Corrosion control in the oil industry is a matter of economics. Up to 1% of the overall operating costs could be saved through corrosion management. All too often this is not considered and corrosion monitoring only occurs on a need to know basis after an unscheduled shutdown or actual casing failure. Corrosion management involves casing inspection and periodic monitoring, corrosion rate prediction and cathodic protection evaluation. Today’s corrosion wireline logging tools offer a technique to predict and detect potentially disastrous corrosion problems.

Current wireline measurements utilize electromagnetic, flux leakage, ultra- sonic and mechanical techniques. They can predict, detect and delineate corrosion in the form of metal loss, holes, pits, and mechanical deformation. Furthermore, external problems can be distinguished from internal ones. These measurement systems will be briefly described along with examples of multiple measurement diagnostics.
