Abstract: Abstract A streamline type mathematical model has been developed which may be used to study oil recovery by viscous waterfloods for any desired well spacing. The model was used to study the combined effects of permeability stratification, polymer concentration and viscous water slug size for a five spot injection pattern. Five different permeability profiles ranging from a homogeneous to a highly stratified reservoir were studied. It was found that viscous…
