The efficiency improvement of steam injection (more oil, less steam) is a critical challenge in
heavy oil recovery. Using chemical additives is one option to achieve this efficiency …

Heavy-oil is and will be an essential part of energy supply. The most common and practical
way of producing any type of heavy-oil is steam injection; although this technique is both …

Steam injection has been proven to be a technically reliable and economically successful
heavy oil recovery technique. However, the large amount of energy that is required to …

In this paper, the interfacial properties of a rock/heavy-oil/steam system were measured to
observe the degree of wettability alteration when adding new generation chemicals to steam …

Steam injection has been widely applied in different forms to recover heavy-oil and bitumen
for decades. Even though this method is a proven and effective technology, the steam …

Our previous research, honoring interfacial properties, revealed that the wettability state is
predominantly caused by phase change—transforming liquid phase to steam phase—with …

There are a plethora of factors that may impact the viscous finger profiles observed in heavy
oil-in-water emulsification in porous media such as chemical properties, chemical reaction …

In view of the serious heat loss in the process of steam injection for heavy oil recovery,
nonhydrocarbon gas combined with steam has attracted much attention in recent years to …

Interlayer heterogeneity, an inevitable and complex challenge during water flooding,
seriously constrains the spread of the sweep region and oil recovery enhancement in …

Understanding fingering, as a challenge to stable displacement during the immiscible flow,
has become a crucial phenomenon for geological carbon sequestration, enhanced oil …
