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.

Claims (10)

1 . 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.

2 . The method of claim 1 , wherein the chemical interaction comprises forming a bond between the scale inhibitor and the silica-based nanoparticles.

3 . The method of claim 1 , further comprising adhering the silica-based nanoparticles to the surface of the subterranean reservoir through a second chemical interaction.

4 . The method of claim 1 , wherein the scale inhibitor comprises a member selected from the group consisting of a phosphonate, a sulfonate, a phosphate ester, a polymeric scale inhibitor, and any combination thereof.
