INTERNATIONAL

TOOL CO.

HOUSTON,

TEXAS

A BRIEF

HISTORY

Founded

in

1958,

A-Z

International

began

business with

a

charter to supply superior products and s ervices to the oi l and

gas wel l

drilling

industry on a world-wide basis. The initial prod-

ucts were downhole mil l ing tools which were marketed both

domestically and internationally. The bulk of A-Z's initial sales

were

in Venezuela, more specif ically, sales and service opera-

t ions were centered in the Venezuelan states of Anzoategui and

Zulia

which are the equivalent of Texas and Louisiana in the

domestic market. A-Z International Tool Company draws its

name from

th e first

letters

o f

these states.

In

1960, underreamers were

added

to the product l ine and

A-Z's domestic service operations were expanded

to

meet

growing industry needs. Casing cutters were introduced

in

1964

which led A-Z to develop prop r ietary plug and abandon

methods for offshore wel ls and a variety of new tool system s fo r

the offshore dril l ing industry. Focusing engineering and oper-

ational talent on marine dril l ing needs eventually led to the

patented "One-Trip Cut and Recovery System" for recovering

subsea wel lheads from the ocean

floor.

A-Z's first international s ervice center opened

its

doors

in

1965

in

Venezue la. Since that time, international service cen ters have

been founded

in

Scotland, Singapore, Brunei, Indonesia, C hina,

Egypt, Oman, Norway,

and Angola. 'Dom estical ly the

company

operates from seve ral locat ions on the G ulf and P acif ic coasts.

En joy ing a s teady g rowth a nd pro f i t ab i l i t y , t he c om pan y

established its own product manufacturing operation in 1963 at

3317 W est 11th Street in Ho uston,

Texas,

and has been head-

quartered

at

that location since.

To

meet

market

demands,

A-Z's

Service Tool man ufacturing capabi l i ty and capacity have been

increasing steadi ly s ince 1963 and curre nt ly are house d in a

30,000 square foot

facil i ty

in Houston.

Dri lled-in permane nt anchor pi les w ere introduced by A-Z to

th e

f loating dri l ling industry in 1958 and have been su cces sful ly

appl ied in most act ive offshore basins throughout the w orld. A-Z

pioneered dril led-in pil ing systems for both the offshore dril l ing

industry

and the

offshore construct ion industry

and is the

recog-

nized "expert" in this field.

In

1975, A-Z was acquired by the M asco Corporation o f

Taylor,

M ic h iga n . Masco 's energy re la ted group o f comp anies and

divisions has since grown to include such o rganizations as G rant

O il

Tools, Dri l lex Sys tems, Inc./Re di-Dri l l , Mountain States

O il

Tools,

MW L-Lindsey Com pletion S ystem s, Foster Oilfield Eq uip-

ment Co., Arrow O il Tool, W alker-McDona ld, an d Arrow Spe cialty

Products. Being a mem ber of a group of energy related product

a n d se r v i ce compan i es h a s s t r eng t hened a n d b ro a d e n e d

A-Z's cap ability to deliver supe rior, innovative products, systems,

and s ervices to i ts customers.

In

1981 and 1982, A-Z International continued to demo nstrate

its engineering leadership and product innovations. A-Z intro-

duced

a

com bination packer

an d

whipstock

designed to

provide

a

means

of

sidetracking

in a

cased hole. Named

the Pack-Stodk,

this unique tool saves time

and

money

by

reducing

the

number

of trips needed to cut a casing windo w. Later in 1982, A-Z added

the A-Z Hole Opener to its l ine of drilling tools. Made ent irely of

forged components, the A-Z line o f Hole Open ers enables A-Z to

offer

its

cus tomers

a

com plete l ine

o f

hole opening

and

under-

reaming services.

With n ew tools such a s the Pa ck-Stock, Hole Opener, and the

Dyna-Cut,

A-Z's new explosive w el lhead

sever ing

system , A-Z

Internat ional h as cont inued ex panding i ts capabi li ty to meet

industry needs.

