/Composition And Methods For Inhibiting Corrosion Of Metal During Acidizing A Wellbore In A Subterranean Formation For Fracking
Abstract

An acid composition for acidizing a wellbore including an acid, an acetoxystyrene, and a polycyclic diquaternary quinoxaline. A method of using the acid composition. A method of forming a hydrocarbon-bearing formation for a stimulation operation including injecting the acidic composition into a wellbore so that the acidic composition is indirect contact with a perforation tool, a wireline and a wellbore casing, allowing the acidic composition to come into contact with a first perforated area and a first cementitious debris for a predetermined period of time to prepare the formation for a stimulation operation, and allowing the acidic composition to come into contact with a second perforated area and a second cementitious debris for a predetermined period of time to prepare the formation for the stimulation operation.
