RECOMMENDED RUNNING PROCEDURES
BENOIT® BTS® PREMIUM
CONNECTION TUBING
GENERAL
The procedure that follows should be used as a guideline for
handling and running tubing with Benoit® BTS® Premium Connections.
Prior to running, connections should be cleaned (hot water or
steam cleaning without solvents is recommended) and dried with
compressed air.
Apply a thin uniform coating of thread compound to threads and
seals with a brush. Reapply clean dry plastic thread
protectors.
SPECIAL ALLOY
Special Alloy tubulars are highly susceptable to handling
damage. Every effort should be made to minimize metal-to-metal
contact with these materials.
Prior to handling Special Alloy tubulars, all personnel
involved should be briefed on the nature of the product and how
their duties should be conducted.
Prior to running, Special Alloy connections should be cleaned
(hot water or steam cleaning without solvents is recommended) and
dried with compressed air. Apply a uniform coating of Dry
Molly to threads and seals and allow to dry. Apply a thin
uniform coating of thread compound to threads and seals with a
brush. Reapply clean dry plastic thread protectors.
PRE-RUNNING PREPARATION
Tubing Preparation
- While the tubing is on the rack, remove the pin and box end
protectors.
- If a drift test is to be performed, it should be performed
prior to cleaning and inspection. Inspect the drift mandrel to
make certain it conforms to API requirements. Be very careful
to not damage the connections during drifting. Tubulars that will
not pass the drift test should be clearly marked and separated
for further investigation.
- Thoroughly clean and dry the connections. If any debris is
present, repeat the cleaning process. Benoit® recommends the use of a hot water pressure washer or steam
cleaner without solvents for cleaning the connections since this
will leave no residual film.
- Visually inspect the connections for damage.
- Damage that can be field repaired at this time should be. Joints that can not be field repaired should be marked
accordingly and segregated.
- Records should be kept on all repairs or rejects.
- Check the inside of the tubes for dirt or scale. If any is
present remove with compressed air. Blow out tubing from the box
end toward the pin if possible.
- If protective rings ("PR") are to be installed it should be
done at this time. Special installation tools are available for
purchase or rent from Benoit®.
- Clean - dry pin and box protectors should be placed back on
the connections.
Rig Site Preparation
- Check for traveling block and rotary hole alignment.
- Verify that the wear bushing has been pulled or that the I.D.
is sufficient to pass all string components.
- Verify that the B.O.P.s have been fitted with the proper size
pipe rams.
Running and Handling Equipment
- Ensure that the slips are in good working condition, are
fitted with the proper dies, and will accommodate the weight of
the string.
- Ensure that the elevators are in good working condition, are
fitted with the proper size dies, and will accommodate the weight
of the string. Benoit® recommends the use of
slip type elevators. DO NOT use bottleneck elevators.
- The power tongs should be rated for the torque that is to be
applied. They should be fitted with the proper size and type of
dies. The dies must conform to the curvature of the tubing. The
snub line should be at a 90° angle to the tongs and must be
level.
- A calibrated power tong torque gauge should be placed in the
snub line. For optimum performance, run should be approximately
half of the gauge scale. The handle length of the power tongs
should match the handle length for the torque gauge. PSI gauges
are not suitable for running production tubing.
- Hand held or integral hydraulic backups should be used. They should be in working order, fitted with the proper size and
type of dies, and should be rated for the torque that is to be
applied.
- A man on the stabbing board should be utilized to maintain
vertical alignment throughout stabbing and make-up.
- Lift plugs should be utilized for connection protection and
personnel safety. They should be inspected for overall
condition and checked manually to insure proper fit.
- A stabbing guide should always be used to stab the pin into
the box. It should be in good working order and provide adequate
connection protection when stabbing. It should be checked
manually for proper fit.
- Clean, fresh thread compound should be on location in
sufficient quantities. API Modified thread compound is
recommended for carbon, stainless steel, and chrome tubing. BTS® Connections have large positive stop torque
shoulders, therefore a torque correction factor is not necessary
if other than API Modified thread compound is used. For
aluminum use a thread compound with a high zinc content.
- A safety clamp in good working condition and sized for the
tubing and accessories should be available.
- A pickup line in good condition should be used. It may be
constructed of rope or Nylon. Insure that whatever material
used is rated for the weight to be lifted.
- If a rabbit is to be used during the running of the tubing,
it should be measured to ensure the O.D. is the correct size. The rabbit should be constructed of a material such as Teflon.
The rabbit should be manually inserted into the tubing to ensure
proper fit.
- If a pickup / laydown unit is to be used, the pickup arms,
trough and backstop should be coated.
Tubing String Accessories
Note: It is preferable to make in-string accessories
up in assemblies. This can be performed at any assembly makeup
facility. The assembly can be made up to full torque. It may
also be full length drifted and pressure tested. This will
virtually eliminate rig down time and connection damage from
problems associated with different diameters and accessory
lengths.
- All accessories that are to be part of the tubing string
should be located and checked against the string design.
- Any accessories that are not present, or do not conform to
the string design should be brought to the attention of the
appropriate end user representative.
- All accessories that are similar, yet slightly different,
should be noticeably marked to indicate the position that they
are to be run in the string.
