Well Casing Cathodic Protection Course
Introduction:
Cathodic Protection (CP) is an effective method of corrosion mitigation for metallic structures that are buried, submersed, or in contact with (i.e. tank bottom) an electrolytic environment. Corrosion is an electrochemical process by which oxidation occurs on the surface of an anode when placed in a common electrolyte with a cathode and physically adjoined via an electrical conductor.
Course Objectives:
This course focuses on the principles and procedures for Cathodic Protection (CP) design on a variety of structures for both galvanic and impressed current systems. The course discusses theoretical design concepts, considerations that influence the design (environment, structure type materials of construction, coatings), design factors, and calculations (including attenuation).
Who Should Attend?
This program will benefit anyone who is responsible for well casing Cathodic Protection, measuring the effectiveness of Cathodic Protection systems and/or recording this data, including well Operations engineers, Corrosion Engineers, Materials Engineers, Design Engineers, Mechanical Engineers, Inspection Engineers, Chemical Engineers, Marine Maintenance people, Offshore Structure design and Operation people, CP field personnel, technicians, and supervisors.
