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.

A ball guide insert is available and should be installed on top of each piece of

differential fill equipment, for casing sizes 7 in. through 13 3/8 in. in holes deviated

30° or more.

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.

Page 21: Casinghardware Saga Trade Product r

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.

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.

Page 23: Casinghardware Saga Trade Product r

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.

 T he s tring is made up as s hown in figure 1A, run in the hole , and the firs t-s tage

cement pumped. The first-stage cement is followed by the first-stage plug which

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,

as shown in Figure 1C. Figure 1D shows the closing plug displaced to shut off on the

closing sleeve seat in the stage collar. Pressure has been applied to shift the closingsleeve and shut the cementing ports. A minimum pressure of 1,500 psi above that

required to close the stage collar. The closing sleeve is permanently latched in the

closed position, completing the second stage.

  C e m e n t inC o n ti n u o u s T w o -S ta g e g

 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.
