... of similar structures are lumped into single bead. Beads don't have fixed properties being composed of different elements. Bead properties need to be determined either using molecular simulation or by experimental values. In this work bead-bead repulsion parameters were calculated using molecular simulations...

... uncertainty after five years of waterflooding, we select three groups of 10 cases out of 100 with similar water breakthrough dates at the four production wells. We then simulate five years of polymer injection. We allow that the polymer process might fail in situ and viscosity could be half that intended. We...

We performed systematic simulations and studied the impact of adsorption (retention), shear thickening, deep bed filtration, and external cake formation to explain the well injectivity behavior of polymer. The simulation results indicate that the gradual increase in bottomhole...

For sintered glass bead packs and sandstone rock we were able to typically match the porosity within 10 % and the permeability within 15 %. Based on the data acquired in the first step digital models are built to explore...
