Key performance indicators are used to track the efficiency of the prevailing corrosion risk management strategy namely the integration of corrosion process monitoring inspection mitigation environmental control and materials management. In an earlier paper a methodology was outlined for the use of a single key performance indicator namely the corrosion rate in tracking monitoring strategy mitigation strategy and pipeline integrity. This paper seeks to identify other key performance indicators.At Kuwait Oil Company (KOC) Internal Corrosion Monitoring activities are carried out in 22 Gathering Centers Early Production Facilities 5 Booster Stations (operating) 3 Effluent Water Disposal Plants Seawater Treatment Plant Seawater Injection Plant and pipeline network carrying different products. Corrosion and corrosivity trends are monitored using Corrosion Coupons Corrosion Probes Bioprobes Hydrogen Patch probes Galvanic probes as well as the measurement of Iron Content (total and dissolved) and Manganese Content. Corrosivity trend is also monitored using pH conductivity Total Dissolved Solids Total Hardness Dissolved Oxygen Hydrogen Sulfide concentrations Carbon Dioxide concentrations Bacteria population density and Corrosion Inhibitor residuals. These activities consume significant resources. The present paper is focused on identifying parameters that could serve as key performance indicators and enable the company to operate with greater cost effectiveness efficiency reliability and control of the state of corrosion integrity of Oilfield Water Handling Systems.Key words: Key Performance Indicator (KPI) Corrosion Control Metrics Corrosion trend Corrosivity Trend Corrosion Integrity.
