Abstract

Viscosity is crucial to improve the efficiency of injected fluids for oil displacement in reservoirs. Traditionally, research has focused on polymers that help reduce the mobility of injected fluids, while surfactant viscosity has received less consideration. This research investigated the viscosity behavior of methyl ester sulfonate (MES) and sodium lauryl sulfate (SLS) surfactant solutions using a machine learning method—adaptive neurofuzzy inference system (ANFIS). This study aimed to predict the viscosity of surfactant solutions. Experimental data included viscosity measurements of 36 MES and SLS samples at various concentrations and temperatures, obtained by digitizing viscosity curves. These data served as input and validation for the ANN and ANFIS models. The results showed that ANFIS predicted viscosity values ​​reliably, yielding only 1.33% and 0.43% differences for MES and SLS, respectively. Comparison of viscosity prediction with Artificial Neural Network (ANN) showed that ANFIS prediction was better, because ANN yielded two deviating predictions.

Abstract

The increasing decline in oil production from mature reservoirs has encouraged the development of more effective and environmentally friendly Enhanced Oil Recovery (EOR) technologies. Surfactant flooding is a promising chemical EOR method because it can reduce interfacial tension, modify rock wettability, and mobilize trapped residual oil. This study aimed to evaluate the effectiveness of palm oil-based Methyl Ester Sulfonate (MES) surfactant in improving oil recovery through core flooding and spontaneous imbibition techniques. The experiment used Berea sandstone cores with approximately 21% porosity and 100 mD permeability, light crude oil with a gravity of 39°API, and two surfactant solution conditions: 5,000 ppm salinity with 0.5% MES concentration and 10,000 ppm salinity with 2% MES concentration. The results showed that the low-salinity MES solution provided better performance than the high-salinity condition. In the core flooding test, the 5,000 ppm salinity and 0.5% MES solution achieved the highest recovery factor of 84.74%, whereas the 10,000 ppm salinity and 2% MES solution achieved 62.63%. In the spontaneous imbibition test, the low-salinity condition resulted in 51.94% oil recovery, compared with 45.24% under high-salinity conditions. These findings indicate that lower salinity enhances surfactant stability, improves interfacial tension reduction, and promotes oil mobilization. Therefore, palm oil-based MES surfactant demonstrates strong potential as a sustainable chemical EOR agent for sandstone reservoirs.
