... grid block used in the simulation of VAPEX. This is adequate when very fine grid blocks are chosen to simulate the process where the boundary layer (transition zone) occurs over a number of grid blocks. Fine grid blocks, however, require a large amount of simulation time, which is not applicable...

.... In cases where unstructured grids are used or the geology inside the grid block is not aligned with the block geometry, full permeability tensors arise instead of a diagonal tensor. The focus of this work is on development of a method to characterize the full permeability tensor for an unstructured grid...

... that lead to steep reaction front. Such sharp reaction fronts are difficult to capture using traditional numerical schemes unless by means of very fine grid numerical simulations. Fine grid simulations of such reactions at large scale are computationally expensive. On the other hand, using coarse grid block...

A 3-D thermal numerical simulator was used to investigate the accuracy of the numerically calculated swept volume with the analytically estimated swept volume in SAGD process. In addition, a number of parameters, such as grid blocks...

... in the computational hardware or modification to the way the simulation is done is, therefore, necessary. A typical grid block size is 100 m areally and 1–10 m vertically. Such a large grid block may include a lot of heterogeneity. If we use rock curve for simulation with such large grid blocks, the important effects...
