1. n. [Perforating, Well Completions]

An acid treatment placed in the wellbore over the interval to be perforated. Because of the overbalance conditions at the time of perforating, the perforating acid is forced into the newly formed perforation tunnel to stimulate the crushed zone. Formulation of the perforating acid depends on the characteristics of the formation and the downhole equipment used.
