Effect of Asphaltenes and Asphaltene Dispersants on Wax Precipitation and Treatment
Colloids and InterfacesA detailed understanding of the interactions between wax and asphaltenes with other components of crude oils and the effect of treatments with paraffin inhibitors (PIs) and asphaltene dispersants (ADs), with a focus on identifying specific structure-activity relationships, is necessary to develop effective flow assurance strategies.

Probing the surface of synthetic opals with the vanadyl-containing crude oil by using EPR and ENDOR techniques [PDF]
Magnetic Resonance in Solids 21, 19101 (2019), 2019 Porous silica materials offer wide range of possibilities for enhancement of the productivity of oil reservoirs. However the mechanism of adsorption of polar components of crude oil on silica surface is poorly understood that hinders technological improvement of supports and oil extraction.
