Green dispersants are so-called “green” because they are renewable (from bio-based
sources), non-volatile (from ionic liquids), or are from naturally available solvents (vegetable …

Due to superior surface activity and physicochemical properties, ionic liquids (ILs) have
been applied in petroleum industry in different ways, such as ILs-assisted solvent extraction …

Water-and solvent-based ex situ extraction processes have been employed to extract
bitumen from mineable oil sands. On the other hand, bitumen is recovered in situ from …

This paper examines the transformation of heavy oil composition in porous media of
carbonate reservoir rocks under hydrothermal processes in the presence of transition metal …

Hydraulic fracturing has long been an established well stimulation technique in the oil & gas
industry, unlocking hydrocarbon reserves in tight and unconventional reservoirs. The two …

Highlights Two Aspergillus isolates from bitumen grow well on extra-heavy crude oil.
Extracellular enzymes of both fungi efficiently degrade extra-heavy oil fractions …

During the steam flooding of extra heavy oil, expansion of steam chamber is difficult and
erosion channels appear, which is different from conventional heavy oil. The …

Water retention curve essentially determined by pore throat morphology, wettability, pore
connectivity and so on has a close relationship with many physical properties of hydrate …
