No. 8,430,971, issued Apr. 30, 2013, which itself is a divisional application of U.S. patent application Ser. No. 13/104,180, filed May 10, 2011, now U.S. Pat. No. 8,163,102, issued Apr. 24, 2013, which itself is a continuation-in-part patent application of U.S. patent application Ser. No. 12/419,379, filed April 7, 2009, now U.S. Pat. No. 7,938,912, issued May 20, 2011, the disclosures of which are herein incorporated by reference in their entirety, and all commonly owned.
[0002] The present invention relates to compositions and methods for treating fluids, and, more particularly to such compositions and methods for treating drilling fluids in industrial applications, hydraulic fracturing, solubilizing elements, and lowering salts.
[0003] The removal of water-insoluble cementitious and lime materials from surfaces is known to be a difficult process. Compositions that have been known for use in the past have included acid (e.g., hydrochloric, hydrofluoric, phosphoric, and sulfuric) washes and urea hydrochloride solutions.
[0004] However, the solutions known in the art can cause corrosion and flash rusting to metal and metal alloy surfaces, and also can dissolve away surface coatings and underlying metals. Thus, the use of such compositions can decrease the life of a surface and its coating significantly. For example, when used on vehicles and other industrial and construction equipment, such compositions can greatly increase the frequency at which the treated surfaces must be re-painted, re-coated, or re-sealed.
[0005] Additionally, many prior known compositions are not environmentally safe, and contain components that are non-OSHA and -EPA compliant. Some jurisdictions have regulations as to materials that can be drained so as to ultimately reach ground water. Resource Conservation and Recovery Act (RCRA) metals are among those substances that are regulated, and include arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. As an example, chromium is often used as a lustrous coating on bumpers, mirrors, hydraulic rams, and trim parts on vehicles such as concrete trucks. Since construction equipment is typically washed outdoors, the resulting process water usually drains directly into the ground, and, thus, if the equipment is coated with an RCRA or other undesirable material that can be released with the washing composition, the material will enter the groundwater.
[0006] Therefore, it would be beneficial to provide a composition and method of use that are effective at removing cementitious materials from surfaces without causing corrosion or rusting, which can damage the target surface and release harmful substances such as RCRA materials into the environment. Preferably the composition should also include components that are environmentally safe and OSHA- and EPA compliant.
[0007] It would also be beneficial to provide an environmentally safe composition and method of use that are effective in assisting in performing hydraulic fracturing of an oil gas well, adjusting and maintaining the pH of process water and other fluids in industrial applications, and solubilizing calcium carbonate in an aqueous suspension or dispersion thereof.
[0008] The application provides a method for pickling treatments, electronic submersible pump treatments (ESPs), hydraulic fracturing, perforation cleaning and debris removal, toe preparation treatments that replace the use of acetic acid blends, cement squeeze treatments, injection well treatments, disposal well treatments, pH adjustment of recycled frac water and/or flow-back fluids, pH adjustment fluid to assist with the hydration of gelled based systems, breaking gelled fracturing systems to replace the use of dangerous oxidizing agents, using a fluid to unstick a drilling rig, acid fracture, spearhead acid squeeze soaking, and filter cake removal comprising: solubilizing calcium carbonate in an aqueous suspension or dispersion of calcium carbonate, the method including the steps of i) providing a composition comprising HCl, urea, complex substituted keto-amine-hydrochloride, an alcohol, an ethoxylate, and a ketone; ii) adding the composition to an aqueous suspension or dispersion of calcium carbonate; and iii) permitting the composition to solubilize the aqueous suspension or dispersion of calcium carbonate.

[0014] A method of using the composition includes applying the composition to a surface to release a cementitious material therefrom and removing the composition and released cementitious material from the surface.
[0015] The composition comprises an organic, cationic inhibitor for both corrosion and flash rusting that minimizes pitting and attack on metal and alloy surfaces, such as are common in construction equipment and trucks. As the composition is non-corrosive to metals, it has been deemed non-regulated by the U.S. Department of Transportation (DOT), and is environmentally safe and OSHA- and EPA-compliant. The composition has been shown to reduce corrosion levels to well below the DOT corrosion limits of 6.25 mmpy.
[0016] In an exemplary embodiment, the inhibitor, which is used at a level of approximately 0.5% in the composition, comprises 10-30% surfactant, 10-30% complex substituted keto-amine-hydrochloride, 1-10% 3-methyl butynol, 1-10% isopropyl alcohol, 1-10% methyl vinyl ketone, and < 1% acetone.
