ISO 17348:2016

Petroleum and natural gas industries — Materials selection for high content CO2 for casing, tubing and downhole equipment

ISO 17348:2016 provides guidelines and requirements for material selection of both seamless casing and tubing, and downhole equipment for CO₂ gas injection and gas production wells with high pressure and high CO₂ content environments [higher than 10 % (molar) of CO₂ and 1 MPa CO₂ 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.

ISO 17348:2016 is aimed at high CO₂ content wells, where the threat of low pH and CO₂ corrosion is greatest. However, many aspects are equally applicable to environments containing lower CO₂ concentrations.

Materials selection is influenced by many factors and synergies and should be performed by either materials or corrosion engineer.
