Claim One:
1. A method for well integrity management using a coupled engineering analysis, which comprises: a) performing a drilling engineering analysis based on a temperature and a pressure for a well during drilling operations using a computer processor, wherein the drilling engineering analysis determines a casing integrity, a wellbore integrity, a surface equipment integrity and a drillstring integrity; b) performing a completion engineering analysis based on a temperature and a pressure for the well during completion operations using the computer processor, wherein the completion engineering analysis determines a casing integrity, a tubing integrity, a surface equipment integrity and a completion string integrity; and c) performing a production engineering analysis based on a temperature and a pressure for the well during production operations using the computer processor, wherein the production engineering analysis determines at least one of a metal loss, a type of corrosion, a tubing yield strength, an erosion velocity and an erosion rate.
