Nanofluid Structural Forces Alter Solid Wetting, Enhancing Oil Recovery

Nanofluids have attracted significant research interest for their promising application in enhanced oil recovery. One striking feature leading to the outstanding efficiency of nanofluids recovery is structure nanoparticles, which induces oscillatory structural forces confined space between fluid–fluid interfaces or air–liquid and liquid–solid interfaces. To promote understanding recovery, we reviewed origin theory forces, factors affecting magnitude, experimental techniques demonstrating impacts on We also methods, where benefits provided by are directly manifested. The wetting spreading solid surfaces, ultimately enhances separation from reservoir. Some imbibition tests demonstrated as much 50% increased compared cases were absent.
