Abstract

Sodium Dodecyl Sulphate (SDS) mediated Kono-Bono (KB) clay nanoparticles (NPs) applied in Enhanced Oil Recovery (EOR) has been investigated for the first time. This was done using synthesized KB clay NPs as control and SDS treated KB clay NPs experiments in a micro model to determine the rate of oil recovery. 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 Infra-red (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. Flooding experiment conducted revealed that the SDS mediated KB clay NPs (with 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.
