Eneroil Offers A Quality Range Of Solid Rigid Centralizers That Is Well Suited For Any Well Bore Which Requires To Endure High Pressure Or Temperature. The Extended Range Includes Spiral Blade Solid Centralizer (aluminium/ Zinc/ Steel) , Straight Blade Solid Centralizer(aluminium/ Zinc/ Steel) , Slip On Welded Spiral Spiraslider, Heavy Duty Spiraslider, Rotating Solid Centralizers & Slip-on Stand-off Band(s-40).

Eneroil offshore has developed its Single piece Bow Centralizer (S12) model to perform satisfactorily in Open hole as well as Cased hole. These are high quality product, developed to meet and exceed API10 D specifications for use in highly demanding downhole conditions. Eneroil's Single piece Glider Centralizer (S12) combines the highest restoring force with zero starting force and zero running force. Single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells, reduce the effect of channeling by reducing pipe movement before Cement sets in and improving the cement flow, this results in more uniform cement thickness in the well bore. S12 centralizers are one piece construction in special high strength Steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions.

Eneroil 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. Solid Body Low Torque Roller Centralizers are specifically built to run in an inclined or horizontal section. The rollers outside diameter are kept slightly larger than the centralizer blades outer diameter. When casing equipped with Solid Body Low Torque Roller Centralizer runs into the deviated or horizontal hole, sliding friction between the casing and the borehole is converted into rolling friction. In case of irregular hole diameter, the borehole wall has an impact force on the spiral centralizer during running casings, the use of rollers reduce this impact.

Eneroil Offshore Offers full range of casing centralizer which includes Bow Spring Centralizer(welded / Non-welded), Solid Centralizers, Solid Rigid Centralizers, Positive Centralizers, Gemoco Centralizers, Roller centralizers and Thermoplastic centralizers.All the products are of high quality and comprises of the standard set by API and ISO.
