Summary: The use of green, eco-friendly, efficient, and sustainable surfactants for enhanced oil recovery (EOR) is crucial. A novel natural surfactant extracted from oat was found to be highly efficient and stable for EOR applications. Different salts were tested, and Na2CO3 showed the best compatibility and achieved the most significant reduction in interfacial tension (IFT). Core flooding tests demonstrated that using the natural surfactant with Na2CO3 as a tertiary recovery agent increased the oil recovery factor by 28.89%.

Summary: Nanomaterials, specifically silica-graphene quantum dots (Si-GQDs), have been synthesized and dispersed in water to form nanofluids. These nanofluids exhibit significant reduction in interfacial tension and wettability alteration, leading to enhanced oil recovery from carbonate reservoirs. The experimental results show that the nanofluids formulated with 1000 ppm Si-GQDs in distilled water enable an additional 14.4% oil recovery due to the reduction in interfacial tension and contact angle.

Summary: This research focuses on utilizing graphene oxide, a D118 SuperPusher compound, and a natural surfactant to enhance oil recovery. The study optimized the efficiency of the enhanced oil recovery process through a multi-component approach. The application of the natural surfactant led to a decrease in interfacial tension, particularly in carbonate rock formations. Furthermore, graphene oxide nanoparticles were synthesized and incorporated into the surfactant-polymer system to create a surfactant-polymer-nanoparticle fluid. Core flooding investigations validated the effectiveness of the suggested fluid formulation for enhancing oil recovery in both sandstone and carbonate reservoirs.

Summary: In this study, the laponite particles were modified using the interfacial reaction method with 3-glycidoxypropyltrimethoxysilane and octadecylamine, and their structure, morphology, and displacement performance were tested. The modified particles were characterized using elemental analysis, Fourier-transform infrared spectrometer, thermogravimetric analysis, and transmission electron microscopy, showing successful modification of the laponite particles. The study found that the modified particles, called LAS, could accumulate at the interface, reduce interfacial tension, and have a good emulsification effect. LAS could also change the wettability of rocks and extract oil at low concentration.

Summary: Green enhanced oil recovery (GEOR) is an environmentally friendly technique that improves oil recovery efficiency by injecting specific green fluids to increase residual oil production. Studies have shown that certain green SP formulations can significantly enhance residual oil production in carbonate cores, such as a mixture of APG, XG, and butanone.
