Definitions
- a typical sealing assembly (e.g., packer, bridge plug, etc.) generally has one or more sealing elements or “rubbers” that are employed to provide a fluid-tight seal radially between a mandrel of the sealing assembly and the casing or wellbore into which the sealing assembly is disposed.
- Such a sealing assembly is commonly conveyed into a subterranean wellbore suspended from tubing extending to the earth's surface.
- the sealing elements are carried on the mandrel in a relaxed or uncompressed state in which they are radially inwardly spaced apart from the casing.
- the sealing elements radially expand (e.g., both radially inward and radially outward), thereby sealing against the mandrel and the casing and/or wellbore.
- the sealing elements are axially compressed between element retainers straddling the sealing elements on the seal assembly, which in turn radially expand the sealing elements.
- one or more swellable sealing elements are axially positioned between the element retainers, the swellable sealing elements configured to radially expand when subjected to one or more different activation fluids.
- the seal assembly often includes one or more slip rings, which grip the casing and prevent movement of the seal assembly axially within the casing after the sealing elements have been set.
- the slip rings resist the axial forces on the seal assembly produced thereby, and prevent axial displacement of the seal assembly relative to the casing and/or wellbore.
- FIG. 1 illustrates a well system designed, manufactured, and operated according to one or more embodiments of the disclosure, the well system including a sealing tool including a sealing assembly designed, manufactured, and operated according to one or more embodiments of the disclosure;

- connection Unless otherwise specified, use of the terms “connect,” “engage,” “couple,” “attach,” or any other like term describing an interaction between elements is not meant to limit the interaction to direct interaction between the elements and may also include indirect interaction between the elements described.
- use of the terms “up,” “upper,” “upward,” “uphole,” “upstream,” or other like terms shall be construed as generally toward the surface of the ground; likewise, use of the terms “down,” “lower,” “downward,” “downhole,” or other like terms shall be construed as generally toward the bottom, terminal end of a well, regardless of the wellbore orientation. Use of any one or more of the foregoing terms shall not be construed as denoting positions along a perfectly vertical axis.
- use of the term “subterranean formation” shall be construed as encompassing both areas below exposed earth and areas below earth covered by water such as ocean or fresh water.
- c-ring slip rings which often contain a single axial slot therein (e.g., aligned with Figs a centerline (C L ) of the slip ring), do not provide 360-degree contact between the packer and the surrounding tubular when in the radially enlarged state.
- C L centerline
- the exposed region may cause the packer to cantilever within the surrounding tubular, as well as creates misalignment between related upper and lower c-ring slip rings, which are both undesirable.
- the present disclosure has recognized that the undesirable cantilever effect may be reduced, if not eliminated, if there is 360-degree contact between the packer and the surrounding tubular when the slip ring is in the radially enlarged state.
- the present disclosure has further recognized that the 360-degree contact may be achieved with a slip ring employing a slot that is misaligned with the centerline (C L ) of the slip ring.
- the present disclosure has recognized that the 360-degree contact may be achieved using a slip ring employing a slot extending between a first end and a second opposing end of a ring member, wherein a first portion of the slot located at the first end and a second portion of the slot located at the second opposing end are radially offset from one another by at least 15-degrees.
- the slot may take on many different shapes while achieving the discussed radially offset, including both non-linear and linear slots.
- the slot is a non-linear slot, such as a Z-shaped slot, an S-shaped slot, a spiral shaped slot, or a helical shaped slot, among others.
- the slot is a linear slot, such as a linear slot extended from the first end to the second opposing end at an angle.
- a slip ring designed, manufactured, and used according to the present disclosure will allow for 360-degree contact between the packer and the surrounding tubular, even when in the radially enlarged state, without the need for a full barrel style type external slip ring.
- Full barrel style type external slip rings are expensive to manufacture.
- a slip ring according to the disclosure can be manufactured generally using the same processes used to manufacture typical c-ring slip rings (with the exception of the process used to form the slot), which is much less expensive. Accordingly, the slip ring of the present disclosure could be used as a direct replacement for existing c-ring slip rings with a slot of all sizes and weight ranges, and thus may be readily used in certain low-cost commodity packers.

