Float EquipmentGeneral
STM has been ma nufac turing high qu ality floa t equipm ent since 1987. In 1999 STM
successfully commissioned a state of the
art computer controlled API test loop facility
for testing float equipment. The STM test
loop is the only one of it's type in Asia and
features a high volume facility for simulating
realistic down hole conditions to monitor
erosion and other effects to float equipment
under extended circulating conditions. The
high volum e com ponent of the loop utilizes
drilling fluids to API specifications complete
with abrasive solids and is capable of
pumping volumes well in excess of 25
barrels per minute.
The STM test loop facility also incorporates
a h igh tempera ture h igh pressure
component capable of testing at sustained
temperatures in excess of 400 degrees
Fahrenheit (204 C) and pressure in excess
of 5,000 PSI for testing products in
accordance w ith API RP-10F (all categories).
Whilst the STM test loop facility was commissioned to support and enhance the STM
range of float equipment the facility can be made available for third part product testingand verification.
Where applicable STM float equipment is manufactured by in house CNC machinery to
ensure conformity and quality. Once machined, components are individually inspectedand certified by our independent quality team. Standard STM float equipment meets or
exceeds API requirements. STM maintains a large inventory of raw material and generally
is able to manu facture components with s pec ial ch emical o r physical properties expediently.R a w ma t e r i a l s wh e r e a p p l i c a b l e a r e A P I c e r t i f i e d a n d f u l l y t r a c e a b l e .

To meet modern requirements for float shoes and collars to provide a positive seal
in highly deviated, horizontal, high temperature and hostile environments STM has
developed this new range of premium products capable of meeting and exceedingthese deman ds.
STM plunge r valve s meet and exceed API RPF 10F categories 3C (5,000 psi and 40 0degrees F).
STM Plunger Type float equipme nt is avai lab le in sizes ra nging from 2 7/8" through
to 30" and is fully PDC drillable, even the valve spring is constructed from PDC
drillable materials. The STM Plunger type float collar can be supplied with optionalnon rotating feature for faster drill out.
STM float shoes and f loat col lars both Plunger and Ball type uti l ize Compressa-Strength technology. Compressa-Strength util izes the natural compressive strength
chara cteristics of cement by greatly reducing shear stress points that are incorporated
in the design of wicker style products. As an integral part of the STM quality system,
float equipment insert cement samp les a re tested by a qualified independent laboratory
to ensure product quality and consistency.
Ball Valve
Type Float Shoes and CollarsThe Ball type float shoe and float collar range is for the customers who prefer no
me chanical parts (springs) and encompasse s the same Compressa-S trength shell
design as the plunger type for maximum integrity. Ball type valve products are
available in sizes from 4 1/2" through to 30" and are fully PDC drillable. The STM
Ball type float colla r is also available w ith an op tional non rotating feature for faster
drill out.

Cementing Plugs(Standard and Non-Rotating)
STM offers a complete range of cementing plugs in sizes ranging from 2 7/8" throughto 20". Our premium Casing Cementing Plugs are PDC drillable with heat resistance
of 300 degrees F and are color coded with bright orange Bottom Plugs and black Top
Plugs for easy visual identif ication. STM Casing Cementing Plugs are extremely
durable with high abrasion resistance and able to withstand pressure differential of
standard float equipment. STM can also provide high temperature Cementing Plugs.We also manufacture custom plugs to customer requirements.
STM Non-Rotating Cement Plugs are retrofitted with durable, high temperature plastic
inserts to prevent plugs from spinning whilst drilling out. A unique feature of the
STM non-rotating plugs is that the drive faces are radially mis-aligned from locating
faces so that the two components are axially locked. This prevents the plug from
bouncing and sp inning wh ilst drill ing out. The design of the locating faces also
ensures ax ial positioning regardless of borehole angle .

DescriptionSTM circulating differential
f i l l shoes and co l la rs ,
through the action of a
d i f f e r e n t i a l p r e s s u r e -
actuated valve, al low the
casing to automatically fil l
with well fluids as they are
run in the hole. The fluid
level in the casing will be
regulated to not exceed90% of the level in the
an nu lus if one shoe or collar
is used, and the fluid level
will not exceed 81% if both
are used. Valve components
are made o f an eas i ly
dr i l lable a luminium al loy.
Features
• Circulating differential fill equipment automatically fills the casing string as it is
run, eliminating the time required for surface filling and thereby reducing the possibilityof sticking the casin g.
• Pressure surges during running-in are significantly reduced since fluids are allowed
to enter the casing. By reducing pressure surges, formation damage and loss ofdrilling fluids to the formation are minimized.
• Circulation can be reestablished at any time. The automatic differential fill valvewill resume functioning when circulation is stopped and the casing is again run tothe point where the casing fluid level is less than 90% of the annulus level.
• Dropping a trip ball to seat in the circulating differential fill equipment and applying
pressure to the string will convert it to conventional float equipment. When shoe and
collar are run together, one tripping ball will convert both pieces of equipment.
Performance is equivalent to f loat equipment performance shown in Table 1.

