Adsorption of surfactant on Berea sandstone noticeably reduced after engaging this blend. The performance was studied by Core flooding, and Rheological studies...

... Abstract Surfactants are known for their unique property in lowering the interfacial tension (IFT) amid fluids injected and heavy crude oil of 22.3°API. In this present work, an original surfactant was formulated from natural oil (Castor oil) to see its use in enhanced oil recovery. The results...

...Interfacial Tension Reduction Interfacial tension is a measure of the cohesive energy present at the interface. It is measured in mN/m units ( Sari et al., 2019 ). Interfacial tension reduction is the key factor in enhanced oil recovery ( Sari et al., 2019 ). Interfacial tension (IFT...

... increase, reduction in interfacial tension (IFT), decrease in viscosity ratio, multi-component ionic exchange and wettability alteration are the best known. Adib (1990) concluded that oil recovery increased as the injected brine salinity increased up to 100,000mg/L of Nacl. However, increasing the brine...

... by the natural surfactants/emulsifiers in the crude oil. Emulsion droplets undergo spherical to ellipsoidal shape deformation and subsequent break up to smaller drops during flow. Droplet deformation is often resisted by the interfacial tension as determined by the Laplace pressure. The droplets will coalesce...

... major oil fields. However, substantial amount of oil is trapped inside the reservoir. This oil is being held by capillary force which depends on interfacial tension (IFT) between oil and water. Therefore, reducing the IFT releases the oil and enables greater recovery. Surfactant (surface acting agent...

... be attributed to reduction of interfacial tension between oil and water. For alcohol and starch, the ideal ratio of 1:1 gave the highest recovery. Beyond this ratio, oil recovery was observed to be reduced. The good result may have resulted partly from reduction of interfacial tension and partly as a result...

The appreciable oil recovery from the experiment buttresses the essence of lowering interfacial tension by the alkali through in-situ saponification to recover 25% oil in place (OIP). The surfactant in this experiment lowered interfacial tension to release more oil out from the sand pores...
