CEMENT RETAINERS
The ACT Model BKR Premium Cement Retainer (W/L) is a wireline set, high-pressure retainer constructed of drillable cast-iron that uses Bolt, Elder, or Baker K-1 type setting sleeves and tension mandrels. Cement retrainers, It can be set on any Baker-type wireline pressure setting tool or pipe/coil tubing with an ACT Hydraulic Setting Tool. When set, opposing slips are located above and below the rubber packing elements.
This retainer is ideal for where squeeze cementing operations are being performed. Optional packing systems of Viton or Aflas are available on special orders. Special application tools can be custom-designed to fit your specific needs. After the ACT BKR Cement Retainer is set on wireline a BKR Seal Unit is required to perform the squeeze job. These seal units are available in two types, a locator seal unit or a snap latch seal unit. The sealing unit is installed on the bottom of the work string to control the two-way valve in the set retainer. Cement retrainers
MODEL BKR PREMIUM CEMENT RETAINER – WIRELINE SET / DRILLABLE
The ACT Model BKR Premium Cement
Retainer (W/L) is a wireline set,
high pressure retainer constructed
of drillable cast-iron that uses
Bolt, Elder or Baker K-1 type
setting sleeves and tension
mandrels. It can be set on any Baker
type wireline pressure setting tool
or pipe/coil tubing with an ACT
Hydraulic Setting Tool. When set,
opposing slips are located above and
below the rubber packing elements.
The packing elements are contained
by rocker action back-up rings that
eliminate extrusion of the elements
at high temperatures and pressures.
A one way ratchet lock ring retains
the setting force applied to the
opposing slips and rubber to
maintain a pressure tight seal.
One-piece slips keep the retainer
securely set in premium grade
casings including P-110.The slip
wickers are sharp and hardened to
the wicker depth only allowing the
slip to grip the casing wall while
maintaining a soft cast-iron inside
for easier drilling.
It features a pressure balanced two
way valve located in the bottom
shoe. The operator controls the two
way valve from the surface to hold
the final squeeze pressure under the
retainer or test tubing or keep
hydrostatic pressure off the
squeeze. Straight pick up closes the
valve and set down weight opens the
valve. This retainer is ideal for
where squeeze cementing operations
are being performed. Optional
packing systems of Viton or Aflas
are available on special order.
Special application tools can be
custom designed to fit your specific
needs.
After the ACT BKR Cement Retainer is
set on wireline a BKR Seal Unit is
required to perform the squeeze job.
These seal units are available in
two types, a locator seal unit or a
snap latch seal unit. The seal unit
is installed on the bottom of the
workstring to control the two way
valve in the set retainer.

SUGGESTED ROTARY DRILLING TECHNIQUES DRILLABLE CEMENT RETAINERS – BRIDGE PLUGS
When drilling a cast iron cement
retainer or bridge plug the same
considerations should be used as
when drilling a medium hard
formation. Drilling with a medium
tooth medium hard formation rock bit
is usually the best combination.
Spudding the work string and
variations in rotary speed and set
down weight should be used to aid in
breaking up large metal parts and
preventing bit tracking. One or more
junk baskets should be used above
the bit when normal circulation is
employed. Bit – Medium tooth medium
hard formation rock bit. Rotary
Speed – 75 to 120 RPM is suggested.
Weight on bit – Apply 5,000-7,000
lbs. until top end of bridge plug or
cement retainer body is drilled
away, 4-1/2 thru 7 (3-5 inches)
7-5/8 and larger (5-9 inches). An
additional 3,000 lbs. of weight can
now be applied per inch of bit
diameter to drill the remainder of
the cast iron product. Example:
4-1/2 bit will use 9,000-13,500 lbs.
of weight.
Drill Collars – Should be used for
weight on bit and bit stabilization.
Example: 4-1/2 thru 5-1/2 (8-min.) 7
and larger (12 min.). Junk Baskets –
One or more junk baskets should be
used above the bit. Annular Velocity
– 120 feet per minute is suggested.
