Effects of oil and oil burn residues on seabird feathers [PDF]

open access: yesMarine Pollution Bulletin, 2016
It is well known, that in case of oil spill, seabirds are among the groups of animals most vulnerable. Even small amounts of oil can have lethal effects by destroying the waterproofing of their plumage, leading to loss of insulation and buoyancy. In the Arctic these impacts are intensified.

Investigation on influences of polymer solution properties on stress distribution and deformation of residual oil

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
After water flooding, there is much residual oil left in the pores. This cannot be easily displaced, but polymer flooding is able to achieve this. The use of viscoelastic solutions such as polymer can enhance the oil recovery, because it can increase the
