Combination of nano-bentonite stabilized foam and ultra-low IFT surfactant additives assisted steam injection to enhanced heavy oil recovery

Performance Evaluation of the Green Surfactant-Treated Nanofluid in Enhanced Oil Recovery: Dill-Hop Extracts and SiO2/Bentonite Nanocomposites

“…16 On the other hand, the hydrophobic nature of the nanocomposites can alter the wettability of the rock surface toward the water-wet and reduce the capillary forces. 17 Recently, several nanocomposites were evaluated for their potential role in enhancing oil recovery applications, such as Fe 3 O 4 /mineral−soil NCs, 13 polymer nanofibers, 18 polyacrylamide-grafted silica NCs, 19 Fe 3 O 4 @ Chitosan NCs, 20 GO/Pd NCs, 21 TiO 2 /xanthan gum NCs, 23 and nanobentonite. 23 The mentioned studies stated the significant role of the nanomaterials in the interfacial tension (IFT) reduction, wettability alteration, foam stability, and improvement of the oil recovery.…”

Meanwhile, surfactants are chemical compounds that reduce the IFT between oil and water, facilitating the movement of oil toward production wells.…”
