a er an ng n pp es

Two Baker systems Standard and Surset

First we will concentrate on Baker standard equipment

There are two standard landing nipples

Both are nogo landing nipples

Both have a profile, seal bore and nogo

Even though they have nogo shoulders Baker have a selectivesystem due to the lock type


4/32

N N E

a er an ng n pp es

Top nogo landing nipple the nogo is above the

seal bore

ID of the nipple is the seal bore dimension

Will accept the following locks

M,G,F and W

S selective due to lock

All L Sliding side doors have an F nipple profile


5/32

N N E

a er an ng n pp es

Bottom nogo landing nipple the nogo is below

the seal bore

ID of the nipple is the dimension of the nogoshoulder, smaller than seal bore

Will accept the following locks

Z,R,E and K

Always installed below an F nipple of the samenominal size

ow ng an non ow ng app cat ons

Equalizing assemblies can be added to all the

standard locks to form plugs

Gauge carries (bomb hangers) can be addedto two locks to be used in flowing applications

W lock in the top nogo F nipple

Z lock in the bottom nogo R nipple

V packing are attached to Equalizing devices

qua z ng ev ces

Three types used in standard Baker plugs

H Prong type, prong run and set after plug body is set.2 runs to set and 2 runs to pull

G Prong type, prong run with plug body. 1 run to setand 2 runs to pull

R Melon type, 1 run to set and 1 run to pull

Similar probes can havemodifications, e.g.

A & AC probes cannot be

used for the same operation,an AC probe has no internalthread to accept a prong

An M1 Probe has a telltaleshear pin where an M probehas not.

unn ng oo s

C1 used to run W, Z, G,R and Slocks, can be used to run FB & RBstanding valves

E Selective used to run S selectivelocks with all the dogs retracted

G Selective used to run S selectivelocks with up facing dogs trailing

C1 can be used to run the Sselective lock with the up facing dogstrailing


13/32N N E

unn ng oo s

Baker M pulling tool used to run and pull

several locks E, M (locks) and B (safety valve) locks canbe run using the M pulling tool

With this tool the probe is also used to setthe device

E.g. when an M1 probe is used to set

devices, the probe has a shear pin toindicate correct setting

W lock and G equalizing device

Plug hold pressure from above and below

Prong run with plug body 1 run to set

Collet and collet bowl prevent prong moving down

Shear pin (brass) prevents the prong moving up

Run on C1 1 x Aluminum (prong) 2 x Brass (body)

Brass pins through body have 2 options


16/32N

N E

a er sett ng pu ng

Depends on C1 pinning, best to pin allowing for

over-pull, pins below fishing neck RIH set down in nipple, jar down to land on nogo,dogs lock into profile, over pull to confirm

J ar up to shear Brass pins below FN on body, C1moves up pulling prong to sealing position, thenaluminum pin through prong shears

Prong lock in sealing position by collet and colletbowl


17/32N

N E

a er sett ng pu ng

To pull device, pull prong using SB/J DC to equalize,

B probe must be attached to SB/J DC to pull plugbody, B probe collapses the dogs when engaging FN

W2 lock has different dogs, different pivot position

Smaller sized G equalizing assemblies have twopins through the collet bowl sleeve

SB or J DC must be used to pull device as skirt maycontact body preventing shearing off


18/32N

N E

a er

Bottom nogo option for R nipples

Same function as FWG

Same running/pulling procedures as FWG

Because of FN angle and pulling tool OD differenceOtis pulling tool should be used

Ensure equalization before latching lock


19/32N

N E

a er

Plug does not have a nogo shoulder

Can be run using either a C1, G selective or Eselective running tools

Shank holds dogs in running position, prong holdsmelon in equalizing position

When pulling device, Kobe plug on equalizing bodyis broken to allow pressure equalization

a er sett ng pu ng

Run using an A shank and pulled using an AC probe

with an equalizing prong attached C1 with a locator ring to find the F nipple nogoshoulder

G selective tool holds the down facing dogsretracted

Upon location of nipple pick up, up facing dogslocate the profile, half jar up shears C1 pins andreleases down facing dogs locking device in nipple

21/32

N N E

a er sett ng pu ng

To pull the device, an A or AC probe must be used

attached to the pulling tool The probe releases the up facing dogs

After equalization, jar up or over pull to release thedevice

E selective tool holds all dogs retracted, allows forpassing of same sized F nipples, pins on running toolshear to release the upper dogs and setting is as peron previous tools

a er urset equ pment

Standard equipment did not meet pressure rating needs of

the industry New system needed hence Surset was developed

New nipples developed that included pressure ratings

Retain F and R nogo positioning

A 15K

New nipples became AF, HF, VF, AR, HR and VR



25/32

N N E


Locks made to match nipples hence AF went into an

AF nipple, of VR lock matched a VR nipple

Only two equalizing devices use H prong and M melon (sometimes known as R)

One running tool (model A) to run all locks

Can be pulled with Baker M (Otis GS)