Operation
Running-in
As the string is run into the hole, fluid enters the circulating differential fill equipment
and flows up through the flapper releasing the sleeve, which is locked in the open
position, and then flows through the flapper differential pressure valve into thecasing.
The differential pressure valve assembly consists of a differential piston and a valve
seat. The differential piston is designed so that the cross-sectional area at the bottom
of the piston is 90% of the cross-sectional area of the top. When the fluid pressure
on the top side of the differential piston begins to exceed 90% of the fluid pressureon the bottom, it will move downward and seal on the valve seat, preventing further
flow into the casing. As the casing continues to be lowered, the fluid pressure on
the bottom of the differential piston increases until it again opens, permitting fluid
to enter the casing. This cycle is continuously repeated as the string is run into thehole.
If both a circulating differential f i l l shoe and a collar are run together, the tandem
effects of both pieces of equipment will result in a casing fluid level of 81% of theannulus level.
Circulation
Circulation can be reestablished at any time by fi l l ing the casing and pumping fluids.
When circulation is stopped, the differential pressure valve assembly will resume
functioning when the casing is run to the depth where the casing fluid level is lessthan 90% of the annulus fluid level.
Tripping
To convert differential f i l l equipment to float equipment, a tripping ball is dropped
down the casing. A pressure of 500 to 800 psi will shear the screw holding the flapper
releasing sleeve in place, allowing it to move down and release the flapper valve.When the flapper releasing sleeve seats on the valve bottom, the dogs are forced
into a recess, allowing the tripping ball to pass through. The lower flapper and flapper
releasing sleeve are independent of the differential piston which ensures proper fillingand seating as demanded.
When two pieces of differential f i l l equipment are run together, the same ball will
trip both.

This equipment facilitates "nippling up,' reduces cement contamination at the critical
shoe area, minimizes the problem of excess cement when trying to circulate cement
to the surface and provides for more efficient use of spacers and washes. STM stab-
in equipment is specifically designed for this application. When the stab-in shoe is
run, no other float equipment is necessary. The stab-in collar is designed to be run
in conjunction with a guide shoe and is normally placed one joint above the guideshoe.
The design of the shoe and collar is similar. Each is equipped with a spring-loa ded,
flapper float valve held open by an orifice. This orifice allows the casing to fill
automatically while regulating the rate of fill to prevent overflow. Above the orificeis a seat for a latch-down plug and a retaining latch for the stab-in, latch-in device.
8/11/2019 Casinghardware Saga Trade Product r
http://slidepdf.com/reader/full/casinghardware-saga-trade-product-r 21/37
Operation
The casing is run into the well. The stab-in stinger and centralizer (optional) aremade up on the drill pipe and run into the hole.
The beveled top of the stab-in shoe or collar, and optional centralizer above the stab-
in unit, help the stinger seat in the collar or shoe, even in deviated holes. When the
stinger is seated, circulation may be established through the dril l pipe and up the
annular space between the casing and the hole. A weighted ball may then be dropped
down the dril l pipe and either pumped down or allowed to gravitate to the seat. A
pressure of 800 psi will pump the orif ice out and release the flapper valve which
then becomes an efficient float valve. The proper amount of cement is then mixed
and pumped down the dril l pipe. A flexible latch-in plug, supplied with the tool, isused to follow the cement slurry. This plug is pumped to a shutoff. The stinger may
then be released from the stab-in collar by pulling slightly over dril l-pipe weight andthen rotating six turns to the right.
The stinger may be run with or without the retaining slip. If the retaining slip is not
used, the weight of the drill pipe is used to hold the stinger in place while cementing.In this case, no rotation is necessary to release the stinger.
Stab-in shoes or collars may be run with or without the automatic-fill orifice.

