Oilfield Corrosion Management-RILS

Corrosion Principles and Classification 

• Corrosion impact
• Thermodynamic and kinetic factors
• Corrosion classification

Day one of this course will focus on corrosion principles and classification.  Participants will learn about the corrosion impact in oil and gas production systems, along with the main issues of corrosion.  Corrosion principles will be covered including thermodynamic and kinetic factors in aqueous corrosion systems.  The day will end with participants learning about corrosion classifications, such as general or uniform corrosion, localized corrosion, mechanical assisted degradation, and environmentally induced cracking.

CO₂ and H₂S Corrosion

• CO₂ and H₂S corrosion     

Day two will start off with participants learning about CO₂ and H₂S corrosion, this will include the corrosion mechanism, factors affecting the corrosion rates, condition for the corrosion, and prediction.

Corrosion Inhibition

• Inhibitor fundamentals, guideline, and selection
• Methods of application

Material Selection 

• Material selection guidelines
• Typical materials used for downhole equipment, tubing and pipeline
• CRA, GRE, and carbon steel comparison

On day three, participants will learn about material properties, oil and gas fluid resistance, and selection.  They will learn typical materials used for downhole, low alloy steel, Corrosion Resistant Alloy (CRA), and guidelines for downhole tubular material selection.  CRA, GRE, and carbon steel comparison will also be covered, with special attention to the costs, advantages, and limitations of each.

Erosion 

• Calculating erosion rate
• Erosion by non-corrosive fluids
• Corrosion-Erosion   
  

• Types of corrosion and control methods
• External protection
• Exercises and case studies   

The last day will cover the erosion concept, case studies for well, pipeline and plants.  The day end with the pipeline external corrosion, types of external corrosion present in pipelines, control methods,  NACE RP 0502-2002 “Pipeline External Corrosion”, along with risk based inspection and pipeline integrity management.
