Steam-solvent coinjection, if properly implemented, can improve the bitumen recovery efficiency of steam-only injection methods, such as steam-assisted gravity drainage (SAGD). Previous studies have shown that steam-solvent coinjection can reduce residual oil saturation lower than that of SAGD....

The rapid decline rates and low oil recovery factor (typically less than 10% of the original oil in place) of primary production are well-known challenges in the development of tight-oil formations. Several enhanced-oil-recovery studies and field trials have been conducted with promising results...

Solvent-steam coinjection has been proposed as an alternative to SAGD. Detailed oil recovery mechanisms of coinjection are little known due to complex interaction of phase behavior, and fluid and energy flow. This research conducts a detailed mechanistic study of phase behavior and its...

The phase behavior of reservoir fluids in tight/shale reservoirs can be dramatically altered from the bulk phase behavior due to the strong capillarity and confinement effects introduced by the confined nanopores found in the unconventional reservoirs. Therefore, an accurate description of the...

Oil sands bitumen is increasingly recovered by injecting steam into reservoirs using the energy intensive Steam assisted gravity drainage (SAGD) process. Interest in improving recovery and energy efficiencies have led to an interest in injecting light hydrocarbons along with or instead of steam...

Ahitan, Sourabh

Global phase behavior calculations based on 150 n-alkane + aromatic and n-alkane + naphthenic hydrocarbon binary mixtures were performed. These calculations were compared with experimental measurements whenever possible, and additional measurements were made as part of this work. The widely used...

Unwanted phase separation of asphaltenes poses significant challenges in production and processing of heavy oils and bitumen. The analysis and prediction of asphaltene precipitation behaviors and asphaltene-diluent interactions are typically treated either from a solution thermodynamics or a...

The main objective of this research was to exploit the interrelations between the rheological behavior and nano-microstructure of complex fluids in solving two state-of-the-art problems, one in the field of biomedical engineering: controlling the amount and characteristics of bioaerosol droplets...

The main objective of this research is to determine if expanding solvent-steam assisted gravity drainage (ES-SAGD), wherein a small quantity of a condensable solvent is coinjected with steam, can be a better alternative to SAGD in highly heterogeneous formations. Specifically, three previously...
