| چکیده انگلیسی مقاله |
Sodium Dodecyl Sulphate (SDSodium Dodecyl Sulphate (SDS) mediated Kono-Bono (KB) clay nanoparticles (NPs) applied in Enhanced Oil Recovery (EOR) have been investigated for the first time. This was done using synthesized KB clay NPs as a control and SDS-treated KB clay NPs experiments in a micro model to determine the oil recovery rate. The samples were prepared by dissolving 15 g of KB clay in a mixture of 450 ml of de-ionized water and 150 ml of varying SDS concentrations, magnetically stirred, dried at 110 °C for 90 minutes, and further calcined at 900 °C in a muffle furnace for 120 minutes. The samples were characterized with Fourier Transform infrared (FT-IR) Spectroscopy, Scanning Electron Microscopy (SEM), X-ray fluorescence (XRF), and X-ray Diffraction (XRD), respectively. FT-IR analysis indicated characteristic bending vibrations of Al-OH bands at 698 cm-1 and stretching modes at 780, 1056, and 3655 cm-1 for (Si-O and Al-Mg-OH) bands, respectively. SEM micrographs showed surfaces with varying platy polycrystalline particle sizes, while XRF results identified the clay as kaolinite with silicate and alumina > 30 and 16%, respectively. The flooding experiment revealed that the SDS-mediated KB clay NPs (8.33 mM SDS) gave the highest total oil recovery of 66.25 % at 0.10 wt. %. Optimizing oil recovery at 8.33 mM by varying concentrations of KBC2 at 0.05, 0.10, 0.15, 0.20, and 0.25 wt. % gave a remarkable oil recovery rate of 85.27% at 0.15 wt.%. Thus, 0.15 wt. % KBC2 is recommended for application in oil recovery.S) mediated Kono-Bono (KB) clay nanoparticles (NPs) applied in Enhanced Oil Recovery (EOR) have been investigated for the first time.
