Due to the growing global energy demand and increasingly limited availability of
conventional or easy-to-produce crude oils, extensive attention is being paid to the …

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 …

CO 2 foam is a promising candidate in enhanced oil recovery and reducing anthropogenic
CO 2 emission through geo-sequestration due to its CO 2 mobility control ability. However …

Oil reserves of the thin heavy oil reservoirs are estimated to be over 400 billion barrels. The
recovery factor of water-flooding in these reservoirs is as low as 10–20% due to the high oil …

Multi-component supercritical thermal fluid (MCSCTF) can be used to efficiently extract
highly viscous heavy oil. However, few works have been conducted to explore MCSCTF …

A novel water-soluble viscosity reducer system based on polycyclic aromatic hydrocarbon
(PAH) was designed and synthesized for heavy oil viscosity reduction and enhanced heavy …

Heavy oil reserves comprise more than 60% of global crude oil resources, and thermal oil
recovery techniques, especially steam injection, are widely utilized for extracting heavy oil …

Ultradispersed particles of a size less than 100 nm for in situ catalytic upgrading have been
reported to outperform the augmented catalytic upgrading achieved by incorporating …

The sufficient energy to transfer the crude oil to the surficial wellbore facilities would be
reduced dramatically which was done by CO 2, especially for heavy and super-heavy oil …

As an industrial waste gas, flue gas achieves a favorable performance in assisting steam to
develop heavy oil, where steam distillation plays a crucial role. However, there are few …
