The composition for enhanced oil recovery includes metal oxide or carbonate nanoparticles capped or encapsulated by a water soluble poly(ionic liquid) (PIL). The nanoparticles may be, e.g., CaCO, TiO, CuO.FeO, or ZrO. The poly(ionic liquid) may be a copolymer of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) with N-isopropyl acrylamide, N-vinyl pyrrolidone, methacrylic acid, or acrylamide. The composition is made by synthesizing the metal oxide or carbonate nanoparticles in the presence of the PIL. The resulting nanocomposite or nanomaterial alters the wettability of carbonate rock in a carbonate reservoir, releasing asphaltenic crude oil from the surface of the carbonate rock and replacing oil in the pores of the rock, thereby enhancing secondary and tertiary oil recovery.

A method of synthesizing silver nanoparticles from waste film includes providing waste film including a silver halide salt and gelatin, mixing the waste film with an alkaline solution to form a mixture, heating the mixture, and subjecting the mixture to ultracentrifugation to isolate silver nanoparticles in the mixture. The film can include waste radiographic or photographic film pieces. Glucose and/or polyvinylpyrrolidone (PVP) may be added to the mixture. The nanoparticles can have an average particle size of about 2 nm to about 10 nm. The silver nanoparticles can be resistant to synthetic stomach fluid and showed high antimicrobial activity.
