Abstract: An aqueous acid composition that may be used, for example, in a matrix acidizing treatment can include an acid, a polymeric acid corrosion inhibitor, and an acid corrosion inhibitor intensifier. The acid corrosion inhibitor can include iodide ions and metal ions, with the metal ions being one or more of copper, silver, bismuth, or antimony. The molar ratio of metal ions to iodide ions can be 1:X, where X is greater than or equal to 2. The polymer of the polymeric acid corrosion inhibitor can have a molecular weight less than 100,000 g/mol.

Abstract: Corrosion of steel in acidic solution is inhibited using a mixture of a compound in which a plurality of heterocyclic aromatic groups with a quaternary nitrogen atom are connected together, such as by a linking group which may be covalently attached to the quaternary nitrogen atoms of the aromatic heterocyclic rings, and a polarizable adsorption-intensifying anion.

Abstract: The present invention provides aqueous viscoelastic compositions comprising a cleavable surfactant and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise at least one weak chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscoelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscosifying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations. Thus, the present invention also relates to a wellbore service fluid and a method of fracturing a subterranean formation. The present invention also concerns novel cleavable surfactants.

Abstract: A wellbore fluid comprises an aqueous carrier liquid, hydrophobic fibers suspended therein, hydrophobic particulate material also suspended in the carrier liquid, and a gas to wet the surfaces of the particles and fibers and bind them together as agglomerates. The wellbore fluid may be a slickwater fracturing fluid and may be used for fracturing a tight gas reservoir. Using a combination of hydrophobic particulate material, hydrophobic fibers and gas inhibits settling out of the particulate material from an aqueous liquid. Because the gas acts to wet the surfaces of both materials and agglomerates them, the particulate material is made to adhere to the fibers; the fibers form a network which hinders settling of the particulate material adhering to them, and the agglomerates contain gas and so have a bulk density which is less than the specific gravity of the solids contained in the agglomerates.

Abstract translation: 井眼流体包括水性载体液体，悬浮在其中的疏水性纤维，还悬浮在载体液体中的疏水性颗粒材料，以及将颗粒和纤维的表面湿润的气体，并将其作为附聚物结合在一起。 井筒流体可以是一个滑水压裂液，并可用于压裂一个紧密的气藏。 使用疏水性颗粒材料，疏水性纤维和气体的组合可以防止从水性液体中沉淀出颗粒物质。 因为这些气体用来润湿两种材料的表面并使它们聚集，所以使颗粒材料粘附到纤维上; 纤维形成阻碍粘附在其上的颗粒材料的沉降的网络，并且附聚物含有气体，因此其堆积密度小于附聚物中所含固体的比重。
