Abstract
Increased demand for energy has led to O&G exploration and production in some very challenging environments in particular, under high pressure high temperature conditions. This has led to significant changes in design philosophy which is more focused on damage tolerance. The above changes have challenged the materials and corrosion community to understand and quantify environmentally assisted cracking of steels of range of materials from steels to high strength nickel based alloys. This challenges associated with developing test methods to generate design information in sour service and seawater environments will be discussed along with an attempt to understand the underlying that may be applied to develop predictive tools.
