DIN Standards Committee Petroleum and Natural Gas Industries

Overview

This International Standard contains 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. This International Standard 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. For Germany, Working Group NA 109-00-01-80 AK "Materialien, Korrosionsüberprüfung, Schweißen und Verbinden sowie zerstörungsfreie Prüfung"("Materials, corrosion control, welding and jointing, and non-destructive examination") at DIN Standards Committee Petroleum and Natural Gas Industries (NÖG) has participated in preparation of the standard.
