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 …

Steam injection is widely used as an enhanced oil recovery method for heavy oil fields;
however, its efficiency normally decreases in late injection stages. Recent studies have …

This paper evaluates and analyzes three decades of ongoing SAGD projects in Canada,
examining their successes, failures, lessons learned, and limitations from multiple …

There are serious problems such as steam channeling and low oil-steam ratio when it
comes to steam flooding. In order to improve its performance and to enhance oil recovery …
