ABSTRACT
This paper reflects our experience of the design and use of a new expert system for Cementing preparation aid.
The quality of casing cementing is important in ensuring the long lived productivity of a well. It is therefore essential to ensure a good preparation of this delicate job. The know-how of the trade completed by the calculations to be taken into account are gathered in one same system which offers to the user an optimized solution with respect to his restraints.
This expert system called CIMENTEX is intended for the field operators and allows us to pass on the rules of the art and to improve it with field experience, by feedbacks.
The aim of this software is also to give rise to the user's reflections and critical remarks which are necessary to enhance the cementing technique.
This is made possible because of the time saved on preparation and the opportunity to perform the same inquiry over again very quickly.
This expert system was first validated in the Drilling-Completion central services then in three subsidiaries of our Group. It is now operational in its initial aid release fot the preparation of production and intermediate casing cementing.
