Centralizer is a mechanical device that keeps
casing from joining the wellbore wall.
With a continuous 360-degree annular space around
casing, it allows the cement to completely seal
the casing to the borehole wall.

 Bow Centralizer is one of the types of
centralizers which is an older and a common
version of low-cost bow-spring centralizer design.
The casing is kept away from making further
contact with the wall. Since, the centralizers
continuous annular clearance around the casing
allows cement to completely seal around the
casing to the borehole wall.

It is a well defined thing to say that each
centralizer types and properties vary from each
other. Also, the exact number of centralizers
required and their placements on the casing are
important to make it work properly.

Centralizer is mechanical device which is secured
around the casing at various locations. Bow
design of centralizer is a slightly larger design
than the wellbore and they can provide complete
centralization in vertical or slightly deviated
wells. Since, they do not support the weight of
the casing, it is very well deviated in wellbores.

Advantages Of Bow Design

• The formed U-profile offers superior standoff
  which is more effective compared to the
  conventional bow-spring centralizers and enables
  efficient liner-hanger and packer setting
• Provides additional flow area to aid in mud
  removal which contributes to a high-quality
  primary cement job
• Special locking tabs connect the bows to the end
  collars to achieve the highest restoring-force-to-
  drag ratio when run in hole in cased-hole
  applications
• Outstanding lateral resistance, flexible,
  nonweld design which is available on both slip-on
  and latch-on versions

Since, earlier the entirely development of
machines were low and the awareness was low as
well. Now, on the other hand, because of digital
media, the competition have increased and people
have started to explore various features of
machines. 
Bow Centralizer being used for casing the center
of a wellbore or during a cement job, is a metal
strip shaped like a hunting bow and attached to a
tool or to the outside of casing.

This Bow design takes an efficient step towards
quality cementing can lead to severe cementing
problems including lack of zonal isolation and
improper casing support for the lack of proper
centralization. Bow Design allows the cement to
be evenly distributed around the casing string.
This is easy to assemble, time saver and availed
with a strong grip.

Bow Centralizer increases fluid turbulence at the
tool and helps to remove filter cake from the
wellbore. This can be run through hole
restrictions in the wellbore or through smaller
casing strings that are cemented in the well.
The better way to perform is a standoff analysis
for each casing before a cementing job. Also, the
exact number of centralizers required and their
placements on the casing are important to make it
work properly.
