In the late stages of Steam Assisted Gravity Drainage (SAGD) development, the increase in
steam chamber volume and greater heat losses result in elevated thermal losses, and …

Bitumen transportation by pipelines requires dilution with solvents. These diluents are often
expensive. Therefore, the utilization of liquid CO 2 as a diluent to reduce or eliminate diluent …

The primary bottleneck in heavy oil production lies in the significant energy consumption
and CO 2 emissions associated with steam injection for recovery. To address this challenge …

In this work, a unified, consistent, and efficient framework has been proposed to better
predict the density of a gas (es)-heavy oil/bitumen system by using the Peng-Robinson …

The production of heavy oil and bitumen is more complex and expensive than conventional
oils. One of the main reasons is that heavy oils and bitumen have high viscosity and are …

The main recovery mechanism in the solvent-based bitumen recovery processes is gravity
drainage. The density of heated bitumen or diluted bitumen at operational conditions is …

Solubility of light n‐alkanes in bitumen as well as density and viscosity of the bitumen‐rich
phase are the necessary data for simulation and study of the solvent‐aided thermal recovery …

In this study, a new and pragmatic methodology has been developed to accurately predict
the viscosity for light solvents (ie, methane, ethane, propane, n-butane, n-pentane, N2, and …

Solvent-aided or solvent-based heavy oil recovery methods have shown to be promising
alternatives to the conventional thermal methods. Recently, dimethyl ether (DME) has been …

The gravity drainage as a result of viscosity reduction is the main governing mechanism of
the solvent‐aided thermal bitumen recovery processes. Therefore, the density and viscosity …
