Beadpack experiments and numerical simulations have been carried out t
o study flow displacements, effluent profiles and streamline patterns
for layered systems with flow not parallel to the layers. The effects
of layer thickness, permeability contrast, angle of layer to flow dire
ction, mobility ratio and flood rate have been examined. Each of these
parameters influence the displacement profiles, and disperse the floo
d front. Such real effects must be considered when subsuming reservoir
heterogeneities in average reservoir parameters in simulation studies
, or interpreting core tests.
