Abstract: Composition comprising a plurality of particulates wherein at least some particulates are at least partially covered with a coating that impedes the intrusion of water into the particulates; and, a silica scale control additive, wherein the silica scale control additive is capable of suppressing silica scale build-up proximate the plurality of particulates. Some compositions further include a treatment fluid wherein and the silica scale control additive are present in the treatment fluid.

Abstract: Treatments and compounds can be useful in subterranean formations where particulates and/or surfaces may be subject to silica scale build-up. Certain embodiments pertain to utilizing silica scale control additives with particulate packs. Of these, certain methods may treat particulate packs in a subterranean formation with silica scale control additives, certain methods may combine silica scale control additives with particulates prior to formation of a particulate pack, and certain compounds may provide the features of both silica scale control additives and particulates.

Abstract: A subterranean zone is treated by exothermically decomposing hydrogen peroxide in or near the subterranean zone. The decomposed hydrogen peroxide yields at least oxygen and heated water. The oxygen is combusted to further heat the heated water. The heated water is introduced into subterranean zone to treat the subterranean zone. In certain instances, the heated water is heated to produce 100% quality steam. Additional water may be supplied for treating the subterranean zone, for example, by supplying the hydrogen peroxide in solution with water.
