Gives 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 10% (molar) of CO[2] and 1 MPa CO[2] partial pressure].

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 10% (molar) of CO ₂ and 1MPa 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.
