This paper describes the improvements of a software program developed for the materials selection of OCTGs and well completion components. The previous version of the program released in 1998 and presented during 1997 and 2000 NACE Conferences has been reviewed in terms of technical know-how and information technology to keep up with the modern industry. The most remarkable improvements in the field of technical know-how include the introduction of a number of well completion layouts the management of other types of fluids and well services in addition to reservoir fluids and hydrocarbon production service the development of a pass/fail approach for the selection of CRAs for sour service the formulation of rules to help the corrosion engineer to select the most suitable test methods and test conditions and the addition of new materials grades that become market available in the last ten years. The improvements the information technology experienced also led to the development of a new software framework for the program. The new product is a web application accessible from the Company intranet network and it is a shared tool that employees can use with different levels of authorizations reflecting their own skills and technical competences. Corrosion experts also have the chance to install a “local version” of the software on their laptops and subsequently to synchronize all the data with a centralized database. Plain users are allowed to a limited access to the program functionalities while users qualified as corrosion experts have the credentials to modify the software basic rules. Administrators can “publish” users’ simulations on a centralized public library. In brief this paper wants to remark how the concept of “expert system” born during the late 80s and developed during the 90s is not out-of-date in the modern industry but on the contrary it is still topical and it has changed its shape in the last 20 years thanks to the improvements on information technology and industry know-how.
