Description / Abstract:

This international standard provides guidelines for material selection of seamless casing and tubing and downhole equipment of CO2 gas injection wells and production wells in high pressure and high content CO2 environments (above 10 % m olar o f CO2 and 1 MPa o f CO2 Partial pressure). This international standard only considers materials compatibility with the environment.

Guidance is given for the following:

— corrosion evaluation;

— materials selection;

— corrosion control.

The guidance in this standard is aimed at high CO2 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 an experienced materials engineer.
