AbstractThe paper discussed the development of an Ultra-Low Interfacial Tension (IFT) foaming surfactant based on a combination of improved as-synthesized surfactant (CBH) consist of as-synthesized oleic amido propyl betaine with mixtures of co-solvents and PETRONAS’ in-house patented foaming-based surfactant (IVF) which consist of amphoteric and anionic surfactant; as well as the performance evaluation of the surfactant in Enhanced Oil Revery (EOR) application. CBH and PETRONAS (IVF) foam-based surfactants were used in the formulation as ultra-low IFT and foaming components, respectively. The surfactant's development has been highlighted, and the findings have been discussed in detail. Due to the good foaming and IFT output at ultra-low levels, the combination of 0.3wt.% IVF and CBH at a ratio of 2: 8 was suggested. The addition of a non-ionic scleroglucan polymer from the polysaccharide group was chosen to study the stabilizing effect to the foam and the ultra-low IFT value of the formulation. Based on the findings, the presence of scleroglucan in the formulation has a significant effect on the performance of IFT and foam of the formulation when compared to the original formulation.
