Uncertainty and Crude Oil Returns [PDF]

open access: possibleSSRN Electronic Journal, 2015
We use a copula approach to investigate the effect of uncertainty on crude-oil returns. Using copulas to construct multivariate distributions of time-series data permit the calculation of the dependence structure between the series independently of the marginal distributions.

THE COLLOIDAL STABILITY OF CRUDE OILS AND CRUDE OIL RESIDUES

Petroleum Science and Technology, 1999
A crude oil and three residues of the crude oil processing were investigated by determination of flocculation points of both the product solutions and the original products. Diverse analytical methods were used for characterizing products and their fractions.

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.
