WELLCARE Centralizer Software program providesoptimum deployment (minimum strategic deployment for maximum output) ofcementation products in the well.The Program works with actual well data, including well profiles and pipe data to calculate down hole forces. It then analyses actual WELLCARE Centralizer performance data to determine where to place specific equipment so that a minimum stando ff is maintained throughout the string. The Program is sophisticated enough to devise a complete equipment installation design by taking pay zone area or other specialized areas into account. While WELLCARE Centralizers give perfect bore performance, the Centralizer Software Program confirms it before application. 25
