Microbial enhanced oil recovery (MEOR) depends on the in situ microbial activity to release trapped oil in reservoirs. In practice, undesired consumption is a universal phenomenon but cannot be observed effectively in small-scale physical simulations due t ...
Being able to estimate the partitioning behavior of the live oil mixture between a gas and a hydrocarbon liquid phase is crucial for valid modeling of the behavior of the emitted fluid. Equations of state are a well-known way to estimate the phase partitio ...
In recent years, the independent measurement of wall shear stress with oil-film or oil-drop interferometry has become a cornerstone of turbulent-boundary-layer research as many arguments depend critically on a precise knowledge of the skin friction tau(w)* ...
During the first hours after release of petroleum at sea, crude oil hydrocarbons partition rapidly into air and water. However limited information is available about very early evaporation and dissolution processes. We report on the composition of the oil ...
Important properties of a crude oil, such as viscosity, are determined by the crude oil's chemical constituents. In particular, viscosity is highly dependent on the asphaltene content. Various processes that act on reservoir crude oils can alter chemical c ...
Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...
We develop and use a circulation model to estimate hydrographical and ecological changes in the isolated basin water of the Bornholm Basin. By pumping well-oxygenated so-called winter water to the greatest depth, where it is forced to mix with the resident ...
Biodegradation plays a major role in the natural attenuation of oil spills. However, limited information is available about biodegradation of different saturated hydrocarbon classes in surface environments, despite that oils are composed mostly of saturate ...
Following the release of crude oil from the Macondo well in 2010, a wide range of weathering processes acted on the spilled oil. A recent study revealed that samples from this spill were oxidized into oxygenated hydrocarbons (OxHC) comprising more than 50% ...
Anthropogenic releases of petroleum fluids, which contain thousands of compounds, represent a threat to marine environments. However, there was a lack of models able to explain the independent behaviors of the numerous compounds of a spilled petroleum flui ...
