Surfactant flooding<\/em> is one of the Chemical Enhanced Oil Recovery<\/em> (EOR) methods that plays an important role in increasing oil recovery by reducing interfacial tension<\/em> (IFT) and mobilizing oil trapped within the pores of reservoir rock. This study evaluates the performance of two commercial surfactants through the analysis of the relationship between capillary number<\/em> and residual oil saturation<\/em> using a modified transparent micromodel<\/em> approach combined withigital image analysis<\/em>. This approach provides a deeper understanding of fluid displacement dynamics in porous media during the surfactant flooding<\/em>.<\/p>\n\n\n

Research Background and Objectives<\/strong><\/p>\n\n\n\n

Surfactant flooding<\/em> has long been developed as one of the Chemical EOR methods that is effective in improving oil mobility within the reservoir. By reducing the interfacial tension<\/em> between oil and water, surfactants allow oil that was previously trapped within rock pores to be more easily mobilized and produced.<\/p>\n\n\n\n

In laboratory studies, surfactant flooding<\/em> performance is often analyzed using the Capillary Desaturation Curve<\/em> (CDC), which describes the relationship between changes in residual oil saturation<\/em> and capillary number<\/em>. Capillary number<\/em> itself is the ratio between viscous forces\u2014which are influenced by fluid viscosity and injection rate\u2014and capillary forces, which are influenced by the interfacial tension<\/em> between two immiscible fluids.<\/p>\n\n\n\n

This study aims to evaluate the performance of two commercial surfactants by analyzing how changes in the capillary number <\/em>can affect the reduction of residual oil saturation<\/em>. To increase the capillary number<\/em>, the value of interfacial tension<\/em> between surfactants and crude oil<\/em> was modified until reaching the ultra-low <\/em>IFT condition, allowing the capillary number<\/em> to increase by three to five orders of magnitude.<\/p>\n\n\n\n

Experimental Approach Using a Modified Micromodel<\/strong><\/p>\n\n\n\n

This study uses a transparent modified micromodel<\/em> that enables direct visualization of fluid movement in porous media. This approach provides a clearer picture of the oil displacement process during surfactant injection.<\/p>\n\n\n\n

To represent reservoir conditions more realistically, the micromodel was modified by adding quartz<\/em> and cement<\/em>, allowing fluid\u2013rock interactions to be observed more representatively. The experimental process was then analyzed using Digital Image Analysis<\/em> (DIA) to calculate important parameters such as initial oil saturation<\/em>, residual oil saturation<\/em>, water saturation<\/em>, and surfactant saturation<\/em> quantitatively.<\/p>\n\n\n\n

This study consists of two main testing stages: a static test<\/em> to evaluate fluid compatibility through CMC\u2013IFT testing, and a dynamic test<\/em> using the micromodel to directly observe the surfactant flooding<\/em> process within porous media.<\/p>\n\n\n

Research Results and Insights<\/strong><\/p>\n\n\n\n

The results of the study show that the reduction of interfacial tension<\/em> between the surfactant solution and crude oil <\/em>directly influences the reduction of residual oil saturation<\/em>, which ultimately increases oil recovery.<\/p>\n\n\n\n

However, the study also shows that the lowest interfacial tension<\/em> does not always result in the highest oil recovery<\/em> . This finding provides an important perspective that an increase in capillary number<\/em> at a certain level is sufficient to improve oil mobilization, without always having to reach the condition of ultra-low<\/em> IFT.<\/p>\n\n\n\n

The approach using a modified micromodel<\/em> also demonstrates significant potential as an experimental method that is simpler, faster, and more cost-efficient compared to conventional methods such as coreflood test<\/em>, while still being able to provide detailed insights into fluid\u2013rock interactions at the pore scale.<\/p>\n\n\n
