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

Experimental study and modelling of asphaltene deposition on metal surfaces with superhydrophobic and low sliding angle inner coatings [PDF]
Scientific Reports, 2021 Inner coatings have emerged as a novel technique to prevent the deposition of paraffin, wax, scale, and corrosion of pipelines during oil production and transport. Few studies addressed this technique for preventing asphaltene deposition.

Effects of reservoir rock pore geometries and ultrasonic parameters on the removal of asphaltene deposition under ultrasonic waves [PDF]
Ultrasonics 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]
Scientific ReportsCO2 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 ...

Asphaltene Deposition during CO2 Flooding in Ultralow Permeability Reservoirs: A Case Study from Changqing Oil Field [PDF]
Geofluids, 2021 Asphaltene deposition is a common phenomenon during CO2 flooding in ultralow permeability reservoirs. The deposited asphaltene occupies the pore volume and decreases permeability, resulting in serious formation damage and pore well productivity.

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