Adsorption of surfactant onto rock surfaces is dependent upon a number of factors, including
characteristics of both the adsorbent and surfactant molecules. Considering that surfactant …

The adsorption of surfactants from aqueous solutions in porous media is essential in
enhanced oil recovery (EOR) from oil reservoirs. Surfactant loss that is due to adsorption by …

Emphasizing upon the effect of rock mineralogy, aqueous media salinity and temperature,
this work addresses the adsorption characteristics of surfactant on real reservoir rocks. The …

Surfactant EOR received attraction due to its extreme capability to increase displacement
efficiency by altering the wettability, lowering the oil/water interfacial tension and ultimately …

Enhanced oil recovery (EOR) processes have a great potential to maximize oil recovery
factor of the existing reservoirs, where a significant volume of the unrecovered oil after …

Surfactant imbibition is a new method to improve the oil recovery from tight rocks. The idea
of this method is to introduce diluted surfactant solution (0.1-0.25% in active concentration) …

Injection of surfactants solutions is the most promise in chemical oil recovery method for the
reduction of the remaining oil in a reservoir at the end of its exploitation. Surfactant …

The application of surfactants in enhanced oil recovery (EOR) has revealed over the years
various challenges that impose limitations on the successful implementation of surfactant …

One of the main factors in chemical-based enhanced oil recovery, especially surfactant
flooding, is a surfactant adsorption loss onto the reservoir rock. The main aim of this article is …

Adsorptions of nonionic and anionic surfactants onto sandstone and carbonate surfaces
were measured. Nonionic surfactants studied were polyethoxylated octyl phenols and …
