Corrosion In Drilling Operations

Discusses the problems, solutions, & current developments in the phenomenon of drilling operation corrosion.

Corrosion, in terms of drilling operations, was responsible for at least 70 billion dollars in losses in 1975, or 4% of the gross national product. Reportedly, 10 to 45% of that loss was preventable (Bertness and Chilingarian, 1983, 559). Understanding the causes of corrosion in terms of drilling operations is?tantamount to saving time and money. The trends towards drilling of deeper wells, the use of higher strength steels, the presence of higher stress levels and the use of lower pH drilling fluids all contribute toward increased corrosion susceptibility.
The destruction of metals by corrosion is caused by direct (…)
