| Abstract: |
| The unique characteristics of materials at the nanoscale make them a good candidate to use in the enhanced oil recovery (EOR) processes. Therefore, in this study, the effect of functionalized multi-walled carbon nanotube/silica nanohybrids on the oil recovery factor is investigated experimentally and nanofluids were injected into a glass micromodel for the first time. The nanohybrids synthesized by using sol-gel method. Micromodels as microscale apparatuses considered as 2D porous medium. Because they enable visual observation of phase displacement behavior at the pore scale. Distillated water used as the dispersion medium of nanoparticles for nanofluids preparation. A series of runs designed for flooding operations included water injection, carbon nanotube/water injection and two nanohybrids with different weight of MWCNT to the overall weight of the nanohybrid structure (10% and 70%) into the distilled water. Also, the oil recovery factor was considered as the goal parameter to compare the results. It has been found that functionalized multi-walled carbon nanotube/silica nanohybrids have a great potential in enhanced oil recovery processes. Results showed that addition of nanohybrids into distillate water causes enhancement of sweep efficiency. In other words, the fingering effect decreases and higher surface of porous medium is in contact with the injected fluid. So the higher amount of oil can produce from the porous medium consequently. By injecting nanofluid with 0.1 wt. % of carbon nanotube, the oil recovery factor increases about 11 % in comparison with water injection alone. Also by increasing the weight of MWCNT to the overall weight of the nanohybrid structure from 10% to 70%, the oil recovery factor increases from 35% to 39%. |
