstad, Jan; Johnsson, Filip

2009-01-01

This paper examines global oil resources and the future global oil supply/demand balance. The paper builds upon several comprehensive databases designed during the work and considerable efforts have been made to review what must be considered the most reliable data. Global oil resources have been investigated on three levels; country, company and field levels. Although no decisive conclusions or quantitative assessments can be made with respect to the global oil resource base, remaining resources appear to be sufficient to meet demand up to 2030 as projected in the 2006 (and 2007) world energy outlook by the IEA. Significant resources have already been discovered beyond proven reserves, many prospective regions remain to be fully explored and there are vast volumes of recoverable unconventional oil. However, it is also concluded that global supply of oil probably will continue to be tight, both in the medium term as well as in the long term mainly as a consequence of above-ground factors such as investment constraints, geopolitical tensions, limited access to reserves and mature super-giant fields. Production of unconventional oil and synthetic fuels is not believed to significantly alter this situation. Although an increasing number of recent reports have indicated an imminent or 'soon to come' peak in global oil supply, it has not been found that any of these reports have contributed with any new information on oil resources or oil supply ability. Nevertheless, there is a distinct possibility that global oil production may peak or plateau in a relatively near future, not caused by limited resources but because too many factors over long time constrain investments into exploration and production. The lack of transparency within the oil industry obviously prevents any accurate analysis of future production and supply ability. Moreover, our ability to analyse the sector will become more difficult in the future as oil increasingly will have to be sourced from

Strategies for restoration of deep-water coral ecosystems based on a global survey of oil and gas regulations

Cordes, E. E.; Jones, D.; Levin, L. A.

2016-02-01

The oil and gas industry is one of the most active agents of the global industrialization of the deep sea. The wide array of impacts following the Deepwater Horizon oil spill highlighted the need for a systematic review of existing regulations both in US waters and internationally. Within different exclusive economic zones, there are a wide variety of regulations regarding the survey of deep-water areas prior to leasing and the acceptable set-back distances from vulnerable marine ecosystems once they are discovered. There are also varying mitigation strategies for accidental release of oil and gas, including active monitoring systems, temporary closings of oil and gas production, and marine protected areas. The majority of these regulations are based on previous studies of typical impacts from oil and gas drilling, rather than accidental releases. However, the probability of an accident from standard operations increases significantly with depth. The Oil & Gas working group of the Deep Ocean Stewardship Initiative is an international partnership of scientists, managers, non-governmental organizations, and industry professionals whose goal is to review existing regulations for the oil & gas industry and produce a best practices document to advise both developed and developing nations on their regulatory structure as energy development moves into deeper waters.

The overseas acquisitions and equity oil shares of Chinese national oil companies: A threat to the West but a boost to China's energy security?

International Nuclear Information System (INIS)

Zhang Zhongxiang

2012-01-01

This paper argues that both China and the Western countries need to de-politicize China's global quest for energy security. The Western politicians need to recognize that their rhetoric in relation to China's efforts to secure energy supplies overseas has done nothing but intensify China's fear that they might seek to deny China's access to the oil it needs for the development. China needs to reconsider its stance of distrusting global oil markets and to recognize that the reliance on aggressive acquisitions of overseas oil fields and equity oil production has been of little help in strengthening its energy security. Given that China's energy security depends increasingly and deeply on the stability of global oil markets and reliable and growing oil supplies to the market, China shares with other major oil importing countries profound common interests in maintaining and strengthening the stability of global oil markets and reducing the chance of potential disruptions to oil supply and the resulting damaging oil price shocks.

The future of oil supply.

Miller, Richard G; Sorrell, Steven R

2014-01-13

Abundant supplies of oil form the foundation of modern industrial economies, but the capacity to maintain and grow global supply is attracting increasing concern. Some commentators forecast a peak in the near future and a subsequent terminal decline in global oil production, while others highlight the recent growth in 'tight oil' production and the scope for developing unconventional resources. There are disagreements over the size, cost and recoverability of different resources, the technical and economic potential of different technologies, the contribution of different factors to market trends and the economic implications of reduced supply. Few debates are more important, more contentious, more wide-ranging or more confused. This paper summarizes the main concepts, terms, issues and evidence that are necessary to understand the 'peak oil' debate. These include: the origin, nature and classification of oil resources; the trends in oil production and discoveries; the typical production profiles of oil fields, basins and producing regions; the mechanisms underlying those profiles; the extent of depletion of conventional oil; the risk of an approaching peak in global production; and the potential of various mitigation options. The aim is to introduce the subject to non-specialist readers and provide a basis for the subsequent papers in this Theme Issue.

A wide body of research has characterized methane emissions from the oil and gas system in the US. In contrast, empirical data is limited for other significant oil and gas producing regions across the world. As a consequence, measuring and characterizing methane emissions across global oil and gas operations will be crucial to the design of effective mitigation strategies. Several countries have announced pledges to reduce methane emissions from this system (e.g., North America, Climate and Clean Air Coalition [CCAC] ministers). In the case of Canada, the federal government recently announced regulations supporting a 40-45% reduction of methane emissions from the oil and gas production systems. For these regulations to be effective, it is critical to understand the current methane emission patterns. We present results from a coordinated multiscale (i.e., airborne-based, ground-based) measurement campaign in Alberta, Canada. We use empirically derived emission estimates to characterize site-level emissions and derive an emissions distribution. Our work shows that many major sources of emissions are unmeasured or underreported. Consistent with previous studies in the US, a small fraction of sites disproportionately account for the majority of emissions: roughly 20% of sites accounted for 75% of emissions. An independent airborne-based regional estimate was 40% lower than the ground-based regional estimate, but not statistically different. Finally, we summarize next steps as part of the CCAC Oil and Gas Methane Study: ongoing work that is targeting oil and gas sectors/production regions with limited empirical data on methane emissions. This work builds on the approach deployed in quantifying methane emissions from the oil and gas supply chain in the US, underscoring the commitment to transparency of the collected data, external review, deployment of multiple methodologies, and publication of results in peer-reviewed journals.

Do structural oil-market shocks affect stock prices?

International Nuclear Information System (INIS)

Apergis, Nicholas; Miller, Stephen M.

2009-01-01

This paper investigates how explicit structural shocks that characterize the endogenous character of oil price changes affect stock-market returns in a sample of eight countries - Australia, Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. For each country, the analysis proceeds in two steps. First, modifying the procedure of Kilian [Not All Oil Price Shocks are Alike: Disentangling Demand and Supply Shocks in the Crude Oil Market. American Economic Review.], we employ a vector error-correction or vector autoregressive model to decompose oil-price changes into three components: oil-supply shocks, global aggregate-demand shocks, and global oil-demand shocks. The last component relates to specific idiosyncratic features of the oil market, such as changes in the precautionary demand concerning the uncertainty about the availability of future oil supplies. Second, recovering the oil-supply shocks, global aggregate-demand shocks, and global oil-demand shocks from the first analysis, we then employ a vector autoregressive model to determine the effects of these structural shocks on the stock market returns in our sample of eight countries. We find that international stock market returns do not respond in a large way to oil market shocks. That is, the significant effects that exist prove small in magnitude. (author)

Leung, Guy C.K.

2010-01-01

Over the past two decades, China's oil demand has risen steeply. In 1990, it was only about 25% higher than that of 1978, the year economic reform was introduced. By 2008, it had reached 396.0 million tons, roughly four times the 1978 level, making China the second largest oil user worldwide. The country became a net oil importer in 1993, and between 1993 and 2008, its net import dependency - a yardstick for energy security - soared from 7.5% to 50.0%. China's increased demand for oil has made the country a global energy player of critical importance. Although the literature on the global implications of China's oil use has proliferated, relatively few studies have attempted to examine ''how China uses oil.'' Hence, this study covers every oil-consuming facility and sector in China, exploring the patterns of, and factors involved in, oil demand by power plants, oil refineries, heat plants and, gas-works, and industrial, transport, agricultural, household and commercial sectors. It concludes that in virtually all sectors in China, oil demand will grow, with transport and industry leading the way. (author)

Economic Exposure to Oil Price Shocks and the Fragility of Oil-Exporting Countries

Toon Vandyck

2018-04-01

Full Text Available From a price range between 100 and 120 USD (U.S. dollars per barrel in 2011–2014, the crude oil price fell from mid-2014 onwards, reaching a level of 26 USD per barrel in January 2016. Here we assess the economic consequences of this strong decrease in the oil price. A retrospective analysis based on data of the past 25 years sheds light on the vulnerability of oil-producing regions to the oil price volatility. Gross domestic product (GDP and government revenues in many Gulf countries exhibit a strong dependence on oil, while more diversified economies improve resilience to oil price shocks. The lack of a sovereign wealth fund, in combination with limited oil reserves, makes parts of Sub-Saharan Africa particularly vulnerable to sustained periods of low oil prices. Next, we estimate the macroeconomic impacts of a 60% oil price drop for all regions in the world. A numerical simulation yields a global GDP increase of roughly 1% and illustrates how the regional impact on GDP relates to oil export dependence. Finally, we reflect on the broader implications (such as migration flows of macroeconomic responses to oil prices and look ahead to the challenge of structural change in a world committed to limiting global warming.

Financialisation, oil and the Great Recession

2015-01-01

This article addresses the role of world oil price hike of 2007–08 in serving to transform the financial and banking crisis into what is commonly referred to the Great Recession. Existing literature on the global crisis of 2007–09 tends to view it as a financial or banking phenomenon, with analyses focusing mainly on state policies, governance mechanisms and market dynamics in transforming the banking crisis of 2007–08 into the economic recession of 2008-12/13 Although often attributing the global meltdown to wider phenomenon of financialisation, rarely do existing perspectives delve into the role of the commodity sector in the global credit crunch. In this paper, we aim to fill this gap, by inquiring into the role played by oil as a financial asset class in the political economy of the global crisis. - Highlights: • We study the oil price and its effects on the Great Recession. • We approach oil as a financial asset class. • We observe the transformation of oil through deregulation.

Global oil risks in the early 21st century

Fantazzini, Dean; Höök, Mikael; Angelantoni, André

2011-01-01

The Deepwater Horizon incident demonstrated that most of the oil left is deep offshore or in other difficult to reach locations. Moreover, obtaining the oil remaining in currently producing reservoirs requires additional equipment and technology that comes at a higher price in both capital and energy. In this regard, the physical limitations on producing the ever-increasing quantities of oil are highlighted as well as the possibility of the peak of production occurring this decade. The economics of oil supply and demand are also briefly discussed showing why the available supply is basically fixed in the short to medium term. Also, an alarm bell for economic recessions is shown to be when energy takes a disproportionate amount of total consumer expenditures. In this context, risk mitigation practices in government and business are called for. As for the former, early education of the citizenry of the risk of economic contraction is a prudent policy to minimize potential future social discord. As for the latter, all business operations should be examined with the aim of building in resilience and preparing for a scenario in which capital and energy are much more expensive than in the business-as-usual one. - Highlights: ► Review of the physical background to peak oil and current oil situation. ► Economics of oil supply and demand are examined to identify imminent challenges. ► Investigation of the financial and energy transition risks associated with peak oil. ► Oil scarcity and price volatility induce certain governmental and business risks. ► General risk mitigation is vital and peak oil preparations should be undertaken.

Energy Return on Investment (EROI) for Forty Global Oilfields Using a Detailed Engineering-Based Model of Oil Production

2015-01-01

Studies of the energy return on investment (EROI) for oil production generally rely on aggregated statistics for large regions or countries. In order to better understand the drivers of the energy productivity of oil production, we use a novel approach that applies a detailed field-level engineering model of oil and gas production to estimate energy requirements of drilling, producing, processing, and transporting crude oil. We examine 40 global oilfields, utilizing detailed data for each field from hundreds of technical and scientific data sources. Resulting net energy return (NER) ratios for studied oil fields range from ≈2 to ≈100 MJ crude oil produced per MJ of total fuels consumed. External energy return (EER) ratios, which compare energy produced to energy consumed from external sources, exceed 1000:1 for fields that are largely self-sufficient. The lowest energy returns are found to come from thermally-enhanced oil recovery technologies. Results are generally insensitive to reasonable ranges of assumptions explored in sensitivity analysis. Fields with very large associated gas production are sensitive to assumptions about surface fluids processing due to the shifts in energy consumed under different gas treatment configurations. This model does not currently include energy invested in building oilfield capital equipment (e.g., drilling rigs), nor does it include other indirect energy uses such as labor or services.

Oil Dependence, Climate Change and Energy Security: Will Constraints on Oil Shape our Climate Future or Vice Versa?

Science.gov (United States)

Mignone, B. K.

2008-12-01

Threats to US and global energy security take several forms. First, the overwhelming dependence on oil in the transport sector leaves the US economy (and others) vulnerable to supply shocks and price volatility. Secondly, the global dependence on oil inflates prices and enhances the transfer of wealth to authoritarian regimes. Finally, the global reliance on fossil fuels more generally jeopardizes the stability of the climate system. These three threats - economic, strategic and environmental - can only be mitigated through a gradual substitution away from fossil fuels (both coal and oil) on a global scale. Such large-scale substitution could occur in response to potential resource constraints or in response to coordinated government policies in which these externalities are explicitly internalized. Here, I make use of a well-known integrated assessment model (MERGE) to examine both possibilities. When resource limits are considered alone, global fuel use tends to shift toward even more carbon-intensive resources, like oil shale or liquids derived from coal. On the other hand, when explicit carbon constraints are imposed, the fuel sector response is more complex. Generally, less stringent climate targets can be satisfied entirely through reductions in global coal consumption, while more stringent targets require simultaneous reductions in both coal and oil consumption. Taken together, these model results suggest that resource constraints alone will only exacerbate the climate problem, while a subset of policy-driven carbon constraints may yield tangible security benefits (in the form of reduced global oil consumption) in addition to the intended environmental outcome.

2016-04-01

The globalization and regionalization of crude oil trade inevitably give rise to the difference of crude oil prices. The understanding of the pattern of the crude oil prices' mutual propagation is essential for analyzing the development of global oil trade. Previous research has focused mainly on the fuzzy long- or short-term one-to-one propagation of bivariate oil prices, generally ignoring various patterns of periodical multivariate propagation. This study presents a wavelet-based network approach to help uncover the multipath propagation of multivariable crude oil prices in a joint time-frequency period. The weekly oil spot prices of the OPEC member states from June 1999 to March 2011 are adopted as the sample data. First, we used wavelet analysis to find different subseries based on an optimal decomposing scale to describe the periodical feature of the original oil price time series. Second, a complex network model was constructed based on an optimal threshold selection to describe the structural feature of multivariable oil prices. Third, Bayesian network analysis (BNA) was conducted to find the probability causal relationship based on periodical structural features to describe the various patterns of periodical multivariable propagation. Finally, the significance of the leading and intermediary oil prices is discussed. These findings are beneficial for the implementation of periodical target-oriented pricing policies and investment strategies.

Full Text Available Vetiver oil (Vetiveria zizanoides has been used as perfume materials, cosmetics, fragrance soaps, anti-inflammation, repellent, and insecticidal agents. Organic vetiver oil has higher economical value than non-organic vetiver oil and it has been regarded to be able to compete in the global market. Therefore, studies have been carried out using 1 hectare of land and the first generation of organic vetiver oil has produced 0.57% of yield, greater than non-organic (0.50%. The quality of organic and non-organic vetiver oil was analyzed by Indonesian Standard (SNI parameter, pesticide residue test, chemical composition by GC/MS, and the appearance of vetiver root. In general, the result of organic and non-organic vetiver oil has fulfilled the national standard; the quality of organic vetiver oil was better than non-organic one. Physically, the appearance of organic vetiver root was better than non-organic vetiver root; organic vetiver root was denser, more appealing, and did not have any black spots. The pesticide residue of organic vetiver oil was lower than non-organic vetiver oil. Based on SNI test, vetiverol (oxygen compounds in organic vetiver oil was higher than non-organic vetiver oil.

Full Text Available This article analyzes the influence of the economic sanctions imposed from the USA and the EU and oil prices reduction on the oil and gas companies and the directions of diversification of their activity as a method of management of price risks are considered. In the modern dynamic and quickly developing world, in the conditions of globalization and market economy, the oil and gas companies are affected by various risks which can exert negative impact on production and financial results. Risks can arise in absolutely various spheres, beginning from natural and technological hazards, and finishing with price risks. Sharp reduction of oil prices and decrease in demand for energy resources in the world markets, first of all in the European countries, input of financial or technological sanctions from the USA and Europe against Russia in 2014 has caused necessity of search a new more effective methods of price risks management of the oil and gas company. The methods of price risk management include the creation of commodity reserves, the establishment of a reserve fund, long-term contracts, subsidies from the state and the diversification of activities. The most effective it is possible to offer diversification of oil and gas companies' activity. It is expedient to carry out diversification of oil and gas companies' activity in such directions as geographical diversification of the oil, oil products and gas realization directions, geographical diversification of oil and gas companies' purchasing activity, diversification of oil, oil products and gas transportation ways, diversification of oil and gas companies' business. This approach allows to expand the activities of the oil and gas companies and create additional ways to generate revenue and enhance efficiency of oil and gas companies.

Access to high-grade micronutrients is a recurring challenge that often threatens the long-term sustainability of food fortification programs. To assess the efficiency of the Global Alliance for Improved Nutrition (GAIN) Premix Facility in procuring quality, affordable vitamin A for fortification of edible oil in Indonesia. A global approach to procurement of standard items was used by combining volumes across various demand streams in order to reduce the total cost of acquisition through economies of scale. The GAIN Premix Facility undertook a detailed analysis of vitamin A requirements across its existing customer base, which served as a basis for developing a reliable demand forecast. A consolidated, competitive tender was launched that resulted in the setting up of a long-term commercial agreement with the selected supplier to lock in the most competitive price for a given period of time. The direct benefit to oil manufacturers of fortifying with vitamin A is that the cost of fortification went down significantly compared with prices they would have been offered had they ordered vitamin A individually. In Indonesia, this consolidated procurement approach has allowed a 14.5% decrease in the unit price of vitamin A. The GAIN Premix Facility demonstrated its effectiveness in acting as a global procurement platform by aggregating demand across different customers and leveraging improved prices through increased volumes. Building on the success of this effort, the GAIN Premix Facility is replicating this global approach for procurement of other standard items being procured across fortification programs worldwide.

Global models of biophysical suitability for oil palm consistently rank Brazil as having the greatest potential for expansion, with estimates as high as 238 Mha of suitable lands. In 2010, Brazil launched the Sustainable Palm Oil Production Program (SPOPP) to incentivize oil palm development without deforestation on as much as 30 Mha. Here we examine oil palm expansion before and after the SPOPP’s launch. In Pará, the major oil palm producing state in Brazil, we analyze the extent and change in oil palm cultivation from 2006-2014 using satellite imagery, ground-truthed verification, site-based interviews, and rural environmental (land) registration data. Between 2006-2014, oil palm area (≥9 ha) expanded >200% to ~219 000 ha. Of the ~148 000 ha of oil palm developed, ~91% converted pasturelands while ~8% replaced natural vegetation, including intact and secondary forests. Although >80% of all oil palm parcels rest role of agro-ecological suitability mapping among them. Interviews indicated that: (1) individual effects of suitability mapping efforts to encourage oil palm expansion on cleared areas, i.e. without deforestation, cannot be disentangled from pre-existing public and private deforestation reduction initiatives; and, (2) socio-economic constraints, e.g. high relative production costs and limited familiarity with this crop, appear to partially explain the major discrepancy between estimated potential suitable areas with realized oil palm development.

Hamilton identifies 1973 to 1996 as “the age of OPEC” and 1997 to the present as “a new industrial age.” During 1974-1996 growth in non-OPEC oil production Granger causes growth in OPEC oil production. OPEC oil production decreases significantly with positive shocks to non-OPEC oil production in the earlier period, but does not do so in the “new industrial age”. In the “new industrial age” OPEC oil production rises significantly with an increase in oil prices, unlike during “the age of OPEC” ...

Full Text Available Background. It seems that patients may ask general practitioners about natural cosmetics applied on the skin regarding their safety and suitability. Objectives. The aim of the study was to analyze natural cold pressed oils as potential cosmetic products. Material and methods. Cold pressed oils obtained from selected seeds and fruit stones were analyzed, including: chokeberry seed oil, blackcurrant seed oil, elderberry seed oil, raspberry seed oil, apricot seed oil, tomato seed oil, strawberry seed oil, broccoli seed oil, Nigella sativa seed oil, hemp oil, safflower seed oil, Silybum marianum seed oil and coconut oil. 80 adult volunteers assessed the cosmetic properties of the analyzed oils. Each of the volunteers tested 2 to 4 different oils, by applying them on the skin. In addition, patch tests with all analyzed oils were performed on 23 individuals. Results. The majority of tested oils were positively evaluated by the participants: in the opinion of the participants, oil extracted from safflower had the best appearance (100% positive opinions, coconut oil had the best smell (70% positive opinions, while black currant seed oil showed the best absorbency (85% positive opinions. No irritation was observed within the analyzed product group, albeit one allergic reaction to apricot seed oil was observed with patch testing. Conclusions . Based on the achieved results, it could be suggested that natural cold pressed oils can be applied to the skin as cosmetics. Our observations may be helpful for general practitioners when choosing natural cosmetics.

Do oil shocks predict economic policy uncertainty?

Rehman, Mobeen Ur

2018-05-01

Oil price fluctuations have influential role in global economic policies for developed as well as emerging countries. I investigate the role of international oil prices disintegrated into structural (i) oil supply shock, (ii) aggregate demand shock and (iii) oil market specific demand shocks, based on the work of Kilian (2009) using structural VAR framework on economic policies uncertainty of sampled markets. Economic policy uncertainty, due to its non-linear behavior is modeled in a regime switching framework with disintegrated structural oil shocks. Our results highlight that Indian, Spain and Japanese economic policy uncertainty responds to the global oil price shocks, however aggregate demand shocks fail to induce any change. Oil specific demand shocks are significant only for China and India in high volatility state.

This article analyzes general aspects in the development of petrochemistry and carbochemistry on a global scale and for industry in the German Democratic Republic. Diagrams are given for liquid and solid carbon resources and their natural hydrogen content showing the increasing hydrogen demand for chemical fuel conversion processes. The petrochemical and carbochemical industry must take a growing level of hydrogen demand into account, which is at present 25 Mt/a on a global scale and which increases by 7% annually. Various methods for chemical processing of crude oil and crude oil residues are outlined. Advanced coal conversion processes with prospects for future application in the GDR are also explained, including the methanol carbonylation process, which achieves 90% selectivity and which is based on carbon monoxide hydrogenation, further the Transcat process, using ethane for vinyl chloride production. Acetylene and carbide carbochemistry in the GDR is a further major line in research and development. Technological processes for the pyrolysis of vacuum gas oil are also evaluated. (27 refs.)

