Definitions

  • Swellable materials have been used to assist in setting seals or as seals themselves in various industries. Such materials are capable of generating a contact force against a nearby a structure which is capable of either of the noted uses of setting or sealing, or in some cases both, when exposed to a swelling fluid reactive with the swelling material.
  • Swelling can occur through absorption or chemical reaction.
  • difficulty has been experienced as sufficient volumetric change has not been reliably achievable and in addition when higher volumetric change is attempted, the material itself loses physical integrity thus compromising the ultimate goal of the application.
  • a swellable material seal includes a number of individual swellable material components configured as at least one of one or more primary elements and a plurality of backups; and spacing between the components sufficient to expose the swellable material to a swelling fluid.
  • a swellable material seal includes a quantity of swellable material disposed in a geometric configuration; and a plurality of openings in the material to enhance wettability thereof by a swelling fluid.
  • a method for creating a zonal isolation includes running a wellbore tool to depth, the tool having a quantity of swellable material thereon; exposing the swellable material to a swelling fluid; swelling the swellable material into contact with a separate structure.

  • FIG. 11 is a cross-sectional view of an ninth embodiment disclosed herein;
  • FIG. 12 is a cross-sectional view of a tenth embodiment disclosed herein.
  • one of the problems associated with higher volumetric expansions of sweliable materials is that the material itself when configured for use as an element such as an annular seal 10 for example, is bonded or otherwise mounted to a mandrel 12, generally in a way that reduces access of swelling fluid to the sweliable material.
  • the surfaces of an exemplary annular seal that are contactable by swelling fluid are an outside dimension surface 14 of the seal and end surfaces 16 and 18 at the axial ends of the seal.
  • An inside dimension surface 20 of the seal is relatively protected from contact with swelling fluid applied to the annular seal 10. This is due to whatever means has been used to mount the annular seal to the mandrel.
  • the exposed surfaces of the swellable material 14, 16, 18 must expand more significantly to achieve contact with an opposing structure (not shown) than they would have to have done if a greater proportion of the swellable material were "wettable" by the swelling fluid. More specifically, swelling would occur to a greater extent and more evenly if a greater percentage of the original volume of the material could be affected by the swelling fluid. Greater distribution of the swelling fluid throughout the volume of the swellable material increases the potential contact pressure generatable by the swellable material, and reduces spongyness of the swelled swellable material.
  • a swellable material as contemplated herein may be an elastomeric material such as rubber, for example, swelling EPDM, swelling Nitrile, etc.
  • fibrous material is embedded in the swellable material. This has two desirable effects. 1) The fibrous material provides a fluid pathway facilitating movement of the swelling fluid into an interior volume of the swellable material, thereby wetting areas of the volume otherwise insulated from the swelling fluid and, 2) the fibrous material lends mechanical strength to the swellable material, especially after swelling.
  • Fibrous materials contemplated for use herein include but are not limited Kevlar fiber, cotton fiber, etc. each of which have at least one of wicking properties and absorptive properties of for example water or oil. Other fibrous materials include but are not limited to hollow fiber, bicomponent fiber, etc.
  • Such tubes may be long or short or both and may also be used simply as conveyors that move fluid from one end to the other end, or may also be permeable along their respective lengths so that they supply swelling fluid along their lengths to the swellable material.
  • Each of the exemplary fibrous materials listed above also exhibits mechanical properties that enhance the strength of a swellable material into which they are embedded. Increasing the mechanical strength of the swellable material is desirable to improve extrusion resistance, among other things.
  • a first embodiment of the improved swellable material is illustrated in the form of an annular seal 110 mounted at an outside diameter of a mandrel 112. Fibrous material 130 is visible in the cross section of the seal 110. As will be evidenced from the drawing, the embodiment utilizes a random distribution of fibrous material 130 within the seal 110.
  • the fibrous material and swellable material of the seal 110 may be completely homogenously mixed or may be less so depending upon the desired level of homogeneity of swelling of the swellable material of the seal 110.
  • the fibrous material 130 may be of short fibers, long fibers or both as desired and may be mixed with the swellable material at a time prior to that material becoming relatively non-mixable in form.
  • the fibrous material 130 is mixed with the swellable material at a point in processing of the swellable material when mixing is possible and in one embodiment easiest to accomplish.
  • the fibrous material 130 acts to wick the swelling fluid into the volume of the swellable material to enhance the wettability of the swellable material and therefore the degree of swelling of the material.
