Carbon dioxide (CO 2) enhanced oil recovery (EOR) in carbonate reservoirs is regarded as
a promising EOR technology. However, the oil recovery factor of CO 2 EOR is low due to the …

CO2 molecular diffusion in subsurface porous media is one of the key mechanisms in high-
pressure–high-temperature CO2 geosequestration and CO2-based enhanced oil recovery …

Polymeric nanoparticle (NP) suspensions are colloidal suspensions where NPs (size≤ 100
nm) are suspended in the polymer-enhanced base fluid, mainly water. Compared to water or …

Unit operations and processes abound with gas diffusion in liquids, which is a sophisticated
phenomenon in which mass transfer is characterized by diffusion coefficient or diffusivity …

The present work reports Fick diffusion coefficients D 11 in the saturated liquid phases of
binary mixtures of cyclohexane, n-hexadecane, n-octacosane, or n-hexanoic acid and …

In this paper, two sandstone cores with permeabilities of 1.7 mD and 2.6 mD were employed
and the ScCO 2 huff-n-puff processes were carried out to check the oil recovery efficiency as …

CO 2 diffusion is of great importance for enhanced oil recovery (EOR), production prediction,
and performance forecast of carbon capture and storage (CCS) in shale reservoirs. This …

In this paper, extraheavy oil recovery assisted by CO 2 and an oil-soluble viscosity reducer
under deep reservoir conditions was experimentally investigated. Specifically, the viscosity …

By performing dynamic volume analysis, we developed and applied an experimental and
theoretical technique to determine mutual diffusivity (ie, diffusivity of a gas component in an …

To reveal the enhanced oil recovery (EOR) potential of CO 2 huff-n-puff in fractured tight
conglomerate reservoirs, hydraulic fracturing combined with CO 2 huff-n-puff experiments …