Oil and entrepreneurship

Majbouri, Mahdi

2016-01-01

Economic theory predicts that rents produced from natural resources, especially oil and gas, can increase opportunities for entrepreneurship, but they may also reduce engagement in entrepreneurial activities as they change incentives towards rent-seeking. Using Global Entrepreneurship Monitor (GEM) annual surveys, this study provides empirical evidence that more per capita profit from oil and gas reduces entrepreneurship only in corrupt environments. The more the corruption is, the larger is the impact. The results have important implications for policy makers, especially in resource rich developing countries. - Highlights: •Profits from oil and gas have positive and negative impacts on entrepreneurship. •This study explains these impacts and provides empirical evidence on them. •It uses Global Entrepreneurship Monitor and WB Subsoil and Forest rents datasets. •It employs a dynamic panel data estimation with country fixed effects. •It shows that the negative impact dominates as corruption and oil and gas rents increase.

Peak oil demand: the role of fuel efficiency and alternative fuels in a global oil production decline.

Science.gov (United States)

Brandt, Adam R; Millard-Ball, Adam; Ganser, Matthew; Gorelick, Steven M

2013-07-16

Some argue that peak conventional oil production is imminent due to physical resource scarcity. We examine the alternative possibility of reduced oil use due to improved efficiency and oil substitution. Our model uses historical relationships to project future demand for (a) transport services, (b) all liquid fuels, and (c) substitution with alternative energy carriers, including electricity. Results show great increases in passenger and freight transport activity, but less reliance on oil. Demand for liquids inputs to refineries declines significantly after 2070. By 2100 transport energy demand rises >1000% in Asia, while flattening in North America (+23%) and Europe (-20%). Conventional oil demand declines after 2035, and cumulative oil production is 1900 Gbbl from 2010 to 2100 (close to the U.S. Geological Survey median estimate of remaining oil, which only includes projected discoveries through 2025). These results suggest that effort is better spent to determine and influence the trajectory of oil substitution and efficiency improvement rather than to focus on oil resource scarcity. The results also imply that policy makers should not rely on liquid fossil fuel scarcity to constrain damage from climate change. However, there is an unpredictable range of emissions impacts depending on which mix of substitutes for conventional oil gains dominance-oil sands, electricity, coal-to-liquids, or others.

The world energy demand in 2007: How high oil prices impact the global energy demand? June 9, 2008

International Nuclear Information System (INIS)

2008-01-01

How high oil prices impact the global energy demand? The growth of energy demand continued to accelerate in 2007 despite soaring prices, to reach 2,8 % (+ 0,3 point compared to 2006). This evolution results from two diverging trends: a shrink in energy consumption in most of OECD countries, except North America, and a strong increase in emerging countries. Within the OECD, two contrasting trends can be reported, that compensate each other partially: the reduction of energy consumption in Japan (-0.8%) and in Europe (-1.2%), particularly significant in the EU-15 (-1.9%); the increase of energy consumption in North America (+2%). Globally, the OECD overall consumption continued to increase slightly (+0.5%), while electricity increased faster (2,1%) and fuels remained stable. Elsewhere, the strong energy demand growth remained very dynamic (+5% for the total demand, 8% for electricity only), driven by China (+7.3%). The world oil demand increased by 1% only, but the demand has focused even more on captive end usages, transports and petrochemistry. The world gasoline and diesel demand increased by around 5,7% in 2007, and represents 53% of the total oil products demand in 2007 (51% in 2006). If gasoline and diesel consumption remained quasi-stable within OECD countries, the growth has been extremely strong in the emerging countries, despite booming oil prices. There are mainly two factors explaining this evolution where both oil demand and oil prices increased: Weak elasticity-prices to the demand in transport and petrochemistry sectors Disconnection of domestic fuel prices in major emerging countries (China, India, Latin America) compared to world oil market prices Another striking point is that world crude oil and condensate production remained almost stable in 2007, hence the entire demand growth was supported by destocking. During the same period, the OPEC production decreased by 1%, mainly due to the production decrease in Saudi Arabia, that is probably more

Full Text Available The global sustained low oil prices have a significant impact on China's oil and gas industry system and the national energy security. This paper aims to find solutions in order to guarantee the smooth development of China's oil and gas industry system and its survival in such a severe environment. First, the origins of sustained low oil prices were analyzed. Then, based on those published data from IEA, government and some other authorities, this study focused on the development status, energy policies and the future developing trend of those main oil & gas producing countries. Investigations show that the low-price running is primarily contributed to the so-called oil and gas policies in the USA. It is predicted that national petroleum consumption will reach up to 6.0 × 108 t (oil & 3300 × 108 m3 (gas in 2020 and 6.8 × 108 t (oil & 5200 × 108 m3 (gas in 2030. For reducing the dependence on foreign oil and gas, the investment in the upstream of oil and gas industry should be maintained and scientific research should be intensified to ensure the smooth operation of the oil and gas production system. Considering China's national energy security strategy, the following suggestions were proposed herein. First, ensure that in China the yearly oil output reaches 2 × 108 t, while natural gas yield will be expected to be up to 2700 × 108 m3 in 2030, both of which should become the “bottom line” in the long term. Second, focus on the planning of upstream business with insistence on risk exploration investment, scientific and technological innovation and pilot area construction especially for low-permeability tight oil & gas, shale oil & gas reservoir development techniques. Third, encourage the in-depth reform and further growth especially in the three major state-owned oil & gas companies under adverse situations, and create more companies competent to offer overseas technical services by taking the opportunity of the �

Global production through 2005

Two companion studies released recently should provide great food for thought among geo-political strategists and various national governments. If predictions contained in these Petroconsultants studies of oil and gas production trends for the next 10 years are realized, there will be great repercussions for net exporters and importers, alike. After analyzing and predicting trends within each of the world's significant producing nations for the 1996--2005 period, the crude oil and condensate report concludes tat global production will jump nearly 24%. By contrast, worldwide gas output will leap 40%. The cast of characters among producers and exporters that will benefit from these increases varies considerably for each fuel. On the oil side, Russia and the OPEC members, particularly the Persian Gulf nations, will be back in the driver's seat in terms of affecting export and pricing patterns. On the gas side, the leading producers will be an interesting mix of mostly non-OPEC countries. The reemergence of Persian Gulf oil producers, coupled with an anticipated long-term decline among top non-OPEC producing nations should present a sobering picture to government planners within large net importers, such as the US. They are likely to find themselves in much the same supply trap as was experienced in the 1970s, only this time the dependence on foreign oil supplies will be much worse. Gas supplies will not be similarly constrained, and some substitution for oil is probable. Here, two articles, ''World oil industry is set for transition'' and ''Worldwide gas surges forward in next decade,'' present a summary of the findings detailed in Petroconsultants' recent studies

Improved oilfield GHG accounting using a global oilfield database

Roberts, S.; Brandt, A. R.; Masnadi, M.

2016-12-01

The definition of oil is shifting in considerable ways. Conventional oil resources are declining as oil sands, heavy oils, and others emerge. Technological advances mean that these unconventional hydrocarbons are now viable resources. Meanwhile, scientific evidence is mounting that climate change is occurring. The oil sector is responsible for 35% of global greenhouse gas (GHG) emissions, but the climate impacts of these new unconventional oils are not well understood. As such, the Oil Climate Index (OCI) project has been an international effort to evaluate the total life-cycle environmental GHG emissions of different oil fields globally. Over the course of the first and second phases of the project, 30 and 75 global oil fields have been investigated, respectively. The 75 fields account for about 25% of global oil production. For the third phase of the project, it is aimed to expand the OCI to contain closing to 100% of global oil production; leading to the analysis of 8000 fields. To accomplish this, a robust database system is required to handle and manipulate the data. Therefore, the integration of the data into the computer science language SQL (Structured Query Language) was performed. The implementation of SQL allows users to process the data more efficiently than would be possible by using the previously established program (Microsoft Excel). Next, a graphic user interface (gui) was implemented, in the computer science language of C#, in order to make the data interactive; enabling people to update the database without prior knowledge of SQL being necessary.

Concerns over the sustained availability of fossil fuels and their impact on global warming and pollution have led to the search for fuels from renewable sources to address worldwide rising energy demands. Biodiesel is emerging as one of the possible solutions for the transport sector. It shows comparable engine performance to that of conventional diesel fuel, while reducing greenhouse gas emissions. However, the toxicity of products and effluents from the biodiesel industry has not yet been sufficiently investigated. Brazil has a very high potential as a biodiesel producer, in view of its climatic conditions and vast areas for cropland, with consequent environmental risks because of possible accidental biodiesel spillages into water bodies and runoff to coastal areas. This research determined the toxicity to two marine organisms of the water-soluble fractions (WSF) of three different biodiesel fuels obtained by methanol transesterification of castor oil (CO), palm oil (PO), and waste cooking oil (WCO). Microalgae and sea urchins were used as the test organisms, respectively, for culture-growth-inhibition and early-life-stage-toxicity tests. The toxicity levels of the analyzed biodiesel WSF showed the highest toxicity for the CO, followed by WCO and the PO. Methanol was the most prominent contaminant; concentrations increased over time in WSF samples stored up to 120 d. Copyright © 2010 SETAC.

The World Oil Industry (WOI) developed through two types of economic organization, built up around vertically integrated and internationalized enterprises: the US model, based on private international firms, and the model centered on setting up State-run enterprises, initially in the United Kingdom, Argentina and Mexico. However, from the first oil crisis (1973) onwards, the World Oil Industry has gradually been un-bundled through nationalization and the loss of control over the reserves by the oil majors. With this new configuration of the industry, from the 1980's onwards, the strategies of the major international oil companies focused on developing the spot market, while lowering investment and operating costs, introducing correlated diversification strategies, and enhancing industrial concentration through mergers and acquisitions and/or cooperation agreements between companies. The core purpose of these strategic shifts is to obtain control over new oil field areas. The restructuring processes of national oil industries all over the world - particularly in South America - constituted an important drive aligned with these new guidelines, headed up by the global oil operators. This paper analyzes the changes in the South American oil sector during the 1990's, analyzing aspects involved in awarding mineral rights in the upstream segment. Despite similar policies, market deregulation processes follow different patterns. However, the most significant aspect is an increase in the presence of international private capital in the dynamics of this sector, mainly in regional energy integration processes. (authors)

The existence of a clear globalization trend is recognized inside the oil industry, but with a persisting specificity coming from the access conditions to the oil deposits. (author)

EVOLUTIONS IN GLOBAL AUTOMOBILES INDUSTRY

Full Text Available This paper is a brief overview of the evolution of the global automotive industry during the 20th century, with reference to the main manufacturers, oil crises of 1970-1980, and also the global financial and economic crisis that began in 2008. The analyzed period covers the rise of the Asian Continent, beginning with Japan, then South Korea and more recently the emerging countries: China and India. What was predicted 20-25 years ago, became reality: Asia becomes the economic centre of the world, surpassing unexpectedly fast even the Euro-Atlantic area. Regarding Romania, the revival delay of the automobiles industry, led to the loss of the trucks and bus industry, and after a much awaited rehabilitation of car production, this has stuck now at an unsatisfactory level.

The tug-of-war between resource depletion and technological change in the global oil industry 1981-2009

Energy Technology Data Exchange (ETDEWEB)

Lindholt, Lars

2013-01-15

We perform an empirical analysis of the extent to which ongoing technological change through RandD activity has offset the effect of ongoing depletion on the cost of finding additional reserves of oil in eight global regions. We introduce a finding cost function that among other factors depends on the cumulative number of past RandD expenses and cumulative past production, measuring technological change and depletion, respectively. For all our regions we find significant effects of both depletion and technological change on oil finding costs from 1981 to 2009, barring cyclical variations in finding costs that could come from changes in factor prices. For almost all regions technology more than mitigated depletion until around the mid-nineties. However, we find that depletion outweighed technological progress over the last decade.(author)

Global Warming Mitigation through the Local Action of Environmental Education in the Plantation Area of Palm Oil

Full Text Available Oil palm is a strategic mainstay product with a crucial role in the national economy, and it can also be carbon sink to mitigate the negative impact of global warming when managed in environmentally friendly manner. Therefore, management and surrounding community need to have an understanding of the environment, and pro-environmental attitude and behaviour. Action research, which aimed at mitigating global warming through the local action of environmental education (EE, was conducted toward oil palm plantation employee and surrounding community. The EE programme was expected to be able to shape understanding and pro-environmental attitude and behaviour in the target group.  Rapid observation and interview were carried out in collecting data for EE programme development.  A needs assessment was conducted in developing the EE subject; based on local environmental problems and gap of target group’s perception of the problems.  Global warming-related environmental problems found in the location included air temperature increase, drought and difficulty in determining planting season.  Spatial analysis based on 1989 and 2014 satellite imagery showed a decrease of the water body, tree vegetated land and open areas, and an increase in non-tree vegetated land and built land, accompanied by an increase in areas with higher temperature range.  Both employees and the community had a good knowledge of the environment, but less in conservation. The environmental education provided for them had been able to increase their perception on environmental conservation. However, repetition and intensive assistance are still needed to strengthen the perception

Oil shale commercialization study

Energy Technology Data Exchange (ETDEWEB)

Warner, M.M.

1981-09-01

Ninety four possible oil shale sections in southern Idaho were located and chemically analyzed. Sixty-two of these shales show good promise of possible oil and probable gas potential. Sixty of the potential oil and gas shales represent the Succor Creek Formation of Miocene age in southwestern Idaho. Two of the shales represent Cretaceous formations in eastern Idaho, which should be further investigated to determine their realistic value and areal extent. Samples of the older Mesozonic and paleozoic sections show promise but have not been chemically analyzed and will need greater attention to determine their potential. Geothermal resources are of high potential in Idaho and are important to oil shale prospects. Geothermal conditions raise the geothermal gradient and act as maturing agents to oil shale. They also might be used in the retorting and refining processes. Oil shales at the surface, which appear to have good oil or gas potential should have much higher potential at depth where the geothermal gradient is high. Samples from deep petroleum exploration wells indicate that the succor Creek shales have undergone considerable maturation with depth of burial and should produce gas and possibly oil. Most of Idaho's shales that have been analyzed have a greater potential for gas than for oil but some oil potential is indicated. The Miocene shales of the Succor Creek Formation should be considered as gas and possibly oil source material for the future when technology has been perfectes. 11 refs.

Do Oil-Producing Countries Have Normal Oil Overconsumption? An Investigation of Economic Growth and Energy Subsidies

Directory of Open Access Journals (Sweden)

Seyed Reza Mirnezami

2015-07-01

Full Text Available The data shows that oil-producing countries have low oil retail prices and low economic growth compared with other countries. Considering that oil-producing countries experience high oil consumption and low economic growth, it is possible to argue that economic growth is not an appropriate justification for oil consumption and that the main cause for high oil consumption is the low retail price. In addition, it should be noted that the global environmental movement against increasing greenhouse gas emissions—for example, the Kyoto 1998 agreement—seems to have had no effect on oil consumption in oil-producing countries.

Parker, Cindy L.; Kirschenmann, Frederick L.; Tinch, Jennifer; Lawrence, Robert S.

2011-01-01

Peak oil is the phenomenon whereby global oil supplies will peak, then decline, with extraction growing increasingly costly. Today's globalized industrial food system depends on oil for fueling farm machinery, producing pesticides, and transporting goods. Biofuels production links oil prices to food prices. We examined food system vulnerability to rising oil prices and the public health consequences. In the short term, high food prices harm food security and equity. Over time, high prices will force the entire food system to adapt. Strong preparation and advance investment may mitigate the extent of dislocation and hunger. Certain social and policy changes could smooth adaptation; public health has an essential role in promoting a proactive, smart, and equitable transition that increases resilience and enables adequate food for all.

The evolution of oil refining in Europe

Energy Technology Data Exchange (ETDEWEB)

Reid, A. [CONCAWE, Brussels (Belgium)

2013-04-01

Back in 1963 when CONCAWE was founded, the world looked very different from what it is today, and so did the global and European refining industry. Oil product markets were expanding fast and new refineries were being built at a steady rate. The oil crisis of the 1970s brought an abrupt end to this, heralding a long era of consolidation and stepwise adaptation. At the same time the nature of the global oil business shifted from fully integrated companies producing, transporting and refining their own oil to a much more diversified situation where oil production ('upstream') and refining/distribution ('downstream') gradually became two essentially separate businesses. From being purely a 'cost centre' in an integrated chain, refining has become a separate activity in its own right, operating as a 'profit centre' between two global markets - crude oil and products - which, although not entirely independent, have their own dynamics and influences. In addition demand gradually shifted towards lighter products while the quality requirements on all products were considerably tightened. This article explores the new challenges that these changes have imposed on EU refiners, and describes CONCAWE's contributions to understanding their impact on refinery production and investments.

Medium-Term Oil Market Report 2006

2006-07-01

How much oil will the world consume in 2011? What role will OPEC play in global oil production? Will biofuels become an important part of the oil market? The International Energy Agencys (IEA) Medium-Term Oil Market Report tackles these questions, adopting a perspective that goes beyond the traditional short-term market analysis provided in the IEAs monthly Oil Market Report. Drawing on current futures curves and the investment threshold for upstream projects, the Medium-Term Oil Market Report analyses how global demand and supply balances may develop in the next five years. The forecasts look in detail at product demand and the supply potential from all the firmly planned individual upstream and downstream projects around the world. The results provide invaluable insights on vital issues such as surplus production capacity and product supply. The rapid pace of change in the oil market means that forecasts can become outdated very quickly. This interim update provides the opportunity to rebase the data and forecasts in the annual Medium-Term Oil Market Report and to discuss and analyse new issues affecting the oil industry. Policymakers, market analysts, energy experts and anyone interested in understanding and following trends in the oil market should find this report extremely useful.

The dominant theme in the world energy market was the fall in oil prices in 2014. From 115 US-$/bbl in June it dropped to below 50 US-$/bbl in January 2015. Thereby the shale oil revolution has had the strong impact on the global energy situation, to this point has been predicted for three years. Although no one could predict the exact height of the fall in oil prices, but with oil as a reserve currency for all other fuels, it has not only had an impact on the gas and coal prices, but other commodities, such as copper, have also yielded. About cause and effect, there is a lot of speculation - not all of which are supported by wisdom. [de

2012-01-01

The role of crude oil as the main energy source for the global economic activity has motivated the discussion about the dynamics and causes of crude oil price changes. An accurate understanding of the issue should provide important guidelines for the design of optimal policies and government budget planning. Using daily data for WTI over the period January 1986–March 2011, we analyze the evolution of the informational complexity and efficiency for the crude oil market through multiscale entropy analysis. The results indicated that the crude oil market is informationally efficient over the scrutinized period except for two periods that correspond to the early 1990s and late 2000s US recessions. Overall, the results showed that deregulation has improved the operation of the market in the sense of making returns less predictable. On the other hand, there is some evidence that the probability of having a severe US economic recession increases as the informational efficiency decreases, which indicates that returns from crude oil markets are less uncertain during economic downturns. - Highlights: ► Entropy concepts are used to characterize crude oil prices. ► An index of market efficiency is introduced. ► Except for periods of economic recession, the crude oil market is informationally efficient.

New business models for state companies in the oil industry

2016-09-01

Full Text Available In the scientific literature business models are defined as architecture of the value creation, profit formula, key processes and key resources. For the oil industry there is a need to develop new business models that have to describe the specificity of this industry and to take into consideration the new objectives after the global oil crisis. Although crude oil price has dropped dramatically since second quarter 2014, OPEC raised crude output to the its highest value in more than three years as it pressed on with a strategy to protect market share and pressure competing producers. The objective of this article is to identify and promote new business models for state companies in the oil industry. The research methodology is based on case studies that present and analyze the business models in two of the main oil producers Iran and Iraq, where the state companies are playing an important role in this industry. The subject is relevant because the business models for state companies in the oil industry have to be modified after the oil crisis and these are not real analysed in the scientific literature. Furthermore, the aspects discussed in the current article represent the main factors that will influence investment prospects of companies in the field in the next decade.

GLOBAL PROSPECTS OF SYNTHETIC DIESEL FUEL PRODUCED FROM HYDROCARBON RESOURCES IN OIL&GAS EXPORTING COUNTRIES

Directory of Open Access Journals (Sweden)

2007-12-01

Full Text Available Production of synthetic diesel fuel through Fischer-Tropsch process is a well known technology which dates from II World War, when Germany was producing transport fuel from coal. This process has been further improved in the South Africa due to period of international isolation. Today, with high crude oil market cost and increased demand of energy from China and India, as well as global ecological awareness and need to improve air quality in urban surroundings, many projects are being planned regarding production of synthetic diesel fuel, known as GTL (Gas To Liquid. Most of the future GTL plants are planned in oil exporting countries, such are Qatar and Nigeria, where natural gas as by-product of oil production is being flared, losing in that way precious energy and profit. In that way, otherwise flared natural gas, will be transformed into synthetic diesel fuel which can be directly used in all modern diesel engines. Furthermore, fossil fuel transportation and distribution technology grid can be used without any significant changes. According to lower emissions of harmful gasses during combustion than fossil diesel, this fuel could in the future play a significant part of EU efforts to reach 23% of alternative fuel share till 2020., which are now mostly relied on biodiesel, LPG (liquefied petroleum gas and CNG (compressed natural gas.

Compositional modification of crude oil during oil recovery

2003-05-01

Ten crude oils from two recovery stages spanning 5-10-year interval of five productive wells in the Tarim Basin, northwest China were analyzed for their compositional modification during production process. Significant compositional changes in polar and nonpolar fractions between the previous oil samples and the latter ones were noted at both bulk and molecular level. The latter oil samples appear to contain more aromatic fraction and less asphaltenes and resin, and their gas chromatography (GC) data for whole oil show reduced alkanes with low molecular weight and enhanced high homologue relative to the previous oil samples. Compared with the oils collected from the previous recovery stage, the concentration of basic type of nitrogen-containing compounds and organic acids in oils from the latter recovery stage have a reducing trend, suggesting the occurrence of interaction between crude oil and reservoir rock.

Cost-effectiveness criteria for marine oil spill preventive measures

Vanem, Erik; Endresen, Oyvind; Skjong, Rolf

2008-01-01

Oil tanker accidents resulting in large quantities of oil spills and severe pollution have occurred in the past, leading to major public attention and an international focus on finding solutions for minimising the risks related to such events. This paper proposes a novel approach for evaluating measures for prevention and control of marine oil spills, based on considerations of oil spill risk and cost effectiveness. A cost model that incorporates all costs of a shipping accident has been established and oil tanker spill accidents have been further elaborated as a special case of such accidents. Utilising this model, novel implementation criteria, in terms of the Cost of Averting a Tonne of oil Spilt (CATS), for risk control options aiming at mitigating the environmental risk of accidental oil spills, are proposed. The paper presents a review of previous studies on the costs associated with oil spills from shipping, which is a function of many factors such as location of spill, spill amount, type of oil, etc. However, ships are designed for global trade, transporting different oil qualities. Therefore, globally applicable criteria must average over most of these factors, and the spill amount is the remaining factor that will be used to measure cost effectiveness against. A weighted, global average cleanup cost of USD 16,000/tonne of oil spilt has been calculated, considering the distribution of oil tanker traffic densities. Finally, the criteria are compared with some existing regulations for oil spill prevention, response and compensation (OPA 90)

Reducing US Oil Dependence Using Simulation

People across the world are addicted to oil; as a result, the instability of oil prices and the shortage of oil reserves have influenced human behaviors and global businesses. Today, the United States makes up only 5% of the global population but consumes 25% of the. world total energy. Most of this energy is generated from fossil fuels in the form of electricity. The contribution of this paper is to examine the possibilities of replacing fossil fuel with renewable energies to generate electricity as well as to examine other methods to reduce oil and gas consumption. We propose a system dynamics model in an attempt to predict the future US dependence on fossil fuels by using renewable energy resources such as, nuclear, wind, solar, and hydro powers. Based on the findings of our model, the study expects to provide insights towards promising solutions of the oil dependency problem.

