CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Application No. 17/940505, filed on September 8, 2022, which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] In the resource recovery and fluid sequestration industries there is often need to install tools that expand in the downhole environment. These can be packers, sand screens, etc. Deployments of such tools are commonplace, but all suffer when a control line is to be run outside of an element of the tool. Control lines are run in this way so that they are near the outside diameter of the tool when fully deployed such as in contact with or near the sand face of an open hole, and/or to allow continuous lines as opposed to cut lines running through equipment and then having splices (that increase time and potentially reduce reliability), for example. The art struggles with such deployments and therefore would well receive alternative constructions and methods for similar deployments.

DETAILED DESCRIPTION

[0018] 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.

[0019] Referring to Figures 1A and IB, a basic view of a tool 10 of the type disclosed herein is illustrated. The tool 10 includes an expandable component 12 that may be a packer element or a filtration element, for example. The element 12 is expandable in its radial dimension due to being formed of a shape memory polymer, a swellable material, a rubber material, deformable metal, etc. Also illustrated is a control line 14, that may be an electric line, an optic fiber line, a hydraulic line, combinations including one or more of the foregoing, etc. For example, a hydraulic line might be used for control, chemical injection, etc. while an electrical line might be used for monitoring or control). A fiber optic line might be used for monitoring, distributed temperature sensing or distributed acoustic sensing, for example. The line 14 is retained at one or more clamps 16 (disposed at end rings or between elements or within a span of elements) during run in. [0020] The retention of control line 14 changes upon deployment pursuant to configurations disclosed herein. While a line 14 is characteristically robustly retained on tools 10 run in a borehole 18 to prevent damage during running, that very retention can become a problem during deployment. Comparing Figures 1 A and IB, one can easily perceive that were the line 14 held fast at clamp 16, it would be loaded quite strongly by the expanding element 12. Generally, control lines have greater tensile strength than elements 12 have internal pressure. Commonly then the line 14 will win and the element 12 will be damaged. It is also possible in some cases, however, that the line 14 could be bent or in some way degraded that would impact its function. Either condition is deleterious to the functionality of the tool 10 and hence detractive to the borehole system 50 in which the tool 10 is employed. In accordance with the teaching hereof, these drawbacks are avoided using clamps as disclosed herein.

[0021] Referring to Figures 2-3, a first embodiment of clamp is illustrated. In this embodiment, the clamp 16 comprises a body 20 and a recess or contact surface 22 configured to engage the control line 14. The body 20 comprises, at least in part, a material that is itself expandable or degradable. The material may be the same material as the element 12 (shape memory polymer, or a swellable material, for example) or may be different in various embodiments. The material of the portion of the body 20 may also be composed of degradable material such as controlled electrolytic metallic material (available from Baker Hughes), other metallic materials known to degrade rapidly when exposed to particular fluids such as aluminum, zinc, magnesium, etc., polyglycolic acid, polyvinyl acetate, or polylactic acid to name a few. It is also contemplated that the body 20 is constructed to two different polymers adhered together such that a weakness is inherent at the interface of the two polymers. This could be accomplished through traditional formation or additive manufacture.

[0022] In any of these configurations, the material of the at least a portion of the body 20 may also be configured to react simultaneously, more quickly or more slowly to the same input that causes the element 12 to react or may react differently to that same input. For example, a reaction fluid that causes a shape memory polymer of the element 12 to expand may cause a material of the body 20 to degrade. In the event the material of the at least a portion of the body 20 reacts to a different input than the input to which element 12 reacts, then in some embodiments, the input will be applied or allowed prior to the time that the input to which element 12 reacts is applied or allowed. Inputs to which the element 12 or body 20 react include borehole parameters such as temperature, pressure (ambient or applied), and type of fluid in the borehole 18 along with the amount of time of exposure to that fluid, applied fluids such as for example a acids, solvents, brines, oils, alcohol, ketones, etc. and combinations including one or more of the foregoing. In all cases, the result is that the control line is displaced with the element 12 rather than hindered by the clamp 16.

