Casing centralization is one of the key elements to ensure the quality of a cementing job. It does so by preventing mud channeling and poor zonal isolation. While centralizers are used extensively, well problems continue to arise due to poor cementing jobs. The challenge that both operators and service companies face is to choose the right type of centralizers and place the correct amount of them in the optimum position on the casing to achieve a good standoff profile.

PVI's CentraDesign optimizes the centralizer placement, predicts casing standoff and torque and drag for ERD or deviated wellbores. It determines the number and placement of centralizers using one of the four modes: "specify spacing", "specify location", "specify standoff" and "optimum" for bow-spring, rigid, semi-rigid, and mold-on centralizers.

With extensive knowledge in engineering mechanics as well as extensive collaboration with centralizer vendors, PVI provides both service companies and operators with the most sophisticated yet easy-to-use solutions to ensure the quality of a cementing job.

    CentraDesign Lite is a casing centralization app for both Android and iOS devices. This application is a condensed version of CentraDesign, our centralizer placement software. CentraDesign Lite includes bow spring and rigid centralizers and provides centralizer and casing databases. This app calculates one span of casing standoff and clearance using any combination of hole, pipe size and inclination angle. It also takes buoyancy and side force effect into consideration. The output results include standoff and clearance at centralizer and mid span. Users are also able to view the casing deflection in 2D and 3D view.
