New CentrAce Centralizer

New CentrAce Centralizer

Developed in partnership with Ace Oil Tools, the CentrAce is an innovative new product created for Deepwater wells. It combines a low profile Ace stop collar with a close tolerance Centek centralizer. It is designed for use in deepwater tight tolerance applications as an over pipe, pulled in, rotational method of centralization thus reducing the dependency on subs. It is also well suited for use in under-reamed applications and ideal for wash-out sections, as the centralizer OD is over sized, or, as a simple unit of choice when running standard OCTG casing sizes.
