Charpy Impact Requirements for Carbon Capture and Storage (CCS) Wells Using CRA Alloys

This paper presents the second part of the collaborative study on the qualification of carbon steel and CRA material grades for CCS wells injection service following AMPP2023 publication C2023-18760 for CO2 injection casing. In this paper the focus is on the CRA alloy tubing for CO2 injection. The Charpy impact testing and fracture mechanics CTOD testing was performed on representative high strength 25Cr CRA alloys of 80 ksi and 125 ksi grades to provide data for validation of the BS 7910 Annex J Master curve procedure for converting Charpy impact values to fracture toughness. The study showed that BS 7910 Annex J Master curve model can be applied to high strength OCTG 25Cr CRA grades. An example case study is presented for an injection tubing showing that the API 5CRA requirements for Group 2 materials appear to be sufficient for the accidental load scenarios considered in CO2 injection well design.
