ABSTRACT:
A multi part centralizer can be secured quickly to tubular to be cemented and expanded in a deviated wellbore. The segments ratchet with respect to each other and are capable of holding the centralizer snug against the tubular for delivery downhole and cementing. After cementing the expansion of the tubular is not significantly resisted by the centralizer as its diameter increases with the expanded tubular below it. The end position after expansion is held due to the ratchet feature insuring the fixation of the centralizer as the cement sets.
