Description:
EXPANDABLE ELEMENT CONFIGURATION, METHOD AND SYSTEM

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Application No. 17/384088, filed on July 23, 2021, which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] In the resource recovery and fluid sequestration industries, deploying elements to filter fluids and support wellbore structure is common. Some of the elements deployed include shape memory attributes. These work well in general but sometimes there are complications in determining volume and application method for activation fluids that result in excess engineering and preparation time. These issues can also sometimes result in longer well downtime, which is always undesirable. Therefore the art will well receive alternatives that improve efficiency.

SUMMARY

[0003] An embodiment of a shape memory material element configuration including a shape memory material element, and a capillary line extending to the element and positioned to apply an activation fluid to the element.

[0009] Figure 5 is the view of Figure 4 with the element expanded into proximity with the formation feature; and

[0010] Figure 6 is a view of a wellbore system including the shape memory material element configuration disclosed herein. DETAILED DESCRIPTION

[0011] 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.

[0012] Referring to Figure 1, a shape memory material element configuration 10 is illustrated. The configuration 10 includes a shape memory material element 12 and a capillary supply line 14 that may end at the element 12 or continue into the element 12. The shape memory material is, in an embodiment, a shape memory polymer and is a porous medium that act well as a filter. One example of a material that could form a portion of the element 12 is GeoForm shape memory polymer material commercially available from Baker Hughes, Houston Texas. The configuration 10 may also include end rings 16 to axially secure the element 12 and a manifold 18 in fluid communication with the line 14 and disposed within the element 12. As illustrated, the configuration 10 may be disposed upon a tubular 20 (that may be a part of a string in a borehole). The tubular 20 optionally includes one or more ports 22 through a wall thereof that fluidly connect an inside diameter surface of the tubular 20 with an outside surface of the tubular 20. In the embodiment as illustrated, the configuration 10 is located to be radially disposed relative to the ports 22 such that fluid transfer between a formation 24 outside of the element 12 and a fluid volume 26 inside of the tubular 20 is filtered by the element 12.

[0013] Regarding the line 14, in one embodiment where the line simply connects to the element 12, activation fluid injected through the line will either perfuse directly through the porous structure of the element 12 or may be distributed through the manifold 18. Manifold 18 is either formed by the material of the element 12 or made from another material and disposed within the element 12. The manifold 18 may be linear or branching or may simply be a bulbous void in the element 12, in embodiments. If the manifold 18 is of another material, then it is fluidly connected to the line 14 by suitable means. Where the manifold is another material, that material may be porous in nature or may have one or more openings therein to allow activation fluid injected through line 14 to reach and perfuse the element 12. This is illustrated in Figure 2. Once the element is perfused with the activation fluid, the element 12 expands as is illustrated in Figure 3.

[0014] A significant benefit of the presently disclosed configuration is that excess activation fluid is not required, as it would be in most downhole uses of shape memory material. Because a capillary line 14 is employed, activation fluid may be measured for volume at surface and injected directly to the element. No dilution of the fluid would occur like it would in other uses of shape memory material downhole where a pill is pumped, for example. Prior art methods for delivering activation fluid to a tool that uses a shape memory material all result in dilution of the activation fluid which then requires more fluid than actually needed for material shape change and tends to create other undesirable consequences in the borehole.

[0015] Referring to Figures 4, 5, and 6 a wellbore system 30 is illustrated. The system 30 includes a borehole 32 in the subsurface formation 24 (same as introduced above). A string 34 is disposed in the borehole 32. Disposed on the string is the configuration 10. It will be appreciated that the configuration 10 is disposed near the formation 24 with which fluid exchange is to occur. Upon the configuration reaching this illustrated location, the activation fluid is injected through line 14 to the element 12, whereby element 12 expands into close proximity or contact with the borehole 32. This condition is illustrated in Figure 5. Once the Figure 5 condition of the element 12 is achieved, fluid transfer from or too the formation 24 may commence while filtration through the element 12 is achieved.
