- Demand for Surfactant Flooding
Solutions Remains Northbound
At the temperature of 45[degrees]C and the constant flow of 0.1 mL/min, the experiments of water flooding, surfactant flooding, polymer flooding, and SP flooding are conducted.
The results of polymer flooding, surfactant flooding, and SP flooding are shown in Table 4.
Their flooding experiments revealed that NPs could efficiently enhance surfactant flooding with greater additional oil recovery because of the inclusion of NPs into surfactant solutions.

Capillary number theory is regarded as the basic theory in polymer flooding, surfactant flooding, polymer-surfactant flooding (SP), and alkali-surfactant-polymer flooding (ASP), which are more appealing enhanced oil recovery (EOR) techniques in low oil price era.
The importance of frontal stability of surfactant flooding without mobility control at velocity less than critical one required for a gravity stable displacement was well studied [15,16].
This method includes surfactant flooding
(including foam) polymer displacement, alkaline displacement, acid displacement, chemical reagents displacement, and microbiological treatment.
Among specific topics are modeling plasma flow with particle classes for different charge carriers and neutral particles, particle interactions in oscillatory Stokes flow, global eigenmodes of free-interface vertical liquid sheet flows, horizontal air-water flow pattern recognition, and pore-scale observation of surfactant flooding
for weakly water-wet porous media.
According to the oil recovery improving mechanisms of low frequency vibration and surfactant, low frequency vibration assisting with surfactant flooding
will be talked about in this paper.
During surfactant flooding
lowering of the interfacial tensions helps recover additional oil by reducing the capillary force.
is one of the most promising techniques to enhance oil recovery from low pressure depleted reservoirs.
