acid inhibitor

1. n. [Well Workover and Intervention]
A chemical additive used to protect wellbore components and treatment equipment from the corrosive action of an acid. The type and concentration of acid inhibitors are determined by the type of metal to be protected and the specific wellbore conditions, such as temperature and the length of exposure time anticipated during the treatment. To ensure efficient protection, the inhibitor should be consistently blended throughout the treatment fluid.
