Crude Oil Price Determinants [PDF]

open access: possible, 2007
Based on monthly observations, I specify an econometric model capturing the driving forces behind the crude oil price series in recent years. A large set of covariates, such as supply and demand variables as well as futures market variables, is used to test the impact on the crude oil price.

Biodegradation of Crude Oils

1991
Petroleum from well sites in the Gifhorn Trough (Lower Saxony, NW-Germany) and the Maracaibo Basin (Venezuela) contained various types of microorganisms capable of degrading crude oils. Genetically related oils were inoculated with the isolated microorganisms and the degradation of the oils was followed by chromatographic techniques.

Bioinspired Solar‐Heated Carbon Absorbent for Efficient Cleanup of Highly Viscous Crude Oil

Advanced Functional Materials, 2019
Efficient cleanup of viscous crude oil spill is a worldwide challenge due to its sluggish flowability at room temperature. Conventional oil remediation methods using physical absorbers, skimmers, and vacuum technologies either demonstrate low absorption ...

Egg Shell Powders-Coated Membrane for Surfactant-Stabilized Crude Oil-in-Water Emulsions Efficient Separation

ACS Sustainable Chemistry and Engineering, 2019
Low-cost, environmentally friendly superwetting materials are urgently desired in industrial oily wastewater situations. In our work, egg shell powders (ESP)-coated polyvinylidene fluoride (PVDF) membranes were fabricated by vacuum pumping ESP and sodium

Characterizing Crude Oil Toxicity to Early-Life Stage Fish Based On a Complex Mixture: Are We Making Unsupported Assumptions?

Environmental Science and Technology, 2019
Numerous studies of the water-soluble fraction (WSF) from crude oil have concluded that polycyclic aromatic hydrocarbons (PAHs) are the primary causative agents for early life stage (ELS) fish toxicity.

Impact of Natural Surfactant (Reetha), Polymer (Xanthan Gum), and Silica Nanoparticles To Enhance Heavy Crude Oil Recovery

Energy & Fuels, 2019
The recovery of heavy crude oil is limited because of the high interfacial tension (IFT) between the crude oil and aqueous phase, which restricts the extent of emulsification and results in poor mobility.
