Course Overview:
This course describes corrosion engineering in relation to oil and gas production.
It discusses corrosion control methods, regulatory and safety aspects, and the significance of a monitoring and inspection program. Participants will learn the cost of corrosion including loss in production, repairs and materials as well as corrosion control measures such as inhibitors, cathodic protection and design concepts.
The course targets engineers, inspectors, and personnel involved in R&D departments of the oil and gas industry as well as service company personnel offering corrosion control services.
Corrosion aspects caused by oxygen, hydrogen sulfide, carbon dioxide, and bacteria and elimination of these aspects describing practical case studies and failures are included.
Course Objectives:
Upon completion of this course, you will gain an understanding of corrosion engineering in oil and gas production involving the various methods available for corrosion control, regulatory and safety matters, and the contribution of an integrated monitoring and inspection program for operations and diagnosis of problems.
Who Should Attend?
The course is designed essentially for process and mechanical engineers employed by the operating companies engaged in oil and gas production. The material is also appropriate for those personnel concerned with special functions in the oil industry including inspection, material selection, and corrosion control, as well as those involved in R&D.
The staff of service companies providing corrosion inhibitors and overall corrosion services should also find this course beneficial, together with companies or manufacturers’ marketing materials, coatings and equipment for cathodic protection, inspection (NDT) and corrosion monitoring.
