Abstract

The use of surfactants in Chemical Enhanced Oil Recovery (CEOR) plays a crucial role in maximizing residual oil recovery in reservoirs. However, conventional synthetic surfactants often raise environmental concerns and contribute to high production costs. Therefore, this study aims to analyze the potential of biosurfactants synthesized from Palm Kernel Oil (PKO) as an environmentally friendly alternative for CEOR applications, particularly under low salinity conditions and elevated temperatures (50°C and 60°C). The biosurfactant synthesis involved sulfonation, purification, and neutralization processes. Characterization of the synthesized biosurfactant was carried out using Fourier Transform Infrared (FTIR) spectroscopy to identify functional groups, a Foaming Test to evaluate foamability and foam stability, a Compatibility Test to assess the stability of the solution in 10,000 ppm brine, and a Filtration Test to evaluate the risk of pore blockage. The results showed successful biosurfactant synthesis with the presence of sulfonate functional groups confirmed by FTIR spectra. The Foaming Test demonstrated good foam-forming capability and stability. The Compatibility Test showed homogeneous solutions with no precipitate formation at both 50°C and 60°C after 72 hours. Additionally, the Filtration Test yielded a linear volume-time graph, indicating no clogging tendency. Overall, biosurfactants derived from PKO exhibit promising characteristics as a potential alternative surfactant in CEOR applications, particularly under low salinity and hightemperature conditions.
