Abstract: Fluid compositions comprising water, an acid or an acid source, a chelating agent and a relative permeability modifier have utility in the context of matrix acidizing of oil bearing sandstone formations. Acidizing treatments with these compositions may improve the formation permeability to oil with respect to the permeability to water. The relative permeability modifier is a cationic polyacrylamide.
Abstract translation: 包含水，酸或酸源，螯合剂和相对渗透性改性剂的流体组合物在含油砂岩地层的基质酸化的背景下具有效用。 使用这些组合物的酸化处理可以提高对水的渗透性对油的地层渗透性。 相对渗透性改性剂是阳离子聚丙烯酰胺。

Abstract: A composition and method for performing a treatment of a subterranean formation. The composition includes an emulsified acid and a sulfobetaine surfactant. The emulsified acid and the sulfobetaine surfactant may be mixed to form a treatment composition, which may be injected into a subterranean formation as part of an acid fracturing or hydraulic fracturing treatment.
Abstract translation: 一种用于进行地下地层处理的组合物和方法。 该组合物包括乳化酸和磺基甜菜碱表面活性剂。 乳化酸和磺基甜菜碱表面活性剂可以混合以形成处理组合物，其可以作为酸压裂或水力压裂处理的一部分注入到地下地层中。

Abstract: A cement slurry composition is described as having cement, water, and organic polymeric particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propyxlate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry and to reduce or prevent foaming. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set into a solid mass in the zone.
Abstract translation: 水泥浆组合物被描述为具有水泥，水和有机聚合物颗粒。 组合物还包括非离子表面活性剂，其可以在亲水部分中含有乙氧基化物基团或含有乙氧基化物基团和丙酸酯基团。 非离子表面活性剂用于将疏水性聚合物颗粒分散在浆料中并减少或防止起泡。 制备水泥浆组合物，然后泵送到地下井中并置于地下井的一个区域中。 然后允许水泥浆料组合物在该区域中固化成块。

Abstract: A method of treating a subterranean formation, the method including placing a well treatment fluid comprised of at least an enzyme and a breaker additive in the subterranean formation. Initially, the pH of the well treatment fluid is about 11.5. The breaker additive reduces the pH of the well treatment fluid by at least 1.5 to increase the activity of enzyme and accelerate hydrolysis of a crosslinkable component.
Abstract translation: 一种处理地下地层的方法，所述方法包括将至少包含酶和破坏剂添加剂的井处理流体放置在地层中。 最初，井处理液的pH值约为11.5。 破碎剂添加剂将井处理流体的pH降低至少1.5以增加酶的活性并加速可交联组分的水解。
