This study uses a sand pack experimental approach to investigate the effect of black rice husk ash (BRHA) on foam stability. The high silica content of BRHA enhances foam stability. Sodium dodecyl benzene sulphonate (SDBS) was used as the anionic surfactant, and the best-performing anionic foaming surfactants were mixed with BRHA at varying concentrations (ppm). FTIR analysis of the black rice husk revealed a high silica content, which proved beneficial for foam stability and performance. For the experiment, a 30-centimeter sand pack was prepared. Liquid SDBS surfactant and Concluders were used in the experiment. Two core flood testing methods were employed: one without a sand pack and one with a sand pack. Both SDBS surfactant and black rice husk ash were used at a 0.5% concentration. To further investigate the effect of BRHA foam at the microscopic level and evaluate its stability and performance at the core level, a microscopic foam visualization experiment was conducted. The results demonstrate that BRHA improves foam stability, likely due to its high silica content, which aids in foam stabilization under sand pack conditions in Enhanced Oil Recovery (EOR).
