Abstract

Scientist have been using chemical treatment to alter the wettability of near wellbore region for condensate banking removal. However, this technique performed unsatisfactorily as the chemical treatment only reduce the surface free energy without modifying the surface roughness and affects the gas relative permeability negatively. Hence, in the present study, an alternative surface-modified nanoparticle using fluorine-based chemicals was developed as a new wettability alteration agent since fluorine exhibits high degree of water and oil repellency. The new wettability alteration agent was evaluated based on FTIR, DLS and TGA characterization. The results show that the surface of nanoparticles has been modified with fluorine-based chemicals coating and this is proven from: FTIR spectra with new peaks observed; DLS characterization with incremental size of surface-modified nanoparticles; and TGA with decomposition rate of coating agents. Implications of the results will path the way for future research direction in using fluorine-surface-modified-nanoparticles as a wettability alteration agent.

Highlights

FTIR, DLS and TGA characterization confirmed the success of fluorine-surfacemodified nanoparticles development
The synthesis of fluorinated-silica-nanoparticles using perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) as a wettabilty alteration agent were reported for the first time in this paper
The solution was sonicated for 30 minutes with temperature at 70 °C, above the melting point of PFOA and PFNA

Summary

Introduction

1. Nanosilica surface is successfully functionalized with fluoroalkanoic acid. 2. FTIR, DLS and TGA characterization confirmed the success of fluorine-surfacemodified nanoparticles development. The synthesis of fluorinated-silica-nanoparticles using perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) as a wettabilty alteration agent were reported for the first time in this paper. The method for synthesizing and characterizing is described in detail.
