    摘要： The present invention relates to treatment fluids and compounds useful in subterranean formations, particularly those that retard deposition of silica scale in subterranean formations. Methods of the present invention comprise providing a treatment fluid having a pH of 6 or less that comprises an acidic base fluid and a non-polymeric silica scale control additive and introducing the treatment fluid into at least a portion of a subterranean formation. The non- polymeric silica scale control additive retards deposition of silica scale in the subterranean formation.

    摘要： The present invention relates to a process for treating natural fractures or fractures created in previous treatments that have closed at least partly in a subterranean formation comprising a step of introducing into the formation a treatment composition containing an iminodiacetic acid compound of the formula R-N-(CH 2 -COOH) 2 , or a salt thereof, wherein the R-N moiety can be derived from a natural amino acid COOH-CHR'-NH 2 that has been carboxymethylated at the nitrogen atom, or wherein the R-N moiety can be derived from an ethylenediamine NH 2 -(CH 2 -CH 2 -NH) n -H that has been at least partly carboxymethylated at the nitrogen atoms.

    摘要： 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.

    摘要： Treatment fluids containing biodegradable chelating agents can be used in various treatment methods. The methods can comprise providing a treatment fluid that comprises an aqueous base fluid and a chelating agent composition, and introducing the treatment fluid into at least a portion of a subterranean formation. The treatment fluids can also be used for treatment of pipes or tubing such as, for example, well bore pipes or tubing penetrating a subterranean formation and above-ground pipelines. Illustrative biodegradable chelating agents include, but are not limited to, glutamic acid diacetic acid, methylglycine diacetic acid, &bgr;-alanine diacetic acid, S,S-ethylenediaminedisuccinic acid, iminodisuccinic acid, hydroxyiminodisuccinic acid, any salt thereof, any derivative thereof, and any combination thereof. The treatment fluids can optionally comprise an acid, which can include hydrofluoric acid or a hydrofluoric acid generating compound.