http://slidepdf.com/reader/full/casinghardware-saga-trade-product-r 22/37
The same principles are util ized as those of the stab-in, latch-in shoe with these
exceptions:(1) the stinger sub will not latch into the shoe, therefore drill-pipe weight must be
used to hold the stinger in place while cementing; (2) the stab-in, setdown does not
have a latch-in wiper plug to follow the cement as the stab-in, latch-in shoe; and
(3) the stab-in setdown has a standa rd ball or plunger type float valve which do es not fill whilerunning casing.
Operation
The shoe is made up on the casing and run to setting depth. The stinger sub and
optional centralizer are made up on the drill pipe and run into the well. The beveled
top (receptacle) of the float shoe, and the centralizer on the stinger sub, help thestinger seat in the shoe. When the stinger is seated, circulation may be established
through the dril l pipe. Dril l-pipe weight must be used to hold the stinger in place.The required amount of cement is then mixed, pumped and displaced to the shoe.
The stinger sub is then removed from the shoe by upward movement of the dril l
pipe. Circulation may be established through the dril l pipe and inside the casing.
Stage Cementing Collars
Two- Stage Cementing CollarThree Stage Cementing
Description
STM stage cementing collars are used for cementing a
casing string in two or three separate stages: (1) to
reduce the circulating pressure and hydrostatic head
encountered in cementing and, thus, prevent the
breakdown of weak formations; (2) to reduce cement
contamination effects; and (3) to reduce the quantityof cement required when cemented intervals are widely
separated. Stage cementing can also be used to place
a retarded slurry at the bottom of a high-temperature
well rather than circulat ing the slurry up to lower
temperature zones where it might not set in a reasonable
time.
8/11/2019 Casinghardware Saga Trade Product r
http://slidepdf.com/reader/full/casinghardware-saga-trade-product-r 23/37
The "regular method" of two-stage and also three-stage cementing consists of placing
the cement in separate operations. Two-stage cementing can be accomplished bythe "continuous method" in which both stages of cement, separated by a displacementfluid, are p laced withou t interruption.
Features
• The trouble-free design of the STM stage collar has only two moving parts.
• The case, top and bottom connections, and sleeves are constructed of 4140 grade
steel which is heat-treated to S95 physical propert ies (H2S-resistant) .
• Operation is achieved by the application of pressure to the casing fluid after the
plugs supplied with the stage collar have seated.
• The sealing 0-rings do not pass over any ports, sheared pins or sharp edges that
could be dam aging to their sealin g effectiveness.• A la tch r ing pos i t ive ly locks both s leeves in the c losed posi t ion.
• The latch ring and groove are protected from foreign matter by seals on each side.
• Opening and closing sleeves are locked to prevent rotation during drillout.
• Opening and closing sleeves plug seats are made of easily drillable alumunium
alloy.
• The STM two-stage collar and accompanying plugs are colour-coded black while
the three-stage collar and accompanying plugs are colour-coded orange to help
assure proper order of installation and operation.
OperationWhile running the casing string in the hole and during the cementing of the first
stage, the stage collar remains in the closed position. The first-stage flexible plug
passes through the stage collar without actuating the sleeves. To open the stage
collar cementing ports, a gravity opening plug is dropped and allowed to fall to the
opening sleeve seat. Pressure is then built up in the casing to shear the openingsleeve shear screws and to move the sleeve down to expose the cementing ports.
The second-stage cement is then pumped and immediately followed with the closing
plug. The closing plug is pumped to the closing sleeve seat and pressure is applied
to shear the closing sleeve shear pins and force the sleeve down to close the cementingports. The closing sleeve is permanently latched in the closed posit ion.

General
Recommended practices for primary cementing should be followed. These include
conditioning the mud, centralizing casing, and using spacers and/or chemical washes
ahead of the cement. Use of cable wall wipers and pipe movement, when cementing
the critical first stage, will help to achieve good cement bonding. Centralizers shouldbe used immediately above and below the stage collar. A cementing basket shouldalso be used below the stage collar.
STM stage cementing collars are inspected and packaged with the proper wiper plug,
gravity opening plug, closing plug and rubber seal-off plate. STM can recommend
and supply all casing hardware and services needed for stage cementing your well.

passes through the two-stage collar without affecting it in any way. The first-stage
plug is displaced to a shutoff on the float equipment immediately below the stage,
as shown in Figure 1B, completing the first stage. The stage collar ports are then
opened by dropping the gravity opening plug and allowing it to gravitate to the
opening sleeve seat in the stage collar. Application of 1,200 to 1,400 psi above
circulation pressure will shift the sleeve downward, opening the cementing ports.
T he s ec ond s tage of ceme nt is pumped followe d imme dia tely by the clos ing plug,

T he continuous method require s that a bypa s s insert be used for s ea ting the firs t-
stage plug. A pump-down opening plug must be used in place of the gravity opening
plug. All other equipment is the same as used in regular two-stage cementing. In
Figure 2A, the first stage of cement and the first-stage plug are being pumped. The
displacement fluid, calculated to be slightly more than the casing volume between
the bypass insert and stage collar, is followed by the opening plug. The flexible first-
stage plug and bypass insert allow for some overdisplacement of the first stage topositively seat the opening plug.
A spacer and the second stage of cement immediately follow the opening plug. When
the plug seats in the stage collar, pressure is applied to open the cementing portsas shown in Figure 2B. The second stage of cement is followed by the closing plugand displacement fluid (Figure 2C).
In Figure 2D, the closing plug is shown after it has seated in the stage collar and
pressure has been applied to close the stage collar cementing ports.

Three-Stage Cementing
The three-stage collar is identical to the two-stage collar except it has plug seatsw i th la rger bores to a l low f ree pass ag e o f the tw o- s ta ge p lugs .
Procedures for three-stage cementing are similar to those for a two-stage cementing
job. The first and second stages can be ce mented using ei ther the re gula r or
continuous method. The third stage is cemented using the regular method. The
closing plug for the two-stage collar is special. The special two-stage closing plug
must be ordered separately for three-stage cementing.
Figure 3A shows the first stage completed and the second stage of cement being
pumped through the two-stage collar. The second stage of cement is followed by thespecial two-stage closing plug. When the plug seats in the stage collar, application
of pressure will shift and latch the port-closing sleeve.
The third stage is completed (Figure 3B) by dropping the three-stage gravity opening
plug and applying pressure to the open cementing ports. The cement is then pumped
followed by the three-stage closing plug. Pressure is increased to close the stage
collar and complete the job. Note that the three-stage collar and plugs are color-
coded orange, while the two stage collar and plugs are color-coded black.
