Centek pursues deepwater growth for centralizers

Offshore staff

NEWTON ABBOT, UKCentek Group has formed a Deepwater Division to further development of its deepwater centralizer products.

The centralizers are designed for use in wells where up to nine casing strings can be running through each other, so tolerances are tight.

The systems have to compress fully to travel through the tight casing strings and to then expand, undamaged, to the designed open-hole size in order to centralize the casing.

Once in position the centralizers provide stand-off and fluid displacement optimized to improve well clean-out.

Their low coefficient of friction, Centek adds, allows casing to be reciprocated and rotated, improving mud removal and cement displacement and contributing to a solid cement bond and long-term zonal isolation.
