1. n. [Enhanced Oil Recovery]

A type of batch-treating technique used in corrosion control. The batch of corrosion inhibitor is displaced through the annulus to the bottom of the well. Once the inhibitor is at the bottom, it is circulated up the tubing and returned back into the annulus, leaving a considerable amount of inhibitor in the annulus for further circulation. A standard batch treatment is used mainly in pumping wells and could last from a day to several months depending on the specific corrosion inhibitor used.
