Abstract
The invention relates to providing controlled delivery of subterranean fluid additives to a well bore treatment fluid and/or a surrounding subterranean environment using intelligent materials that respond to a magnetic stimulus to release subterranean fluid additives downhole in a subterranean environment. Methods disclosed include a method of releasing a subterranean fluid additive in a subterranean formation comprising: providing a magnetically-sensitive component that comprises a subterranean fluid additive; providing a magnetic source; and releasing the subterranean fluid additive in the subterranean formation from the magnetically-sensitive component using a magnetic force generated from the magnetic source.
