Corrosion Control in Oil and Gas

Overview:

Introduction:

This training program provides deep knowledge of corrosion and focuses on the examination and identification of metallurgical problems that occur in process units and methods of monitoring and damage reduction. It utilizes the application of engineering principles and procedures to minimize corrosion to an acceptable level by the most economical method.

Program Objectives:

At the end of this program, participants will be able to:

• Explore the materials of construction used in the oil, gas, and water fields.
