Cutting Costs Through Chemical Flooding New developments of chemical EOR Enhanced secondary recovery Low Concentration SP “Cold” Heavy oil recovery Oil Sand Shale – oil/gas recovery Economics and success of chemical flooding
30 minutes at ambient temperature Oil Sand Separation Add the oil sand to 0.1% Surfactant solution Shake the flask 30 minutes at ambient temperature
Oil Sand Separation Low concentration surfactant required Can be used at ambient or higher temperature No steam is needed No solvent is needed Can be used as cold reservoir in-situ oil / sand separation or surface oil / sand separation

Wettability Alteration IFT > 1 mN/m 0.1% SS-870 IFT = 10-3 mN/m IFT = 10-1 mN/m
Micro-Fractures Generation Different fracturing techniques can be used to encourage the surfactant solution leak off, increase the capillary force, reduce the IFT and alter the wettability
