WellChek Database has been developed to provide a well specific, tubing string profile from an on-site used tubing inspection unit. Tubing is classified as it is pulled from the well, providing sequential information on a per joint basis within the string. Before being returned to production a detailed report of the tubing string is provided online, which can be viewed together with previous inspection results, containing critical information to the well management program. Routine well maintenance provides the opportunity for inspection data to be easily obtained. Field engineers find it beneficial to track wear and corrosion patterns, propensity, failure causes and success of mitigation techniques. Tubing issues make up a high proportion of production costs - rig time, lost production, tubular replacement and transportation. Working together with production engineering groups to analyze this data has yielded information to assist in making practical tubing management policies to reduce these costs.
