A composition including HCl, urea, complex substituted keto-aminehydrochloride, an alcohol, an ethoxylate, and a ketone is provided in a method for solubilizing calcium carbonate in an aqueous suspension or dispersion of calcium carbonate. 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. |
