However, simulation can be extremely time consuming. Computer resources and man power constraints can often limit the areal...

... of bitumen from Athabasca oil sands in Alberta, Canada. This paper describes the numerical simulation of this experiment. The objective was to demonstrate the capability of the numerical model to capture the significant mechanisms of the steam-surfactant-nitrogen drive process conducted in the 90 cm physical...

... reservoir volume. This paper presents numerical simulation results of such a process for Alaskan tar sand reservoirs using a horizontal well simulator. Numerical simulation resulls show oil recovery as high as 40% of the oil in place for tar sands. The recovery is even higher for heavy oil of moderate...
