Abstract

In oil extraction, surfactant injection is enhanced oil recovery chemical technique used in unconventional reservoirs. Extreme reservoir conditions, such as high temperatures and pressures, promote the degradation and loss of effectiveness of conventional surfactants. Therefore, it is necessary to synthesize surfactants that can be used under adverse conditions. Gemini surfactants have a low critical micellar concentration, form micelles more easily, and decrease the oil-water interfacial tension 10 to 100 times more than conventional surfactants. On the other hand, polydimethylsiloxane-based surfactants maintain their surface properties even at high temperatures and can mitigate foam formation, making them excellent candidates for use in oil recovery. In this work, a Gemini surfactant was synthesized from polydimethylsiloxane with diglycyl ether end groups modified with 1-octanol. Subsequently, its structural properties were analyzed by nuclear magnetic resonance, infrared spectroscopy, and its surface properties were determined by the sessile contact angle method.
