Of critical importance in the proper application of inhibitors within oil producing wells is the delivery of the chemical throughout the system. In traditional batch treatment, an excess of chemical is required to ensure a sufficient quantity of corrosion inhibitor is applied to all metal surfaces. The performance of the chemical and retreatment interval are based upon film persistency. The results of two field trials using a novel batch treatment using slow release (mass transfer controlled) solid corrosion inhibitors is presented. Using an encapsulated batch treatment, the chemical performance and retreatment interval are based upon inhibitor concentration in the system. The total chemical usage decreases and the treatment interval increases twelve-fold.
