Abstract

M Metode enhanced oil recovery (eor) menggunakan injeksi surfaktan bertujuan meningkatkan perolehan minyak, namun efektivitasnya dipengaruhi oleh adsorpsi surfaktan pada permukaan batuan. penelitian ini bertujuan menganalisis pengaruh adsorpsi surfaktan methyl ester sulfonate (mes) berbasis kelapa sawit terhadap recovery factor pada minyak 35Â°api dan 48Â°api menggunakan metode core flooding. penelitian dilakukan secara eksperimental melalui pengujian densitas, aqueous stability, phase behavior, interfacial tension (ift), wettabilitas, adsorpsi statis dan dinamis, serta core flooding dengan variasi salinitas brine 5.000â€“10.000 ppm dan konsentrasi surfaktan 0,2â€“2%. hasil penelitian menunjukkan bahwa seluruh formulasi surfaktan stabil pada seluruh variasi salinitas. nilai adsorpsi meningkat seiring bertambahnya konsentrasi surfaktan, dengan adsorpsi statis lebih tinggi dibandingkan adsorpsi dinamis. pengujian wettabilitas menunjukkan perubahan batuan menjadi water-wet, sedangkan core flooding menghasilkan total recovery factor sebesar 84% pada minyak 35Â°api dan 86% pada minyak 48Â°api. hasil penelitian menunjukkan bahwa adsorpsi memengaruhi efektivitas injeksi surfaktan karena mengurangi jumlah surfaktan aktif yang berperan dalam mobilisasi minyak, sehingga berpengaruh terhadap peningkatan recovery factor.

E Enhanced oil recovery (eor) using surfactant injection is one of the methods employed to improve oil recovery. however, its effectiveness is influenced by surfactant adsorption on the reservoir rock surface. this study aimed to analyze the effect of palm oil-based methyl ester sulfonate (mes) surfactant adsorption on the recovery factor of 35Â°api and 48Â°api crude oils using the core flooding method. the study was conducted experimentally through density, aqueous stability, phase behavior, interfacial tension (ift), wettability, static and dynamic adsorption, and core flooding tests using brine salinity variations of 5,000â€“10,000 ppm and surfactant concentrations ranging from 0.2% to 2%. the results showed that all surfactant formulations remained stable under all salinity conditions. adsorption increased with increasing surfactant concentration, while static adsorption values were consistently higher than dynamic adsorption values. wettability tests indicated a shift in rock wettability toward water-wet conditions, whereas the core flooding test produced total recovery factors of 84% for 35Â°api crude oil and 86% for 48Â°api crude oil. the findings indicate that surfactant adsorption affects the effectiveness of surfactant injection by reducing the amount of active surfactant available for oil mobilization, thereby influencing the recovery factor.