Quantitative effects of the shale oil revolution

The aim of this paper is to analyze the impact of the so-called “shale oil revolution” on oil prices and economic growth. We employ a general equilibrium model of the world oil market in which Saudi Arabia is the dominant firm, with the rest of the producers as a competitive fringe. Our results suggest that most of the expected increase in US oil supply due to the shale oil revolution has already been incorporated into prices and that it will produce an additional increase of 0.2% in the GDP of oil importers in the period 2010–2018. We also employ the model to analyze the collapse in oil prices in the second half of 2014 and conclude that it was mainly due to positive unanticipated supply shocks. - Highlights: • We analyze the impact of the “shale oil revolution” on oil prices and economic growth. • We employ a general equilibrium model of the oil market in which Saudi Arabia is the dominant firm. • We find that most of the shale oil revolution is already priced in. • We also analyze the decline in oil prices in the second half of 2014. • We find that unanticipated supply shocks played the major role in the fall.

Will oil palm's homecoming spell doom for Africa's great apes?

Expansion of oil palm plantations has led to extensive wildlife habitat conversion in Southeast Asia [1]. This expansion is driven by a global demand for palm oil for products ranging from foods to detergents [2], and more recently for biofuels [3]. The negative impacts of oil palm development on biodiversity [1, 4, 5], and on orangutans (Pongo spp.) in particular, have been well documented [6, 7] and publicized [8, 9]. Although the oil palm is of African origin, Africa's production historically lags behind that of Southeast Asia. Recently, significant investments have been made that will likely drive the expansion of Africa's oil palm industry [10]. There is concern that this will lead to biodiversity losses similar to those in Southeast Asia. Here, we analyze the potential impact of oil palm development on Africa's great apes. Current great ape distribution in Africa substantially overlaps with current oil palm concessions (by 58.7%) and areas suitable for oil palm production (by 42.3%). More importantly, 39.9% of the distribution of great ape species on unprotected lands overlaps with suitable oil palm areas. There is an urgent need to develop guidelines for the expansion of oil palm in Africa to minimize the negative effects on apes and other wildlife. There is also a need for research to support land use decisions to reconcile economic development, great ape conservation, and avoiding carbon emissions. Copyright © 2014 Elsevier Ltd.

Oil and resource-backed aggression

International Nuclear Information System (INIS)

Colgan, Jeff

2011-01-01

A common misperception about oil politics is that it has a uniform, monolithic effect on policy development. This paper argues that in fact the net political effect of oil varies dramatically depending on the nature of the petrostate. It shows that oil income, when combined with revolutionary governments in petrostates, generates strong incentives for foreign policy aggression and international conflict. The aggressiveness of petro-revolutionary states is shown to have consequences in both military and economic spheres of international relations. Militarily, the aggressiveness of this type of state leads to a high rate of armed conflicts. Economically, the aggressiveness of petro-revolutionary states shapes global oil markets and international economic relations. The argument is tested using statistical analysis of international conflicts and economic sanctions. The policy implications are then considered, focusing on the negative global impacts of dependence on oil consumption. - Research highlights: → A radical reconsideration of the link between oil and international conflict is needed. → Resource-backed aggression, not resource-competition, is the major source of conflict. → Petro-revolutionary states instigate 250% more military conflicts than typical states. → Petro-revolutionary states are also more frequently targeted for economic sanctions.

The fluctuations in oil prices are very complicated and therefore, it is unable to predict its effects on economies. For modelling complex system of oil prices, linear economic models are not sufficient and efficient tools. Thus, in recent years, economists attached great attention to non-linear structure of oil prices. For analyzing this relationship, GARCH types of models were used in some papers. Distinctively from the other papers, in this study, we aimed to analyze chaotic pattern of oil prices. Thus, it was used the Lyapunov Exponents and Hennon Map to determine chaotic behavior of oil prices for the selected time period.

Full Text Available Throughout history the new technologies and discoveries revolutionized the way we live. The discovery, the oil, has been critical for society, becoming the world’s most profitable and essential industry transforming itself from domestic to international business. The aim of this paper, above all is to analyze the role of oil and its price volatility in world economy. The ongoing changes and transformations in world oil industry tend to have a great effect not only on the oilimporting countries but also on oil-exporting nations. The demand or supply-triggered oil price volatility differ in its effects to world economic activity. Although it may have different effect for the oil importing nations in comparison to oil exporting nations, still inflationary pressure may be a common feature. A number of points relevant to the study are put forward highlighting pros and cons of issues discussed. The paper also elaborates the environmental concerns, deriving from the increase of oil consumption and the necessity (globally to increase efforts in finding a decent,(environmentally friendly replacement for oil.

The plan of this paper is to review the role of the US in the evolution of international energy security in the past; to examine the present situation and outlook for international energy trade and investment on which the US, and most major consuming countries depend, and, finally, to speculate about the possible effect on energy security of the war against terrorism. It seems that, the slogans of past energy security are not a good guide to the present problems. All industrial countries depend to some extent on imported energy supplies, but have the capacity to pay for imports over a wide range of price scenarios. Price stability is not to be expected: there will be short term shocks to both buyers and sellers, medium term cycles with leads and lags in adjusting supply capacity to demand, and long term uncertainty about the effects of policies aimed at sustainability and protecting the climate. The diversity and flexibility of international trade and investment offers the best long and medium term security and is most likely to achieve adjustments at lowest cost. Competition between oil and other fuels, and between major oil exporters to secure markets for their oil reserves, will limit the possibilities for cartel behaviour. Short-term disruptions do, however, create problems. These have been managed during the last twenty years by a combination of actual or potential use of strategic stocks by importers and reserve capacity by OPEC exporters, particularly Saudi Arabia. The role of Saudi Arabia cannot be separated from its political relationships within the Middle East and with the US. The immense flexibility of policy which the US now enjoys as a superpower could be eroded by a weakening of the acceptance the US receives from governments in the Middle East. In the last resort, if the international system fails, the US and Europe could survive the termination of oil imports from the Middle East; Asia could not, and the consequences for the world economy including

The conference was divided into 8 sessions entitled: (1) oil prices, (2) oil and politics, (3) global oil supply, (4) North American supply and markets, (5) global oil demand, (6) oil.com, (7) the business of the environment, and (8) oil and money. The outlook of world energy markets was reviewed with particular emphasis on prospects for oil supply and reserves. The current status of the petroleum industry in both OPEC and non-OPEC oil exporting countries was discussed with reference to exploration, production, reserves, and hydrocarbon potential. The environmental, and socio-economic challenges that both the upstream and downstream industry will face challenges in the next century were also described. refs., tabs., figs

Oil price shocks and economy: an open question

International Nuclear Information System (INIS)

Di Marzio, G.

2006-01-01

During the 1970s and 1980s advanced oil importing economies faced the adverse effects of oil supply disruptions with abrupt energy price rise, followed by sensible business cycle inversions and stagflation. The negative effects of the sharp energy price increase were amplified by factors such the induced costly resources reallocation between labour and capital, and between sectors of activity; rising uncertainty discouraging investments, and income redistribution consequences on aggregate demands After a shock the economic system generally adjusts in favour of less energy intensive industries; this leads pauses in production as part of the existing capital stock become obsolete, and causes resources under utilization. Since the 1970s a number of economists have been sceptical about why even large price shocks in a resource that accounts for less than 3-4 pct. of global GDP could cause losses of magnitude as those experienced in most advanced economies. They believe that monetary policy has played a role in generating the observed negative correlation between oil prices and economic activity, and question whether the post-oil-shock recessions were attributable to the oil price shocks themselves or to the monetary policy responding to these shocks. Empirical research largely shows a primary responsibility of large price shocks and major oil-supply disruptions on recessionary movements of GDP. Energy prices have risen sharply since 2003, driven by strengthening global demand; market fundamentals suggest that a considerable fraction of recent hikes will be permanent and current price levels remain credible. With limited spare capacity, the medium term oil supply-demand balance is expected to remain tight, and the price probably near current levels. Today' s high oil prices reflect the effects of sustained energy demand trends and, jointly, oil industry under investment during and after the low price era of the 1990s.

This paper presents the microbial ecology of methanogenic crude oil biodegradation. Biodegraded petroleum reservoirs are one of the most dramatic indications of the deep biosphere. It is estimated that heavy oil and oil sands will account for a considerable amount of energy production in the future. Carbon, a major resource for deep subsurface microorganisms, and energy are contained in large quantities in petroleum reservoirs. The aerobic to anaerobic paradigm shift is explained. A key process for in-situ oil biodegradation in petroleum reservoirs is methanogenesis. New paradigms for in-reservoir crude oil biodegradation are discussed. Variations in anaerobic degradation of crude oil hydrocarbons are also discussed. A graph shows the different patterns of crude oil biodegradation under sulfate-reducing and methanogenic conditions. Alternative anaerobic alkane activation mechanisms are also shown. From the study, it can be concluded that methanogenic crude oil degradation is of global importance and led to the establishment of the world's enormous heavy oil deposits.

Global oil and gas trade is increasing, in an environment of rising prices, higher costs, greater environmental concerns, and growing security uncertainties. While predictions of shortages through depletion of oil and gas reserves are unfounded, the world must adapt to higher prices and changing trade patterns, as conventional reserves are increasingly being replaced un-conventional resources. Canada, drawing upon its vast natural resources and technological innovation, is positioned to be an even more important global energy leader in the 21st century. (author)

Techniques for Analyzing the Attractiveness of International Commodity Markets Under Conditions of Economic Globalization

Directory of Open Access Journals (Sweden)

Olha Pryhara

2006-03-01

Full Text Available This article examines existing techniques and proposes its own for analyzing the attractiveness of international commodity markets in light of the globalization of world economic processes. Taking into account the supranational nature of the world economic environment when examining categories in the attractiveness of international commodity markets, the author introduces a multilevel system of indicators: market attractiveness at the mega-level – global level; market attractiveness at the macro-level national level; market attractiveness at the mezo-level – level of an individual sector. The attractiveness of international commodity markets is considered to be the degree of conformity between market environment factors and the mega-, macro- and mezo-levels of the economic interests of enterprises concerning the entry into and strategies for their activity on the international commodity markets in the short-, medium- and long-term. The author designs a stage-by-stage technique for strategically analyzing the attractiveness of international commodity markets in order to frame efficient market strategies of enterprises. Relying on the proposed techniques, she rates the integrated indicators of market accessibility and the possibility of realizing the economic interests of enterprises in target markets, bringing the index data into a matrix of «market accessibility – opportunity for realizing the economic interests of enterprises.» The analysis of a country’s position in the matrix makes it possible to frame efficient market strategies for enterprises.

The outlook for the world and Australian oil markets

International Nuclear Information System (INIS)

Donaldson, K.; Fok, G.

1996-01-01

Global demand for oil is projected to continue its upward trend to 2000-1, with growth in the transport sector expected to underpin future increases in oil consumption. World oil consumption is projected to be matched by global production, keeping the average annual oil price relatively stable. In many countries, the diversion of oil revenue to other projects is threatening to constrain increases in production capacity, particularly in the OPEC countries. The encouragement of foreign investment in state oil industries is a likely method of easing the constraint. Australian exploration activity is rising steadily with the prospect of stable oil prices, expanding gas markets and the incentives provided by a number of recent discoveries. While the geographical pattern of Australian production has now changed, with Western Australian production exceeding Victoria production, Australia is expected to maintain its position in the world oil market as a significant producer, importer and exporter.

Quantification of rice bran oil in oil blends

Energy Technology Data Exchange (ETDEWEB)

Mishra, R.; Sharma, H. K.; Sengar, G.

2012-11-01

Blends consisting of physically refined rice bran oil (PRBO): sunflower oil (SnF) and PRBO: safflower oil (SAF) in different proportions were analyzed for various physicochemical parameters. The quantification of pure rice bran oil in the blended oils was carried out using different methods including gas chromatographic, HPLC, ultrasonic velocity and methods based on physico-chemical parameters. The physicochemical parameters such as ultrasonic velocity, relative association and acoustic impedance at 2 MHz, iodine value, palmitic acid content and oryzanol content reflected significant changes with increased proportions of PRBO in the blended oils. These parameters were selected as dependent parameters and % PRBO proportion was selected as independent parameters. The study revealed that regression equations based on the oryzanol content, palmitic acid composition, ultrasonic velocity, relative association, acoustic impedance, and iodine value can be used for the quantification of rice bran oil in blended oils. The rice bran oil can easily be quantified in the blended oils based on the oryzanol content by HPLC even at a 1% level. The palmitic acid content in blended oils can also be used as an indicator to quantify rice bran oil at or above the 20% level in blended oils whereas the method based on ultrasonic velocity, acoustic impedance and relative association showed initial promise in the quantification of rice bran oil.

2014-05-01

Full Text Available World deepwater is famous for its rich oil and gas reserves, and has become an important source of global oil and gas supply, with a rising investment which will be over the shallow water counterparts in the next few years, as well as an expansion of oil and gas output. The ‘Deepwater Golden Triangle’ of the North American Gulf of Mexico, Brazil and West Africa has been leading the most exploration, development and investment activities in the world, and their experience on fiscal system during different development stages has great reference value other than advanced technologies. Under the assumptions of uncertain oil price and producing cost, this paper analyzed China fiscal system for deepwater oil and gas development, modeled the free natural resource tax, uplifting the threshold of special oil levy, and other scenarios, and compared their results on contractor’s net presented value, internal return rate and present index. Based on net present value, internal return rate, profitability index, as well as the domestic fiscal policies, this paper found that Special Oil Levy levied only on profit oil and the cancel of government share oil would have the most significant incentives, while lower the income tax rate to 15%, raising the threshold price at which the Special Oil Levy payable by 15 $/bbl and zero Value-added tax have much higher feasibility.

Planning Oil Prices In The World Market And Preventive Policies In Energy Sector Of Iran

International Nuclear Information System (INIS)

Raees Dana, Fariborz

1999-01-01

The planning of oil prices in the world can not be analyzed by means of the market-competition theory or the game theory. The current prices seem to be influenced greatly by large energy consuming industries of developed countries, oil producing corporations and cartels, and oil productions outside of OPEC. There is a lack of necessary long term policies and planning so that drastic changes in market prices can be avoided. The goal of this paper is to suggest new policies by means of discussing in following issues: 1.Initiating some form of a financial support for OPEC with the necessary follow up. 2. Utilization of oil income in sectors organized to have the least susceptibility against income loss and the lowest impact on other sectors. 3. Reducing of oil production level in the local and global framework and starting in industrialization process. 4. Replacement of oil with natural gas at a faster rate. 5. improving the oil industry infrastructure for lowering production costs and increasing variety in products in light of country economic policies and occupational strategies. 6. Imposing self-reliance on development of oil-production technology

Glass vs. Plastic: Life Cycle Assessment of Extra-Virgin Olive Oil Bottles across Global Supply Chains

Riccardo Accorsi

2015-03-01

Full Text Available The environmental impacts of global food supply chains are growing with the need for their measurement and management. This paper explores the operations of a global supply chain for extra-virgin olive oil (EVOO according to a life cycle assessment (LCA methodology. The LCA assessment methodology is applied to determine the environmental impact categories associated with the bottled EVOO life cycle, focusing on packaging decisions. The proposed analysis identifies the greatest environmental stressors of the EVOO supply chain, thereby supporting strategic and operative decisions toward more efficient and environmentally-friendly operations management and packaging choices. This paper quantifies the environmental categories of the impacts of global warming potential, ozone layer depletion, non-renewable energy use, acidification, eutrophication and photochemical smog, for the observed EVOO supply chain, given alternative packaging configurations, i.e., a glass bottle vs. a plastic bottle. The observed system includes the supply of EVOO, the EVOO processing and bottling, the supply of packaging, the distribution of final products to customers, the end-of-life (EOL treatments regarding the management, recycling and the disposal of waste across a global supply chain. The findings from the LCA highlight the potential of PET bottles in reducing the environmental impact of EVOO supply chains and identifies hotspots of discussion for policy-makers, EVOO producers and consumers.

The oil markets: A vision

International Nuclear Information System (INIS)

Miras Salamanca, P.

2007-01-01

Although oil markets show high levels of volatility, governments and institutions are much more concern with the problem of security of supply. Fundamental drivers of these markets vary from global questions (such as the balance between world supply and demand or the geopolitical situation), to national and local issues (regulation, industry structure and the cost chain in a given market). Global factors account for the lions share of the final price. Therefore, price variations of oil products tend to be similar in different environment. However, regulators and competition watchdogs should put special attention to supervise smaller areas, where specific problems could occur. (Author)

The three papers of this document were written in the framework of a seminar organized the 30 may 2002 by the IFRI in the framework of its program Energy and Climatic Change. The first presentation deals with the american oil policy since 1980 (relation between the oil dependence and the energy security, the Reagan oil policy, the new oil policy facing the increase of the dependence). The second one deals with the US energy security (oil security, domestic energy security, policy implications). The last presentation is devoted to the US oil dependence in a global context and the problems and policies of international energy security. (A.L.B.)

Reliable in the long run? Petroleum policy and long-term oil supplier reliability

Toft, Peter; Duero, Arash

2011-01-01

Accelerating oil import dependence in energy consuming nations highlights the importance of having energy supplies at sufficient levels and at stable and reasonable prices. Consequently, it is crucial that oil exporters realize their full production potential. Current debates on energy security are often focused on short-term risks e.g. sudden disruptions due to wars, domestic instability, etc. However, when it comes to assessing oil supplier reliability it is equally important to assess their longer term ability and willingness to deliver oil to the global market. This study analyzes the effects of petroleum investment policies on crude oil production trends in 14 major oil producing countries (2000-2010) by focusing on the political-institutional frameworks that shape the investment conditions for the upstream oil sector. Our findings indicate that countries with less favorable oil sector frameworks systematically performed worse than countries with investor friendly and privatized sectors. The findings indicate that assessments based on remaining reserves and planned production capacities alone could inflate expectations about future oil supplies in a world where remaining crude reserves are located in countries with unfavorable investment frameworks. - Highlights: → We explore if policies favoring state-ownership in upstream oil undermine output expectations. → We compare petroleum policies of 14 major oil producers vis-a-vis production trends 2000-2010. → We find major differences between countries favorable to state-owned or private investors. → Substantial private investment seems needed for oil production to meet long-term demand growth.

Implications of globalization on pricing for Canadian crudes

Energy Technology Data Exchange (ETDEWEB)

Black, R. [Canadian Occidental Petroleum Ltd., Calgary, AB (Canada)

1998-05-01

The effects of globalization on Canadian crude oil prices was discussed. Since deregulation in October 1985, Canadian crude oil has competed directly against international crude oil through the use of the NYMEX contract price for light sweet crude oil as the base for establishing the price for Canadian crudes. Prior to that date, Alberta crude was marketed by the Alberta Petroleum Marketing Commission using the old block matrix which was loosely tied to the world market price. In addition to world crude oil prices other factors that affect the price of Canadian crude oil include technology impacts and global integration. Also, when the Sarnia to Montreal pipeline (Line 9) is reversed to bring offshore crude oil into the Ontario refining community, Canadian producers can expect some adverse effects on the price they are paid for their products leading up to the reversal as refiners start to swing over to their alternate suppliers. The offshore supply is expected to be about 140,000 barrels/day of light sweet crude oil, but all grades of Canadian crude oil will be affected.

Strategic Sourcing is a procurement management technique that aims to establish a globally competitive supply base. By setting an appropriate sourcing strategy to specific sourcing groups considering the purchasing volume and the sourcing complexity, significant savings can be achieved in the total company expenditures. There are four basic sourcing strategies that can be used: purchasing process simplification, purchasing volume leverage, strategic relationship with suppliers, supply assurance. E-procurement is a valuable tool for Strategic Sourcing implementation and can be used to simplify and reduce the cost of the purchasing process. Strategic Sourcing can be applied in most industries, as well as in Oil and Gas Industry. Recently Arthur Andersen was engaged in a Strategic Sourcing project for an Oil and Gas Company resulting in savings of 10% cost reduction on the expenditures analyzed. (author)

Towards sustained high oil prices and increasingly volatile

It is particularly difficult to predict the evolution of global oil production and its ability to meet the demand: the main uncertainties are related to the magnitude of the growth of emerging countries, more or less rapid decline in the production of major oil fields current events as well as natural or accidental, but especially geopolitics, which may affect, at any time, production. In a tight market today, the rapid growth of emerging economies, disruption of the oil supply chain world, even its mere mention, could cause short-term loss of excess production capacity - largely concentrated in Saudi Arabia - an increase substantial progress and, as contemplated by the International Atomic Energy imbalances between global oil supply and demand. If, after 2020, production of conventional oil begins to decline and the demand from emerging markets continues to grow, more massive imbalances may arise, leading to potential geopolitical tensions. Control would then demand the best answer. Otherwise, the resources of unconventional hydrocarbons, considerable expected to meet the demand, provided that their development is fast enough and their operating conditions are environmentally friendly. A consensus is emerging today on keeping oil prices high (above $ 100 / barrel) and volatile in the coming years, allowing some producing countries to pursue their development, but for France amplifying the negative effects on the economic growth oil bill (more than 49 billion euros in 2011) weighs more heavily in our trade deficit. In all cases, climate issues, the weight of the oil bill on our economy, securing our energy supply and technical uncertainties or geopolitical oil production call for reducing our oil consumption, accelerated motion the transition to a low carbon economy and development of our own energy resources.

Oil transformation sector modelling: price interactions

International Nuclear Information System (INIS)

Maurer, A.

1992-01-01

A global oil and oil product prices evolution model is proposed that covers the transformation sector incidence and the final user price establishment together with price interactions between gaseous and liquid hydrocarbons. High disparities among oil product prices in the various consumer zones (North America, Western Europe, Japan) are well described and compared with the low differences between oil supply prices in these zones. Final user price fluctuations are shown to be induced by transformation differences and competition; natural gas market is also modelled

Fueling Global Fishing Fleets

Tyedmers, Peter H.; Watson, Reg; Pauly, Daniel

Over the course of the 20th century, fossil fuels became the dominant energy input to most of the world's fisheries. Although various analyses have quantified fuel inputs to individual fisheries, to date, no attempt has been made to quantify the global scale and to map the distribution of fuel consumed by fisheries. By integrating data representing more than 250 fisheries from around the world with spatially resolved catch statistics for 2000, we calculate that globally, fisheries burned almost 50 billion L of fuel in the process of landing just over 80 million t of marine fish and invertebrates for an average rate of 620 L/t. Consequently, fisheries account for about 1.2% of global oil consumption, an amount equivalent to that burned by the Netherlands, the 18th-ranked oil consuming country globally, and directly emit more than 130 million t of CO 2 into the atmosphere. From an efficiency perspective, the energy content of the fuel burned by global fisheries is 12.5 times greater than the edible protein energy content of the resulting catch

Productivity assessment of Angola's oil blocks

This paper analyzes the change in productivity as a result of Angola oil policy from 2001 to 2007. Angola oil blocks are the main source of tax receipts and, therefore, strategically important for public finances. A Malmquist index with the input technological bias is applied to measure productivity change. Oil blocks on average became both more efficient and experienced technological progress. Our results indicate that the traditional growth accounting method, which assumes Hicks neutral technological change, is not appropriate for analyzing changes in productivity for Angola oil blocks. Policy implications are derived. (author)

Peak Oil and other threatening peaks-Chimeras without substance

International Nuclear Information System (INIS)

Radetzki, Marian

2010-01-01

The Peak Oil movement has widely spread its message about an impending peak in global oil production, caused by an inadequate resource base. On closer scrutiny, the underlying analysis is inconsistent, void of a theoretical foundation and without support in empirical observations. Global oil resources are huge and expanding, and pose no threat to continuing output growth within an extended time horizon. In contrast, temporary or prolonged supply crunches are indeed plausible, even likely, on account of growing resource nationalism denying access to efficient exploitation of the existing resource wealth.

