Details of a new tool are presented for monitoring real time corrosion in downhole situations. This battery-powered data logging systems generates continuous corrosion history, which is transfered to a PC for analysis. A case study of this Downhole Corrosion Monitoring System (DCMS) is described. The tool is set at any required well depth, and is sensitive enough to show the period of inhibitor film persistency, effectiveness of different treatment chemical and application methods, enabling a realistic economic assessment to be made.
