Abstract
The present invention includes compositions and methods of supplying a corrosion inhibitor including placing a corrosion inhibitor attached to a nanostructure carrier, placing the nanostructure carrier containing the corrosion inhibitor at a location and the nanostructure carrier is capable of releasing the corrosion inhibitor.
Claims13
A method of supplying a corrosion inhibitor to a downhole metal component, comprising:
- forming a nanostructure carrier configured as an insert on a downhole tool;
- impregnating the nanostructure carrier with a corrosion inhibitor;
- positioning the nanostructure carrier in an environment adjacent a downhole component;
- and
- releasing the corrosion inhibitor from the nanostructure carrier into the environment adjacent the downhole metal component.

A method of supplying the corrosion inhibitor to a downhole metal component, comprising:
- forming a nanostructure elastomer, configured for placement within a downhole tool;
- impregnating the nanostructure elastomer with a corrosion inhibitor;
- positioning the nanostructure elastomer in an environment adjacent a downhole component;
- and
- releasing the corrosion inhibitor from the nanostructure elastomer into the environment adjacent the downhole metal component.
