Studies that investigate and attempt to model the process of steam‐assisted gravity drainage
(SAGD) for heavy‐oil extraction often adopt the single‐phase‐flow assumption or relative …

Steam assisted gravity drainage (SAGD), as a commercially proven high ultimate recovery
process for heavy oil and bitumen is energy intensive and may be limited by high usage of …

Solvent‐aided thermal recovery processes have recently gained practical and research
interests among other thermal recovery methods due to their reduced environmental …

Unconventional oil, irrespective of whether it is a bio-oil, coal oil, petroleum oil, or waste oil,
is an oil that is too viscous to effectively transport in its native state. Processing of …

Steam/solvent coinjection has been studied and pilot tested as a potential method to
improve steam-assisted gravity drainage (SAGD) for bitumen recovery. Reliable design of …

Bitumen residues in oil sand tailings ponds create greenhouse gas emissions and threaten
the ecosystem. However, it is technically challenging to recover bitumen residues from …

Thermal treatment of oil sand bitumen froth has the goal of not only improving the separation
process during froth treatment but also accomplishing bitumen upgrading. There is evidence …

Solvent deasphalting and visbreaking are two important technologies in the development of
processes for partial upgrading of oilsands-derived bitumen to improve oil fluidity for …

A solvent-based thermal recovery process has the advantages of low capital expenditure,
