1. n. []

A chemical agent used in stimulation treatments to ensure uniform injection over the area to be treated. Diverting agents, also known as chemical diverters, function by creating a temporary blocking effect that is safely cleaned up following the treatment, enabling enhanced productivity throughout the treated interval. In matrix acidizing of injection wells, benzoic acid is used as a chemical diverter, while oil-soluble resins are employed in production wells. Both compounds are slightly soluble or inert in the acidic medium [HCl], but after functioning as diverters, they dissolve with water injection or oil production, respectively. Stable, viscous foams generated in the rock matrix are also considered to be chemical diverters.
