Centek Centralizer | Rugged Centek Centralizers enable casing rotation during cementing operations In a 3 well comparison in Oklahoma, USA, Centek Centralizers are proven to aid rotation, enhancing uniform annular cement placement. THE CHALLENGE Casing reciprocation in the past has been performed for most cementing cases. Today’s drilling technology with top drive rigs now gives the added opportunity of casing rotation, and with the correct cementing heads, can also include simultaneous reciprocation. Rotation also helps with fewer side effects on ECD’s (Equivalent Circulation Density). With rotation operations being performed, the centralizers on the casing string have to be rugged enough to stand up to these procedures. Typical standard welded hinged bow spring centralizers are no