- If possible, all accessories should be drifted. Accessories
with restricted I.D.s may also be drifted if arrangements have
been made to have reduced size mandrels present.
- Note if any accessories will require additional make-up or
handling equipment.
- Thoroughly clean and dry all the accessory connections.
- Visually inspect the connections for damages.
- Damages that can be field repaired at this time should
be.
- Any connections that cannot be field repaired should be
marked accordingly and set aside. Replacement accessories
should be ordered or the damaged parts should be rethreaded.
- If protective rings ("PR") are to be installed they should be
installed at this time. Special installation tools are
available for purchase or rent from
Benoit®.
- Clean - dry protectors should be placed back on the
connections.
RUNNING AND PULLING
Running
- Gently roll one joint at a time into the pickup trough after
making sure that thread protectors are in place. Transport the
joint to the rig floor.
- Remove the box end protector.
- Install a clean lift plug on the box connection. This will
reduce the possibility of the tube slipping out of the pickup
line and reduce the possibility of the test tool or elevators
damaging the connection.
- If the tubing is to be rabbited, the rabbit should be placed
in the tubing after installation of the lift plug. If the
rabbit is not clean, it should be cleaned and dried prior to
placing it in the joint. Should the rabbit stop in the tube, it
should be broken free by easily pushing or tapping an object from
either end. DO NOT beat or tap the outside or end of the tubing
with any hard object.
- Attach the pickup line and raise the joint at a moderate
speed, for both safety and tubular protection.
- Remove the pin end protector, and rabbit, and inspect the pin
connection.
- If any debris is present, the pin connection should be wiped
or blown clean.
- Apply a thin even coating of thread compound to the entire
pin thread and seal areas using a brush.
- Remove the lift plug from the box end in the rotary.
- If debris is present, the box connection should be wiped or
blown clean.
- Apply a thin even coating of thread compound to the box
thread and seal areas.
- Place the stabbing guide over the box end connection.
- Slack off of the joint in the pick up line. The joint
should be lowered slowly to minimize starting thread damage
during stabbing.
OPTIONAL: Prior to
stabbing connections on aluminum, chrome, or stainless steel
tubing; vertically mark the upset of the pin & box in line with
the thread starts. Rotate the pin tube so that the mark is
approximately 1/4 turn counterclockwise from the mark on the box
tube and gently stab the pin into the box. See figures 1-4. This will allow the threads
to start immediately, thus reducing the chances of
galling.
- The pipe must be in true vertical alignment over the box and
under complete control before stabbing. Do not rock the pipe to
stab.
- Remove the stabbing guide and the pick up line.
- Make up the connections by hand or with a strap wrench,
leaving 1/2 to 1 turn before shouldering.
- Apply the power tongs and makeup to recommended torque at no
more than five RPM. Tongs and backups must be positioned
sufficiently above and below connections so as not to pinch or
otherwise deform the connections. If torque is achieved
prematurely, stop makeup immediately and check vertical
alignment. Attempt makeup again. If premature torque is still
present, back out the connection and check for damage. Repair
or lay the joint aside and proceed. Apply BTS® recommended torque as per Benoit® specification.
- Remove the power tongs.
- If testing above the rotary, insert the internal test tool or
apply the external test unit. Test only after full
torque has been applied to the connections.
- After full torque has been achieved, latch the elevators as
gently as possible and raise the block at a slow speed. If the
block is raised too rapidly, stretching or necking of the tubing
might occur.
- Pull the slips and lower the string.
- Stop downward movement of the string and either set the slips
or firmly hold them around the tubing. Make certain that the
slips are set or placed correctly. Gently set the string weight
on the slips. Applying weight too rapidly may cause the tubing
to stretch or neck-down in the slips.
- Attach the pickup line to the next joint to be run and
unlatch the elevators from the last joint run. Hold the
elevators far enough away from the joint in the rotary to prevent
contact and raise the block at a moderate speed.
- If the tubing is to be tested below the rotary, insert the
internal test tool. To prevent connection damage, leave the
handling plug completely made up until the test tool has been
removed from the tubing.
Pulling Singles *
*Pulling and running production tubing in stands is
not recommended.
- Install a lift plug onto the joint in the rotary and gently
latch the elevators around the joint. Raise the block at a slow
and even speed.
- Stop movement of the string and either set the slips or
firmly hold them around the tubing. Assure that the slips are
set or placed correctly. Gently set the string weight on the
slips.
- Unlatch the elevators and raise them above the joint to be
backed out.
- Have the stabber hold the joint to be backed out as close to
true vertical as possible.
- Apply the power tongs and, in low gear, slowly apply torque
until the connections break. Back out the connections at
approximately 5 RPM. Do not break out with connection in
tension.
NOTE: For aluminum, chrome and stainless steel
connections: After initial break, rotate the connection
approximately 1/4 turn, unlatch the power tongs and continue
break-out by hand or with a strap wrench until the connection
"hops" once.
- Attach the pickup line.
- Latch the stabbing guide around the box end to reduce jump
out damage.
- Gently raise the joint. If the connection does not appear
to be free, turn counter clockwise one half turn and try to lift
again.
- Dope the pin connection thoroughly and install a clean thread
protector.
- Slowly set the joint in the vee door.
- Remove the pickup line and the lift plug.
- Dope the box connection thoroughly and install a clean thread
protector.
