Abstract

A method of determining susceptibility of an alloy to environmental cracking in a wellbore environment including exposing the alloy to high pressure high temperature sour dense gas with specified relative humidity in a test apparatus; measuring the amount of environmental cracking resulting in the alloy; and tuning a thermodynamic model based on the measured environmental cracking of the alloy.
