Mechanical failures can occur in a well for a variety of reasons. They are usually related to one of the following: (1) the corrosion of downhole equipment, (2) the collection of debris or scale in the wellbore, (3) the production of formation sand or collapse of the formation, (4) insufficient cement protection, or (5) the use of equipment that is not designed to withstand the depth, temperature, or pressure of a well.
