AN INTRODUCTION TO CORROSION AND PROTECTION OF CASING

Corrosion is defined as the chemical degradation of metals by reaction with the environment. The destruction of metals by corrosion occurs either by direct chemical attack at elevated temperatures (500+°F) in a dry environment or by electrochemical processes at low temperature in a water-wet or moist environ­ment..

Corrosion attacks casing during drilling and producing operations through elec­trochemical processes in the presence of electrolytes and corrosive agents in drilling, completion, packer and production fluids.
