Corrosion Management in Production Process Operations

Introduction

This course will cover the main causes of corrosion in upstream oil and gas operations, as well as monitoring and mitigation methods. The various corrosion mechanisms give rise to a number of different forms of corrosion damage which will all be considered. Participants will estimate the corrosively of a given environment through the analysis of the chemical and physical characteristics of the system. You will select materials and coatings for corrosion resistance for different conditions and applications, including the use of NACE MR0175. You will also conduct CP surveys, select the system type, estimate current requirements, and design simple cathodic protection systems. There will be an opportunity to select and utilize corrosion inhibitors for different systems and Course Outcomes on how to select and apply corrosion monitoring techniques to create an integrated monitoring program.

The Course Outline is based on a field facilities engineering point of view as opposed to a more narrowly specialized corrosion engineering or chemistry viewpoint. This course provides an appropriate balance of necessary theory and practical applications to solve mitigate corrosion-related problems.
