Abstract

The aim of enhanced oil recovery (EOR) is to influence the fluid-fluid properties and fluid-rock properties between the injected fluid and the residual oil phase to improve recovery efficiency. New methods of improving recoveries have been investigated since they provide lower risks, costs and uncertainty as compared to exploring for new reserves. Water enhanced with nanoparticles (nano-fluid) has recently gained research interest for enhanced oil recovery because of the possible physical and chemical properties imparted by the nanoparticles. The purpose of this research was to investigate and improve oil recovery after water flooding by nanofluid flooding. Nanoparticle used was silica nanoparticles (SiO2) suspended in deionized water at 0.05wt% concentrations. The results from the core samples show an additional oil recovery of 4.29%, 2.022% and 1.86% respectively from three (3) cores (core 2, core 5 and core 6) at nano flooding rate of 0.5cc/min. Core 7 gave a recovery of 33% during water flooding and 38.2% during nano-fluid flooding thus giving an incremental recovery of 5.2%. These results have validated the effectiveness of chemical flooding especially nanoparticles to successfully recover crude oil from reservoirs after water flooding usefulness has declined.
