It is important to know the cause of sucker rod failures so that the cause can be eliminated or guarded against. This paper presents numerous illustrations of the most common forms of sucker rod failures and explains the cause of these failures. Corrosion is the greatest cause of sucker rod failure and the bulk of the illustrations are of sucker rods that have been damaged by corrosion. A brief description of the basic corrosion process is included.