Six

reasons why we are No. 1 on f loaters, jackups and

semi-

submersibles:

One Str ing of Tools • One Package • One Company • One

Invoice • One Operator • One Respo nsibil ity and Total Service.

W e a re

offer ing total service

to

m ake o ffshore dril ling faster,

more eff icient and more eco nom ical. W ith only one str ing of A-Z

Tools,

you can now do all of the cutting, mill ing, pull ing, fishing

and patching jobs that wi l l ever be necessary.

And A -Z is the

ONLY company that

Systems

And al l of our tools are engineered to withstand the severe

service encountered in underwater operat ions —

• Beefed-up ma rine cutters that can cut 20", 30" and even 60"

pipe

with varying wal l thicknes s.

• Marine spears that can be used with r ight-hand rotat ion to

release

underwater

connectors.

• Marine swivels that can be used for abandonm ent, patching,

fishing

a nd

cutting,

or for

dril l ing, setting

and

cementing con-

ductor

pipe.

• Special marine casing patch tools with ext ra long extension to

accommodate

any

amount

of

stretch.

• Single and dual rock-type u nderream ers that can be used for

drilling large holes through smal l blowout preventers, or for

dril l ing in, setting and cementing anchor pil ing or conductor

pipe w ith one tr ip in the hole.

Al l of these add u p to a com pact package that wi l l get the job

done faster an d more eff icient ly fo r less money. By doing so

many jobs with so few tools, savings are mult ipl ied:

LESS C PIT L

INVESTMENT

LESS INVENTORY

LESS

LESS STO R GE SP CE

By get ting the complete package f rom one company, only

one service engineer is needed. A trained special ist who kn ows

every

part

of

and can

operate

all of the

tools

is

certainly the best approach to cutt ing, f ishing and patching.

DYNA-CUT EXPLOSIVE

MULTI-STRING SEVERING SYSTEM

OPERATION

Th e

"Dyna-Cut" W ellhead Severing System is shipped to the

rig in the o ffsho re box with sufficient materials to assemble two (2)

charges. Th e f ir ing con trol box and the f ir ing module a re hand-

carr ied

by the A-Z

service operator

to the rig. The

service oper-

rator assembles

the

charge

and

mixes

the chemicals — the

chemicals

are not

explosive until they

are

properly mixed

by

percen-

tage

o f

vo lume.

The

charge

can be

lowered into

the

wellhead

on

a

sandline using

guide

wires

or on a

running tool using drill

pipe/stinger.

Th e

method illustrated

is the sandline

method.

USE

The "Dyna-Cut" Wellhead Severing System

is

capable

of

severing up to f ive (5 ) cemented str ings o f casing (7" - 9-5/8" -

13-3/8" - 20" - 30") at once w ith no danger to the drilling rig, rig

personnel orthe

envi ronme nt . ''

D yna-Cut '' can be combined with

the conventional A-Z marine casing cutting tool package for a Dual

Plug & Abandonm ent System, which allows the small casing sizes

to be cut and pulled mechanically and he remaining casing strings

to be severed explosively.

DV NT GES

• The "Dyna-C ut" charge

filler

is stored on the rig in separate

containers as af lamm able l iquid (Nitrome thane) and as acor ro-

sive

acid (Diethylenetriamine). Both

are

biodegradeable

and

are

not

combined until

A-Z

technicians prepare

the

charge

container just before lowering it into the well bore.

• The

exploding

bridge wi re (EBW) detonators conta in no

primary explosive

and can

only

be

actuated

by the A-Z

f ir ing

module, which

is

hand -carried

to the rig by an A-Z

technician.

• There is no possibi l i ty of accidental detonation by o ther

sources such

as

radio signals, allowing

the rig to

maintain

full

communications throughout the operation.

• The

"Dyna-C ut" system

is

safe

and the

method

of

storing,

handling

and

detonating

the

explosive charges makes

the

system fool-proof.

• This system can also be used to jar a subsea wellhead loose

from

the

ocean f loor after

a ll

casing

h as

been

cu t

mechanically.

