Abstract
The present disclosure provides methods for inhibiting scale formation in subterranean reservoirs. The methods may include depositing silica-based nanoparticles on a surface of the subterranean reservoir and transporting a scale inhibitor to the surface of the subterranean reservoir. The scale inhibitor may adhere to the silica-based nanoparticles through a chemical interaction. The silica-based nanoparticles may adhere to one or more surfaces within the subterranean reservoir.

A method of inhibiting scale formation in a subterranean reservoir, comprising:
- adding functionalized silica-based nanoparticles together with a scale inhibitor to a subterranean reservoir, wherein the functionalized silica-based nanoparticles comprise silicon dioxide and a member selected from the group consisting of an amine, a thiol, a halide, a carboxylic acid, and any combination thereof,
- adhering the scale inhibitor to the functionalized silica-based nanoparticles through a chemical interaction, and
- inhibiting scale formation in the subterranean reservoir.
A method of inhibiting scale formation in a subterranean reservoir, comprising:
- preflushing the subterranean reservoir with an aqueous solution,
- delivering a scale inhibitor and silica-based nanoparticles to a wellbore of the subterranean reservoir, wherein the silica-based nanoparticles comprise silicon dioxide and a member selected from the group consisting of an amine, a thiol, a halide, a carboxylic acid, and any combination thereof,
- transporting the scale inhibitor and silica-based nanoparticles to a surface within the subterranean reservoir,
- adhering the scale inhibitor to the silica-based nanoparticles through a chemical interaction, and
- inhibiting scale formation in the subterranean reservoir.
