Single String Retrievable Hydraulic / Hydrostatic Set
Premier® Cut Release Removable Production Packer,
Sizes 9-5/8 x 5-1/2 and 4-1/2"
Product Family No. H78463
Introduction
Baker Oil Tools’ new large bore packer delivers
the advantages of the industry’s best permanent
and retrievable packers. The Premier® Removable Production Packer is a new class of “removable” packers for wells that demand the sealing
performance of a permanent packer and the flexible workover options of a traditional retrievable
packer.
The new, hydraulic set Premier Removable
Production Packer combines the performance and
reliability of the S™ Series Retainer Production
Packers with the retrievability of the Reliant Series
Packers.
The Premier Removable Production Packer is
a hydraulic set, large bore retrievable packer. The
Premier and its tailpipe assembly are removed
from the well on the production tubing by mechanically or chemically cutting the packer mandrel.
The Premier Packer comes in two basic configurations: 1) Premium thread, box x pin, or 2) LH
Square Thread with sealbore x premium pin. The
first configuration allows threading the packer directly to the tubing, while the second configuration
provides workover flexibility so the tubing can be
disconnected via an anchor type seal assembly
from the upper sealbore of the packer. With the appropriate completion design, either configuration
can be retrieved on the production tubing using a
Baker Atlas chemical cutter. Alternatively, the second configuration can be retrieved on the workstring using a Premier Workstring Retrieving
(POWER™) Tool (Product Family No. H78464).

consult the attached performance rating envelope
to ensure that the plotted coordinate (pressure,
force) is inside the envelope.
Running Instructions
It is suggested that pup joints be made up
above and below the packer for handling purposes.
Run the appropriate tubing tailpipe and make up
the Premier packer to the top of the string. The tailpipe assembly must contain a means to plug the
tubing. This may be a Baker seating nipple or a
shear-out plug. Run the packer into the well, slowly
installing tubing.

Once at setting depth, land the tubing into the
wellhead hanger and install the plugging device
below the packer. Slowly apply internal pressure to
the tubing string, up to the calculated setting pressure. The pressure required to set the packer is
shown in the chart below.
above the packer. The OD and ID of the cutting
zone are based on tubing dimensions. This should
help in selecting the proper chemical cutting configuration. The use of a radioactive tag run on the
original completion is recommended as a means of
locating the cutting zone of the packer.
There are two [2] main shearing events which
might be observed at surface. The setting sequence will be initiated by the first shear, which will
set the debris barrier, followed by the upper slips,
and then the packing element system. The final
shear sets the lower slips. The pressure for these
events is shown below.
A Baker Atlas Chemical Cutter should be run on
an appropriately designed wireline tool string consisting of weight bars, collar locator, firing sub, upper propellant sub, slip sub, lower propellant sub,
chemical cylinder, cutting head and bull plug. The
chemical cutter can be run with a collar locator or
gamma ray correlation device. It is recommended
in this application to run a collar log to tie-in to the
bottomhole assembly. Care should be given when
running the bottomhole assembly to take accurate
length, ID, and OD measurements of the packer,
pipe, and crossover connections. One should allow enough space below the desired cutting area
for the collar locator or correlation device to pass
below the cutting area to ensure accurate depth
correlation. The chemical cutter is anchored by a
button type slip, which anchors the tool during the
cutting operation. Once the cutting operation is
completed the slips retract and the cutting tool is
free to be pulled from the well.

