Polymer Flood
• Polymer is chemical additive
that increases viscosity of
injected water
• Reduces residual oil saturation
• Improves sweep efficiency
• Works best with heavier crudes
in high permeability reservoirs
with low waterflood recovery
factors
• The first identified projects are
at Giltedge and Medicine Hat
Glauc C
• Typical expected recovery
improvement is ~8 - 15% (rule
of thumb is 30% of the projected
waterflood recoverable oil)