Abstract
Description
- A typical sealing assembly (e.g., packer, bridge plug, etc.) generally has one or more sealing elements or “rubbers” that are employed to provide a fluid-tight seal radially between a mandrel of the sealing assembly and the casing or wellbore into which the sealing assembly is disposed. Such a sealing assembly is commonly conveyed into a subterranean wellbore suspended from tubing extending to the earth's surface.
- To prevent damage to the sealing elements while the sealing assembly is being conveyed into the wellbore, the sealing elements are carried on the mandrel in a relaxed or uncompressed state in which they are radially inwardly spaced apart from the casing. When the sealing assembly is set, the sealing elements radially expand (e.g., both radially inward and radially outward), thereby sealing against the mandrel and the casing and/or wellbore. In certain embodiments, the sealing elements are axially compressed between element retainers straddling the sealing elements on the seal assembly, which in turn radially expand the sealing elements. In other embodiments, one or more swellable sealing elements are axially positioned between the element retainers, the swellable sealing elements configured to radially expand when subjected to one or more different activation fluids.
- The seal assembly often includes one or more slip rings, which grip the casing and prevent movement of the seal assembly axially within the casing after the sealing elements have been set. Thus, if weight or fluid pressure is applied to the seal assembly, the slip rings resist the axial forces on the seal assembly produced thereby, and prevent axial displacement of the seal assembly relative to the casing and/or wellbore.
- Reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
-

FIGS. 6A through 6D illustrate alternative views of an alternative embodiment of a slip ring designed, manufactured, and operated according to an embodiment of the disclosure; and -
FIGS. 7A and 7B illustrate various different deployment states for a sealing assembly designed, manufactured, and operated according to an embodiment of the disclosure. - In the drawings and descriptions that follow, like parts are typically marked throughout the specification and drawings with the same reference numerals, respectively. The drawn figures are not necessarily to scale. Certain features of the disclosure may be shown exaggerated in scale or in somewhat schematic form and some details of certain elements may not be shown in the interest of clarity and conciseness. The present disclosure may be implemented in embodiments of different forms.
- Specific embodiments are described in detail and are shown in the drawings, with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that illustrated and described herein. It is to be fully recognized that the different teachings of the embodiments discussed herein may be employed separately or in any suitable combination to produce desired results.
- Unless otherwise specified, use of the terms “connect,” “engage,” “couple,” “attach,” or any other like term describing an interaction between elements is not meant to limit the interaction to direct interaction between the elements and may also include indirect interaction between the elements described. Unless otherwise specified, use of the terms “up,” “upper,” “upward,” “uphole,” “upstream,” or other like terms shall be construed as generally toward the surface of the ground; likewise, use of the terms “down,” “lower,” “downward,” “downhole,” or other like terms shall be construed as generally toward the bottom, terminal end of a well, regardless of the wellbore orientation. Use of any one or more of the foregoing terms shall not be construed as denoting positions along a perfectly vertical axis. Unless otherwise specified, use of the term “subterranean formation” shall be construed as encompassing both areas below exposed earth and areas below earth covered by water such as ocean or fresh water.
- The present disclosure has acknowledged that typical c-ring slip rings, which often contain a single axial slot therein (e.g., aligned with Figs a centerline (CL) of the slip ring), do not provide 360-degree contact between the packer and the surrounding tubular when in the radially enlarged state. Specifically, as the axial slot widens when the slip ring moves from the radially reduced state to the radially enlarged state, an exposed region exists where there is no contact between the packer and the surrounding tubular. The present disclosure has further acknowledged that the exposed region may cause the packer to cantilever within the surrounding tubular, as well as creates misalignment between related upper and lower c-ring slip rings, which are both undesirable.
- Based upon the foregoing acknowledgments, the present disclosure has recognized that the undesirable cantilever effect may be reduced, if not eliminated, if there is 360-degree contact between the packer and the surrounding tubular when the slip ring is in the radially enlarged state. The present disclosure has further recognized that the 360-degree contact may be achieved with a slip ring employing a slot that is misaligned with the centerline (CL) of the slip ring. For example, the present disclosure has recognized that the 360-degree contact may be achieved using a slip ring employing a slot extending between a first end and a second opposing end of a ring member, wherein a first portion of the slot located at the first end and a second portion of the slot located at the second opposing end are radially offset from one another by at least 15-degrees. The slot may take on many different shapes while achieving the discussed radially offset, including both non-linear and linear slots. In at least one embodiment, the slot is a non-linear slot, such as a Z-shaped slot, an S-shaped slot, a spiral shaped slot, or a helical shaped slot, among others. In yet another embodiment, the slot is a linear slot, such as a linear slot extended from the first end to the second opposing end at an angle.
- Therefore, a slip ring designed, manufactured, and used according to the present disclosure will allow for 360-degree contact between the packer and the surrounding tubular, even when in the radially enlarged state, without the need for a full barrel style type external slip ring. Full barrel style type external slip rings are expensive to manufacture. Moreover, a slip ring according to the disclosure can be manufactured generally using the same processes used to manufacture typical c-ring slip rings (with the exception of the process used to form the slot), which is much less expensive. Accordingly, the slip ring of the present disclosure could be used as a direct replacement for existing c-ring slip rings with a slot of all sizes and weight ranges, and thus may be readily used in certain low-cost commodity packers.

