Description
Shoufei Lu and three co-authors made smart nanosheets to squeeze more oil from tight rock in a 2025 study. In low-permeability fields, much oil stays trapped because water cannot push it out. Their sheets are flat flakes with two faces: one that loves water and one that shuns it.
Flakes beat round particles here because their flat shape gives more surface and a stronger grip at the oil-water boundary. A fluid of the flakes stayed stable in very salty water at high heat. It mixed oil into droplets well and cut the tension at the boundary to a very low value. It also flipped rock surfaces from oil-loving to water-loving, freeing trapped oil. In lab cores, the best case recovered about seventy-one percent of the oil. The authors present the sheets as a candidate for fields where normal flooding fails.
