Different influencing factors in the process of polymer flooding have different degrees influence on development effect, so it is necessary to carry out dynamic prediction before implementing scheme. In this study, reservoir model C Block established and production performance fitted. The fitted used study concentration, injection time, rate multiple timing effect Block. results show that cumul...

The effective permeability of dual-structured porous media has been determined through physical and numerical modeling. Example porous media consisting of a woven network of cylindrical bars overlaid by a network of spherical particles have been produced by a rapid prototyping technique. A glycerin-based solution, held in a pressurized reservoir, was forced through the porous samples. The resul...

The sequential fully implicit (SFI) scheme was introduced (Jenny et al. 2006) for solving coupled flow and transport problems. Each time step SFI consists of an outer loop, in which there are inner Newton loops to implicitly sequentially solve the pressure sub-problems. In standard SFI, sub-problems usually solved with tight tolerances at every iteration. This can result wasted computations tha...
