This paper describes a foamed cement solution designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta.

This paper describes the potential, challenges, and opportunities of using a modified steam-assisted gravity drainage configuration in the Mukhaizna heavy oil field in suboptimal operating conditions.

This study aims at understanding the effect of a surfactant known as a high-temperature emulsifying agent as an additive to the steam-assisted gravity drainage process and the possibility of forming oil-in-water emulsions.

The objective of this paper is to present a fundamentals-based model of three-phase flow consistent with observation that avoids the pitfalls of conventional models such as Stone II or Baker’s three-phase permeability models.

The objective of this study is to conduct a comprehensive review of the latest technologies and work flows developed for heavy oil reservoir management.

The paper presents successful field tests designed to decrease electrical-submersible-pump cooling rates by inducing controlled deadheads rather than shutting down the pumps.

In-situ extraction of heavily sulfured oil by use of steam injection comes with a high risk of hydrogen-sulfide production resulting from aquathermolysis reactions. This could lead to casualties, environment damage, and corrosion of surface facilities and wells. Also, a strong need exists to understand aquathermolysis reactions and to forecast the generation of acid g…

This paper describes the findings of a root-cause analysis of wellhead-penetrator failures in Canadian steam-assisted gravity-drainage operations and the mitigation measures taken.

Oil sands producers predicted they could reduce production by 300,000 B/D by turning down steam injection. This will test methods to reduce, rather than stop, injection to avoid the damage caused by rapid cooling in some wells.

When oil demand vaporized, oil sands producers cut 300,000 B/D of production from wells using steam injection to produce bitumen. It is a huge test of something they have long been reluctant to do—turn down in-situ production when prices plunge.
