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

Deep 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.

Influence of asphaltene precipitation on development effect of typical heavy oil reservoirs in eastern South China Sea

Youqi dizhi yu caishoulu
During the development of heavy oil reservoirs in the eastern South China Sea， asphaltene precipitation can cause blockages in reservoir throats， wellbores， and pipelines， leading to a decrease in the productivity of oil wells.

Terrestrial Analogs to Titan for Geophysical Research

Reviews 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 ...

Numerical Validation of Asphaltene Precipitation and Deposition during CO2 miscible flooding

Petroleum Research, 2020
Asphaltene precipitation, flocculation, and deposition can significantly reduce oil production by impacting wellbores, flowlines, and more importantly, formations’ pore space around the well.

Asphaltene Stability of Some Iraqi Dead Crude oils

Journal of Engineering, 2019
Asphaltene is one of the fractions of the crude oil which is soluble in aromatics such as benzene or toluene and insoluble in alkane such as n-heptane, n-pentane or petroleum ether (mixture of alkane compounds).

Experimental and mechanism study on the synergistic influence of asphaltene and pressure on the flow and rheological characteristics of waxy oil

Journal of Pipeline Science and Engineering
In underground reservoirs and offshore oilfields, the production and transportation of waxy oil inevitably involve pressure and asphaltene environment.

Enhancing asphaltene precipitation modeling by cubic-PR solid model using thermodynamic correlations and averaging techniques

Petroleum Science, 2019
Cubic equation-of-state solid models are one of the most widely used models to predict asphaltene precipitation behavior. Thermodynamic parameters are needed to model precipitation under different pressures and temperatures and are usually obtained ...

Deposition and removal studies of asphaltene from the glass surface [PDF]

, 2021
Asphaltene deposition in crude oil reservoirs and transportation lines affects the oil recovery and incurs additional operational costs. The current study discusses the removal of asphaltene from inorganic silica surfaces using hydrodynamic forces.
