Casing Centralizers - Bow Spring Centralizer

Centralizers are mechanical devices that prevent casing from contacting the well bore wall. A continuous 360-degree annular space around casing allows cement to completely seal the casing to the borehole wall. Eneroil Centralizers are renowned in the Oil & Gas industry for their standard quality and performances.

Our range of Casing Centralizer includes:

1. Bow Spring Centralizer
2. Single Piece Centralizer
3. Solid Rigid Centralizer
4. Roller Centralizers
5. Thermoplastic Centralizers

Based on the current challenges of well operations, our application engineers have designed cementing equipment that suits larger variety of well applications and this range includes Welded, Non-welded, Rigid, Semi-rigid, Roller centralizers, Bow type centralizer along with our latest masterpiece - Single Piece centralizer & Thermoplastic centralizer.

Eneroil manufactured Casing Centralizers are mechanical devices that prevent casing from contacting the wellbore wall for all kind of well cementing jobs.

Bow Spring Centralizer
Hinged non welded bow spring casing centralizer is a simple, low-cost bow-spring design which can provide complete centralization in vertical or slightly deviated wells as the bow springs are slightly larger than the wellbore.
If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you.

1.The non weld bow centralizers combine the highest restoring force with the lowest starting force.
2.High restoring force combined with low starting force is achieved with all bow heights.
3.The Bows of these Centralizers are heat treated in special furnace which gives it a peculiar â??bow springâ?? action.
4.The Heat Treated bows enables these centralizer to provide best centralization as well as help in faster running of casing.
5.The steel of these bows is a "special" made by combination or different metals to provide one of the best tensile strength as well as the "spring back" bow spring action.
6.The bows are available in a range to accommodate any well profile.
7.In this type of Centralizers the End Collars have hinges which makes it in two halves.
8.This enables them to be assembled at site.
9.The Hinged non welded bow spring centralizers are available in size 4-1/2" to 20".
10.Their installation on the casing pipe is very convenient.It requires only the placement of the two assembled halves on the pipe and inserting the pin in the end collar hinge.
11.The centralizer when unassembled makes a compact package, reducing the shipping cost.
12.Assembly at site is conveniently done.

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.

Description:
Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.

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.
