Abstract
Treatments and compounds useful in subterranean formations are discussed, with particular attention to those formations where surfaces may be subject to silica scale build-up. Certain embodiments pertain to utilizing silica scale control additives with remediation and stimulation treatments. One example of a suitable method includes providing an acidic treatment fluid comprising: a base fluid, an acid, and a silica scale control additive; contacting at least a portion of a subterranean formation with the acidic treatment fluid; and allowing the acidic treatment fluid to interact with silica scale buildup in the subterranean formation so that at least a portion of the silica scale buildup is removed.

A method comprising:
- providing an acidic treatment fluid comprising:
- a base fluid,
- an acid, and
- a silica scale control additive;
- contacting at least a portion of a subterranean formation with the acidic treatment fluid;
- and
- allowing the acidic treatment fluid to interact with silica scale buildup in the subterranean formation so that at least a portion of the silica scale buildup is removed.
A method comprising:
