Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Asphaltene is a solid oil component with a wide range of molecular compositions and
structures, making it one of oil's most complicated components. The deposition and …

Heavy crude oils and bitumen represent more than 50% of all hydrocarbons available on the
planet. These feedstocks have a low amount of distillable material and high level of …

Asphaltene deposition in porous media has a destructive effect on well productivity during
primary and secondary oil recovery. Previous research studies have presented models for …

CO 2 injection is a well-known and highly efficient enhanced oil recovery (EOR) technique.
In this method, undesirable asphaltene precipitation and deposition may occur at upstream …

Physical and numerical simulations of subsurface upgrading using solvent deasphalting
(SSU-SDA) at laboratory conditions will be presented using a heavy crude oil and propane …

Asphaltene deposition in porous media could reduce permeability up to 90%. Nonetheless,
this would occur often for a slight reduction in porosity. This, in turn, indicates that while the …

Physical and numerical simulations of subsurface upgrading by use of solvent deasphalting
(SSU-SDA) at laboratory conditions will be presented with a heavy crude oil and propane as …

Carbon dioxide (CO₂) injection in oil reservoirs is a potential means of Enhanced Oil
Recovery (EOR) and reducing greenhouse gas. Change in the thermodynamic condition …

The most important issue is the right management of hydrocarbon reservoirs, and knowing
the effects of different factors related to the amount of oil recovery. The formation of …