Natural Variation of Volatile Compounds in Virgin Olive Oil Analyzed by HS-SPME/GC-MS-FID

Directory of Open Access Journals (Sweden)

Carlos Sanz

2018-04-01

Full Text Available Virgin olive oil is unique among plant oils for its high levels of oleic acid, and the presence of a wide range of minor components, which are responsible for both its health-promoting properties and characteristic aroma, and only produced when olives are crushed during the industrial process used for oil production. The genetic variability of the major volatile compounds comprising the oil aroma was studied in a representative sample of olive cultivars from the World Olive Germplasm Collection (IFAPA, Cordoba, Spain, by means of the headspace solid-phase microextraction/gas chromatography–mass spectrometry–flame ionization detection (HS-SPME/GC-MS-FID. The analytical data demonstrated that a high variability is found for the content of volatile compounds in olive species, and that most of the volatile compounds found in the oils were synthesized by the enzymes included in the so-called lipoxygenase pathway. Multivariate analysis allowed the identification of cultivars that are particularly interesting, in terms of volatile composition and presumed organoleptic quality, which can be used both to identify old olive cultivars that give rise to oils with a high organoleptic quality, and in parent selection for olive breeding programs.

Research and development expenditures by Exxon Corporation, one of the major multi-national oil companies, was studied in an effort to demonstrate the manner in which research and development is planned, managed and financed on a global scale, and to discern the role played in the worldwide network of Exxon Corporation laboratories by Exxon's main Canadian affiliate, Imperial Oil Limited of Sarnia. The findings are based upon close examination of all public documents regarding Exxon and its affiliates since 1882 to 1975, and interviews with research personnel. It was described how in the 1920s, the Sarnia research centre of Imperial Oil began to develop its expertise in lubricant research, earning a world research mandate in 1967 with exclusive rights in this area for the entire Exxon Corporation. It is evident that by being able to concentrate in areas that took advantage of their technological competence and expertise while, on the other hand, ensuring that the processes and products generated by the whole network of laboratories were available and adapted to the Canadian context, the commercial impact of Imperial's research and development efforts have been greatly enhanced by its affiliation with the large multinational company. 27 refs

Assessment of Global Emissions, Local Emissions and Immissions of Different Heating Systems

Georg Erdmann

2009-08-01

Full Text Available This paper assesses and compares existing and new technologies for space heating in Germany (e.g., heat pumps, and solar thermal and wood pellet systems in terms of their environmental impacts. The various technologies were analyzed within the context of the new German legislation. The assessment was carried out on three levels: 1. Global emissions: a life cycle assessment was carried out in order to find the global environmental footprint of the various technologies; 2. Local emissions: the effects of local emissions on human health were analyzed; and 3. Immissions: the immissions were evaluated for the various technologies using a dispersion calculation. A special feature of this study is the substitution of frequently used database emission values by values obtained from field studies and our own measurements. The results show large differences between the different technologies: while electric heat pumps performed quite well in most categories, wood pellet systems performed the best with respect to climate change. The latter, however, are associated with high impacts in other environmental impact categories and on a local scale. The promotion of some technologies (especially systems based on fuel oil, a mixture of fuel oil and rapeseed oil, or a mixture of natural gas and biomethane by the newly introduced German legislation is doubtful. In terms of the immissions of wood pellet systems, it can be concluded that, even for extremely unfavorable meteorological conditions, the regulatory limits are not exceeded and the heating systems have a negligible influence on the total PM load in the ambient air.

After three years of crisis, oil companies are now strongly reinvesting, while oil prices are stabilizing at a reasonable long-term level, notably due to a rising demand from developing countries. Examples of new investments made by majors such as Total, Shell or Exxon but also by national companies and junior companies, are given. Oil price evolution as well as cost reductions (thanks notably to the digitalisation of the sector, leading to a decrease in exploration costs) are analyzed. The importance of the US oil production, and particularly shale oil production, is pinpointed

Clearing up whether spilled oil is mixed or not can strengthen the accuracy of oil spill identification. In the present study, the biomarkers in spilled oil samples were detected. The weathering modes of different types of diagnostic ratio and carbon isotope values of individual n-alkanes were also analyzed. The results showed that the diagnostic ratios of steroids, terpenes and aromatics, and weathering characteristics of carbon isotope composition (δ 13 C) of individual n-alkanes supported the idea that Dalian oil spill emerged from a single oil source. Furthermore, commonly used diagnostic ratios of n-alkanes indicated that the Dalian oil spill had undergone the oil mixing process. The different identifying outcomes indicate that some kinds of n-alkane-rich substance (such as oil dispersants) were mixed in the Dalian spilled oil and interfered with the routine diagnosis ratios of n-alkanes.

HOW PROPERTIES OF EDIBLE OILS ARE IMPROVED BY ESSENTIAL OILS

Full Text Available The main aim of the present paper is to find out whether the addition of essential oils determines better oxidation stability and positive change of sensory and hedonic perception of edible oils. The oxidation stability of sunflower, corn and grape seed oils was analyzed in the presence of antioxidants in essential oils of rosemary (Rosmarinus officinalis, thyme (Thymus vulgaris and basil (Ocimum basilicum during storage, under conditions of accelerated oxidative processes (4 days, at 60 °C. The total phenolic compounds of these essential oils were determined by the Folin-Ciocalteu method. The DPPH method was used to evaluate the antioxidant capacity of basil, rosemary and thyme essential oils in comparison with known synthetic antioxidant L(+-ascorbic acid. The addition of essential oils to edible oils, the amounts proposed in analyses, determines a favorable influence on their oxidation stability as well as their taste. The influence of addition of essential oils on the taste of edible oils was studied in two products consumed mainly at breakfast, bread and spinach leaves. The results recommend the use of these plant extracts as additives in edible oils rather than synthetic antioxidants.

Synthesis of compact patterns for NMR relaxation decay in intelligent "electronic tongue" for analyzing heavy oil composition

Science.gov (United States)

Lapshenkov, E. M.; Volkov, V. Y.; Kulagin, V. P.

2018-05-01

The article is devoted to the problem of pattern creation of the NMR sensor signal for subsequent recognition by the artificial neural network in the intelligent device "the electronic tongue". The specific problem of removing redundant data from the spin-spin relaxation signal pattern that is used as a source of information in analyzing the composition of oil and petroleum products is considered. The method is proposed that makes it possible to remove redundant data of the relaxation decay pattern but without introducing additional distortion. This method is based on combining some relaxation decay curve intervals that increment below the noise level such that the increment of the combined intervals is above the noise level. In this case, the relaxation decay curve samples that are located inside the combined intervals are removed from the pattern. This method was tested on the heavy-oil NMR signal patterns that were created by using the Carr-Purcell-Meibum-Gill (CPMG) sequence for recording the relaxation process. Parameters of CPMG sequence are: 100 μs - time interval between 180° pulses, 0.4s - duration of measurement. As a result, it was revealed that the proposed method allowed one to reduce the number of samples 15 times (from 4000 to 270), and the maximum detected root mean square error (RMS error) equals 0.00239 (equivalent to signal-to-noise ratio 418).

Public Health and Unconventional Oil and Gas Extraction Including Fracking: Global Lessons from a Scottish Government Review.

Watterson, Andrew; Dinan, William

2018-04-04

Unconventional oil and gas extraction (UOGE) including fracking for shale gas is underway in North America on a large scale, and in Australia and some other countries. It is viewed as a major source of global energy needs by proponents. Critics consider fracking and UOGE an immediate and long-term threat to global, national, and regional public health and climate. Rarely have governments brought together relatively detailed assessments of direct and indirect public health risks associated with fracking and weighed these against potential benefits to inform a national debate on whether to pursue this energy route. The Scottish government has now done so in a wide-ranging consultation underpinned by a variety of reports on unconventional gas extraction including fracking. This paper analyses the Scottish government approach from inception to conclusion, and from procedures to outcomes. The reports commissioned by the Scottish government include a comprehensive review dedicated specifically to public health as well as reports on climate change, economic impacts, transport, geology, and decommissioning. All these reports are relevant to public health, and taken together offer a comprehensive review of existing evidence. The approach is unique globally when compared with UOGE assessments conducted in the USA, Australia, Canada, and England. The review process builds a useful evidence base although it is not without flaws. The process approach, if not the content, offers a framework that may have merits globally.

Comparative effects of dietary corn oil, safflower oil, fish oil and palm oil on metabolism of ethanol and carnitine in the rat.

2002-06-01

This study was launched to determine comparative effects of corn oil (CO), safflower oil (SO), fish oil (FO) and palm oil (PO) on carnitine status and ethanol metabolism in rats. Twenty-four male Sprague-Dawley rats (300 g bw) were randomly divided into four groups (n = 6) and fed a semisynthetic diets containing fat as oils listed above. Blood and 24 hour urine samples were collected before and after dietary treatment and acute ethanol administration. Samples were analyzed for blood-ethanol concentration (BEC) and carnitine species. The diets containing FO and PO retarded ethanol metabolism compared to the diets containing CO and SO. The effect of these dietary fats on carnitine species in plasma and urine was varied before and after dietary treatment and following a single oral ethanol dose. The liver carnitine content was higher in the PO group after dietary and ethanol treatment. It is concluded that attenuation of ethanol clearance was related to unique fatty acid makeup of the oils that in part may be attributed to the composite ratio of saturated to unsaturated fatty acids in the oils.

Why the Nature of Oil Shocks Matters

This article studies the impact of oil shocks on the macro-economy in two ways insofar unexploited in the literature. The analysis is conducted at the global level, and it explicitly accounts for the potentially changing nature of oil shocks. Based on an original world GDP series and a grouping of oil shocks according to their nature, we find that oil supply shocks negatively impact world growth, contrary to oil demand shocks, pro-cyclical in their nature. This result is robust at the national level for the US. Furthermore, endogenous monetary policy is shown to have no counter-cyclical effects in the context of an oil demand shock. (authors)

Resistance of many pathogens to available drugs is a global challenge and is leading to growing interest in natural alternative products. In this study, chemical composition and in vitro antibacterial and antifungal activities of the essential oil from Salvia mirzayanii were investigated. The chemical constituents of essential oil from S mirzayanii were analyzed by gas chromatography-mass spectrometry. The antimicrobial activity was determined by broth microdilution. The main identified compounds were 1,8-cineole (41.2 ± 1.3%), linalool acetate (11.0 ± 0.5%), and α-terpinyl acetate (6.0 ± 0.4%) (mL of essential oil/g of plant material). The MIC 95 were 0.03 to 0.5 µL/mL and 16 to 128 µL/mL for gram-positive and gram-negative bacteria, respectively. These results indicated that Salvia mirzayanii essential oil significantly inhibited the growth of standard and clinically isolated tested yeasts by MIC 50 0.03 to 1 µL/mL. Potent antibacterial and antifungal activities of Salvia mirzayanii essential oil may be considered in future study, particularly against antibiotic-resistant cases.

Petrobarter--the exchange of oil for goods and services without reference to monetary currency--has been a widespread and underappreciated practice among corporations, states, and state agencies over the past half century. Analyzing this practice with reference to anthropological theories of barter adds to our understandings of two significant and intertwined concerns in contemporary social science: (1) the production and reproduction of inequality at various scales, from subnational regions to the international system as a whole, and (2) the generation and fate of mobilizing political imaginaries that challenge the abstracted, universalizing imaginaries so often associated with monetized exchange, especially in capitalist contexts. Barter exchanges featuring oil are, therefore, as analytically significant as the much more commonly studied transactions of oil and money. Ethnographic and historical case studies of petrobarter are drawn from the Perm region of the Russian Urals in the post-Soviet period and the global oil trade in the early Cold War. This view from the perspective of the socialist and postsocialist world, it is argued, provides an instructive counterpoint to the many existing studies of oil and money, both in and beyond anthropology, that are situated in the European-American colonial and postcolonial periphery.

The resilience of the Indian economy to rising oil prices as a validation test for a global energy-environment-economy CGE model

This paper proposes to test the global hybrid computable general equilibrium model IMACLIM-R against macro-economic data. To do so, it compares the modeled and observed responses of the Indian economy to the rise of oil price during the 2003-2006 period. The objective is twofold: first, to disentangle the various mechanisms and policies at play in India's economy response to rising oil prices and, second, to validate our model as a tool capable of reproducing short-run statistical data. With default parametrization, the model predicts a significant decrease in the Indian growth rate that is not observed. However, this discrepancy is corrected if three additional mechanisms identified by the International Monetary Fund are introduced, namely the rise in exports of refined oil products, the imbalance of the trade balance allowed by large capital inflows, and the incomplete pass-through of the oil price increase to Indian customers. This work is a first step toward model validation, and provides interesting insights on the modeling methodology relevant to represent an economy's response to a shock, as well as on how short-term mechanisms - and policy action - can smooth the negative impacts of energy price shocks or climate policies.

Pure extra virgin olive oil (EVOO) is mixed with cheaper edible oils and samples are kept inside clear glass containers, while a 785nm Raman system is used to take measurements as Raman probe is placed against glass container. Several types of oils at various concentrations of adulteration are used. Ratios of peak intensities are used to analyze raw data, which allows for quick, easy, and accurate analysis. While conventional Raman measurements of EVOO may take as long as 2 minutes, all measurements reported here are for integration times of 15s. It is found that adulteration of EVOO with cheaper oils is detectable at concentrations as low as 5% for all oils used in this study.

The study examined whether developmental deficits in reading and numerical skills could be expressed in terms of global factors by reference to the rate and amount (RAM) and difference engine (DEM) models. From a sample of 325 fifth grade children, we identified 5 children with dyslexia, 16 with dyscalculia, 7 with a "mixed pattern," and 49 control children. Children were asked to read aloud words presented individually that varied for frequency and length and to respond (either vocally or manually) to a series of simple number tasks (addition, subtraction, number reading, and number comparisons). Reaction times were measured. Results indicated that the deficit of children with dyscalculia and children with a mixed pattern on numerical tasks could be explained by a single global factor, similarly to the reading deficit shown by children with dyslexia. As predicted by the DEM, increases in task difficulty were accompanied by a corresponding increase in inter-individual variability for both the reading and numerical tasks. These relationships were constant across the four groups of children but differed in terms of slope and intercept on the x -axis, indicating that two different general rules underlie performance in reading and numerical skills. The study shows for the first time that, as previously shown for reading, also numerical performance can be explained with reference to a global factor. The advantage of this approach is that it takes into account the over-additivity effect, i.e., the presence of larger group differences in the case of more difficult conditions over and above the characteristics of the experimental conditions. It is concluded that reference to models such as the RAM and DEM can be useful in delineating the characteristics of the dyscalculic deficit as well as in the description of co-morbid disturbances, as in the case of dyslexia and dyscalculia.

Major oil exporters may profit rather than lose, in a carbon-constrained world

International Nuclear Information System (INIS)

Persson, Tobias A.; Azar, C.; Johansson, D.; Lindgren, K.

2007-01-01

The Organization of Petroleum Exporting Countries (OPEC) claims compensation for losses in expected oil export revenues due to CO 2 mitigation measures in developing countries. These losses are expected for two primary reasons: a reduction in the consumption of oil in importing countries and a reduction in the producer price of oil (taxation in an importing country implies a transfer of rents from producers to consumers). So far, most studies have focused on these two mechanisms and corroborated that revenue losses for OPEC are to be expected. However, there are also mechanisms that may be expected to raise the price of oil products. In a cost-effective regime for dealing with climate change, i.e., a regime in which all or most countries participate and in which the same carbon price is applied on all carbon-emitting activities, the cost of using unconventional oil, or synthetic diesel from coal, will increase even more than the cost of using conventional oil. Given that reserves of conventional oil are expected to dwindle over time, heavy oils and coal to liquids might set the long-run price for liquid fuels, which means that the price of oil would increase beyond the carbon fee; i.e., the rent on conventional oil would increase. We use an energy-economic optimization model to analyze these three mechanisms. We find that the net present value of OPEC revenue from conventional oil increases slightly (at most by 4 percent) with a global CO 2 restriction regime. We also consider conditions under which this result does not hold

Downhole Fluid Analyzer Development

Bill Turner

2006-11-28

A novel fiber optic downhole fluid analyzer has been developed for operation in production wells. This device will allow real-time determination of the oil, gas and water fractions of fluids from different zones in a multizone or multilateral completion environment. The device uses near infrared spectroscopy and induced fluorescence measurement to unambiguously determine the oil, water and gas concentrations at all but the highest water cuts. The only downhole components of the system are the fiber optic cable and windows. All of the active components--light sources, sensors, detection electronics and software--will be located at the surface, and will be able to operate multiple downhole probes. Laboratory testing has demonstrated that the sensor can accurately determine oil, water and gas fractions with a less than 5 percent standard error. Once installed in an intelligent completion, this sensor will give the operating company timely information about the fluids arising from various zones or multilaterals in a complex completion pattern, allowing informed decisions to be made on controlling production. The research and development tasks are discussed along with a market analysis.

Climate-wise choices in a world of oil abundance

Brandt, Adam R.; Masnadi, Mohammad S.; Englander, Jacob G.; Koomey, Jonathan; Gordon, Deborah

2018-04-01

Constrained oil supply has given way to abundance at a time when strong action on climate change is wavering. Recent innovation has pushed US oil production to all-time heights and driven oil prices lower. At the same time, attention to climate policy is wavering due to geopolitical upheaval. Nevertheless, climate-wise choices in the oil sector remain a priority, given oil’s large role in modern economies. Here we use a set of open-source models along with a detailed dataset comprising 75 global crude oils (~25% of global production) to estimate the effects of carbon intensity and oil demand on decadal scale oil-sector emissions. We find that oil resources are abundant relative to all projections of 21st century demand, due to large light-tight oil (LTO) and heavy oil/bitumen (HOB) resources. We then investigate the ‘barrel forward’ emissions from producing, refining, and consuming all products from a barrel of crude. These oil resources have diverse life-cycle-greenhouse gas (LC-GHG) emissions impacts, and median per-barrel emissions for unconventional resources vary significantly. Median HOB life cycle emissions are 1.5 times those of median LTO emissions, exceeding them by 200 kgCO2eq./bbl. We show that reducing oil LC-GHGs is a mitigation opportunity worth 10–50 gigatonnes CO2 eq. cumulatively by 2050. We discuss means to reduce oil sector LC-GHGs. Results point to the need for policymakers to address both oil supply and oil demand when considering options to reduce LC-GHGs.

Palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. About 85% of global palm oil produced is used in food applications. Over the past three decades, research on nutritional benefits of palm oil have demonstrated the nutritional adequacy of palm oil and its products, and have resulted in transitions in the understanding these attributes. Numerous studies have demonstrated that palm oil was similar to unsaturated oils with regards to effects on blood lipids. Palm oil provides a healthy alternative to trans-fatty acid containing hydrogenated fats that have been demonstrated to have serious deleterious effects on health. The similar effects of palm oil on blood lipids, comparable to other vegetable oils could very well be due to the structure of the major triglycerides in palm oil, which has an unsaturated fatty acid in the stereospecific numbers (sn)-2 position of the glycerol backbone. In addition, palm oil is well endowed with a bouquet of phytonutrients beneficial to health, such as tocotrienols, carotenoids, and phytosterols. This review will provide an overview of studies that have established palm oil as a balanced and nutritious oil. PMID:25821404

The present studies are intended to study catalysts that make manufacture of liquid fuel possible through coal liquefying reactions, and establish a liquefied oil analyzing method. The following items are discussed based on the achievements obtained by fiscal 1985: in the studies on coal liquefying catalysts, (1) a study on selectively liquefying catalysts, in which elucidation is made on effects of catalyst carriers on reaction selectivity and life of coal liquefying catalysts, and fundamental data are accumulated toward designing the catalysts with respect to catalyst carriers capable of selective hydrogenating reactions, and to carrying conditions; and (2) a study on solvent properties and reaction conditions. in which Mo-based catalysts are used to perform kinetic discussions on the relationship between the liquefying reaction conditions and compositions of solvents and produced oil to accumulate data for elucidating the action mechanisms of the Mo-based catalysts. In the study of the liquefied oil analyzing method, discussions are carried out on a measuring technology to expand the conventional method for liquefied oil analysis to hard-to-volatilize components. For the light and medium oils, an analyzing method will be established that utilizes effectively the NMR method and the MS method that have been established to date. (NEDO)

Saudi Arabia's oil policy after 1. oil crisis explained with the help of a cartel model

Saudi Arabian oil policy is analyzed by using a cartel model where Saudi Arabia's oil production is a function of oil price and oil production in other OPEC countries. Elasticities for oil production and oil price are estimated covering oil crises and 3 intercrises periods. During all intercrises periods, production elasticity is not significantly different from 1 which, to a considerable extent, shows that the oil production in Saudi Arabia followed that of the other OPEC countries. During oil crisis periods, production elasticities were either significantly negative or not significantly different from zero. In most cases, the price elasticity was not significantly different from zero. (au)

African oil palm has the highest productivity amongst cultivated oleaginous crops. Species can constitute a single crop capable to fulfill the growing global demand for vegetable oils, which is estimated to reach 240 million tons by 2050. Two types of vegetable oil are extracted from the palm fruit on commercial scale. The crude palm oil and kernel palm oil have different fatty acid profiles, which increases versatility of the crop in industrial applications. Plantations of the current varieties have economic life-span around 25-30 years and produce fruits around the year. Thus, predictable annual palm oil supply enables marketing plans and adjustments in line with the economic forecasts. Oil palm cultivation is one of the most profitable land uses in the humid tropics. Oil palm fruits are the richest plant source of pro-vitamin A and vitamin E. Hence, crop both alleviates poverty, and could provide a simple practical solution to eliminate global pro-vitamin A deficiency. Oil palm is a perennial, evergreen tree adapted to cultivation in biodiversity rich equatorial land areas. The growing demand for the palm oil threatens the future of the rain forests and has a large negative impact on biodiversity. Plant science faces three major challenges to make oil palm the key element of building the future sustainable world. The global average yield of 3.5 tons of oil per hectare (t) should be raised to the full yield potential estimated at 11-18t. The tree architecture must be changed to lower labor intensity and improve mechanization of the harvest. Oil composition should be tailored to the evolving needs of the food, oleochemical and fuel industries. The release of the oil palm reference genome sequence in 2013 was the key step toward this goal. The molecular bases of agronomically important traits can be and are beginning to be understood at the single base pair resolution, enabling gene-centered breeding and engineering of this remarkable crop.

