Abstract
Japan National Oil Corporation (JNOC) and Nippon Steel Corporation (NSC) developed a material selection software program, called J-Tube Mate, to select corrosion-resistant alloys for tubular goods based on assessment of corrosion resistance and total cost of materials. We confirmed the reliability of this program by comparing the calculated data with the available field data. This program can be used as a tool to do screening study of the cost-effective well design in corrosive environment (i. e. carbon dioxide and hydrogen sulfide).
