Research Progress in Nanoparticle Inhibitors for Crude Oil Asphaltene Deposition [PDF]

open access: yesMolecules
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.

Effects of reservoir rock pore geometries and ultrasonic parameters on the removal of asphaltene deposition under ultrasonic waves [PDF]

open access: yesUltrasonics Sonochemistry, 2022
Asphaltene deposition around the wellbore is a major cause of formation damage, especially in heavy oil reservoirs Ultrasonic stimulation, rather than chemical injection, is thought to be a more cost-effective and environmentally friendly means of ...

Characterization of asphaltene deposition and formation damage during CO2 miscible/immiscible flooding in Low-permeability sandstones using NMR T 1-T 2 [PDF]

open access: yesScientific Reports
CO2 flooding in low-permeability oilfields has been widely adopted worldwide as it significantly enhances oil recovery. However, when CO2 is injected into the reservoir, asphaltene precipitation may occur, damaging the reservoir and resulting in a less ...

NUMERICAL MODELING OF ASPHALTENE DEPOSITION [PDF]

open access: yesComputational Thermal Sciences, 2013
Asphaltene deposition on the walls of wellbore or pipeline during oil production and processing will cause dire consequences if left untreated. A better understanding of this phenomenon is required. This study presents a general modelling framework based either on the level-set approach or the concentration approach for modelling asphaltene deposition ...

Impact of various aggregation kinetics on thermophoretic velocity of asphaltene deposition [PDF]

open access: yesScientific Reports
Asphaltene deposition may pose serious challenges to flow assurance of crude oil in well columns. Different aggregation kinetics would partly be responsible for asphaltene particle growth ending in deposition on the surface of well columns.

Asphaltene deposition effects on reservoir rock wettability and modification strategies [PDF]

open access: yesHeliyon
Asphaltene deposition, a widespread challenge in the petroleum industry, detrimentally affects oil production, transport, and processing. Our study investigates asphaltene's impact on sandstone and carbonate reservoir rock wettability using ASTM-D6560 ...

A Novel Method for Mitigation of Asphaltene Deposition in the Wellstring [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
Asphaltene precipitation and deposition is a serious problem in many Iranian fields. The deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production.

Lubricant-Impregnated Surfaces for Mitigating Asphaltene Deposition [PDF]

open access: yesACS Applied Materials & Interfaces, 2020
Asphaltenes are heavy aromatic components of crude oil. Their complex chemical makeup-an aromatic core surrounded by aliphatic side chains-enables them to adhere to most surfaces. Their buildup in pipes can result in clogging and lead to interruption of production operations and expensive mechanical cleaning.