The problems of global warming and the unstable price of petroleum oils have led to a race to develop environmentally friendly biofuels, such as palm oil or ethanol derived from corn and sugar cane. Biofuels are a potential replacement for fossil fuel, since they are renewable and environmentally friendly. This paper evaluates the combustion performance and emission characteristics of Refined, Bleached, and Deodorized Palm Oil (RBDPO)/diesel blends B5, B10, B15, B20, and B25 by volume, using an industrial oil burner with and without secondary air. Wall temperature profiles along the combustion chamber axis were measured using a series of thermocouples fitted axially on the combustion chamber wall, and emissions released were measured using a gas analyzer. The results show that RBDPO blend B25 produced the maximum emission reduction of 56.9% of CO, 74.7% of NOx, 68.5% of SO(2), and 77.5% of UHC compared to petroleum diesel, while air staging (secondary air) in most cases reduces the emissions further. However, increasing concentrations of RBDPO in the blends also reduced the energy released from the combustion. The maximum wall temperature reduction was 62.7% for B25 at the exit of the combustion chamber.

Oil producers facing a common challenge

International Nuclear Information System (INIS)

Galal, E.E.

1992-01-01

Among the numerous challenges facing our modern world, perhaps the most urgent and dominant are energy related. From the perspective of developing countries they are, in order of priorities, development, energy security and environment. Oil covers above 38% of the global commercial energy needs and gas about 20%. In some commanding sectors of the economy, like transport, oil is for now virtually the irreplaceable source of energy. In addition, oil and gas are two valuable primary materials of the chemical industry. It also happens that oil consumption is one of the sources of environmental pollution through the emission of CO 2 . Utilisation of the world's finite fossil energy resources (88% of total commercial energy) in the service of development reflects all the negative attributes of the mismanagement of the global economy, exemplified by waste, inefficiency, unfair terms of trade, market instability and short-sighted policies. These serious inequities have been further compounded by the growing menace of environmental and climatic degradation. In dealing with the interactions between these three complex systems, i.e., energy, environment and development, it is important for oil producers to delineate their priorities clearly, if they are to disentangle credible common goals for an international convention.

Highlights: • The whole formation process of shale oil might be divided into four stages. • Higher ash/shale mass ratio intensified the cracking and coking of shale oil. • Ash/shale ratio of 1:2 was recommended for oil shale fluidized bed retort with fine oil-shale ash as solid heat carrier. - Abstract: For exploring and optimizing the oil shale fluidized bed retort with fine oil-shale ash as a solid heat carrier, retorting experiments of oil shale and fine oil-shale ash mixtures were conducted in a lab-scale retorting reactor to investigate the effects of fine oil-shale ash on shale oil. Oil shale samples were obtained from Dachengzi Mine, China, and mixed with fine oil-shale ash in the ash/shale mass ratios of 0:1, 1:4, 1:2, 1:1, 2:1 and 4:1. The experimental retorting temperature was enhanced from room temperature to 520 °C and the average heating rate was 12 °C min −1 . It was found that, with the increase of the oil-shale ash fraction, the shale oil yield first increased and then decreased obviously, whereas the gas yield appeared conversely. Shale oil was analyzed for the elemental analysis, presenting its atomic H/C ratio of 1.78–1.87. Further, extraction and simulated distillation of shale oil were also conducted to explore the quality of shale oil. As a result, the ash/shale mixing mass ratio of 1:2 was recommended only for the consideration of increasing the yield and quality of shale oil

Oil Price Rise and the Great Recession of 2008

Full Text Available The financial crises of 2007-2008, caused wide-spread falling output and unemployment, in the affected countries and also globally. The severity of the recession was such that it was called the “Great Recession”. As a result of an increase in demand from China and India, at the same time, oil prices rose significantly. The empirical results from this study show that oil price changes negatively affected global growth rate in the 1970s but not in the 1990s and 2000s. These results suggest that the Great Recession in 2008 that initiated by the financial crises, was independent of a significant rise in oil prices.

Alberta's oil sands are now at the crossroads of a series of significant and complex global issues that will require careful negotiation by all stakeholders involved in the oil sands industry. This paper discussed methods of managing uncertainty and risk related to the oil sands industry's agenda for the future. Oil sands developers must continue to secure permission from communities and other key stakeholders in order to develop oil sand projects. Stakeholder relations between oil sands operators, First Nations, and Metis Nation communities must ensure that respect is maintained while environmental impacts are minimized and long-term economic benefits are secured for all parties. Environmental non-governmental organizations (ENGOs) must ensure that oil sands resources are developed responsibly, and that environmental standards are maintained. Seven key shifts in stakeholder relations resulting from the recent economic crisis were identified. These included (1) withdrawal from the multi-stakeholder process, (2) increased focus on government to demonstrate policy leadership, (3) a stronger push from ENGOs to express environmental concerns, (4) global lobby and public relations efforts from ENGOs, (5) companies retreating to local community stakeholders, (6) more active demands from First Nations and Metis Nations groups, and (7) companies challenging ENGO campaigns. The study concluded by suggesting that government leadership is needed to clear policy and regulatory frameworks for Canada's oil sands.

The role of the Arctic in future global petroleum supply

This paper aims to examine the dynamic linkages among the gold market, US dollar and crude oil market. The analysis also delves more deeply into the effect of the global financial crisis on the short-term relationship. We use fractional cointegration to analyze the long-term memory feature of these volatility processes to investigate whether they are tied through a common long-term equilibrium. The DCC-MGARCH model is employed to investigate the time-varying long-term linkages among these markets. The Krystou-Labys non-linear asymmetric Granger causality method is used to examine the effect of the financial crisis. We find that (i) there is clearly a long-term dependence among these markets; (ii) the dynamic gold-oil relationship is always positive and the oil-dollar relationship is always negative; and (iii) after the crisis, we can observe evidence of a positive non-linear causal relationship from gold to US dollar and US dollar to crude oil, and a negative non-linear causal relationship from US dollar to gold. Investors who want to construct their optimal portfolios and policymakers who aim to make effective macroeconomic policies should take these findings into account.

Full Text Available Unconventional oil and gas extraction (UOGE including fracking for shale gas is underway in North America on a large scale, and in Australia and some other countries. It is viewed as a major source of global energy needs by proponents. Critics consider fracking and UOGE an immediate and long-term threat to global, national, and regional public health and climate. Rarely have governments brought together relatively detailed assessments of direct and indirect public health risks associated with fracking and weighed these against potential benefits to inform a national debate on whether to pursue this energy route. The Scottish government has now done so in a wide-ranging consultation underpinned by a variety of reports on unconventional gas extraction including fracking. This paper analyses the Scottish government approach from inception to conclusion, and from procedures to outcomes. The reports commissioned by the Scottish government include a comprehensive review dedicated specifically to public health as well as reports on climate change, economic impacts, transport, geology, and decommissioning. All these reports are relevant to public health, and taken together offer a comprehensive review of existing evidence. The approach is unique globally when compared with UOGE assessments conducted in the USA, Australia, Canada, and England. The review process builds a useful evidence base although it is not without flaws. The process approach, if not the content, offers a framework that may have merits globally.

Full Text Available Introduction: Oil pulling as described in ancient Ayurveda involves the use of edible vegetable oils as oral antibacterial agents. It is a practice of swishing oil in the mouth for oral and systemic health benefits. Pure coconut oil has antimicrobial properties and is commonly available in all Indian households. Aim: This study aims to assess the effect of oil pulling therapy with pure coconut oil on Streptococcus mutans count and to compare its efficacy against sesame oil and saline. Materials and Methods: A randomized controlled concurrent parallel- triple blinded clinical trial was conducted. Thirty participants in age range of 20–23 years were randomly allocated into Group A (coconut oil, Group B (sesame oil, and Group C (saline, with 10 in each group. The participants were instructed to swish and pull 10 ml of oil on empty stomach, early morning for 10–15 min. Unstimulated saliva collected before and after oil pulling procedure was analyzed for colony forming units (CFU per ml saliva of S. mutans. The data were analyzed using paired t-test, ANOVA, and post hoc analysis using Tukey's honest significant difference. Statistical significance was set at P < 0.05. Results: A statistically significant reduction in S. mutans CFU count after oil pulling with pure coconut oil (P = 0.001 was found. There was no statistically significant difference between sesame oil and coconut oil (P = 0.97 and between sesame oil and saline (P = 0.061. When efficacy of coconut oil against saline was evaluated, a statistical significant difference (P = 0.039 was found. Conclusion: Oil pulling is an effective method for oral hygiene maintenance as it significantly reduces S. mutans count in the saliva.

Background: Mercury is a global contaminant with toxic, persistent effects on human health. Petroleum extraction is an important source of elemental mercury; little is known about human exposure levels near oil fields in the Amazon basin. Objectives: To characterize mercury levels in people living near oil production sites in the Peruvian and Ecuadorian Amazon, controlling for fish consumption, occupation, source of water and socio-demographic characteristics. Methods: Analyze mercury levels in urine samples using cold vapour atomic fluorescence spectrometry from 76 indigenous men and women in eight riverine communities situated near oil wells or pipelines. Subjects answered a questionnaire soliciting socio-demographic, occupational and dietary information. Data were analyzed using multiple linear regression modeling. Results: The mean value of U-Hg was 2.61 μg/g creatinine (95% CI: 2.14–3.08), with 7% of the sample recording values above the global background standard suggested by The World Health Organization (5 μg/g creatinine). Women who used water from a surface source had two and a half times the amount of mercury in their urine (mean=3.70 μg/g creatinine, 95% CI: 2.26–5.15) compared with women who used other water sources (mean =1.39 μg/g creatinine, 95% CI: 0.51–2.25). Men who were involved in an oil clean-up operation had twice as much mercury in their urine (mean =3.07 μg/g creatinine, 95% CI: 1.97–4.16) as did those who worked on other tasks (mean =1.56 μg/g creatinine, 95% CI: 1.48–2.65). Mercury levels were not associated with the number of fish meals per week. Conclusions: Indigenous peoples of the Peruvian and Ecuadorian Amazon living near oil production sites generally had urine mercury levels within the global background standard suggested by the World Health Organization. Increased levels of mercury in urine were detected for men involved in oil spill remediation and for women who relied on surface water for household needs. These

Oil, migration, and the political economy of HIV/AIDS prevention in Nigeria's Niger Delta.

Udoh, Isidore A

2013-01-01

In most of sub-Saharan Africa, HIV/AIDS is driven by endemic structural problems such as unemployment, poverty, forced migration, sexual exploitation, and concurrent sexual partnerships. In the Niger Delta of Nigeria, the epidemic is exacerbated by recurring regional conflict and negative environmental externalities resulting from 50 years of oil exploration. This article seeks to identify and analyze potential barriers to HIV/AIDS prevention and treatment from oil pollution and other environmental stressors in Nigeria's Niger Delta. We develop a conceptual framework to understand how oil politics and economic systems affect HIV risks in Nigeria. We then evaluate evidence of how environmental exposures can amplify risks. Using 10 semi-structured interviews, with 85 focus group participants, we test the argument that HIV transmission in the Niger Delta is related to a manipulative "divide and rule" power dynamic that characterizes multinational oil companies' role in shaping conflict contours in oil communities. Oil exploration destroys livelihoods, institutions, and values and forces impoverished and illiterate girls and women to migrate or be trafficked to urban centers as child laborers and sex workers. The elevated HIV/AIDS risk in the Niger Delta brings into focus the political economy of resource extraction, globalization, and indigenous, minority rights and struggles.

Value of NMR logging for heavy oil characterization

Non-conventional, heavy oil fields are becoming increasingly important to the security of energy supplies and are becoming economically profitable to produce. Heavy oil reservoirs are difficult to evaluate since they are typically shallow and the connate waters are very fresh. Other heavy oil reservoirs are oil-wet where the resistivities are not indicative of saturation. Nuclear magnetic resonance (NMR) detects molecular level interactions. As such, it responds distinctively to different hydrocarbon molecules, thereby opening a new avenue for constituent analysis. This feature makes NMR a more powerful technique than bulk oil density or viscosity measurements for characterizing oils, and is the basis for detecting gas in heavy oil fields. NMR logging, which measures fluid in pore space directly, is capable of separating oil from water. It is possible to discern movable from bound water by analyzing NMR logs. The oil viscosity can be also quantified from NMR logs, NMR relaxation time and diffusivity estimates. The unique challenges for heavy oil reservoir characterization for the NMR technique were discussed with reference to the extra-fast decay of the NMR signal in response to extra-heavy oil/tars, and the lack of sensitivity in measuring very slow diffusion of heavy oil molecules. This paper presented various methods for analyzing heavy oil reservoirs in different viscosity ranges. Heavy oil fields in Venezuela, Kazakhstan, Canada, Alaska and the Middle East were analyzed using different data interpretation approaches based on the reservoir formation characteristics and the heavy oil type. NMR direct fluid typing was adequate for clean sands and carbonate reservoirs while integrated approaches were used to interpret extra heavy oils and tars. It was concluded that NMR logs can provide quantitative measures for heavy oil saturation, identify sweet spots or tar streaks, and quantify heavy oil viscosity within reasonable accuracy. 14 refs., 16 figs.

Medium-Term Oil Market Report 2013: Market Trends and Projections to 2018

2013-06-01

The global oil market will undergo sweeping changes over the next five years. The 2013 Medium-Term Oil Market Report evaluates the impact of these changes on the global oil system by 2018 based on all that we know today – current expectations of economic growth, existing or announced policies and regulations, commercially proven technologies, field decline rates, investment programmes (upstream, midstream and downstream), etc. The five-year forecast period corresponds to the length of the typical investment cycle and as such is critical to policymakers and market participants. This Report shows, in detailed but concise terms, why the ongoing North American hydrocarbon revolution is a ''game changer''. The region’s expected contribution to supply growth, however impressive, is only part of the story: Crude quality, infrastructure requirements, current regulations, and the potential for replication elsewhere are bound to spark a chain reaction that will leave few links in the global oil supply chain unaffected. While North America is expected to lead medium-term supply growth, the East-of- Suez region is in the lead on the demand side. Non-OECD oil demand, led by Asia and the Middle East, looks set to overtake the OECD for the first time as early as 2Q13 and will widen its lead afterwards. Non-OECD economies are already home to over half global refining capacity. With that share only expected to grow by 2018, the non-OECD region will be firmly entrenched as the world’s largest crude importer. These and other changes are carefully laid out in this Report, which also examines recent and future changes in global oil storage, shifts in OPEC production capacity and crude and product trade, and the consequences of the ongoing refinery construction boom in emerging markets and developing economies. It is required reading for anyone engaged in policy or investment decision-making in the energy sphere, and those more broadly interested in the oil

The relationship between oil and nuclear energy in the global energy scene over the past 50 years is analysed. The former nuclear-oil product competition in power generation and various end-use markets is found to have transformed into a complementary relationship. Current concerns associated with both energy sources and related technologies, including price volatility, supply security, geopolitical sensitivity, depletion alarms, and environmental pollution issues for oil, economic performance, operational safety, proliferation, terrorism, radioactive waste disposal, and the resulting public acceptance for nuclear are examined as determinants of their future roles in the world energy balance. An assessment of the long-term prospects for oil and nuclear energy is presented at the scale of a century to support further economic and energy policy analyses. It is the first in-depth study of global energy projections based on a comparative examination of long-term socio-economic scenarios and their coordinated quantifications by a set of integrated energy-economy models

Improvement of Waste Tire Pyrolysis Oil and Performance Test with Diesel in CI Engine

Full Text Available The standard of living, quality of life, and development of a nation depend on its per capita energy consumption. Global energy supply that mainly depends on fossil fuel is decreasing day by day. It is estimated that the energy demand will be increased five times by the year 2021 from present scenario. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Pyrolysis is one of the promising alternative fuel technologies which produces valuable oil, char, and gas product from organic waste. Early investigations report that tire pyrolysis oil extracted from vacuum pyrolysis method seemed to have properties similar to diesel fuel. The main concern of this paper is to produce and improve the properties of crude tire pyrolysis oil by desulfurizing, distilling, and utilizing it with diesel in CI engine to analyze the efficiency for various compositions.

Full Text Available The main objective of this study is to examine the stock markets’ shock due to the effect of the price of oil in the East Asia Region. Particularly, this study examines if there is stock market interdependence during global oil price shocks (sudden changes for a sample of five total oil importers (the Philippines, Hong Kong SAR, Taiwan, South Korea, and Japan, four net oil importers (Indonesia, Singapore, Thailand, and China, and one net oil exporter (Malaysia between 1999 and 2014. From the result, an oil price change is collectively found to have a small but significant positive impact on the stock markets, in particular where a sudden decrease in oil prices tends to cause a stock market downturn and volatility. The world economy’s spending, financial investments in oil futures and foreign investment by oil rich nations are some underlying motives for inducing this oil-stock positive relation. The same direction of time-varying conditional correlations is found across East Asian stock markets during negative oil price shocks. The integration among East Asian stock markets is inducing the oil shock contagion to be transmitted from direct oil-affected countries (South Korea, Hong Kong, and Singapore to non-direct oil affected countries’ (Japan and Taiwan stock markets. In spite of a long practiced ASEAN+3 macroeconomics surveillance process and Early Warning System (EWS which can be customized for stock markets to prevent or detect the oil risk, hedging against initial oil-affected stock markets and a stronger influence by the East Asian countries in the global world of oil and capital investment are strongly suggested.

Full Text Available Crude oil production industry as the hub of Nigeria Economy is not immune to the global financial meltdown being experienced world over which have resulted in a continual fall of oil price. This has necessitated the need to reduce cost of production. One of the major costs of production is corrosion cost, hence, its evaluation. This research work outlined the basic principles of corrosion prevention, monitoring and inspection and attempted to describe ways in which these measures may be adopted in the context of oil production. A wide range of facilities are used in crude oil production making it difficult to evaluate precisely the extent of corrosion and its cost implication. In this study, cost of corrosion per barrel was determined and the annualized value of corrosion cost was also determined using the principles of engineering economy and results analyzed using descriptive statistics. The results showed that among the corrosion prevention methods identified, the use of chemical treatment gave the highest cost contribution (81% of the total cost of prevention while coating added 19%. Cleaning pigging and cathodic protection gave no cost. The contribution of corrosion maintenance methods are 60% for repairs and 40% for replacement. Also among the corrosion monitoring and inspection identified, NDT gave the highest cost contribution of 41% of the total cost, followed by coating survey (34%. Cathodic protection survey and crude analysis gives the lowest cost contribution of 19% and 6% respectively. Corrosion control cost per barrel was found to be 77 cent/barrel. The significance of this cost was not much due to high price of crude oil in the international market. But the effect of corrosion in crude oil processing takes its toll on crude oil production (i.e. deferment.

Energy globalization

Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

Global Carbon-and-Conservation Models, Global Eco-States? Ecuador’s Yasuní-ITT Initiative and Governance Implications

Directory of Open Access Journals (Sweden)

Conny Davidsen

2013-05-01

Full Text Available The “global carbon age” marks a structural change far beyond the economic realms of implementing carbon trade, affecting the fabric of global environmental governance and its actors. Carbon trade and conservation in the Global South have taken on various forms, and climate change mitigation efforts in light of continued rainforest deforestation are scrambling to establish effective approaches. Ecuador’s Yasuní-ITT Initiative proposes a new global carbon-and-conservation model in the Ecuadorian Amazon that leaves oil reserves of the Yasuní Ishpingo Tambococha Tiputini (ITT oil fields underground, in exchange for international compensation payments that would be based on voluntary contributions of governments and nongovernmental actors in an international conservation partnership and trust fund under the auspices of the United Nations Development Programme. This model suggests far-reaching consequences, as it introduces new global scales for the sharing and management of environmental costs within a framework of neoliberal cost internalization. The analysis in this paper uses the concept of the “ecological state” (Duit, 2008 as a theoretical point of departure to examine the trans-scalar implications of such a carbon-and-conservation model on global governance structures toward a “global ecological state” (or global eco-state.

Ethics and the oil industry

Bauquin, P.R.

In many countries public opinions are more and more sensitive to ethical issues linked to the manner in which industries and particularly oil companies behave. Oil companies are frequently unpopular, among the public both in producing and consuming countries. After a brief analysis of the reasons for this unpopularity, the author attempts to show both the ambiguities surrounding the question of ethics, and its complexity. This is especially true when oil companies have to work in countries which are destabilized, and in which disturbances - or even civil wars - may be fuelled by the important revenue streams resulting from the oil production. The various ethical issues are reviewed, from human rights to political interference, without omitting global or local environmental problems. Despite the very deep roots of the various issues the author believe some progress is achievable and advocates that the oil industry lead the way in this difficult domain. (author)

In this investigation, spectroscopic (FT-IR, UV-Vis, {sup 1}H NMR) and chromatographic (GC) techniques were used to analyze two Jordanian shale oils, Sultani and El-Lajjun. The oils were extracted at different pyrolysis temperatures (400-500{sup o}C) using a fluidized bed reactor. The spectroscopic and chromatographic analyses show that the variation of pyrolysis temperature has no significant effect on the composition of the produced oil. The {sup 1}H NMR results indicate that the protons of methyl and methelyene represent the bulk of the hydrogen ({approx}90%) in most shale oil samples. GC analysis reveals that the oil samples contain n-alkanes with a predominant proportion of n-C{sub 25}. (Author)

Unconventional Liquids, Peak Oil and Climate Change

Hughes, J. D.

