The in-situ steam-based technology is still the main exploitation method for heavy oil and
oilsands resources all over the world. But currently most of the steam-based processes (eg …

Due to the increased demand for energy resources these days, especially due to the
Russian-Ukrainian war, the focus of the major countries is turning strongly towards …

The use of water in hydrothermal and supercritical conditions as a medium to upgrade
heavy oil fractions has shown promising results and presents an interesting alternative for …

Water flooding has been accepted as the first-hand strategy for oil recovery as well as for
unconventional oil reservoir development. However, a large amount of heavy oil is generally …

Laboratory and field data, although limited in number, have shown that steam/solvent
coinjection can lead to a higher oil-production rate, higher ultimate oil recovery, and lower …

Asphaltene and resin are polar compounds that have a high potential to absorb microwaves.
Irradiation frequency is one of the important factors in increasing the efficiency of this …

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 …

We present results of a detailed investigation of the steam/solvent-coinjection-process
mechanism by use of a numerical model with homogeneous reservoir properties and …

Solvent-steam processes gained popularity in recent years in the extraction of high-
asphaltenes-content heavy hydrocarbons. However, while solvent selection is key for the …

Abstract Non-condensable gas (NCG), foam and surfactant are the three commonly-used
additives in hybrid steam− chemical processes for heavy oil reservoirs. Their application can …
