The Centralizer placement Module (Centralizer) optimizes the centralizer position during cementing as per SYT5334 and API Spec 10D. The software can analyze whether the centralizer and the casing interval are installed in the middle place, automatically optimize the centralizer position, support complex conditions like electric logging and support a number of centralizer installation modes. Centralizer has complete built-in centralizer database and allows users to add customized data.
