In Situ Heavy Oil Upgrading Through Ultra-disperse Nano-Catalyst Injection in Naturally Fracture Reservoirs
… the next challenge for maintaining the world’s oil production. Several EOR processes are under study, one promising is the “In Situ Upgrading” which produces EOR and Upgrading by injection of a hot fluid, in this case vacuum residue from the heavy oil produced, with suspended nano-catalytic …

Multi-scale modeling tools for coupled reaction, phase equilibrium and two-phase mixing phenomena with application to supercritical water heavy oil upgrading process
Supercritical water heavy oil upgrading, which has the potential for high distillate liquid yields with lower coke formation, is a complex process involving coupled reactions, phase equilibrium and two-phase mixing phenomena. This thesis presents the development of a range of models and tools to …

In-Situ Upgrading and Recovery Enhancement of Athabasca Bitumen by Ultra-Dispersed Nanocatalysts
Thermal methods are extensively used to extract heavy oil and bitumen with reasonable recovery percentages to compensate for the light oil production decline in recent years. In addition, new technologies are tested to increase the value of the produced liquids. Nanoparticles technology is emerging …

Reactor Design for Partial Upgrading of Bitumen via Aquaprocessing
Alberta oil industry is facing a major challenge because of the widening price differentials between West Texas Intermediate and Western Canadian Select. The Western Canadian Select is trading at low of US$ 16.71 /bbl. because of its high viscosity, density, total acid number, and sulfur content …
