| 研究開始時の研究の概要 |
One of the major challenges of crude oil production using carbon dioxide (CO2) injection is the deposition of heavy fractions. These fractions consisting of asphaltenes, wax and/or resins, precipitate when the oil is expelled from underground.This research aims at alleviating the precipitation in asphaltenes by treating the crude oil with modified poly-vinyl alcohol (mPVA) and stabilized nanofluids (NF). mPVA and NF are expected to scavenge asphaltenes, which are in suspension in the crude oil.
|
| 研究成果の概要 |
The research investigated the synergy between silica oxide nanoparticles and polyvinyl alcohol in mitigating the deposition of the deposition in asphaltenes, which is a major challenge in oil and gas industry.
|
| 研究成果の学術的意義や社会的意義 |
the present research proposed a hybrid production scheme in which the nanofluid should be injected ahead of the carbon dioxide. This approach promotes the adsorption the polar asphaltenes onto the surface of the nanoparticles allowing thereby oil dissolution by CO2.
