Centek: Announces Deepwater Division
Centek Group, the leading centralizer manufacturer, has formed a Deepwater Division to focus the sale and support of its specialist deepwater centralizer products.
Today, drilling and completion account for around 50 percent of deepwater field development costs. As oil and gas production moves into deeper waters the technical challenges and risks increase. Centek’s deepwater centralizers 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 centralizers have to compress fully to travel through the tight casing strings and be able, undamaged, to expand to the designed open hole size to centralize the casing.
Once in position these centralizers 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 centralizer technology, with the largest centralizer 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 centralizers ideally suited to downhole conditions in deepwater.”
“Specifying Centek’s UROS-CT enabled us to run a series of 17” 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 centralizer, the S2 Hinged centralizer for over-sized casing connectors, and the Centek Centralizer 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.
