In this article, the importance of colloids and interfaces in thermal heavy oil or bitumen
extraction methods is reviewed, with particular relevance to oil sands. It begins with a brief …

The combination forms of the hydrate dissociation methods in different well systems are
divided into 6 main patterns. Dissociation processes of methane hydrate in porous media …

After a cyclic steam stimulation (CSS) process achieved accidental success in recovering
heavy oil resources in the 1960s, thermal recovery processes started to unlock the door of in …

Steam solvent co-injection processes are generating considerable interest in terms of
improving heavy oil upgrading in unconventional reservoirs. The characteristics of the opted …

Abstract Steam Assisted Gravity Drainage (SAGD) is a thermal recovery technology currently
employed to extract heavy oil and high viscosity bitumen from Alberta oil sands. Due to the …

The technical aspects of steam-assisted gravity drainage (SAGD), as a thermal recovery
method, are thoroughly reviewed. SAGD is a commercial process with many successful …

The effect of coinjection of hydrocarbon solvents (C4, C5, C6, C7, and C8), with steam at low
pressure, on heavy oil recovery is addressed. It is concluded that the coinjection of solvents …

Gas mobility control is highly required to obtain a sufficiently-expanded and uniformly-
developed steam chamber, which is conducive to steam-assisted gravity drainage (SAGD) …

ABSTRACT A new process for ultrasonic-assisted surfactant extraction of bitumen from
Buton oil sands is performed. The microstructure and composition of Buton oil sands are …

ABSTRACT The 2019 Critical Review by Brook et al.(2019) summarized much work by
Environment and Climate Change Canada (ECCC), but discussants in Altshuler et al.(2019) …
