.... The significant HDN and HDS removal coupled with decreased viscosity, increased °API value, and light hydrocarbons indicate upgrading of the original Athabasca bitumen for all three tests. The results showed that although the regenerated catalyst Tests 2 and 3 lost HDN activity compared to the fresh catalyst...

...Kirk Duval; Dubert Gutiérrez; Dino Petrakos; Pierre Ollier; Darren Johannson Summary The Pelican Lake field in northern Alberta (Canada) is home to the first successful commercial application of polymer flooding in higher-viscosity oils (i.e., greater than 1,000 cp), which has opened up new...

... days) at different air-flow rates and at temperatures of 5, 15, and 25C. The solvent content, density, and viscosity of the films were measured after different weathering times. A second set of tests at 15C was performed on both dilbit and light-crudeoil films on water. As expected, the mass-transfer...

...Mohammad Kariznovi; Hossein Nourozieh; Jalal Abedi The heavy-oil- and bitumen-recovery processes mainly intend to reduce the oil viscosity at the reservoir; therefore, the production and pipeline transportation of such viscous fluids require specific data on the viscosity and density of raw bitumen...

.... Velocity of the falling barite bed is calculated on the basis of an apparent viscosity approximated by the experiments. Knowing the velocity of the moving bed, the mass rate of barite downstream of the bed, which goes back into the main flow stream, is calculated and a new density for the moving fluid...
