Paper Number: SPE-181149-MS
... society of petroleum engineers concentration viscosity surfactant injection A sample of viscous mineral oil (1015 mPa.s at 23°C) is displaced by water, surfactant, polymer and SP systems under various flow rates. The SurFlood HORA-W805 surfactant is used, which is a commercial surfactant supplied...

... the impact of nitrogen concentration in steam with 14 surfactants and found that resistance factor is higher with 50 mol % of N 2 in steam than with 5 mol % of N 2 in steam. The resistance factor is defined as the ratio of pressure drop due to foam flow with the pressure drop with gas and brine...

Simulation results showed that the main acting parameters for the method of recovery are the oil viscosity and the concentration of surfactant for foam generation. The initial increases in surfactant concentration were that promoted a greater increase in oil...
