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 deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

The permeability reduction associated with asphaltene precipitation and deposition in gas
injection EOR processes has been widely observed and well-studied in conventional plays …

One of the challenges in extracting oil from unconventional resources using hydraulic
fracturing and horizontal drilling techniques is the low primary recovery rate, which is caused …

Asphaltene precipitation and deposition in the reservoir, near-wellbore region, and pipelines
is one of the critical problems in flow assurance. It can cause a blockage of pore throats and …

The existing theoretical and empirical models to describe asphaltene deposition in porous
media do not consider the complicated structure of pore network. Permeability reduction due …

Cyclic gas injection methods have been shown to improve oil recovery in conventional
reservoirs. Even though similar technologies have been used in unconventional reservoirs …

In this work, asphaltene adsorption in a sandstone core sample under dynamic conditions
and during miscible CO 2 injection was studied using live oil sample which is close to real …

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 …

Understanding the colloidal structure of crude oil in pipeline is of great significance for
finding effective solutions to remediate and prevent the aggregation and deposition of …