Occasionally f r iction or excess cement wi l l prevent the well-

head from being retr ieved. T he "Dyna-Cut" charge wi l l f ree

the wellhead for retr ieval.

USE

The

A-Z

Marine Casing Cutter

is

builtto withstand extremesh ock

encountered in cutting multiple

strings of

uncentralized conductor

pipe. D ueto the unique co nstruct ion of thistool , the rugged cutter

arms expand outwa rd up to 5 times the diameter of the tool body

and achieve m aximum stabil ity under al l type s of adverse cutt ing

conditions, including hard spo ts, eccentricity, interrupted cuts, eta.

For

example , the 13

3

/s" casing cut ter measures only 11%"

diameter and cuts all ranges and weights of pipe through

60".

ADVANTAGES

• Cuts mult iple strings smoothly, even when each str ing is

not concentr ic.

,

•

Affords maximum expansion

of

blades

up to 5

time s

body

diameter.

• Rugged

3-blade

const ruct ion provides fast cut at high

speeds.

•

Cutter arms

can be

easi ly retracted

by

simply picking

up on

drilling string.

•

Cutter arms

can be

changed

on rig floor.

OPERATION

The A-Z M arine Casing C utter is simple to operate. Th e tool is

run to the de sired depth and slow rotat ion is started. The pumps

are

turned

on

and,

as the pressure in the

tool

increases,

a

piston

is actuated, m oving the cutter arm into cutting po sition. Rotary speed

is

accelerated and pump pressure is gradual ly increased unt il the

cut ter arms have expanded to thei r maximum posi t ion.

Af ter

finishing

the

cut,

the

tool

is

retracted

by

simply shutting off

the

pumps

and picking up.

USE

The A-Z Marine Spear is used to engage a f ish internal ly in

order that it may be pulled or jarred from the hole. It is also used

to reconnect casing which is

stuck

off bottom.(See page

10.)

ADVANTAGES

The A-Z

Marine Spear

is

especial ly designed

fo r

Marine

Operat ions.

The A-Z

Marine Spear—

—Will pass through restr ict ions in wel l heads and blowout

preventers and

catch ful l gage below.

—Easily converts from bumper to str inger type simply by

removing stop r ing.

Has only one w orking part in i ts rugged three-p iece con struc-

tion.

No

springs,

no

cages,

no

wipers.

,

OPERATION

The A-Z Sp ear is easy to ope rate. The spear is made up on

the bottom of the str ing and run into the hole. Thereupon the

string

is

careful ly lowered unt i l

th e

nose piece

of the

spear

enters the f ish. When the sl ips enter the f ish, a sharp decrease

of s tr ing we ight wi l l be noted, indicat ing that the f ish has been

entered.

When running the spear as a str inger type i t should be

lowered seve ral feet into the f ish so that a f i rm grip on the pipe

will

be maintained and also to reduce the tendency to spl i t the

f ish

if

severe

pulling or

jarring

is

encountered. Whe n running

the

spear as a bum per type, s uff icient weight should be appl ied to

the string to insure that the bum per ring is resting solidly on top

of

th e

f ish.

Pick

up on the str ing. This act ion causes the sl ip to spread

outward on the mandrel , bit ing into and s ecurely engaging the

f ish. The

fish

m ay

then

be

pul led from

th e

hole

or may be

a r red

repeatedly if necessary.

If, for any reason, th e f ish cannot be pulled or jar red f rom the

hole, drop the str ing sharply on the spear. Bumping down on

th e

spear wi l l break the fr ict ion between the mandrel and the

slips, al lowing the mandrel to move downward with relat ion

to

the slips.

With the spear in this position, rotate the string one or two

turns to the r ight and pick up. Right hand rotat ion causes the

sl ips to remain in the released posit ion, in which posit ion the

spear may be withdrawn from the

f ish.

The spear may be

re-engaged and released as many t imes as desired without

coming out of the hole.

RSP-30

MARINE SPEAR

The A-Z R SP 30

Ma rine

Spear has a rugged heavy duty body.

