Transport of corrosion inhibitor to the location where they are needed is one of the primary concerns in the use of corrosion inhibitors. Two different types of inhibitors for controlling CO2 corrosion in gas well wellheads and flowlines are used as examples. In one example, the inhibitor forms a micelle in water which assists in the transport of inhibitor to the metal surfltce. In the other example, the inhibitor is readily dispersible in the water phase but must be stirred to ensure transport of the inhibitor to the metal surface. Field monitored corrosion rates using continuous application of inhibitor are presented for both types of inhibitor.