Oil is the largest source of primary energy in the world, at 32% of 2014 consumption. Forecasts by the International Energy Agency suggest oil will continue to provide the largest share of global energy through 2040, even with new policies to mitigate greenhouse gas emissions. The IPCC's Representative Concentration Pathway (RCP) scenarios indicate that between 1.5 and 3.8 trillion barrels of oil will be burnt between 2015 and 2100. Various sources suggest that the world has 5 to 6 trillion barrels of remaining recoverable oil, more than half of which are in low grade deposits. Although oil sands and extra heavy oil are claimed to hold 1.5 trillion barrels, assessments of major deposits in the Canadian oil sands and the Venezuela Orinoco Belt, which hold the bulk of these resources, total less than 500 billion barrels of recoverable oil. Kerogen oil (oil shale), which has never been produced in anything but miniscule volumes, comprises an additional trillion barrels of these estimates. These unconventional deposits are very different from the conventional oil of the past as: - they are rate constrained, as they require massive upfront capital investments and lengthy construction periods, and therefore cannot be scaled up quickly in response to declines in conventional production. - they are expensive, both in terms of cost per barrel and the large energy inputs required for production. The best in situ oil sands deposits may yield an energy return of 3:1 and kerogen oil even less if it ever becomes commercially viable. This compares to 10:1 or more for conventional oil. Shale oil (light tight oil), may yield another 300 billion barrels worldwide, but suffers from high decline rates, expensive wells and limited availability of high quality deposits. The most productive and economically viable portions of these unconventional deposits tend to be exploited first, leaving the less productive, higher cost oil for later. As a result, increasing global oil consumption

The role of the Arctic in future global petroleum supply

Lindholt, Lars; Glomsroed, Solveig

2011-07-01

The Arctic has a substantial share of global petroleum resources, but at higher costs than in most other petroleum provinces. Arctic states and petroleum companies are carefully considering the potential for future extraction in the Arctic. This paper studies the oil and gas supply from 6 arctic regions during 2010-2050 along with global economic growth and different assumptions regarding petroleum prices and resource endowments. Supply is calculated based on a global model of oil and gas markets. The data on undiscovered resources for the Arctic is based on the estimates by USGS. Sensitivity studies are carried out for two alternative price scenarios and for a 50 per cent reduction of arctic undiscovered resources compared with the USGS 2008 resource estimate. Although a major part of the undiscovered arctic petroleum resources is natural gas, our results show that the relative importance of the Arctic as a world gas supplier will decline, while its importance as a global oil producer may be maintained. We also show that less than full access to undiscovered oil resources will have minor effect on total arctic oil production and a marginal effect on arctic gas extraction. The reason is that Arctic Russia is an important petroleum producer with a sufficiently large stock of already discovered resources to support their petroleum production before 2050. (Author)

This report focuses on Unilever, which shares major institutional investors with other leading corporations including Nestle, Procter and Gamble and Kraft. Not only do these corporations share investors, they also share growing carbon liability within their raw material supply chains through the expansion in the palm oil sector in Indonesia. Unilever has recognised the global problems associated with palm oil expansion and the need for drastic reform to this sector. Unilever has taken a bold move in calling for an immediate moratorium on deforestation and peatland clearance. While Unilever's position is strengthened by its status as the largest palm oil consumer in the world, this report shows how, unless companies like Nestle, Procter and Gamble and Kraft support its call for a halt to deforestation, the palm oil industry will continue to present a massive carbon liability over the coming years. This report uses Unilever's palm oil supply chains as a case study to help quantify the carbon liability and collateral risks associated with the Indonesian palm oil sector. It shows how, by buying palm oil from suppliers who account for more than one-third of Indonesia's palm oil production, Unilever and its competitors are increasing their potential carbon liability and thus leaving investors exposed to potentially significant levels of hidden risk, compromising long-term financial and brand stability.

Oil fiscal regimes and national oil companies: A comparison between Pemex and Petrobras

2017-01-01

Analysis of the determinants of the performance of national oil companies (NOCs) is and has always been among the most discussed topics in specialized literature. In this context, the uneven path experienced by two major Latin American NOCs – Petrobras and Pemex – is striking. Our work seeks to explain the uneven performance, focusing on the productive aspects. In particular, we analyze the oil fiscal regimes in Brazil and Mexico as a very crucial aspect – though not the only one – within oil-rich countries that may shed light on the disparities between Petrobras and Pemex. The contribution of our work to the existing literature derives from the relationship that we establish between the characteristics of the respective oil fiscal regimes and the productive performance of the two NOCs, with special consideration paid to the ways in which a fiscal regime contributes, or not, to promoting and guiding the investment efforts of companies. We compare investment, production, and reserve indicators of Pemex and Petrobras and conclude that the Mexican and Brazilian oil fiscal regimes can largely explain the productive and investor performance of both NOCs. - Highlights: • We analyze the oil fiscal regimes in Brazil and Mexico. • We outline the major features in both national oil companies, Petrobras and Pemex. • We compare investment, production, and reserve indicators of Pemex and Petrobras. • We conclude that the OFRs largely explain the productive performance of the NOCs.

How equity markets view heavy oil

Janisch, M.L.

2001-01-01

A review of heavy oil economics was presented in this power point presentation with particular focus on investor motivation, the importance of heavy oil, and an outlook on commodity price for oil and natural gas. Heavy oil from oil sands is playing a major role on the Canadian domestic production front as well as globally. Almost all senior Canadian producers have a major heavy oil project in the works. Oil prices are forecasted to remain strong, but a more bullish outlook is expected for natural gas prices for both the short and long term. Natural gas drilling has increased, but the number of natural gas wells as a percentage of total wells has decreased. Recent Canadian drilling activity has placed more emphasis on crude oil production which has contributed to the lower overall natural gas drilling success rate. It was shown that infrastructure issues regarding tankers, refining capacity (at or near capacity) will be the major factor affecting the availability of crude products to market. It was also shown that heavy oil differentials have increased substantially, which could be a potential issue if oil prices begin to weaken. 1 tab., 12 figs

Opening of the cell did not reveal asphaltenes retained due to wall adhesion. Size exclusion chromatography tests performed on both the live......-oil-derived asphaltenes and the standard asphaltenes as precipitated by atmospheric titration on the same crude oil, revealed that the live-oil asphaltenes had apparent smaller hydrodynamic volume and narrower distributions than the standard asphaltenes for two oils. Further FTIR tests also showed large differences...

Oil sands to the rescue: oil sand microbial communities can degrade recalcitrant alkyl phenyl alkanoic acids

Energy Technology Data Exchange (ETDEWEB)

Whitby, Corinne [University of Essex (Canada)], email: cwhitby@essex.ac.uk

2011-07-01

Almost half of all global oil reserves are found as biodegraded heavy oils found in vast tar sand deposits located in North and South America and these account for 47% of Canadian oil production. Oil sand extraction generates large amounts of toxic waste water, known as oil sand process waters (OSPW), that are stored in large tailing ponds that contain toxic compounds like naphthenic acids (NAs). The presence of NAs creates problems like toxicity, corrosion, and the formation of calcium napthenate deposits which block pipelines and other infrastructure and need to be removed. This paper presents oil sand microbial communities that can degrade these NAs. The approach is to apply new aliphatic and aromatic NAs as substrates to supplement and identify NA degrading microbes and also to identify the metabolites produced and explain NA degradation pathways and the functional genes involved. The chemistry and the processes involved are explained. From the results, it is suggested that pure cultures of P. putida KT2440 be used against NAs.

Oil and natural gas

International Nuclear Information System (INIS)

Hamm, Keith

1992-01-01

The two major political events of 1991 produced a much less dramatic reaction in the global oil industry than might have been expected. The economic dislocation in the former USSR caused oil production to fall sharply but this was largely offset by a concurrent fall in demand. Within twelve months of the invasion of Kuwait, crude oil prices had returned to their pre-invasion level; there was no shortage of supply due to the ability of some producers to boost their output rapidly. Details are given of world oil production and developments in oil demand. Demand stagnated in 1991 due to mainly to the economic chaos in the former USSR and a slowdown in sales in the USA; this has produced problems for the future of the refining industry. By contrast, the outlook for the natural gas industry is much more buoyant. Most clean air or carbon emissions legislation is designed to promote the use of gas rather than other hydrocarbons. World gas production rose by 1.5% in 1991; details by production on a country by country basis are given. (UK)

Modelling the oil producers: Capturing oil industry knowledge in a behavioural simulation model

International Nuclear Information System (INIS)

Morecroft, J.D.W.; Van der Heijden, K.A.J.M.

1992-01-01

A group of senior managers and planners from a major oil company met to discuss the changing structure of the oil industry with the purpose of improving group understanding of oil market behaviour for use in global scenarios. This broad ranging discussion led to a system dynamics simulation model of the oil producers. The model produced new insights into the power and stability of OPEC (the major oil producers' organization), the dynamic of oil prices, and the investment opportunities of non-OPEC producers. The paper traces the model development process, starting from group discussions and leading to working simulation models. Particular attention is paid to the methods used to capture team knowledge and to ensure that the computer models reflected opinions and ideas from the meetings. The paper describes how flip-chart diagrams were used to collect ideas about the logic of the principal producers' production decisions. A sub-group of the project team developed and tested an algebraic model. The paper shows partial model simulations used to build confidence and a sense of ownership in the algebraic formulations. Further simulations show how the full model can stimulate thinking about producers' behaviour and oil prices. The paper concludes with comments on the model building process. 11 figs., 37 refs

2008-01-01

Cotton stalk was fast pyrolyzed at temperatures between 480 deg. C and 530 deg. C in a fluidized bed, and the main product of bio-oil is obtained. The experimental result shows that the highest bio-oil yield of 55 wt% was obtained at 510 deg. C for cotton stalk. The chemical composition of the bio-oil acquired was analyzed by GC-MS, and its heat value, stability, miscibility and corrosion characteristics were determined. These results showed that the bio-oil obtained can be directly used as a fuel oil for combustion in a boiler or a furnace without any upgrading. Alternatively, the fuel can be refined to be used by vehicles. Furthermore, the energy performance of the pyrolysis process was analyzed. In the pyrolysis system used in our experiment, some improvements to former pyrolysis systems are done. Two screw feeders were used to prevent jamming the feeding system, and the condenser is equipped with some nozzles and a heat exchanger to cool quickly the cleaned hot gas into bio-oil

The head of one of the world's biggest oil companies said in February that the era of oil dominating the global energy market is creaking to a close. Future energy needs will be met by a mix of fuels that are less harmful to the environment, he said, and he called for the energy and automobile industries to collaborate on solutions to reduce emissions.“We've embarked on the beginning of the last days of the age of oil,” ARCO Chairman Mike Bowlin said at a Cambridge Energy Research Associates conference in Houston, Texas, where he also described how ARCO is moving toward a new energy model. “Our challenge is not merely to survive today's low prices, but to plan for a future in which hydrocarbons are just one of a wide variety of clean fuels that will build the global economy of the 21st century”.

Heavy oil in Saskatchewan: Building on strengths

International Nuclear Information System (INIS)

1994-02-01

Saskatchewan has reserves of 17.6 billion bbl of heavy oil located in the west-central part of the province. The first oil well was drilled in 1945 and production of heavy oil has increased gradually, reaching 79,000 bbl/d in 1992. In recent years, the production pattern has not matched trends in investment; since 1982/83, the relative proportion of heavy oil drilling has declined significantly. A study is presented which analyzes trends in heavy oil investment, production, economics, and markets, with a focus on determining the causes for lack of investment in the heavy oil sector and evaluating the opportunities and constraints for long-term sustainability of this industry. Industry background is provided, with presentation of the key resource characteristics, reserve potential, and production and investment trends. Markets both in Canada and the USA are analyzed in detail, possible future trends are suggested. The effect of development of refinery capacity on heavy oil developments is examined. The logistics of shipping heavy oil to markets are detailed. The economics of Saskatchewan heavy oil production are established, taking into account all relevant cost components including taxes, royalties, and netbacks to producers. Issues of relevance affecting the heavy oil industry are discussed, including the need for environmental safeguards. 25 figs., 24 tabs

Is Exposure to Macondo Oil Reflected in the Otolith Chemistry of Marsh-Resident Fish?

Science.gov (United States)

López-Duarte, Paola C; Fodrie, F Joel; Jensen, Olaf P; Whitehead, Andrew; Galvez, Fernando; Dubansky, Benjamin; Able, Kenneth W

2016-01-01

Genomic and physiological responses in Gulf killifish (Fundulus grandis) in the northern Gulf of Mexico have confirmed oil exposure of resident marsh fish following the Macondo blowout in 2010. Using these same fish, we evaluated otolith microchemistry as a method for assessing oil exposure history. Laser-ablation inductively-coupled-plasma mass spectrometry was used to analyze the chemical composition of sagittal otoliths to assess whether a trace metal signature could be detected in the otoliths of F. grandis collected from a Macondo-oil impacted site in 2010, post-spill relative to pre-spill, as well as versus fish from areas not impacted by the spill. We found no evidence of increased concentrations of two elements associated with oil contamination (nickel and vanadium) in F. grandis otoliths regardless of Macondo oil exposure history. One potential explanation for this is that Macondo oil is relatively depleted of those metals compared to other crude oils globally. During and after the spill, however, elevated levels of barium, lead, and to a lesser degree, copper were detected in killifish otoliths at the oil-impacted collection site in coastal Louisiana. This may reflect oil contact or other environmental perturbations that occurred concomitant with oiling. For example, increases in barium in otoliths from oil-exposed fish followed (temporally) freshwater diversions in Louisiana in 2010. This implicates (but does not conclusively demonstrate) freshwater diversions from the Mississippi River (with previously recorded higher concentrations of lead and copper), designed to halt the ingress of oil, as a mechanism for elevated elemental uptake in otoliths of Louisiana marsh fishes. These results highlight the potentially complex and indirect effects of the Macondo oil spill and human responses to it on Gulf of Mexico ecosystems, and emphasize the need to consider the multiple stressors acting simultaneously on inshore fish communities.

Oil and gas property transfers: Analyzing the environmental risk through the environmental site assessment process

International Nuclear Information System (INIS)

Bratberg, D.; Hocker, S.

1994-01-01

The Superfund Act made anyone buying contaminated real estate liable for cleanup costs whether they know about the contamination or contributed to the contamination. In 1986, SARA amended the Superfund Act to include a provision known as the ''Innocent Landowner Defense.'' This provision created a defense for purchasers of contaminated property who did not contribute to the contamination and had no reason to believe that the property was contaminated at the time of the real estate transfer. SARA allows the purchasers and lenders to perform an environmental assessment using ''due diligence'' to identify contamination problems existing at a site. Since the passing of SARA, the environmental site assessment (ESA) process has become commonplace during the transfer of commercial real estate. Since the introduction of SARA, many professional associations, governmental agencies, and proposed federal legislation have struggled to produce a standard for conducting Phase 1 ESAs. Only recently has a standard been produced. Until recently, the domestic oil and gas industry has been relatively unconcerned about the Superfund liability issues. This approach was created by Congress's decision in 1980 to temporarily exempt the majority of oil and gas exploration and production wastes from federal hazardous waste rulings. However, new stringent rules governing oil and gas waste management practices are being considered by federal and state regulatory agencies. Based upon this knowledge and the awakening of public awareness, the use of ESAs for oil and gas transactions is increasing

Oil and Gas in the Arab world

The state of oil and gas production in each of twelve Arab states in 1996 is reviewed. A table of proved oil reserves and production in these countries as at the end of 1995 is provided. For Arab oil producers, 1996 was a good year in price terms. Crude oil was selling at an average of $3 a barrel more than in 1995. Factors contributing to prices rises were the increase in demand accompanying global economic growth, especially in the developing economies of Asia, which was not matched by supply growth, and the news that Iraq is unlikely to return to international markets in the near future.

Oil and monetarism do not mix

Energy Technology Data Exchange (ETDEWEB)

Johnson, C

1983-01-01

Monetarist policies, together with the second oil price shock, intensified global economic problems. Monetarism was adopted to prevent a repeat of the rapid inflation following the 1973-1974 oil price increase. The resulting high interest and exchange rates and high unemployment have affected even those countries that didn't convert to monetarism, with developing countries suffering the most. As an oil producer and despite the North Sea resources, the United Kingdom has had an especially bad tradeoff between inflation and growth. A better policy than monetarism would have been accommodation of a short-term inflaction moderated by an effective income policy. (DCK)

Ontario's petroleum legacy : the birth, evolution and challenges of a global industry

2008-01-01

This book provided a historical account of Ontario's role in the global oil industry, from the coming in of the first wells at Oil Springs in the mid-19th century when the primary fuel sources were wood, coal, and water. In 1858, oil seeps in Enniskillen Township, Lambton County, Ontario revealed the existence of petroleum, which encouraged the first drilling of wells and the development of the global industry. The book explored issues related to imperialism, resource development, local history and the colonial land policies surrounding the oil boom. Details of the Petrolia oil discovery were included along with the accomplishments of the entrepreneurs who were instrumental in developing the petroleum industry in Ontario. The major elements surrounding the development of Canada's oil and gas industry were presented, beginning with the coal-oil-refining industry which paved the way for the development of the oil industry; the early oilmen from Oil Springs and Petrolia who drilled for oil; the development of the oil and gas industry's position today as a major strength of the Canadian economy; and the environmental and climate change issues that currently confront the industry. After 150 years, the oil fields at Petrolia and Oil Springs still produce commercial quantities of crude oil from at least 650 active wells. refs., figs

Stigmastadiene and specific extitntion (270 nm to evaluate the presence of refined oils in virgin olive oil commercialized in Brazil

Directory of Open Access Journals (Sweden)

Sabria Aued-Pimentel

2013-09-01

Full Text Available The increased marketing of olive oil in Brazil has intensified legal requirements to ensure regulation of this product. The measurement of the specific extinction at 270 nm (E 270 and content of stigmastadiene can be used to assess the presence of refined oils in virgin olive oil. During the vegetable oil refining process, compounds with conjugated double bonds are generated from unsaturated fatty acids that absorb at 270 nm and sterols, such as stigmasta-3,5-diene. To compare these parameters, seven samples of extra virgin olive oil and three samples of olive oil (blend of virgin and refined were analyzed. Among the samples analyzed, four extra virgin samples had levels of stigmastadiene and E 270 higher than expected, among which two were adulterated with seed oil (rich in linoleic acid and the other two with olive pomace oil. The results demonstrate the higher sensitivity of stigmastadiene to determine the presence of the refined oil in virgin olive oil and good agreement with determining E 270. The latter technique is a simple, quick, and low cost method of determination that can be easily implemented in laboratories to assist in the screening and regulation of olive oils sold in Brazil.

Peak oil and gas

Ziegler, W. H.; Campbell, C. J.; Zagar, J.J.

2009-01-01

Oil and gas were formed under exceptional conditions in the geological past, meaning that they are subject to natural depletion, such that the past growth in production must give way to decline. Although depletion is a simple concept to grasp, public data on the resource base are extremely unreliable due to ambiguous definitions and lax reporting. The oil industry is reluctant to admit to an onset of decline carrying obvious adverse financial consequences. There are several different categories of oil and gas, from tar sands to deep water fields, each with specific characteristics that need to be evaluated. It is important to build a global model on a country by country basis in order that anomalous statistics may be identified and evaluated. Such a study suggests that the world faces the onset of decline, with far-reaching consequences given the central role of oil-based energy. It is accordingly an important subject deserving detailed consideration by policy makers. (author)

US oil dependency: 1973-1997

International Nuclear Information System (INIS)

Noel, P.

1998-11-01

This piece examines the behavior of US oil imports since the first oil shock, and compares with other big importers Europe and Japan. The relative share of Persian Gulf oil in foreign supply to the US is explained in terms of ''swing supplier'', and is shown to evolve in direct relation with the imports themselves: up when they are growing; down when imports go down. This relation broke up at the beginning of the 1990: despite growing US imports, Gulf share is declining. The reason is a regionalization (meaning the pan-Americanization) of US oil imports: the share of Latin American (Mexican and Venezuelan) and Canadian oil is growing steadily at the expense of non American suppliers. Hence the papers questions the chance of a emancipation of the US from Gulf oil and its geopolitical consequences. We argue that even in the case of a complete regionalization of oil imports, US energy security would still depend on the stability in the Middle-East, because of the ''unified'' and global nature of the oil market. An emancipation of the US from the Gulf is not impossible (though certainly not certain) but an emancipation of the Gulf from the US is all but imminent. (author)

AN INTER-TEMPORAL ANALYSIS OF OPERATIONAL EFFICIENCY OF OIL FIRMS: FURTHER EVIDENCE FROM NIGERIA

Directory of Open Access Journals (Sweden)

David Mautin Oke

2013-01-01

Full Text Available There have been growing needs to investigate oil and gas firms more closely due to their corporate scandals. Globally, oil firm managements have become more risk intolerant. They are sometimes under pressure to deliver results within a short time, which often negatively affect their ability to undertake risky ventures that are rewarding.Applying the Data Envelopment Analysis, this paper shows a high level of technical operational inefficiency of 0.51 in Nigerian oil industry over the period 2006-2009. The fall in technical efficiency of the oil firms in 2009 might be attributed to the banking crisis in Nigeria in 2009 that affected financial operations of some oil firms that relied on banking credits for running their business, and the fall in global oil prices relative to mid 2008.

Effect of NiO/SiO2 on thermo-chemical conversion of waste cooking oil to hydrocarbons

Directory of Open Access Journals (Sweden)

J. Sani

2017-05-01

Full Text Available Increase in organic waste generation, dwindling nature of global oil reserves coupled with environmental challenges caused by waste oil disposal and burning of fossil fuels necessitated the need for alternative energy resources. Waste cooking oil obtained from the frying fish outlet was analyzed for its physicochemical properties using ASTM D-975 methods. Acid and Iodine values of the oil were 30.43 ± 0.32 mgKOH/g and 57.08 ± 0.43 mgI2/100 g respectively. Thermo-chemical conversion of the oil using NiO/SiO2 at different reaction conditions (pressure, temperature, and catalyst concentration at a residence time of 3 h yielded 33.63% hydrocarbons. Hydro-catalytic pyrolysis of waste cooking oil at 400 °C, H2 pressure of 15 bars, and catalyst to oil ratio of 0.25 g/100 cm3 resulted in highest hydrocarbon yield (41.98%. The fuel properties of the product were: cetane number (71.16, high heating value (41.43 MJ/kg, kinematic viscosity (2.01 mm2/s, density (0.94 g/ml, saponification value (185.1 ± 3.96 mgKOH/g, and iodine value (20.57 ± 0.20 I2/100 g respectively. These results show that the NiO/SiO2 could be a suitable catalyst for conversion of waste vegetable oil to hydrocarbons. Keywords: Energy, Chemical engineering

Dynamic International Oil Market Developments and Structure 1860-1990 discusses the logic of changing market structures of the international oil industry. The market structures have, in the course of time, oscillated between competition and oligopoly, as the oil market expanded, matured, stagnated, and expanded again. This book provides a dynamic interpretation of the intensifying struggle among producer, and consumer governments, and oil companies, over the distribution of economic rents and profits. In particular, it shows the shifting fortunes of the governments and companies as they try to control the recurring capacity constraints between the upstream and downstream sectors, generated by the instability of the oil market. The first part of the book examines market conditions and developments between 1860 and 1990; the second part analyzes market structures after 1945

Numerical study on oil supply system of a rotary compressor

International Nuclear Information System (INIS)

Wu, Jianhua; Wang, Gang

2013-01-01

The oil supply system is a crucial reliability issue for rotary compressors. This paper provides a general method for analyzing the oil supply system of a rotary compressor by using computational fluid dynamics (CFD). The process includes establishing the physical model, dividing computational grid, setting boundary conditions, calculating leakage rates through the roller end clearances, translating the dynamic issue into the static issue and so on. Validation of the rationality of the oil supply system model has been made by the measurement of the main bearing oil flow rates. The effects of operating conditions of the compressor, the oil level height of the oil sump and the main design parameters of the oil supply system on the oil supply characteristics are analyzed by numerical simulation. It is found that the main bearing oil flow rate varies circularly along with the rotation of the shaft. The shape and inclination angle of the spiral groove also influence the main bearing oil flow rate. The oil leakage rates through the roller end clearances depend largely on the operating conditions. In addition, the oil level height of the oil sump has a huge effect on the total oil flow rate. -- Highlights: • A CFD method for analyzing the oil supply system of rotary compressor is presented. • Leakage through the roller end clearances depends on the operating condition. • Groove shape and inclination angle are the main design parameters of spiral grooves. • A parabolic interface of oil and gas can be formed in the gallery of the shaft. • Single-flow model and steady solver can be applied to the oil supply system

World oil prices, precious metal prices and macroeconomy in Turkey

International Nuclear Information System (INIS)

Soytas, Ugur; Sari, Ramazan; Hammoudeh, Shawkat; Hacihasanoglu, Erk

2009-01-01

We examine the long- and short-run transmissions of information between the world oil price, Turkish interest rate, Turkish lira-US dollar exchange rate, and domestic spot gold and silver price. We find that the world oil price has no predictive power of the precious metal prices, the interest rate or the exchange rate market in Turkey. The results also show that the Turkish spot precious metals, exchange rate and bond markets do not also provide information that would help improve the forecasts of world oil prices in the long run. The findings suggest that domestic gold is also considered a safe haven in Turkey during devaluation of the Turkish lira, as it is globally. It is interesting to note that there does not seem to be any significant influence of developments in the world oil markets on Turkish markets in the short run either. However, transitory positive initial impacts of innovations in oil prices on gold and silver markets are observed. The short-run price transmissions between the world oil market and the Turkish precious metal markets have implications for policy makers in emerging markets and both local and global investors in the precious metals market and the oil market.

