Description
BACKGROUND
[0001] Tubular systems, such as those used in the completion and
carbon dioxide sequestration industries often employ anchors to
positionally fix one tubular to another tubular, as well as seals
to seal the tubulars to one another. Although existing anchoring
and sealing tools and systems for setting such tools serve the
functions for which they are intended, the industry is always
receptive to new systems and methods for anchoring and sealing
tubulars.
BRIEF DESCRIPTION
[0002] Disclosed herein is a treatment plug setting tool. The tool
includes a shank, a collet attached to the shank, and a sleeve
attached to the shank that is positioned and configured to provide
longitudinally compressive support to fingers of the collet while
allowing the fingers to radially deflect.
[0003] Further disclosed herein is a method of preventing actuation
of a setting tool while running the setting tool through a tubular.
The method includes, longitudinally supporting a collar of the
setting tool through protruding portions of fingers of a collet and
a perimetrically continuous portion of a sleeve attached to a
shank, and preventing actuatingly moving the collar of the setting
tool relative to other components of the setting tool.
[0004] Further disclosed herein is a treatment plug and setting
system. The system includes, a treatment plug having, a cone, at
least one slip in operable communication with the cone that is
radially movable in response to longitudinal movement relative to
the cone, and a collar configured to prevent longitudinal movement
of the at least one slip when the cone is moving relative thereto.
The setting system further includes a setting tool having, a shank,
a collet attached to the shank, and a sleeve attached to the shank
that is positioned and configured to prevent disconnection of the
setting tool from the treatment plug until after a releasable
member in operable communication with both the sleeve and the
collar has been released.

elements are numbered alike:
[0006] FIG. 1 depicts a cross sectional view of a treatment plug
and setting tool system disclose herein; and
[0007] FIG. 2 depicts a perspective view of the setting tool shown

DETAILED DESCRIPTION
[0008] A detailed description of one or more embodiments of the
disclosed apparatus and method are presented herein by way of
exemplification and not limitation with reference to the
Figures.
[0009] Referring to FIGS. 1 and 2, an embodiment of a treatment
plug setting system is illustrated at 10. The system 10 includes a
treatment plug 14 and a setting tool 18. The treatment plug 14 has
a cone 22, a plurality of slips 26 and a collar 30. The slips 26
abut the collar 30 and are configured to move with the collar 30
longitudinally relative to the cone 22. Such movement causes the
slips 26 to move radially (outwardly in the embodiment illustrated)
and into engagement with a structure 34 shown herein as a casing or
liner of a borehole in a hydrocarbon recovery completion, for
example. Optional, teeth 38 on a surface 42 of the slips 26 bite
into the structure 34 to fixedly attach the slips 26 and the bride
plug 14 to the structure.
[0010] The setting tool 18 includes a shank 46, a collet 50 and a
sleeve 54. Both the collet 50 and the sleeve 54 are attached to the
shank 46 by threads 58 and 62, respectively, in this embodiment. An
end of the sleeve 54 has a perimetrically continuous wall 70
providing hoop strength to resist radial deformation thereof. The
wall 70 and protrusions 74 on fingers 78 of the collet 50 are
positioned longitudinally between a releasable member 82, shown
herein as a shear ring attached to the collar 30, and a shoulder 84
on the collar 30. The wall 70 provides longitudinal support to the
fingers 78 through the protrusions 74 against loads applied to the
protrusions 74 from the shoulder 84. This support from the wall 70
prevents the fingers 78 from deforming under compressive loading as
might otherwise occur if the collar 30 momentarily catches on the
structure 34 during running therethrough. When loading is reversed,
angled surfaces 86 on the protrusions 74 are configured to ramp
against a complementary surface 90 on the collar 30 to urge the
fingers 78 to deflect radially inwardly only after release of the
releasable member 82. The radial deflection of the fingers 78
allows the setting tool 18 to release from the treatment plug 14
and to subsequently be retrieved, for example, to surface.
[0011] The releasable member 82 is strong enough to resist
releasing while being loaded during the setting of the treatment
plug 14. During setting of the treatment plug 14 the cone 22 is
moved relative to the slips 26 and the collar 30 thereby causing
the slips 26 to expand radially outwardly. This action causes
longitudinal loading of the collar 30 that is supported through the
releasable member 82 via contact with the continuous wall 70 of the
sleeve 54 that is attached to the shank 46. A longitudinal
dimension 94 of the continuous wall 70 is sized to prevent contact
between the angled surfaces 86 and the surface 90 until after
release of the releasable member 82. Only after the releasable
member 82 releases the angled surfaces 86 can contact the surface
90 causing the fingers 78 of the collet 60 to deflect allowing
disconnection of the setting tool 18 from the treatment plug 14. It
should be noted that although both of the angled surfaces 86 and
the surface 90 are oriented to cause the fingers 78 to deflect
radially, ramping forces would still be generated on the fingers 78
even if only one or the other of the surfaces 86 and 90 were
angled.
[0012] Optionally the treatment plug 14 may include a seal 100
configured to sealingly engage with the structure 34 when actuated.
Actuation of the seal 100 occurs in a similar fashion to that of
the slips 26. A tapered member 104 is moved relative to a tubular
108 that is radially supportive of a seal element 112, which may be
made of a ductile material such as a polymer. This movement of the
tapered member 104 causes radial expansion of the tubular 108 that
causes radial expansion of the seal element 112 into sealing
engagement with the structure 34. The tubular 108 may be made of
metal or other material that plastically deforms to retain the seal
element 112 in sealing engagement even if the tapered member 104 is
moved in a reversed direction. Alternate embodiments could have the
tapered member 104 engage with the seal element 112 direction
without the tubular 108 positioned therebetween. As with the
setting of the slips 26 the setting of the seal 100 also causes
loading on the collar 30 through the releasable member 82. This
loading can be greater, or less than that generated during setting
of the slips 26. Regardless of the loads applied to the collar 30
during the setting of the either or both of the slips 26 and the
seal 100 the releasable member 82 is configured to not release
until after both the slips 26 and the seal 100 are fully set.
[0013] Additionally, the treatment plug 14 may include a ratcheting
mechanism 116 that has teeth 120 on the cone 22 that ratchetingly
engage with teeth 124 on the collar 30 to maintain slips 26 in a
position on the cone 22 to assure that the slips 26 sufficiently
remain engaged with the structure 34 even after loads that move the
cone 22 relative to the slips 26 has been removed.
[0014] While the invention has been described with reference to an
exemplary embodiment or embodiments, it will be understood by those
skilled in the art that various changes may be made and equivalents
may be substituted for elements thereof without departing from the
scope of the invention. In addition, many modifications may be made

Therefore, it is intended that the invention not be limited to the
particular embodiment disclosed as the best mode contemplated for
carrying out this invention, but that the invention will include
all embodiments falling within the scope of the claims. Also, in
the drawings and the description, there have been disclosed
