In directional wells, proper casing centralization is essential to ensure proper cement bonding. CENTRA calculates centralizer spacings for any directional well. Casing deflection and centralizer properties are considered to predict casing stand-off, centralizer spacing, and hook loads for running casing.

A variety of options are provided for designing centralizer placement.
The output illustrates centralizer placement and spacing, as well as hook loads during cementing.
The Sensitivity utility compares the impacts of changes in fluid weights, friction factor, and casing weight. |
