... porosity. Water is known as a good absorber for EM waves, thus, pore space were saturated at different water saturations and a bitumen sample (10,000 cP, 12° API) from Canada. Prepared samples were packed into in-house-built-Plexiglas core holder which allows measurements with EM waves. The response of EM...

... Abstract Since decades, steam-assisted oil recovery processes have been successfully deployed in heavy oil reservoirs to extract bitumen/heavy oil. Current resource allocation practices mostly involve reservoir model-based open loop optimization at the planning stage and its periodic recurrence...

... Abstract Warm solvent injection (WSI) has been proposed as a promising alternative to steam-based methods for bitumen recovery, due to its potential to reduce greenhouse gas emissions and environmental footprint. It involves injecting heated vaporized solvent (low molecular weight hydrocarbons...

... Abstract The objective of this study is to examine the impact of polarity on surfactant-steam flooding performance in the recovery of a Canadian bitumen sample. 10 laboratory-scale core flood experiments were used to investigate the interaction between the polar head of surfactants and polar...

In order to effectively mobilize bitumen, bond scission reactions are required to occur between the injected oxygen and the bitumen. The highly effective combustion process is accompanied by thermal...
