Evaluation of rock and fluid intermolecular interaction between asphaltene and sand minerals using electrochemical, analytical spectroscopy and microscopy techniques

Scientific Reports
Long-time contact of heavy crude oil with rock leads to an adsorption phenomenon, which causes the rock surface to become oil-wet and appears as a barrier to the fluid flow in the porous media.

EFFECT OF INHIBITORS ON ASPHALTENE PRECIPITATION [PDF]

, 2013
Asphaltene precipitation and its deposition along the production system and separation facilities cause a lot of problems in the Oil and Gas industry. It damages reservoir by reducing its permeability while also changing its wettability.

A novel inhibitor for controlling Iraqi asphaltene problems [PDF]

, 2017
Asphaltene precipitation plays a key role in many flow assurance problems like fouling in production facilities, pipelines and refineries. Several attempts have been made to stabilize the asphaltene and prevent its precipitation by using asphaltene ...

Prediction of the Gas Injection Effect on the Asphaltene Phase Envelope

Oil & Gas Science and Technology, 2015
Asphaltene instability may occur when pressure, temperature and compositional variations affect the reservoir oil. Permeability reduction, wettability alteration, and plugging of wells and flow lines are the consequences of this phenomenon. Therefore, it

Investigation of Asphaltene Stability in the Iranian Crude Oils [PDF]

Iranian Journal of Chemical Engineering, 2008
The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies and structural characterization of resins and asphaltenes were carried out in order to study a possible relationship between ...

Research Progress in Nanoparticle Inhibitors for Crude Oil Asphaltene Deposition

Molecules
Currently, the alteration of external factors during crude oil extraction easily disrupts the thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and deposition of asphaltene molecules in crude oil.