Once the pressure reaches the maximum setting differential, hold it for ten [10] minutes to ensure all components of the packer are fully
deployed. Bleed off the tubing and test the packer.
Remove the plugging device from the tubing by appropriate means.
Retrieving Instructions
Equalize the pressure above and below the
packer by opening sliding sleeves or cutting holes
in the tubing. To retrieve the packer and tailpipe,
the packer mandrel must be cut.
Two methods of retrieval are available depending on the geometry of the completion: 1) Retrieval
on the completion string via a thru-tubing cut, and/
or 2) retrieval on the workstring via a packer cutting/retrieving tool. In either case, once the mandrel is cut, upward movement of the tubing will
release and stretch out the slips and rubber element of the packer. The packer should come free
with less than 50,000 lb upstrain.
NOTE: The tailpipe rating after retrieval is 250,000 lb.
Retrieval on Completion String
Thru-Tubing, Chemical Cut
In non-restrictive ID completions, chemical cutting is the primary method of removing the Premier® Packer. This cutting method is applicable
only when the OD of the pre-determined cutting
assembly can pass through all the restrictions
Once activated, the chemical cutter will cut
cleanly through the packer mandrel allowing the
packer and tailpipe to be retrieved. In stacked
packer applications, all the packers can be retrieved on the production tubing simply by cutting
all the packer mandrels.
Thru-Tubing, Mechanical Cut
In restricted ID type completions, coiled tubing
conveyed mechanical cutting allows retrieval of the
Premier packer on the completion string. This cutting method must be pre-designed into the original
completion as it requires the use of a Thru-Tubing
Cutting Extension (TCE). The TCE, placed above
the Premier packer, allows the cutting bottomhole
assembly to locate and position itself across the
cutting zone of the packer.
A Baker Oil Tools DB™ Underreamer should
be run on an appropriately designed coil tubing
tool string consisting of a connector, dual flapper
back pressure valve, hydraulic disconnect, dual
actuated circulation sub, adjustable no-go locating
sub and mud motor. The adjustable no-go locating
sub will be spaced out with the DB Underreamer to

place the cut in the required location. Care should
be given when running the bottomhole assembly to
take accurate length, ID, and OD measurements of
the packer, pipe, and crossover connections. One
should allow enough space above the desired cutting area for the adjustable no-go locating sub to
locate and still provide sufficient distance for the
mud motor and the DB™ Underreamer.
The adjustable no-go locating sub is the only
mechanism required to provide for set-down
weight of the coil tubing and accurate location of
the DB™ Underreamer and the subsequent cut of
the packer mandrel.
Once the cutting operation is completed, the
cutting knives retract into the DB Underreamer and
the entire bottomhole assembly is removed from
the well.
by the Baker Engineer on site. Continue the cutting
process until a positive pressure drop has been
observed. This will indicate the cut has been
made. Once the mandrel is cut, upward movement
of the workstring will release and stretch out the
slips and packing element system. The packer
should come free with less than 50,000 lb upstrain.
In stacked packer applications, additional cuts
will be required to sever all the packer mandrels
before the packers can be retrieved.

Retrieval on Workstring
This method of retrieval can only be used when
the Premier® Packer is run with an alternate upper
sealbore.
Cut-to-Retrieve Tool
To use the workstring conveyed retrieving tool,
the anchor type seal assembly must be removed
from the upper sealbore of the packer. A Premier
Workstring Retrieving (POWER™) tool is run in on
an appropriately designed workover string consisting of jars, drill collars, a DB underreamer, and if
rotation of the pipe is not possible, a down-hole
motor. See chart for proper POWER tool usage.
Upon reaching the upper sealbore receptacle,
the tool enters the packer bore and is automatically
positioned for mechanical cutting. Apply 10,000 lb
set-down weight to ensure that the anchor latch
positively engages the left-hand thread in the sealbore receptacle. Gradually bring the pump rate up
to the flow rate and RPM, which was determined
In the event the packer can not be retrieved using standard retrieving procedures, the packer can
be milled over and retrieved.
Baker “Wilson Type M J-Joint” (Product Family
No. H14133) can be used in conjunction with a
washover assembly to burn over and retrieve the
Premier packer in one trip. Run in the hole with the
washover assembly and appropriately sized METAL MUNCHER® Milling Shoe. Mill down to the
slips or until the packer moves downhole. Pull out
of the hole with the washover assembly and recovered packer.
