    摘要: Method of treating a subterranean formation using a hydrocarbon treatment fluid using a phosphor-based hydrocarbon gelling agent that is capable of both increasing the viscosity of the hydrocarbon treatment fluid and remaining in the subterranean formation after the viscosity of the gel is broken such that it can act as a scale inhibitor. Phosphor-based hydrocarbon gelling agents may be formed from a polyvalent metal salt of an organophosphonic acid ester or from a polyvalent metal salt of an organophosphinic acid.

    摘要: Treatment fluids containing biodegradable chelating agents and methods for use thereof are described. 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, β-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.
