The Effects of Oil and Gas Exploration on Greater Sage Grouse Populations

Energy production throughout the greater Rocky Mountain Region has increased dramatically in the past decade. Pristine habitat areas historically home to the greater sage grouse are being impaired by these energy development actions. Ongoing studies by state and federal biologists have shown a decrease in overall reproductive activity and a decrease in population on historical mating grounds. This project identifies actions to conserve and restore the habitat of sage grouse populations and reverse the decline of the species. Recommended measures presented in this project include using directional drilling of multiple wells from one single drill pad, creating a GIS mapping data base, funding additional scientific studies regarding impacts from energy development and improved cooperation between state, federal and private agencies.

Refinery Nonconventional Feedstocks: Influence of the Coprocessing of Vacuum Gas Oil and Low Density Polyethylene in Fluid Catalytic Cracking Unit on Full Range Gasoline Composition

Gasoline coming from refinery fluid catalytic cracking (FCC) unit is a major contributor to the total commercial grade gasoline pool. The contents of the FCC gasoline are primarily paraffins, naphthenes, olefins, aromatics, and undesirables such as sulfur and sulfur containing compounds in low quantities. The proportions of these components in the FCC gasoline invariable determine its quality as well as the performance of the associated downstream units. The increasing demand for cleaner and lighter fuels significantly influences the need not only for novel processing technologies but also for alternative refinery and petrochemical feedstocks. Current and future clean gasoline requirements include increased isoparaffins contents, reduced olefin contents, reduced aromatics, reduced benzene, and reduced sulfur contents. The present study is aimed at investigating the effect of processing an unconventional refinery feedstock, composed of blend of vacuum gas oil (VGO) and low density polyethylene (LDPE) on FCC full range gasoline yields and compositional spectrum including its paraffins, isoparaffins, olefins, napthenes, and aromatics contents distribution within a range of operating variables of temperature (500–700 °C) and catalyst-feed oil ratio (CFR 5–10) using spent equilibrium FCC Y-zeolite based catalyst in a FCC pilot plant operated at the University of Alicante’s Research Institute of Chemical Process Engineering (RICPE). The coprocessing of the oil-polymer blend led to the production of gasoline with very similar yields and compositions as those obtained from the base oil, albeit, in some cases, the contribution of the feed polymer content as well as the processing variables on the gasoline compositional spectrum were appreciated. Carbon content analysis showed a higher fraction of the C9–C12 compounds at all catalyst rates employed and for both feedstocks. The gasoline’s paraffinicity, olefinicity, and degrees of branching of the paraffins and olefins were also affected in various degrees by the scale of operating severity. In the majority of the cases, the gasoline aromatics tended toward the decrease as the reactor temperature was increased. While the paraffins and iso-paraffins gasoline contents were relatively stable at around 5 % wt, the olefin contents on the other hand generally increased with increase in the FCC reactor temperature.

Russia's best ally: The situation of the Russian oil sector and forecast for its future. OSW Study 39/2012

Oil is a strategic raw material for Russia and one of fundamental significance for the functioning of the state and its future. Taxes on oil production and exports are the most important source of state budget revenues which guarantee Russia maintains its political and economic stability. Russia is building its international position on the basis of its vast raw material and energy potential. While a great number of various publications have been devoted to Russian gas and Gazprom, surprisingly little research has been done into the present condition and possible future developments of the Russian oil sector, despite the fact that oil has and will have a much greater impact than gas on the functioning and the future of Russia. The main objective of this text is to describe the present situation of the Russian oil sector, its problems and the challenges it is posing, as well as the government’s policy towards this key branch of the Russian economy. This will be an introduction to an attempt to answer to the questions about the possible future production and the export levels of Russian oil, also broken down into the European and Asian directions.

The twilight of the oil Eldorado. How the activity of Russian oil companies on the EU market has evolved. OSW Studies 55, April 2016

The European Union has traditionally been the most important outlet for Russian oil exports. At the same time, during the period 2011-2014 a systematic decline was observed in crude oil supplies to the EU, while at the same time the export of petroleum products increased. It is now difficult to say that Russia is following a coherent oil strategy vis-a-vis the EU. The current shape of Russian activity is more the result of the business interests of individual companies, rather than the result of activities coordinated by the state. Although in the short term (up to 2020), the negative trend in crude oil exports to the EU could be halted (as confirmed by the figures for 2015), the long-term prospects for Russia's position on the EU market are pessimistic. This is because the importance of factors unfavourable to Russia is rising, such as the decrease in consumption of oil in the EU, the increased competition among exporters to the EU market, and the deterioration of the climate of Russian/EU cooperation in the context of the anti-Russian sanctions, as well as unclear prospects for the development of the upstream sector in Russia.
