Analysts have likened the growing direct state role in Kazakhstan’s petroleum sector since 2002 to a form of ―resource nationalism‖ that is part of a global trend precipitated by high oil prices. This interpretation has obvious appeal, both in light of earlier periods in which waves of nationalization coincided with oil price booms and the recent socalled ―re-nationalizations‖ in Bolivia, Venez...

Fuel ethanol is one of the technology success stories of the 21 century. In less than one third of a century, it has gone from being a material produced rather inefficiently in small quantities to a major commercial product. This success can be attributed not only to the fact that ethanol is a renewable fuel and replaces imported oil, but also because it is capable of competing with petroleum b...

We use high-frequency intra-day realized volatility to evaluate the relative forecasting performance of several models for the volatility of crude oil daily spot returns. Our objective is to evaluate the predictive ability of time-invariant and Markov switching GARCH models over different horizons. Using Carasco, Hu and Ploberger (2014) test for regime switching in the mean and variance of the ...

Crude oil separation processes involve many high profile control systems and equipment that costing a vast amount of investment. Any mistake in the management will cause serious aftermath. The main focuses in this paper are the design of simulation modelling of an oil production area and is used as planning, controlling and decision making tool with associated factors such as crude oil input ra...

The haematological effects following ingestion of shellfish exposed to crude oil polluted water or the pollutant perse were investigated in albino Wistar rats. Feeding of four groups of rats for 28 days duration with two reference casein or shellfish protein control diets (Group A and B), and two test diets (Group C and D) supplemented at varying levels with shellfish which had been previously ...

Dispersants are a preapproved chemical response agent for oil spills off portions of the U.S. coastline, including the Texas-Louisiana coast. However, questions persist regarding potential environmental risks of dispersant applications in nearshore regions (within three nautical miles of the shoreline) that support dense populations of marine organisms and are prone to spills resulting from hum...

Previous economic analyses focused on relationships between crude oil and natural gas markets centered primarily on demand-side considerations. We provide evidence that two important supply-side connections play important roles in understanding crude oil and natural gas market integration. First, crude oil production and natural gas production require a common capital input: rotary drilling rig...

in general, energy prices, such as those of crude oil, are affected by deterministic events such as seasonal changes as well as non-deterministic events such as geopolitical events. it is the non-deterministic events which cause the prices to vary randomly and makes price prediction a difficult task. one could argue that these random changes act like noise which effects the deterministic variat...

Production and spillage of petroleum hydrocarbons which is the most versatile energy resource causes disastrous environmental pollution. Elevated oil degrading performance from microorganisms is demanded for successful microbial remediation of those toxic pollutants. The employment of biosurfactant-producing and hydrocarbon-utilizing microbes enhances the effectiveness of bioremediation as bios...
