Failure of production tubing in the oil & gas industry has become alarmingly more frequent in recent years in spite of the increased use of corrosion-resistant-alloy (CRA) materials. The majority of the recent failures have occurred from the outside (annulus side) and been attributed to Environmentally Assisted Cracking (EAC) — hence, best described as Annular EAC (AEAC). Examination of these failures points to a serious incompatibility of the production tubing metallurgy with the packer fluid under stress. To solve this problem, a research alliance of the co-authors to examine the compatibility of a wide spectrum of completion fluids with various martensitic stainless steel metallurgies was established.
