Preparation and Optimalization Nano Silica Base Nanofluid Effect in Wettability For Enhanced Oil Recovery

Abstract

This study focused on observing the effect of nano silica base nanofluid to change contact angle value on preparation to use for enhanced oil recovery (EOR). Nano Silica is known for its effectiveness on surfactant and easily synthesized and have lower cost production. The biggest problem in using nano silica for application on EOR process is figuring out how much is the proper amount that can be applied to give the best result. In this study, we use three concentration variation of nano silica base nano fluid and then compare them with salt water as base fluid to observe the impact reaction to EOR effectiveness by first testing its wettability measurement. For size measurement using PSA, the result shown for 0.01; 0.05; and 0.1 % variation in sequence is giving 330.8 nm, 326.1 nm and 341.4 nm respectively. For the wettability test, measurements that were completed within three days was giving contact angles of 56.31 ̊; 60.49 ̊; 62.01 ̊ sequence for base fluid, 20.39 ̊; 24.67 ̊; 27.21 ̊ sequence for concentration 0,1% nano fluid, 22.47 ̊; 28.35 ̊; 28.88 ̊ sequence for concentration 0.05% nano fluid, and 50.67 ̊; 54.66 ̊; 56.31 ̊ sequence for concentration 0.01% nano fluid. The result is shown, when higher concentration of nano fluid applied, it produces lower wettability and giving good potential to use for EOR.
