Fourthly, thirty-day tests of uniaxial tensile specimens were conducted to check for SSC susceptibility. Thirdly, slow strain rate testing was used to screen the conditions. Secondly, the testing matrix was defined to determine actual casing exposure conditions. First, the casing material was tested to judge whether its properties were normal. This work aims to determine the material qualification of 13Cr-L80 casing for sour conditions which is of great importance to check the sulfide stress cracking susceptibility, confirm the range of applicable conditions and recommend anti-corrosion materials.
