Petroleum and natural gas industries. Materials selection for high content CO<sub>2</sub> environment for casings, tubings and downhole equipment
This International Standard provides guidelines and requirements for material selection of both seamless casing and tubing, and downhole equipment for CO 2 gas injection and gas production wells with high pressure and high CO 2 content environments [higher than 10Â % (molar) of CO 2 and 1Â MPa CO 2 partial pressure]. Oil production wells are not covered in this International Standard. This International Standard only considers materials compatibility with the environment.
Guidance is given for the following:
corrosion evaluation;
materials selection;
corrosion control.
This International Standard is aimed at high CO 2 content wells, where the threat of low pH and CO 2 corrosion is greatest. However, many aspects are equally applicable to environments containing lower CO 2 concentrations.
Materials selection is influenced by many factors and synergies and should be performed by either materials or corrosion engineer.