Globalisation in the form of access to overseas markets and a growing integration of the world economy has in general been an engine of mutual enrichment. The great power of globalisation can be seen in the strength of its lifeline. As a report of the International Monetary Fund dryly stated, globalisation reflects the growing economic interdependence of countries worldwide through the increasing volume and variety of cross-border transactions in goods and services and of international capital flows, and also through the more rapid and widespread diffusion of technology. This hydra-headed growth is more than other macroeconomic trend. It is shaping a new epoch where the tempo and breadth of change in the international economy both alters the character of the multinational corporation and makes porous the economic frontiers of the state. Result: a different paradigm of opportunities and interdependencies, as well as new terms and conditions for competitive success. Big oil companies are old hands at globalisation in terms of geographic reach and in the ethnic diversity of their leadership. But the way they approach the world is changing in response to a more competitive market in developmed countries. Faced with a forecast of demand growth of a mere 1 or 2 percent in OECD nations, the petroleum giants are hoping to benefit from recent and prospective de-regulation of state-run monopolies in other parts of the world. As a result, they are vigorously making new downstream investments in emerging economies. But for them, globalisation has yet another dimension - the quest for true enterprise integration via big investments in new communications and information systems. According to an OECD study, by the year 2020 a third of world output could be accounted for by China (with the biggest economy), Russia, India, Indonesia and Brazil. Over the intervening years, all developing

Proceedings of the World Heavy Oil Congress : unconventional oil challenging conventional expectations

International Nuclear Information System (INIS)

2008-01-01

This international technical and business conference provided a forum to promote heavy oil technology and foster relationships between supply and demand countries. The interactive forum between global industry professionals addressed technological, strategic and environmental challenges facing the unconventional oil industry, including seeking innovative, low cost technologies, driving high costs down; educating and leading the workforce to maintain high standards of production; and ensuring that the footprint on the land is as light as possible. It emphasized that as demand for the uses of heavy oil grows, so does the responsibility of managing sustainability not just from an environmental and social perspective, but also with respect to supply, including manpower and infrastructure. The technical conference featured sessions on advanced and enhanced processes; combustion processes; drilling and completions; geology and reservoir; heavy oil exploitation and development; mining, extraction and transportation; non thermal processes; production and operations; reservoir monitoring; SAGD processes; sustainable development; thermal processes; and, upgrading technology. All 124 presentations from the technical conference were catalogued separately for inclusion in this database. refs., tabs., figs

Financial market pressure, tacit collusion and oil price formation

International Nuclear Information System (INIS)

Aune, Finn Roar; Rosendahl, Knut Einar; Mohn, Klaus; Osmundsen, Petter

2010-01-01

We explore a hypothesis that a change in investment behaviour among international oil companies (IOC) towards the end of the 1990s had long-lived effects on OPEC strategies, and on oil price formation. Coordinated investment constraints were imposed on the IOCs through financial market pressures for improved short-term profitability in the wake of the Asian economic crisis. A partial equilibrium model for the global oil market is applied to compare the effects of these tacitly collusive capital constraints on oil supply with an alternative characterised by industrial stability. Our results suggest that even temporary economic and financial shocks may have a long-term impact on oil price formation. (author)

Oil price volatility and the asymmetric response of gasoline prices to oil price increases and decreases

International Nuclear Information System (INIS)

Radchenko, S.

2005-01-01

This paper analyzes the effect of volatility in oil prices on the degree of asymmetry in the response of gasoline prices to oil price increases and decreases. Several time series measures of the asymmetry between the responses of gasoline prices to oil price increases and decreases and several measures of the oil price volatility are constructed. In all models, the degree of asymmetry in gasoline prices declines with an increase in oil price volatility. The results support the oligopolistic coordination theory as a likely explanation of the observed asymmetry and are not consistent with the standard search theory and the search theory with Bayesian updating.

Antioxidants help prevent lipid oxidation, and therefore are critical to maintain sensory quality and chemical characteristics of edible oils. Jussara berry (Euterpe edulis M.) oil is a source of minor compounds with potential antioxidant activity. The aim of this work was to investigate the role of such compounds on the effectiveness to prevent or delay oxidation of oil present in oil-in-water emulsions, and how the emulsions physical stability would be affected. Jussara berry oil extracted by ethanol extraction, its stripped variations (partially stripped, highly stripped and highly stripped with added BHT), and expeller pressed oil were used to prepare oil-in-water emulsions. Jussara berry oils were analyzed before emulsions preparation to ensure its initial quality and composition, and oil-in-water emulsions were analyzed regarding their oxidative and physical stability. Ethanol extracted oil emulsion presented higher oxidative stability when compared to highly stripped oil emulsion with added synthetic antioxidant BHT (oxidative stability index 45% lower, after 60 days, and reached undetectable levels after 90 days). All emulsions maintained physically stable for up to 120 days of storage. Our results indicate that natural antioxidants in jussara berry oil protect emulsions from oxidation while keeping physical stability unchanged. This article is protected by copyright.

Dynamic impacts of high oil prices on the bioethanol and feedstock markets

International Nuclear Information System (INIS)

Cha, Kyung Soo; Bae, Jeong Hwan

2011-01-01

This study investigates the impacts of high international oil prices on the bioethanol and corn markets in the US. Between 2007 and 2008, the prices of major grain crops had increased sharply, reflecting the rise in international oil prices. These dual price shocks had caused substantial harm to the global economy. Employing a structural vector auto-regression model (SVAR), we analyze how increases in international oil prices could impact the prices of and demand for corn, which is used as a major bioethanol feedstock in the US. The results indicate that an increase in the oil price would increase bioethanol demand for corn and corn prices in the short run and that corn prices would stabilize in the long run as corn exports and feedstock demand for corn decline. Consequently, policies supporting biofuels should encourage the use of bioethanol co-products for feed and the development of marginal land to mitigate increases in the feedstock price. - Research highlights: → World economy experienced 'dual shocks', which were caused by skyrocketed oil prices and grain prices between 2007 and 2008. → Sharp increases in ethanol production in response to high oil prices were considered as a major driving force to 'ag-flation' in the United States. → Applying a time series econometric tool, called the 'structural vector auto-regression model', we evaluated relationship between ethanol production and corn prices. → The result shows that ethanol production affects corn prices in the short run, while corn prices are lowered as other corn demands (feed for livestock or export demand) decline in the long run.

Big accumulations found in the past are not likely to occur again. On the contrary several small size accumulations may still be there unless a new play be discovered such as the sub salt. With global demand for oil rapidly increasing and easy oil becoming scarcer, we need to start looking at more difficult reservoirs from which to produce hydrocarbons. To boost daily global oil supplies to 100 million barrels, against current levels of some 85 million barrels, will be 'extremely difficult to reach' as we have heard in the news. It is not a question of available oil reserves, but a combination of technology, geopolitics and actual production decline in existing fields. Geopolitics and depletion rates are highly complex variables upon which we do not have full control. However Technology can still be designed fit for purposes. (author)

Colombian fusel oil

Natalia Montoya

2016-05-01

Full Text Available By-products valorization in bio-fuels industry is an important issue for making the global process more efficient, more profitable and closer to the concept of biorefinery. Fusel oil is a by-product of bioethanol production that can be considered as an inexpensive and renewable raw material for manufacturing value-added products. In this work, results in terms of composition and physicochemical properties of six samples of fusel oil from industrial alcohol facilities are presented. Composition of the main components was established by gas chromatography. Complementary techniques, such as headspace solid-phase microextraction and gas chromatography–mass spectrometry (GC-MS, were used for detection of minor components. Fifty-five compounds were identified. Physicochemical properties such as density, acid value, moisture content and true boiling point curves were determined. Results are useful in the conceptual design of separation strategies for recovering higher alcohols, as well as to consider new options of valorization alternatives for fusel oil.

Global risks from energy consumption

von Hippel, F.

1983-01-01

A discussion of some of the global risks associated with current and frequently proposed future levels of consumption of energy from oil, coal, fission, fusion, and renewable sources points out the the dangers are serious and relatively near term. These include world war over Persian Gulf oil, climate change due to the buildup of atmospheric carbon dioxide, the accelerated proliferation of nuclear weapons, and competition between food and energy for land and water. The author urges placing a greater emphasis on how we use energy and how to reduce energy waste. At the levels of consumption which economically justified levels of energy efficiency could bring about, enough flexibility could develop in our choice of a future energy-supply mix to dramatically reduce the associated global risks. 47 references, 3 figures

Acetylation of oil palm empty fruit bunch fiber as an adsorbent for removal of crude oil.

2016-06-01

Removal of oil spillage from the environment is a global concern. Various methods, including the use of fibers as sorbents, have been developed for oil spill control. Oil palm empty fruit bunch (OPEFB) fiber is a plant biomass that may be acetylated by acetic anhydride using N-bromosuccinimide (NBS) as a catalyst; here, the extent of acetylation may be calculated in terms of weight percent gain (WPG). The modified fiber was used to remove Tapis and Arabian crude oils. The optimum time, temperature, and catalyst concentration were 4 h, 120 °C, and 3 %, respectively, and these parameters could achieve an 11.49 % increase in WPG. The optimized parameters improved the adsorption capacity of OPEFB fibers for crude oil removal. The acetylated OPEFB fibers were characterized by using Fourier transform infrared spectroscopy and field emission scanning electron microscopy to observe the functional groups available and morphology. Kinetic and isotherm studies were conducted using different contact times and oil/water ratios. The rate of oil sorption onto the OPEFB fibers can be adequately described by the pseudo-second-order equation. Adsorption studies revealed that adsorption of crude oil on treated OPEFB fiber could be best described by the Langmuir isotherm model.

Pyrolysis oil as diesel fuel

Wood waste pyrolysis oil is an attractive fuel alternative for diesel engine operation. The main benefit is the sustainability of the fuel. No fossil reserves are consumed. The fact that wood waste pyrolysis oil does not contribute to CO{sub 2} emissions is of utmost importance. This means that power plants utilising pyrolysis oil do not cause additional global warming. Equally important is the reduced sulphur emissions that this fuel alternative implies. The sulphur content of pyrolysis oil is extremely low. The high water content and low heating value are also expected to result in very low NO{sub x} emissions. Utilisation of wood waste pyrolysis oil in diesel engines, however, involves a lot of challenges and problems to be solved. The low heating value requires a new injection system with high capacity. The corrosive characteristics of the fluid also underline the need for new injection equipment materials. Wood waste pyrolysis oil contains solid particles which can clog filters and cause abrasive wear. Wood waste pyrolysis oil has proven to have extremely bad ignition properties. The development of a reliable injection system which is able to cope with such a fuel involves a lot of optimisation tests, redesign and innovative solutions. Successful single-cylinder tests have already been performed and they have verified that diesel operation on wood pyrolysis oil is technically possible. (orig.)

Full Text Available The present concept of being globally “green” puts additional demands on lubricants. They are to be biodegradable and ecofriendly. Therefore, in a search for alternate lubricants meeting the above demands, we have synthesized biodegradable new generation esters using alcohols such as 2,2-dimethyl-1,3-propane diol and 2,2-diethyl-1,3-propane diol and fatty acids like caproic and 2-ethyl caproic in presence of indigenous ion exchange resin catalyst. The synthesized esters were analyzed and characterized for their physico chemical properties. In addition, with a view to finding out the possibility of using these esters as aluminum cold rolling oils, their lubricity characteristics, biodegradability and toxicity were also investigated. The products were found to have good potential for use in biodegradable aluminum cold rolling oils meeting IS: 14385-2002 specification.

With Kuwait considering allowing foreign investment in its upstream oil sector, political opposition remains at the parliamentary level. The internal debate between government ministers who favour the potential $7bn investment in their economy, and politicians concerned about foreign control of this essential national asset is described in this article. This politically volatile region, with its recent experience of the Iran/Iraq war, still maintains itself in readiness in case of invasion, and badly needs the foreign investment in order to raise current production levels because of low global oil prices.

Birjandi, Hossein Saremi

Before the Industrial Revolution, nations required no energy fuel. People relied on human, animal, and wind and waterpower for energy need. Energy (oil) has resettled populations, elected officials in the free world, or changed the governments of the energy rich countries by force. Energy fueled wars, played the major factor in the might of those who have it or more importantly the abilities to acquire it by force. This dissertation researches the primacy of oil as an energy source from the time of oil's discovery to the present times. Between 1945 and 1960, the use of oil and gas doubled as power was generated for industries as steel, cement, metalworking and more important of all filling station hoses into automobiles gas tanks, thus energy swept people and societies quite literally off their feet. One in every six jobs in the industrial world hired by the giant automotive industries. The big five American oil companies spurred on by special tax benefit, these companies grew to gigantic sizes by taking out the best part of the nation's oil. Then, for greater growth, they leaped overseas and built up an immensely profitable system, in alliance with Anglo-Dutch Shell and British Petroleum, known as seven sisters. On the other side of the world, the energy producing nations form an alliance mainly to protect themselves from downward price fluctuations of oil. The struggle for survival in the global energy market forced those countries to get together and form OPEC, which is referred as an "oil cartel".

ECONOMIC CONSEQUENCES OF PEAK OIL FOR THE MAJOR MULTINATIONAL OIL AND GAS COMPANIES

Directory of Open Access Journals (Sweden)

Antonio García-Amate

2018-03-01

Full Text Available The main goal of this work is to analyze the financial statements of the five major multinational oil and gas companies, for the 2011-2015 period, in the framework of the peak oil phenomenon. Peak oil can affect key financial indicators (e.g., earnings volatility, leverage that are used by managers, investors, and stockholders and which may potentially lead to changes in the decision making by management. Our results show that the decline in oil production affects the decisions about investment in new oil wells, leverage, dividends paid, shares purchased and net income involving the five major companies. In addition, we study the evolution of oil prices, and its influence in several items of the financial statements. Even though oil prices were at high levels during 2011-2014, however, the net income of the five companies actually declined due to the impact of peak oil. Finally, data for the last year studied (2015 indicate a general deterioration in return ratios and other accounting variables. Although the new investments should have been profitable, they have been influenced by peak oil, compromising the economic position of the companies. The advice to these companies would be to relax their investments, especially during a period of falling oil prices. Company managers need to recognize the prolonged duration of peak oil and price trends to promote profitability recovery decisions.

An analysis of price and volatility transmission in butter, palm oil and crude oil markets

Directory of Open Access Journals (Sweden)

Dennis Bergmann

2016-11-01

Full Text Available Abstract Recent changes to the common agricultural policy (CAP saw a shift to greater market orientation for the EU dairy industry. Given this reorientation, the volatility of EU dairy commodity prices has sharply increased, creating the need to develop proper risk management tools to protect farmers’ income and to ensure stable prices for processors and consumers. In addition, there is a perceived threat that these commodities may be replaced by cheaper substitutes, such as palm oil, as dairy commodity prices become more volatile. Global production of palm oil almost doubled over the last decade while butter production remained relatively flat. Palm oil also serves as a feedstock for biodiesel production, thus establishing a new link between agricultural commodities and crude oil. Price and volatility transmission effects between EU and World butter prices, as well as between butter, palm oil and crude oil prices, before and after the Luxembourg agreement, are analysed. Vector autoregression (VAR models are applied to capture price transmission effects between these markets. These are combined with a multivariate GARCH model to account for potential volatility transmission. Results indicate strong price and volatility transmission effects between EU and World butter prices. EU butter shocks further spillover to palm oil volatility. In addition, there is evidence that oil prices spillover to World butter prices and World butter volatility.

The reference flow adopted for the work was the generation of power supplied 1GJ from the produced biodiesel. The data used in the inventory life cycle were calculated based on similar scientific papers. The method of assessment of environmental impacts chosen was the CML 2001 modified. Altogether, it were analyzed nine categories of environmental impacts for both processes (abiotic depletion (kg Sb eq, land use (m2a, global warming (kg CO2 eq, ozone layer depletion (kg CFC-11 eq, human toxicity (kg 1,4-DB eq, freshwater ecotoxicity (kg 1,4-DB eq, terrestrial ecotoxicity (kg 1,4-DB eq, acidification (kg SO2 eq and eutrophication (kg PO43- eq. The results of evaluation of environmental impacts show that the biodiesel production process from soybean oil presents major environmental damage in seven categories of analyzed impacts (destruction of abiotic resources, destruction of the ozone layer, human toxicity, freshwater ecotoxicity, terrestrial ecotoxicity, acidification and eutrophication. The production process of biodiesel from tallow presents major environmental damage in two categories of impacts analyzed (land use and global warming. However, the results show that the absolute values of environmental damage caused by impacts of the production process using beef tallow are much more aggressive.

The NORDTEST procedure (1) for oil spill identification has been applied successfully at several occasions. The NORDTEST procedure includes analyses of sulfur (XRF), vanadium and nickel (ICP/AAS), GC, HPLC and UV-fluorescence. The NORDTEST procedure does not include GC-MS as an analytical method. As part of a joint Nordic to evaluate the NORDTEST procedure for oil identification, with participants from Denmark, Sweden, Finland and Norway, thirty artificially weathered crude oils from four geographical regions have been analyzed (2). The analytical methods evaluated include sulfur analysis, vanadium and nickel analysis, infrared analysis, UV-fluorescence, gas chromatography, high pressure liquid chromatography and high resolution GC-mass spectrometry. Figure 1 shows the distribution of variables analyzed in each analytical method. The 190 variables from GC-MS were split into 7 groups according to chemical considerations. These were steranes (25 var.), triterpanes (16 var.), di(+)aromatics (63 var.), sulf. aromatics (30 var.), monoaromatics (19 var.), cycloalkanes (15 var.) and n-alkanes (22) variables. The data from these chemical analyses have been evaluated for use in oil spill identification purposes

The oil spills from the Agip Abruzzo and the Haven in April 1991 are described. The Agip Abruzzo collided with a ferry near Livorno, Italy and spilled 3,000 tonnes of Iranian crude oil. Another 12,000 tonnes burned and 140 people were killed in the incident. The spill had little effect on the sea environment as most of the spilled oil was removed. The Haven oil tanker exploded just after unloading crude oil at Arenzano, Italy, spilling 3,000 tonnes of oil along the Ligurian coast. A series of nine explosions occurred over the next few days and the ship finally sank in 60 m of water. Spill cleanup procedures used at sea and along the affected coast are reviewed. Crude oil residues drifting along the coast of the Balearic Islands were sampled and analyzed in May and July 1991 to determine whether they came from the Haven tanker. Experiments were also conducted to determine the evaporated fraction of heavy Iranian crude oil as a function of time when spilled on sea water or different sizes of beach sand. The analyzed samples were concluded not to have come from the Haven spill. 9 refs., 9 figs., 1 tab

Yang, Chi-Jen; Xuan, Xiaowei; Jackson, Robert B.

2012-01-01

Since China decontrolled coal prices, its coal price has risen steadily and been unusually volatile. In 2011 in particular, high coal prices and capped electricity prices in China discouraged coal-fired power generation, triggering widespread power shortages. We suggest that these coal-price disturbances could be symptomatic of a major change in pricing dynamics of global fossil-fuel markets, with increasing correspondence between coal and oil prices globally. Historically, global coal prices have been more stable and lower than oil and natural gas prices on a per-heat basis. In recent years, however, coal prices have been increasingly volatile worldwide and have tracked other fossil fuel prices more closely. Meanwhile, the recent development of unconventional gas has substantially decoupled US natural gas and oil prices. Technically, low US natural gas prices, with potential fuel switching, could drive US domestic coal prices lower. However, this effect is unlikely to counteract the overall trend in increasing coal consumption globally. China's market size and unique, partially-controlled energy system make its reform agenda a key force in the global economy. Policymakers in the US, E.U. and elsewhere should monitor China's economic reform agenda to anticipate and respond to changes accompanying China's increasing importance in the global energy economy. - Highlights: ► Since China decontrolled its coal prices, the price of coal has risen steadily in China, accompanied by unusual volatility. ► Relatively high and volatile coal prices have triggered widespread power shortages in China. ► Coal and oil prices have already become, and continue to become, more closely linked globally. ► China's demand will likely drive up global coal prices and make them as volatile as that of other fossil fuels. ► Policymakers should monitor China's economic reform agenda to anticipate and respond to changes in the global energy economy.

As the world's second largest oil importer, China has been one of the important factors which affect the global oil market. In recent years, China has attained great international trade surplus through exporting a large number of “Made in China” products even during the global economic crisis. Due to direct and indirect effects in production chain, each 'Made in China' product contains oil directly or indirectly. China is exporting much oil through “Made in China” products, which is not often considered even within China. An input–output model is established to calculate oil embodied in the international trade of China. The research results suggest the following: China's net oil exports embodied in the international trade were 87.02 million tonnes in 2007; manufacture of communication equipment, computers and other electronic equipment is the largest sector to export embodied oil; United States, China Hong Kong SAR and Netherlands are the top three countries and regions which benefit most from the embodied oil in “Made in China” products. China's adjusted degree of dependence on foreign oil is 24.9% in 2007, and 38.4% in 2011 if net oil exports embodied in international trade are considered. -- Highlights: ► Model is established based on IO analysis to calculate the net oil exports embodied in China's international trade. ► China's net oil exports through “Made in China” products are 87 million tones in 2007. ► United States, China Hong Kong SAR and Netherlands benefit most from the embodied oil in China's international trade. ► China's degree of dependence on foreign oil can be reduced obviously if oil embodied in international trade are considered.

Agar wood oil is well known as expensive oil extracted from the resinous of fragrant heartwood. The oil is getting high demand in the market especially from the Middle East countries, China and Japan because of its unique odor. As part of an on-going research in grading the agar wood oil quality, the application of Artificial Neural Network (ANN) is proposed in this study to analyze agar wood oil quality using its chemical profiles. The work involves of selected agar wood oil from low and high quality, the extraction of chemical compounds using GC-MS and Z-score to identify of the significant compounds as input to the network. The ANN programming algorithm was developed and computed automatically via Matlab software version R2010a. Back-propagation training algorithm and sigmoid transfer function were used to optimize the parameters in the training network. The result obtained showed the capability of ANN in analyzing the agar wood oil quality hence beneficial for the further application such as grading and classification for agar wood oil. (author)

Yew Hoong Gin, K.; Huda, Md. K.; Tkalich, P.

