Saigao developed the "Solid Body Low Drag Roller Centralizer" as axial drag friction reduction tool. The contact area of the rollers with the casing or borehole wall functions well in under pressured conditions, where the risk of differential sticking is high.
The "Low Drag" centralizer with steel rollers helps to avoid ploughing through wellbore material that has settled, alleviating major drag problems in deviated and horizontal wells.
Casing, Liner and screens are being run into horizontal and extended-reach wells
Under pressured formations may cause differential sticking
Non weld bow centralizers are available in the sizes 4 1/2" to 13 3/8"
Any special sizes or combination can be made available on request
