THIS DOCUMENT IS FOR INTERNAL USE ONLY
Effect Of Tubing and A nnul us Pressure
On Unloader
The unloader in the R-3™ Retrievable Casing
Packer is not hydraulically balanced for any
specif-ic tubing size. This means that regardless of what
size tubing the packer is run on, changes in tubing
pressure and annulus pressure will act either to
pump the unloader open (by acting against
set-down weight) or help hold it closed. It is important,
then, to know how much force will be created, and
in what direction, for a given change in annulus or
tubing pressure.
The values given in the chart “Areas (In Sq. In.)
Acted Upon By Tubing and Annulus Pressures”
are printed shaded and unshaded. These values
are not only the number of square inches acted
upon by the pressure change, but also the
direc-tion of the resultant force. The areas unshaded will
cause, with a pressure increase, a force tending to
hold the unloader closed. The areas shown
shad-ed will result in an upward force, or a force tending
to open the unloader. The directions of the forces
hold true if the tubing and annulus pressures at the
tool are increased.
If the tubing pressure at the tool is decreased,
such as would occur in a swabbing operation, the
direction of force as explained above would be
re-versed.
The Balance Sleeve in the R-3 Double-Grip
Packer works in this manner: When the tool is set
and packed off, the groove in the Body just below
the Seal is positioned under the snap fingers of the
Balance Sleeve. As tubing pressure is increased,
pressure acts between the two [2] O-rings on the
Balance Sleeve, causing it to move down. When
the bottom bevel on the outside of the snap fingers
meets the inside bevel in the Balance Sleeve
Housing, the snap fingers are forced inward into
the groove in the Body. Tubing pressure continues
to push the Balance Sleeve down until the inside
bevel on the bottom of the snap fingers meets the
bottom bevel of the groove in the Body. The tubing
pressure which moved the Balance Sleeve down is
now holding, through the snap fingers, the Body
down. This force acts in the same direction as
set-down weight to help prevent the Body from moving
up under high tubing pressures. If the Body were
to move up, the unloader would open and
tubing-to-annulus communication would result.
When the annulus pressure is greater than
tub-ing pressure, the Balance Sleeve is held by the
an-nulus pressure, against the Balance Sleeve
Housing. In this position, the fingers of the Balance
Sleeve do not act to help hold the Body down;
set-down weight alone must be used to keep the
un-loader closed.
It should be noted that the
set-down weight required to keep the unloader
closed need not be added to the weight
re-quired to set the packer if the value calculated
is less than the force required to set the tool.
•
Columns 1, 2, 4, 5, 6, and 7 must be multiplied
by the change in pressure at the tool.
•
Column 3 must be multiplied by the tubing
pressure.
•
Areas tending to hold the unloader closed are
unshaded.
•
Areas tending to open the unloader are
shaded.
•
Multiplying a pressure change by a shaded
figure gives a force tending to open the
unloader.
•
Multiplying a pressure change by an unshaded
figure gives a force tending to hold the unloader
closed.
When Tubing Pressure Is Greater Than
Annulu s Pressur e At The Too l
1. Multiply the
change
in tubing pressure at the
tool by Column 1.
2. Multiply the
change
in annulus pressure at the
tool by Column 2.
If the total of these two forces is tending to open
the unloader, and is greater than the original
pack-off weight, additional set-down weight is
required. This additional weight is equal to the
difference between the force tending to open
the unloader and required pack-off weight.
3. Multiply the tubing pressure by Column 3.
Since the figure in Column 3 is always shaded,
the resulting force is tending to open the
un-loader by lifting the tubing at the surface. If by
adding all three forces the result is a force
tend-ing to open the unloader and is greater than the
maximum hook-load of the tubing before

ting the tool, the tubing will raise and the
un-loader will be opened.
Since the hook-load is
the limiting factor, high pressures at
rela-tively shallow depths might be prohibit ive.
When Annulus Pressure Is Greater Than
Tubing Pressure At The Tool
1. Multiply the
change
in tubing pressure by
Col-umn 4.
2. Multiply the
change
in annulus pressure by
Column 5.
If the total of these two forces is tending to open
the unloader, and is greater than the original
pack-off weight, additional set-down weight is
required. This additional weight is equal to the
difference between the force tending to open
the unloader and the required pack-off weight.
3. Multiply the tubing pressure by Column 3.
Since the figure in Column 3 is always shaded,
the resulting force is tending to open the
un-loader by lifting the tubing at the surface. If by
adding all three forces the result is a force
tend-ing to open the unloader and is greater than the
maximum hook-load of the tubing before
set-ting the tool, the tubing will raise and the
un-loader will be opened.
Since the hook-load is
the limiting factor, high pressures at
rela-tively shallow depths might be prohibit ive.
When Annulus Pressure Is Greater Than
Tubing Pressure At The Tool Due To
Swabbing The Tubing
1. Multiply the
change
in tubing pressure by
Col-umn 6.
2. Multiply the
change
in annulus pressure by
Column 7.
If the result is a force tending to open the
un-loader, and is greater than the original pack-off
weight, additional set-down weight is required.
This additional weight is equal to the difference
between the force tending to open the unloader
and the required pack-off weight.
NOTE:
The above calculations assume the
tub-ing strtub-ing is suspended in the elevators and
slack off weight on packer can be maintained.
Due to factors such as tubing ballooning, and
thermal expansion or contraction, hydraulic
cal-culations alone may not be sufficient to
deter-mine what is happening at the packer. When
working deep at high pressure or with fluid
tem-perature changes, and in cases where the
well-head is flanged up, running the R3DG
TUBEMOVE™ computer program is necessary
to determine if the unloader will remain closed
under the conditions encountered in each
appli-cation.
Pressuring operations from below may not be
possible with the R-3™ Single-Grip Packer.
The calculations outlined on these pages will
only help determine if the unloader will stay
closed. In the case where tubing pressure is
greater than annulus pressure, additional
hy-draulic calculations are necessary to determine
how much slack off weight is required to keep
the R-3 Single-Grip Packer from being
hydrau-lically pumped up the hole.