It

is a

bumper type spea r designed

fo r

engagement

and

pulling

of 30" casing. The slips arecarburized to ensu re positive engage-

ment of the fish. This tool has an integral packoff

element

which

seals against the casing I .D. whe n the slips are set. By sealing o ff

on the casing I .D., hydraul ic pressure may be appl ied below the

tool which adds

lifting forc e to the fishing

string.

It operates the

same

as standard A-Z Marine Spears. Th e spear may be re-engaged an d

released as many t imes as desired without coming out of the hole.

Th e RSP30

may be converted to

a

RSP 36 fo r work inSS" casing

by simply

changing the

slips

and

adding

a bumper

ring adaptor.

This

conversion may be made without disassembly o f the tool.

USE

The A-Z Marine Swivel is used on f loaters to suspend the A-Z

Marine Casing Cutter in the hole and maintain it at the same

level during the cutting operation.

It

is also used on jackup s wh en running the A-Z Single Trip Cu t

and Rec overy System. The swivel can be seated on the ca sing

hanger or wellhead. With the use of the compe nsator the wav e

action imposed on the vessel will not

affect

the vertical position

of

the

cutter.

The AZ M arine Swivel comes in two de signs, the MSA-10 and

the heavy duty MSB-10.

CONSTRUCTION

THe MSB-10 is stronger than the MSA-10. In both tension and

torsion

it is

approximately twice

a s

strong.

For

this reason

we

strongly recommend that the MSB-10 be used in most deep

water

appl ications especial ly w here hea vy seas, strong ocean

currents,

and

other adverse factors exist.

As the

w ater depth

increases, the eccentric motion of the dril l string increases and

this, coupled with the fact that the vessel may at t imes be

misaligned with the center of the

hole, imposes

severe

bending

and shock load on the swivel . The MSB-10 swivel is bui l t to

withstand these loads.

ADVANTAGES

• Insures smooth cut even in the roughest seas.

• By

accurately spacing

out

between

the

swivel

and the

cutting

t ip of the arm, a cut can be made at a precise level within

fractions

of an

inch.

16

• Sealed, o i l-bath con st ruct ion insures long, trouble f ree

operat ion and low maintenance costs.

• P rec is ion ro l l e r - t ype bear ings take thrus t l oads up to

500,000 Ibs.

• By

simply changing adap ters

on the rig

f rom

5

up .

OPERATION

The A-Z Marine Casing Cutter is run on the bottom of the

str ing. The exa ct point of cutt ing can be determ ined by mea sur-

ing

from

the

swivel

to the

cutting

tip of the

arm.

The proper size

of adapters for the casing hanger are then instal led on the

swivel.

Th e

swivel

is

slowly lowered into

the

hole un t il

it

seats

on

the

casing hanger

or

we l l head

and

sufficient weight

is set on the

swivel

to

allow

the

compensator

to

separate.

Slow rotat ion of the pipe is begun, usual ly from 10 to 20 rpm,

and the pumps are turned on. The housing of the swivel , seated

in the wel lhead, remains stat ionary whi le the ma ndrel rotates

with the string and turns the cu tter below.

ADAPTERS

The MSB-10 Sw ivel can be used w ith adapters for all sizes of

pipe from 13

3

/s" to 30". In si tuat ions where smal ler casing is

encountered

(5

1

/2",

7", 9%") the adapter is

replaced

with an

adapter s leeve and sub. In the MSA-10 swivel the adapter

sleeves and subs are only required when cutt ing

A-Z CASING PATCH

USE

The A-Z Casing Patch Tool is used to connect and seal 2 strings of casing of the same

diameter. Over a period of time, due to adverse well conditions, casing deteriorates and

becomes

damaged beyond use.

In

many

instances, it is possible to

remove

the

upper

po rtion

of the damaged casing and, by means o f the patch tool, conne ct a new section of casing to the

bottom portion. In other instances, casing so me times sticks when going in the hole and when

this condition occurs on a

floater,

then it becomes necessary to remove the upper portion of

the stuck casing an d re-connect below the ocean floor suspension system b y means of a

casing patch in order to continue normal operations.

