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.
Claims4
A method of inhibiting scale formation in a subterranean reservoir, comprising:
- depositing silica-based nanoparticles on a surface of the subterranean reservoir,
- transporting a scale inhibitor to the surface of the subterranean reservoir,
- adhering the scale inhibitor to the silica-based nanoparticles through a chemical interaction, and
- inhibiting scale formation in the subterranean reservoir,
- wherein the silica-based nanoparticles and the scale inhibitor are added to the subterranean reservoir separately, and
- wherein the method excludes a step of adding a clay mineral to the subterranean reservoir.
