Photon–phonon interaction of surface ionic adsorption within electric double layer in reservoir sandstone

Abstract

In solid materials, the interaction of photon comprises ionic and electronic oscillating charges, while phonons are the collection of excitations in arrangement of atoms and molecules in both solid and liquids materials at certain frequencies. The distribution of ions and charges under electric double layer in reservoir sandstone and the kind of electrostatic environments they create are major challenges to the recovery of residual hydrocarbons in depleted and marginal fields. Saturated Berea sandstone was used to investigate interaction of ions on sandstone and crude oil with the aid of Scanning electron microscopy; Energy Dispersive X-Ray mapping (EDX), Fourier Transform Infrared Spectroscopy (FTIR), X-ray fluorescence (XRF), Raman spectral analysis and Core flooding experiment were used to determine the absorption of ions with and without electromagnetic wave intensity. This paper provides insight on surface adsorption of ion within electric double layer and the effect of photon–phonon interaction with reservoir sandstone under EDL mechanisms. Result reveal that the absorption is located between 1–50 μm ranges this is referred to infrared absorption bands, the influx of electrolyte contributes to well dispersion and interaction of both positive and negative ions on the sandstone. It shows that the domination of the repulsive double layer is due to high proportion of NaCl electrolyte which has highest negative zeta potential for the fluid stability. Comparison of the major ions and composition of the ions on the sandstone reacted; indicate fluid mobility due to water-rock interaction.
