dc.description.abstract97% of Canadian oil reserves are oil sands, with 80% in undeveloped in-situ reservoirs. Knowledge of the density, viscosity and mutual solubility of bitumen and bitumen/water mixtures greatly improves the exploitation of these reservoirs that require thermal recovery techniques. Determining these parameters is challenging due to the high temperatures and pressures of these reservoirs. This work utilizes a variable-volume bellows cell with a custom viscometer to measure density and viscosity for a Christina Lake bitumen and Christina Lake bitumen/water mixtures at 13.8 MPa (2000 psig) up to 300⁰C. Mutual solubility and composition is determined from samples using Karl Fischer titration and Dean Stark distillation. Results indicate that density and viscosity decrease significantly with increasing temperature up to 300⁰C. Mutual solubility results were inconclusive due to apparatus malfunctions. Thermal cracking at 300⁰C was evidenced by a change in the oil density and viscosity at lower temperatures and was more significant in the presence of water.en_US