[0023] Still referring to Figures 2-3, the body 20 is illustrated in a first condition in Figure 2 where it is compacted and retaining the line 14 therein in the appropriate position (analogous to the position in Figure 1A). In the Figure 3 view, the body 20 has expanded and shifted the line 14 away from a center axis of the tool 10. Hence the line 14 is permitted to assume the position analogous to Figure IB. Each of the expanding embodiments referenced above are illustrated schematically by these views.

[0024] Referring to Figure 3A, an alternative arrangement allows body 20 to be metallic and non-responsive to the input (or it could be additionally responsive to the input) and a fastener 21 secures the body 20 to another structure. The fastener 21 may comprise in at least a portion thereof, a material responsive to the input. The fastener may be weakened or degraded or may completely disappear in response to the input. Upon the fastener responding to the input, the body will be unsecured and the control line 14 will be free to move with the element.

[0025] Alternatively, referring to Figures 4 and 5, the body 20 may be configured to release the line 14 upon responding to the input. Specifically, the body 20 in this embodiment is weakened such that it simply does not present resistance to the line 14 moving out of engagement therewith. The line 14 is no longer retained in the view of Figure 5 and thereby allowed to be displaced through the action of the element 12 expanding. This too allows the line to assume the position illustrated in Figure IB. Each of the parting embodiments referenced above are illustrated schematically by these views.

[0026] Referring to Figures 6-8. The body 20 is configured to respond to an input by weakening of the material of body 20. Figure 6 illustrated the body 20 prior to input whereby the line 14 is retained. After input, the body weakens or softens and will either stretch and deform to allow the line 14 to follow the expansion of element 12 or may simply rupture when the element 12 puts a load on the line 14. Each of the stretching or releasing embodiments referenced above are illustrated schematically by these views.

[0027] In a variation of any of the above discussed embodiments, the body 20 might be formed from thin struts instead of a full volume of material thereby allowing an even greater surface area contact with the body 20 and reducing tensile strength of the body to resist expansion loads from the element 12. Similarly, to enhance degradation or weakening of the body 20, it is contemplated that layers of material of body 20 be deposited at significantly different temperatures (for example 203 F* and 149 F*).

[0028] Referring to Figure 9, a line routing is illustrated. This routing creates excess line 14 in the vicinity of the expandable element 12 thereby allowing for that expansion without hinderance from the line 14 being retained. In this embodiment the line is retained in one part 24 of a clamp 26 and simply lightly restrained in the other part 28 thereof. Any of the clamp embodiments hereinabove may be used in this embodiment modified to provide the parts 24 and 28 functionality.

[0029] The tool 10 described herein may be run in open hole or in cased hole and where sensory function is desired the line 14 is caused by the actions of the clamp 16 and element 12 herein to come near or into contact with the inside diameter of the borehole 18 or the casing within that borehole 18. Further, the tool 10 is beneficially useful for hydraulic lines to protect the hydraulic line or the element from each other during the setting process.

[0030] Referring to Figure 10, a construction is illustrated that can be applied to any of the embodiments hereof. This is where a body 30 is a weakenable or degradable material but does not include a recess or at least not all of the recess. Rather, in this embodiment, the body 30 acts more like a gate and a portion of tool 10 acts as the recess 32. The line 14 is trapped in the recess 32 until the body 30 degrades enough to allow the line 14 to escape the recess 32 under the load created by the expanding element.

[0031] Referring to Figures 11 and 12, an alternate embodiment of control line clamp 40, that is employable on the tool 10, is illustrated in a line retained position and a line released position, respectively. The configuration 40 employs a clamshell 42 having a hinge pin 44 opposite a clamp body 46. Clamp body 46 retains the clamshell 42 in a closed position and traps the line 14 radially inwardly of the clamp body 46. A spring 48 is maintained in a compressed condition when the configuration 40 is in the line retained position. The clamp body 46 comprises a material similar to others of the disclosure hereof that degrades in response to environmental factors such as heat, fluids, time, etc. When the clamp body 46 is sufficiently degraded, it will release. Once the clamp body 46 releases, the clamp moves to the position illustrated in Figure 12 wherein the line 14 is released.

Referring to Figure 13, a borehole system 50 is illustrated. The system 50 comprises the borehole 18 in a subsurface formation 54. A string 56 is disposed within the borehole 18. A tool 10 as described herein is disposed as a part of the siring 56.