ADVANTAGES

The A-Z Casing Patch is designed for use in land operations and also for use on jackup s in

offshore

operations. A n alternate design with extension i s also a vailable for use on f loaters.

The A-Z Casing Patch utilizes high grade alloy. Three packoffs assure a tight seal under

adverse well conditions.

OPERATION

The A-Z Casing Patch is simple to operate and maintain. The Casing Patch

Tool

is made

upon

the bottom of the casing string and run into the hole un til the bottom of the casing patch is a few

feet

above the casing to be patched. The pum ps are started and the hole is circulated clean.

Slow

rotation

of the

casing string

is

then begun

and the

casing patch

is

slowly lowered until

the

bowl

of the

patch engages

th e

low er string

and

bumps

up

against

the

stop

in the

upper part

of

the

bowl. When the casing patch shoulders up, a definite indication can be noted on the

weight

indicator.

A

strain

is

then taken

on the

casing string.

The

casing

is

then pressure-tested

after which

normal operations are resumed.

For

detailed operational procedure used in setting the casing patch on floaters , please

DRESSING TOOL

AND

PILOT

MILL

USE

The A-Z

Type

R Dressing Tool and Pilot Mill has two uses:

1. It is used to smooth and

bevel

the top of a cut fish prior to

setting a casing patch.

2.

It is used to mill stuck wash pipe, l iners, casing, and screens.

DV NT GES

Fo r dressing, the bottom of the cutting element is dressed at

45° The

resulting angle

cut on the

casing prevents damage

to

the packoff

elements in the

casing patch.

The nose piece is provided with stabilizer blades to insure

proper

centralization

of the

cutting element.

The

O.D.

of

these

blades

is

generally

V a

less than

the I.D. of the

casing

to be

milled.

The A-Z Type R Pilot Mill and Dressing Tool is extremely

versatile and, in special cases, can be used with over-size

cutting elements

to cut

several sizes

of

casing.

Cutting elements are easily changed on the rig floor.

USE

The A-Z

Dual Rock Type Underreamer

is

used

fo r

drilling

and

underreaming simultaneously in soft formations.

In special app l icat ions,

it can be

used

for

drilling

an d

under-

reaming short sect ions of hard formation, such as sett ing

anchor pi l ing, underwater storage tanks and other marine

structures.

ADVANTAGES

• Combines two operat ions in one —

drilling

and under-

reaming.

• El iminates need for large blowout p reventers.

• Utilizes jet drilling principle.

• One set of cutter arms w ill underream seve ral sizes of hole

by simply changing gauge l inks and piston stop.

•

Cutter arms

can be

easi ly changed

on rig

floor.

.

By combining two operat ions into one, the A-Z Dual Rock

Type Und erreamer s aves r ig t ime whe n sett ing surfa ce casing.

At the same t ime, by el iminat ing the need for large blowout

preventers, t ime

to

nipple

up and

tear down

is

great ly reduce d.

In addition, the rental or purchase price of the large preventers

is eliminated.

Th e exclusive l inkage feature of the A-Z Dual Underreamer

makes i t possible, by simply changing gau ge l inks and piston

stop, to use only on e size cutter arm for al l open ings, a featu re

which reduces cutter inventory.

In addit ion to a jet bi t, the A -Z Dual Un derream er ut i lizes a jet

sub. Nozzles between the cutter arms and rock bit are so

directed that a jet stream of dril ling f luid is in contact w ith each of

the underreamer cones at al l t imes, cleaning these elements

and reducing the tend ency to "ball up" in sticky form ations .

OPERATION

Th e operation of the A-Z Dual Rock

Type

Underreamer is iden-

t ical wi th that of the A-Z

R ock

B i t Under reame r descr ibed on

page 26 of this catalog exce pt that a su f f ic ient volume o f f luid is

uti lized to con form to good jet dr i l l ing pract ices .
