Centek Centralizer | Centek UROS centralizers improve stand-off in washed out hole sections of HPHT well THE CHALLENGE Centralizer stand-off can be critical in achieving effective zonal isolation during primary cementing operations. When encountering unconsolidated formations, and when available caliper logs show washed out hole sections on critical high pressure, high temperature wells, it can be a challenge to find the right centralizer product to match the well bore environment. Running a centralizer at hole gauge will obviously offer less stand-off in washed out areas. Running over gauge centralizers can cause increased drag and possibly not fit through the well bore restrictions of sub surface well heads and the IDs of previous set casings.
