Heavy oil resources have become increasingly important in recent years due to a reduction
in light oil production and an increase in energy consumption. A large number of heavy oil …

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 …

The dynamic oil-CO 2 mixing and miscible flow in porous media are complex and important
phenomena that occurs during CO 2 injection for enhanced oil recovery (EOR) and …

CO 2 emissions tend to increase more rapidly in underdeveloped economies as compared
to developed countries mainly in China, India, and Asia. One of the aspects that accounts for …

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 …

A generalized methodology has been developed to determine the diffusion coefficients of
supercritical CO 2 under tight oil reservoir conditions considering the oil swelling effect …

In this research, experimental and mathematical modeling studies were implemented to
determine the CO 2 diffusion coefficients in bulk phase (nontransparent high-pressure cell) …

Our understanding of EOR processes in shales, especially in organic or kerogen pore
systems, has grown rapidly over the last few years. While clays are ubiquitous in shales and …

To accurately predict saturation pressures for gas (es)-heavy oil/bitumen-water systems,
several α functions have been selected and evaluated at a reduced temperature (Tr) of 0.70 …

Fluid immobilizations in tight formations augment the importance of CO 2 molecular
diffusions in the processes of geological carbon utilization and storage. This study, for the …
