Centek announces Deepwater Division


Centek Group, the leading centraliser manufacturer, has formed a Deepwater Division to focus the sale and support of its specialist deepwater centraliser products.

Today, drilling and completion account for around 50% of deepwater field development costs. As oil and gas production moves into deeper waters the technical challenges and risks increase. Centek’s deepwater centralisers are designed for use in wells where as many as nine casing strings can be running through each other so tolerances are extremely tight. The centralisers have to compress fully to travel through the tight casing strings and be able, undamaged, to expand to the designed open hole size to centralise the casing.

Once in position these centralisers provide optimum stand-off and fluid displacement which improves well clean-out. Their low coefficient of friction allows casing to be reciprocated and rotated, improving mud removal and cement displacement and contributing to a good cement bond and long term zonal isolation.

“Centek Group is a leader in deepwater centraliser technology, with the largest centraliser manufacturing capacity in the world,” said Tony Cutmore, managing director Centek Group. “Our 14 years of experience in this field has led to the development of a range of centralisers ideally suited to downhole conditions in deepwater.”

“Specifying Centek’s UROS-CT enabled us to run a series of 17 in. close tolerance liners to a total depth of 16 614 MD RKB ft. without any problems,” commented one operator in Norway’s Ekofisk field.

Centek’s deepwater products include the UROS-CT close tolerance centraliser, the S2 Hinged centraliser for over-sized casing connectors, and the Centek Centraliser Sub designed to be run as an integral part of tight tolerance casing strings. Centek’s Deepwater Stop Collars provide the very high axial strength needed with close tolerance casings. Centek’s Latload simulation software has also proved extremely accurate in predicting standoff and identifying the difficulties of running casing in deepwater wells.
