Centek Group 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.
