A 125ksi grade high strength low alloy steel OCTG has been developed for mildly sour environments. This has been used as a ‘fit for purpose’ production casing material in high pressure/high temperature wells.
The prevention of oxygen ingress and pH stabilization during testing have been investigated for obtaining accurate SSC resistance results by NACE TM0177-2005 Method A in mildly sour conditions. New testing techniques have been developed in which the test equipment is contained within a nitrogen chamber and the test pH is stabilized by using an acetic acid/sodium acetate buffering system.
The SSC resistance of 125ksi grade high strength low alloy steel has evaluated using the enhanced testing technique under various H2S partial pressure and pH conditions. The SSC resistance limits are discussed in the relationship between H2S partial pressure and pH.
