Black Rice Huskash is a Useful Template for Foam Stability to Enhance Oil Recovery (EOR)

摘要

In the present study, we have studied the advantages of using black rice husk ash nanoparticles as a foam stabilizer. It was shown that nanoparticles can potentially improve the foam stability; therefore, using nanoparticles allows one to reduce the surfactant or polymer concentration needed to control gas mobility in the reservoir. In the previously published studies, the authors reported the results of using nanoparticles for this particular application. The study aims to improve the foam-forming ability and foam stability when used in enhanced oil recovery technologies. Therefore, we have investigated the ability of the black rice husk ash to provide foam stability and foaming ability of additives. Black rice husk ash was used to produce stable foam in the process of injection of CO2 and N-2 gases. Various characterization techniques were used to investigate the properties of the black rice husk ash. Black rice husk ash at various concentrations (ppm) was mixed with high-performance anionic foaming surfactants. In this study we used sodium dodecyl benzene sulfonate (SDBS) anionic surfactant. The static foam tests were performed at ambient temperature by bubbling the CO2 and N-2 gases through the solution. The CO2 and N-2 gas-injection laboratory technical evaluations have been reported. The analysis results showed that the contents of silica nanoparticles of black rice husk ash can enhance the foaming ability and provide stability of the foam. Black rice husk ash has attracted increasing interest as a potential additive when used in enhanced oil recovery (EOR) technologies.