In the embodiment ofFIGS. 2A through 2D , theslip ring 200 additionally includes a plurality ofteeth 230 extending from thering member 210. In at least one embodiment, the plurality ofteeth 230 are configured to grip a bore (e.g., tubular) located outside of thering member 210 when thering member 210 is in a radially enlarged state. While a plurality ofteeth 230 are illustrated inFIGS. 2A through 2D , other embodiments may employ different shaped protrusions. - In the embodiment of
FIGS. 2A through 2D , theslip ring 200 additionally includes one or more reduced thickness notched 240 located in thering member 210. The one or morereduced thickness notches 240 are configured to allow thering member 210 to more easily flex between a radially reduced state and a radially enlarged state. The embodiment ofFIGS. 2A through 2D illustrate thering member 210 having four reducedthickness notches 240, for example radially offset from each other by 90-degrees. Nevertheless, the number and orientation of the reducedthickness notches 240 may vary while still remaining within the scope of the disclosure. Moreover, certain embodiments may exist wherein thering member 210 does not include any reducedthickness notches 240. - The
slip ring 200 ofFIGS. 2A through 2D additionally includes aslot 250 located entirely through the wall thickness (t) and extending between thefirst end 220 and the secondopposing end 225. In at least this embodiment, theslot 250 is configured to allow thering member 210 to move between the radially reduced state (e.g., as shown) and the radially enlarged state (e.g., not shown). In accordance with one or more embodiments, a first portion of theslot 250 located at thefirst end 220 and a second portion of theslot 250 located at the second opposing end are radially offset from one another by at least 15-degrees. In accordance with one or more embodiments, the first portion of theslot 250 located at thefirst end 220 and the second portion of theslot 250 located at the second opposing end are radially offset from one another by at least 30-degrees. In accordance with one or more embodiments, the first portion of theslot 250 located at thefirst end 220 and the second portion of theslot 250 located at the second opposing end are radially offset from one another by at least 45-degrees. In accordance with another embodiment, the first portion of theslot 250 located at thefirst end 220 and the second portion of theslot 250 located at the second opposing end are radially offset from one another by at least 90-degrees.

In even yet another embodiment, theslot 250 makes more than one full revolution around thering member 210, and thus is radially offset from one another by substantially more than 360-degrees (e.g., if theslot 250 were spiral shaped or helically shaped). - The
slot 250 may take on many different shapes while achieving the aforementioned radial offset. In at least one embodiment, such as shown, theslot 250 is a non-linear slot. However, in other embodiments, theslot 250 is a liner slot. In the embodiment ofFIGS. 2A through 2D , theslot 250 is a non-linear Z-shaped slot. For example, theslot 250 ofFIGS. 2A through 2D includes a first portion extending from thefirst side 220 in a direction substantially parallel with the centerline (CL), a second portion extending in a direction not substantially parallel with the centerline (CL) (e.g., substantially perpendicular with the centerline (CL)), and a third portion extending from the second portion in a direction substantially parallel with the centerline (CL) and toward the secondopposing side 225. Accordingly, theslot 250 forms a (e.g., modified) Z-shaped slot. The second portion of theslot 250 is illustrated at approximately a center point of the width (w) of thering member 210, but such is not required. While theslot 250 is illustrated is a Z-shaped slot, as will be illustrated below, other shaped slots are within the scope of the disclosure. - Turning to
