The partitioning of a corrosion inhibitor between the oil and water phases has a significant impact on inhibitor selection, treatment philosophy, and inhibitor transport. This work was undertaken to develop information on how inhibitor concentration varies with treatment rate and operational conditions. It was found that partitioning of the selected inhibitor
varied by several orders of magnitude dependent on the water cut. With a low water cut, the tested corrosion inhibitor partitioned preferentially into the water phase, and with a high water cut, the inhibitor partitioned into the gas condensate phase. These issues are discussed with respect to laboratory and field measurements.
