Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 2, Page 556-566, June 2026.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Asphaltene Removal – The Effect of Ionic Liquid to Asphaltene Characteristics [PDF]

open access: yes, 2009
Crude oil composes of asphaltene, along with saturates, aromatics and resins (SARA) compound. Changes of temperature and pressure during oil production lead to the precipitation, flocculation and aggregation of asphaltene.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Molecular Dynamics Simulation of Self-Aggregation of Asphaltenes at an Oil/Water Interface: Formation and Destruction of the Asphaltene Protective Film

open access: yes, 2014
It is well known that asphaltene molecules play a significant role in stabilizing emulsions of water in crude oil or diluted bitumen solutions: Molecular dynamics simulations were employed to investigate the aggregation anti orientation behaviors of ...

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Experimental Investigation of Asphaltene Induced Permeability Reduction

open access: yes, 2010
CO2 injection is one of efficient enhanced oil recovery (EOR) methods among gas flooding, however, asphaltene precipitation during CO2 injection might lead to production loss and reduced efficiency. To understand the mechanism of asphaltene deposition is