2001-01-01

An oil spill-food chain interaction model, composed of a multiphase oil spill model (MOSM) and a food chain model, has been developed to assess the probable impacts of oil spills on several key marine organisms (phytoplankton, zooplankton, small fish, large fish and benthic invertebrates). The MOSM predicts oil slick thickness on the water surface; dissolved, emulsified and particulate oil concentrations in the water column; and dissolved and particulate oil concentrations in bed sediments. This model is used to predict the fate of oil spills and transport with respect to specific organic compounds, while the food chain model addresses the uptake of toxicant by marine organisms. The oil spill-food chain interaction model can be used to assess the environmental impacts of oil spills in marine ecosystems. The model is applied to the recent Evoikos-Orapin Global oil spill that occurred in the Singapore Strait. (author)

Do food and oil prices co-move?

International Nuclear Information System (INIS)

Reboredo, Juan C.

2012-01-01

This paper studies co-movements between world oil prices and global prices for corn, soybean and wheat using copulas. Several copula models with different conditional dependence structures and time-varying dependence parameters were considered. Empirical results for weekly data from January 1998 to April 2011 showed weak oil-food dependence and no extreme market dependence between oil and food prices. These results support the neutrality of agricultural commodity markets to the effects of changes in oil prices and non-contagion between the crude oil and agricultural markets. However, dependence increased significantly in the last three years of the sampling period, even though upper tail dependence remained insignificant, indicating that food price spikes are not caused by positive extreme oil price changes. These results have implications for policy design, risk management and hedging strategies. - Highlights: ► We study co-movement between food and oil markets through copulas. ► Food prices are neutral to the effects of changes in oil prices. ► Oil price spikes had no causal effect on agricultural price spikes. ► Oil–corn and oil–soybean dependence increased in recent years. ► Food subsidy policies and price controls are unnecessary to avoid extreme oil prices.

A current EPA regulation prohibits the sale for burning in nonindustrial boilers of used oils and oil fuels. This paper discusses how analytical techniques for determining total chlorine were evaluated to provide regulatory agencies and the regulated community with appropriate chlorine test methods. The techniques evaluated included oxygen bomb combustion followed by chemical titration or ion chromatography, instrumental microcoulometry, field test kits, and instrumental furnace/specific ion electrode determinator, a device based on the Beilstein reaction, and x-ray fluorescence spectrometry. These techniques were subjected to interlaboratory testing to estimate their precision, accuracy, and sensitivity. Virgin and used crankcase oils, hydraulic and metalworking oils, oil fuels and oil fuel blends with used oils were tested. The bomb techniques, one of the test kits, microcoulometry and all but one x-ray analyzer were found to be suitable for this application. The chlorine furnace and the Beilstein device were found to be inapplicable at the levels of interest

The aim of this study is to discover the effectiveness of cocoa peel as biosorbents for oil and color removal in POME. This study used biosorbent from cocoa peel with variation of particle size which passed through 70 mesh, 100 mesh, and 120 mesh and was activated with the ratio of biosorbent and 0,6 M HNO3 of 1:2, 1:4, and 1:6 (m/v). The adsorption process was carried out using biosorbent with the highest iodine number in varying biosorbent mass and contact time. The highest iodine number was 596,684 mg/g and obtained at particle size 120 mesh and the ratio of biosorbent : HNO3 as 1 : 4. The resulting biosorbents were analyzed for their characterization, such as vapor content, ash content, and volatile matter, including FT-IR and SEM-EDX. The POME were analyzed for their oil and color content, using gravimetric method and UV-Vis spectrophotometry. The best removal is were 80,88% for oil and 83.45% for color at 1.5 g biosorbent mass and 3 h contact time. The resullt for oil removal was close to the standard of Indonesian Environment Minister for oil in effluent. Also the adsorption of oil and color behaves as a pseudo-second-order kinetic models.

A simple and accurate authentication method for the detection of adulterated vegetable oils that contain waste cooking oil (WCO) was developed. This method is based on the determination of cholesterol, β-sitosterol, and campesterol in vegetable oils and WCO by GC/MS without any derivatization. A total of 148 samples involving 12 types of vegetable oil and WCO were analyzed. According to the results, the contents and ratios of cholesterol, β-sitosterol, and campesterol were found to be criteria for detecting vegetable oils adulterated with WCO. This method could accurately detect adulterated vegetable oils containing 5% refined WCO. The developed method has been successfully applied to multilaboratory analysis of 81 oil samples. Seventy-five samples were analyzed correctly, and only six adulterated samples could not be detected. This method could not yet be used for detection of vegetable oils adulterated with WCO that are used for frying non-animal foods. It provides a quick method for detecting adulterated edible vegetable oils containing WCO.

Ji, Qiang; Geng, Jiang-Bo; Fan, Ying

2014-01-01

This paper analyses the impact of global economic activity and international crude oil prices on natural gas import prices in three major natural gas markets using the panel cointegration model. It also investigates the shock impacts of the volatility and the increase and decrease of oil prices on regional natural gas import prices. The results show that both global economic activity and international crude oil prices have significant long-term positive effects on regional natural gas import prices. The volatility of international crude oil prices has a negative impact on regional natural gas import prices. The shock impact is weak in North America, lags in Europe and is most significant in Asia, which is mainly determined by different regional policies for price formation. In addition, the response of natural gas import prices to increases and decreases in international crude oil prices shows an asymmetrical mechanism, of which the decrease impact is relatively stronger. - Highlights: • Impacts of world economy and oil prices on regional natural gas prices are analysed • North American natural gas prices are mainly affected by world economy • Asian and European natural gas prices are mainly affected by oil prices • The volatility of oil prices has a negative impact on regional natural gas prices • The response of natural gas import prices to oil prices up and down shows asymmetry

Crude oil contributes in Germany and globally approximately one third to the consumption of primary energies and actually is and in the foreseeable future will be the most important energy source. Recently shale oil as an unconventional oil has gained attention in public discussions. Depending on temperatures oil shale contains either already matured fluid shale oil or immature waxy kerogen. For determination of kerogen containing oil shale and shale oil common definitions for fluid hydrocarbons will be presented. Fluid hydrocarbons (molecular chains > C{sub 5}H{sub 12}) originate from animal substance which had been settled millions of years in sediments on sea- or lakebeds under anaerobic conditions. High pressure and high temperatures effect conversion to hydrocarbons. With sufficient permeability the liquid hydrocarbons migrate from the sediment as the source rock and get assembled in porous rocks under the cover of an impermeable rock strata, in so called entrapment structures. In case there is no impermeable rock strate the hydrocarbons will diffuse into the atmosphere. The hydrocarbons in entrapment structures are called conventional oil and are extracted by drilling wells. The extractable oil as part of the oil in place depends on the viscosity of the oil, the permeability of the host rock and applied exploitation methods which can affect pressure, viscosity and permeability. The exploitation achieves 30 to 50% of the oil in place. When the source rock consisting of strata hundreds of meters thick is not sufficiently permeable the matured hydrocarbons remain at its place of origination. These hydrocarbons are called shale oil and belong to the unconventional oil resources. For exploitation of shale oil by wells the source rock must be treated by intensive energy input, amongst others, by fracking which creates artificial permeability and by pressure which affects migration of the hydrocarbons to the well. The exploitation methods for shale oil do not

Prospects for oil and gas

Laherrere, J.

2011-01-01

It was five years ago, in January 2006, that Futuribles devoted a major special issue (no. 315) to energy prospects and the greenhouse effect. That was already a time of great concern about this question and several articles offered analyses of the gloomy prospects for the development of energy resources and the issues around climate change. Among these, an article by Jean Laherrere outlined the prospects for oil resources, showing the extent to which information in this area was disparate, unreliable and even questionable, being often highly political. As one of the more pessimistic writers on the question, Laherrere reminded us of the imminence of 'peak oil' (the prelude to a decline in global oil production) and the need to re-think our styles of consumption to adapt to a new age in which, as energy becomes scarcer, it will be increasingly expensive. Five years later, Jean Laherrere returns to the columns of Futuribles on the occasion of a new special issue on energy and the climate, to update us on the global prospects for oil and gas production. He begins by recalling how politically slanted and unreliable information in this area can be, depending on its source, the units of measurement employed etc. He stresses, too, that in the view of many experts peak oil was reached in 2006 and the situation is currently plateau-ing, just ahead of a decline in oil production (gradual or sudden, depending on whether measures of economic constraint are implemented). For its part, gas production should peak around 2025-2030. Jean Laherrere specifies what reserves remain, how these are currently exploited and marketed, and the prospects that ensue in the longer term (he also shows how wrong gas-price forecasts have been in the past). As he stresses, in conclusion, with both oil and gas we must be aware that the world does not have infinite resources and, since the alternatives do not allow us, at the moment, to make up for future energy-resource shortages, it is for

The dirty oil card and Canadian foreign policy

International Nuclear Information System (INIS)

Chastko, P.

2010-10-01

This paper discussed Canada's oil sands industry in relation to its international reputation as the source of an unacceptable amount of pollution. Environmental lobbyists and awareness groups have targeted Canada's oil sands industry as an example of how the oil industry contributes to pollution during the production phase. Media attention has focused on the oil sands as a heavy grade of crude oil that requires significant upgrading and refining before it can be produced as a barrel of usable oil. Canadian exports of oil sands to the United States have been the target of consumer boycotts and proposed legislation. A lack of available alternative energy sources and infrastructure for the transportation sector, and the continued global demand for petroleum mean that oil sands will continue to be exported to the United States as well as to other export markets such as China and India. The United States is likely to remain the largest importer of Canadian crude oils. However, policy-makers must ensure that the discourse about oil sands does not devolve into an argument in which energy security is pitted against the need for increased environmental protection. 49 refs.

The Impacts of Oil Palm on Recent Deforestation and Biodiversity Loss.

Directory of Open Access Journals (Sweden)

Varsha Vijay

Full Text Available Palm oil is the most widely traded vegetable oil globally, with demand projected to increase substantially in the future. Almost all oil palm grows in areas that were once tropical moist forests, some of them quite recently. The conversion to date, and future expansion, threatens biodiversity and increases greenhouse gas emissions. Today, consumer pressure is pushing companies toward deforestation-free sources of palm oil. To guide interventions aimed at reducing tropical deforestation due to oil palm, we analysed recent expansions and modelled likely future ones. We assessed sample areas to find where oil palm plantations have recently replaced forests in 20 countries, using a combination of high-resolution imagery from Google Earth and Landsat. We then compared these trends to countrywide trends in FAO data for oil palm planted area. Finally, we assessed which forests have high agricultural suitability for future oil palm development, which we refer to as vulnerable forests, and identified critical areas for biodiversity that oil palm expansion threatens. Our analysis reveals regional trends in deforestation associated with oil palm agriculture. In Southeast Asia, 45% of sampled oil palm plantations came from areas that were forests in 1989. For South America, the percentage was 31%. By contrast, in Mesoamerica and Africa, we observed only 2% and 7% of oil palm plantations coming from areas that were forest in 1989. The largest areas of vulnerable forest are in Africa and South America. Vulnerable forests in all four regions of production contain globally high concentrations of mammal and bird species at risk of extinction. However, priority areas for biodiversity conservation differ based on taxa and criteria used. Government regulation and voluntary market interventions can help incentivize the expansion of oil palm plantations in ways that protect biodiversity-rich ecosystems.

The author takes stock on the dynamic of the oil system. He shows how the economic laws can be applied to the petroleum market and analyzes the effects of the prices evolution. The creeping oil shock of 2003-2004 has proven less disruptive than one may have anticipated. Commodity cycles on the one hand the shaky management of marginal supply by OPEC on the other hand, are very likely to create ample prices swings with little relations, if any, to the actual scarcity-or lack thereof-of oil resources.

The rapid growth of domestic oil consumption in Saudi Arabia and the opportunity cost of oil exports foregone

International Nuclear Information System (INIS)

Gately, Dermot; Al-Yousef, Nourah; Al-Sheikh, Hamad M.H.

2012-01-01

We analyze the rapid growth of Saudi Arabia's domestic oil consumption, a nine-fold increase in 40 years, to nearly 3 million barrels per day, about one-fourth of production. Such rapid growth in consumption – 5.7% annually, which is 37% faster than its income growth of 4.2% – will challenge Saudi Arabia's ability to increase its oil exports, which are relied upon in long-term world oil projections by the International Energy Agency (IEA), US Department of Energy (DOE) and British Petroleum (BP). However, these institutions assume unprecedented slowdowns in Saudi oil consumption – from 5.7% annual growth historically to less than 2% in the future – allowing them to project increases in Saudi oil exports. Using 1971–2010 data, we estimate that the income responsiveness (elasticity) of oil consumption is at least 1.5—using both Ordinary Least Squares regression and Cointegration methods. We believe that continued high growth rates for domestic oil consumption are more likely than the dramatic slowdowns projected by IEA, DOE and BP. This will have major implications for Saudi production and export levels. - Highlights: ► We analyze the rapid growth of Saudi Arabia's domestic oil consumption, now one-fourth of production. ► Estimated income elasticity of oil demand at least 1.5, using OLS and Co-integration. ► Yet IEA, DOE and BP project unprecedented slowdowns, from 5.7% historically to below 2%, half the rate of income growth. ► Continued high growth rates are more likely, with major implications for Saudi production and export levels.

Oil prices, fiscal policy, and economic growth in oil-exporting countries

Science.gov (United States)

El-Anshasy, Amany A.

This dissertation argues that in oil-exporting countries fiscal policy could play an important role in transmitting the oil shocks to the economy and that the indirect effects of the changes in oil prices via the fiscal channel could be quite significant. The study comprises three distinct, yet related, essays. In the first essay, I try to study the fiscal policy response to the changes in oil prices and to their growing volatility. In a dynamic general equilibrium framework, a fiscal policy reaction function is derived and is empirically tested for a panel of 15 oil-exporters covering the period 1970--2000. After the link between oil price shocks and fiscal policy is established, the second essay tries to investigate the impact of the highly volatile oil prices on economic growth for the same sample, controlling for the fiscal channel. In both essays the study employs recent dynamic panel-data estimation techniques: System GMM. This approach has the potential advantages of minimizing the bias resulting from estimating dynamic panel models, exploiting the time series properties of the data, controlling for the unobserved country-specific effects, and correcting for any simultaneity bias. In the third essay, I focus on the case of Venezuela for the period 1950--2001. The recent developments in the cointegrating vector autoregression, CVAR technique is applied to provide a suitable framework for analyzing the short-run dynamics and the long-run relationships among oil prices, government revenues, government consumption, investment, and output.

Future role of Gulf oil in world energy demand

International Nuclear Information System (INIS)

Eltony, M.N.

1998-01-01

The view that there will be a growing dependence on oil from the Gulf countries is shared by a great number of oil market analysts. This view is based on the fact that Gulf countries dominate the global oil reserves. Energy analyst argue that as the world demand for oil continues to grow driven largely by the growth in developing countries' consumption coupled with constrained non-OPEC supply, the end result will be that the call on Gulf oil will grow substantially. In summary, this paper has challenged the view of growing dependence on oil from the Gulf using available information in conjunction with reasonable and fairly plausible arguments. The aim was to point out to the GCC member counties the danger of relying on these views in shaping their economic policies and in setting their oil market strategies. They may run the ultimate risk of being left with huge oil reserves that no one wants. (orig.)

The impact of oil prices on the banking system in the Gulf Cooperation Council

Directory of Open Access Journals (Sweden)

Padamja Khandelwal

2017-06-01

Full Text Available This paper examines the links between global oil price movements and macroeconomic and financial developments in the Gulf Cooperation Council (GCC. The GCC economies can be adversely affected by low oil prices due to their high dependence on oil and gas exports and macro-financial linkages which can amplify the effects of oil price movements over the financial cycle. Historically, systemic financial sector risks rose in the GCC countries with the oil price upswing in the years before the global financial crisis. Against this background, a range of multivariate panel approaches, including a panel vector autoregression approach, were applied to macroeconomic and bank-level data covering the six GCC economies and span 1999–2014. The paper finds strong empirical evidence of feedback loops between oil price movements, bank balance sheets, and asset prices. Empirical evidence also suggests that bank capital and provisioning have behaved countercyclically through the cycle. That is, these ratios increase during good times. This has helped strengthen the resilience of the financial system to the oil price decline since mid-2014.

Then, the impact of traditional and non-traditional exports on non-oil GDP investigated employing econometric model. The results of the study based on 16 non-oil commodities show that cotton, tobacco, and production of mechanic devices are traditional sectors in non-oil export. The estimation results of the model indicate that both, traditional and non-traditional non-oil export sectors have economically and statistically significant impact on non-oil GDP.

The formation and evolution of monoepoxy fatty acids, arising from oleic and linoleic acids, were investigated in olive oil and conventional sunflower oil, representatives of monounsaturated and polyunsaturated oils, respectively, during thermoxidation at 180 degrees C for 5, 10, and 15 h. Six monoepoxy fatty acids, cis-9,10- and trans-9,10-epoxystearate, arising from oleic acid, and cis-9,10-, trans-9,10-, cis-12,13-, and trans-12,13-epoxyoleate, arising from linoleic acid, were analyzed by gas chromatography after oil derivatization to fatty acid methyl esters. Considerable amounts, ranging from 4.29 to 14.24 mg/g of oil in olive oil and from 5.10 to 9.44 mg/g of oil in sunflower oil, were found after the heating periods assayed. Results showed that the monoepoxides quantitated constituted a major group among the oxidized fatty acid monomers formed at high temperature. For similar levels of degradation, higher contents of the monoepoxides were found in olive oil than in sunflower oil. Ten used frying oils from restaurants and fried-food outlets in Spain were analyzed to determine the contents of the monoepoxides in real frying oil samples. Levels ranged from 3.37 to 14.42 mg/g of oil. Results show that, for similar degradation levels, the monoepoxides were more abundant in the monounsaturated oils than in the polyunsaturated oils.

The paper outlines a conceptual framework for understanding and analyzing the structuring of an institutional order. Particular attention is given to developments that make institution restructuring likely--for instance power shifts which favor actors with a different vision or model of an appropriate institutional order. The framework is applied in a brief historical study of the development of post-World War II international economic institutions and current developments associated with the ''oil crisis.'' This conceptual framework and historical investigation provides a basis on which to formulate propositions, indicating potential sources of conflict and cooperating and certain ambiguities and dynamics of current institution restructuring in the international system. The paper concludes by outlining several action guidelines for structuring new global cultural forces and institutional forms related to bringing about a New International Economic Order. 43 references.

The 2008 oil bubble. Causes and consequences

International Nuclear Information System (INIS)

Tokic, Damir

2010-01-01

We argue that 'the 2008 Oil Bubble' was directly and indirectly created by the Federal Reserve in response to deflationary risks that resurfaced after the housing bubble burst and the resulting credit crisis of 2008. Deflationary risks first appeared after the dot.com bubble burst in 2000 and after the terrorist attacks on September 11, 2001. Manipulation of the US dollar value has been one of the key emergency tools in the Fed's arsenal. During the entire period from 2000 to 2008, the US dollar has been falling, while the price of crude oil has been rising, with the culmination in July 2008. If other global central banks embrace the Fed's anti-deflationary strategies, the consequences could be dire for the global economy, potentially resulting in an ultimate gold bubble. (author)

Canada accounts for 40% of the global resources in heavy oils and oil sands bitumen, however, more than 90% of these resources need new and innovative technologies if they are to be made available at a competitive price. CANMET's Enhanced Oil Recovery (EOR) program was created in the late 1970s in response to the drive for energy self-sufficiency. Funding of the project is highly leveraged; industry funding towards projects supported under the CANMET Energy Conversion Program averaged over 300% annually since the previous review in 1990. Multi-client EOR technology projects include horizontal well technology, development of the vapour extraction process, and field testing of oil sands extraction technology. Direction and priorities of the program are established in consultation with the Minister's Advisory Council to CANMET (MNACC), industry and other performers and sponsors of enhanced oil recovery R and D. This review, including client feedback from interviews with several industry spokespersons, concluded that the program was well managed, and of high priority. Various options capable of meeting future needs were examined. Continuation of the current program, incorporating a number of significant changes, was recommended

Full Text Available The purpose of this paper was to examine to which extent the abundance and distribution of certain biological markers may be used for the identification of oil-type pollutants in recent sediments and ground waters. The samples were taken from the area of the Oil Refinery Pančevo (alluvial formation of the Danube River. The organic matter of the investigated samples was isolated using an extraction method with chloroform. The group composition and usual biological markers were analyzed in the obtained extracts. n-Alkanes and acyclic isoprenoids, pristane and phytane were analyzed using gas chromatographie (GC analysis of saturated hydrocarbons. Polycyclic alkanes of the sterane and terpane type were analyzed using gas chromatography-mass spectrometry (GC-MS, i.e. by analyzing the carbamide non-adduct of the total alkane fraction (Single Ion Monitoring SIM-technique. The obtained results indicate that n-alkanes can be used for the identification of oil-type pollutants (for example, if the oil-pollutant is biodegraded or present in very low concentrations, and steranes and triterpanes can be used as very reliable indicators of oil-type pollution in recent sediments and ground waters.

Full Text Available The prevalence of striae gravidarum (SG in pregnant women ranges from 50% to 90%. Effects of SG include itchy and hot feeling as well as dry skin. This situation also causes emotional disturbances that poses a cosmetic problem for most pregnant women. Nowadays, many pregnant women use olive oil to prevent SG, but it is relatively difficult to find and costly. In Indonesia, a similar oil, virgin coconut oil (VCO, has been used by many pregnant women for the same reason. The aim of this study was to analyze the differences and correlation between effects of olive oil and VCO against SG. The study was conducted in March−July 2012. An experimental study was performed on 80 pregnant women in Surabaya Municipality and they were divided into 2 groups using random permuted blocks. The results of this study showed that there was no difference in SG appearance based on the number of lines and levels of erythema between groups (p=0.156 and 1.00. Furthermore, there was a strong negative correlation between the effect of olive oil or VCO on the number of lines (r=-0.576 and -0.560 and the level of erythema (r=-0.699 and -0.586. In conclusion, there is no difference in the effect of olive oil and VCO against SG.

Planning international transit oil pipeline projects in Croatia

Planning and development of international oil pipeline projects are aimed primarily at enhancing the safety of crude oil supply. Pipeline development is affected by a variety of overlapping factors, such as energy - and environment-protection-related factors, as well as political, economic, legislative, social, technical and technological ones. The success of any pipeline planning, construction and operation in the present conditions will depend upon the degree to which the above factors have been brought in line with global trends. The government should create stable political, economic and legislative frameworks that will meet the global requirements of crude oil transport development. As regards (new) transportation companies, their function is to secure safe transport by providing competitive tariffs and granting environmental protection. A prerequisite for the pipeline planning is to have both major crude oil consumers and producers (as well as their economic and political integrations) consider any state or company as potential partners for crude oil transport and transit, respectively. Croatia and the JANAF transport company have been 'chosen' as one of priority routes for European supply with crude oil from the Caspian region and Russia and one of the directions for Russian crude oil export due to a number of advantages, opportunities and prospects for a successful development. Two international oil pipeline projects - the Druzba Adria Project and the Constanta-Pancevo-Omisalj-Trieste Project - are currently under consideration. The government commitment towards these projects has been documented by the Croatian Energy Development Strategy (April 2002) and by the Programme for its implementation (March 2004). JANAF has assumed the responsibility for carrying out the project preparation activities assigned to it by the Croatian Government and the pertinent ministries. Cooperation between JANAF and government institutions is an integral part of the procedure