  • FIG. 3 and 3a another embodiment of the improved swellable material is illustrated in the form of an annular seal 210 mounted at an outside dimension of a mandrel 212. Fibrous material 230 is visible in the cross section of the seal 210. It will be appreciated from the drawing figures 3 and 3 a that the distribution pattern of fibrous material 230 in the swellable material of seal 210 is in a layered format.
  • the layered format comprises individual fibers 232 laid axially of the element, and in one alternative embodiment comprises fibers grouped with a number of other individual fibers laid side-by-side and axially of the seal 210 as a pad 234.
  • the layout for this embodiment is best viewed in FIG. 3a where it is apparent that various groups of fibers are laid at differing radial distances from the inside dimension 220 of seal 210.
  • a third embodiment of the improved material illustrated in the form of an annular seal 310, is mounted at an outside dimension of a mandrel 312. Fibrous material 330 is visible in the cross section of seal 310 in FIG 3.
  • the fibrous material is arranged as a woven or non woven fabric.
  • Each bit of fabric embedded in the swellable material is about 0.25 in 2 or more.
  • the bits are embedded in a number of possible patterns some examples of which are illustrated in Figures 4b, 4c, 4d, 4e and 4f.
  • FIGS. 5 and 5a and 6 and 6a another embodiment of the improved swellable material is illustrated in the form of an annular seal 410 mounted at an outside dimension of a mandrel 412. Fibrous material 430 is visible in the cross section of the seal 410. It will be appreciated ftom the drawing figures 5 and 5a that the distribution pattern of fibrous material 430 in the swellable material of seal 410 is in a layered format. In this embodiment the distribution of a fibrous material is a woven or non woven fabric arranged frustoconically through the swellable material seal 410. TMs is best viewed in FIG. 5.
  • one or more frustoc ⁇ aes of fabric may be employed and that they may be arranged such that the frustocone angles outwardly as radial dimension from an axis of the element grows or angles inwardly as radial dimension from an axis of the element grows as in FIG. 5 or FIG. 6, respectively, or in any combination of FIGS. 5 and 6.
  • FIG. 7 another embodiment is illustrated very similar to the embodiment of FIG. 4 but utilizing corrugated fabric instead of planar fabric.
  • the swellable annular seal material 510 disposed upon mandrel 512 is configured to have a number of openings 550 therein.
  • the openings may be radially directed as shown or may have different angularity if desired or if useful for a particular application.
  • the openings 550 may be of any desired depth, including completely through the swellable material 510, and the greater the depth the greater the wettability of the swellable material.
  • the openings 550 are in a grid pattern. It is further noted that the density of the openings 550 may be greater or less than what is shown in figure 8.
  • openings 550 extend to the surface of the mandrel 512, but in addition, they are aligned with openings 560 in the mandrel itself. Where the openings 550 are aligned with openings 560, the openings 550 can be used as swellable material conduits once the swellable material has been swelled into contact with another structure. For example, where openings 550 are aligned with openings 560 and the "another structure" is the borehole wall (not shown), an isolated swellable material conduit directly from the mandrel to the borehole wall can be created upon swelling of the swellable material.
  • swellable material and the underlying mandrel opening 560 can be obtained by punching an opening in the swellable material either before or after applying the swellable material to the mandrel and then drilling the opening 560 through the mandrel in register with the opening 550. It is also possible to simply apply the swellable material opening 550 over an existing opening 560 in the mandrel 512.
  • openings 550 extending completely through the swellable material
  • openings 550 there are applications where it is desirable to extend the openings to close to the surface of the mandrel 512 but to not actually reach it.
  • the openings 560 will be sealed until a desired time when an appropriate diverter device allows pressure from a fluid to act on the swellable material from within the mandrel 512 and rupture the relatively thin material left in place over the opening 560.
  • swellable seal material 610 is illustrated.
  • This embodiment combines the concept of primary sealing structures and backup rings with swellable material construction and additionally with an understanding of exposed surface area of the swellable material. As has been clearly indicated hereinabove, causing the swellable material to be wettable improves the swelling characteristics thereof. Increasing the wettable surface area to volume ratio certainly increases the wettability.
  • the seal 610 is segmented into a primary seal 652, a set of cups 654 and a set of backups 656.
  • FIG. 12 is a reversed configuration of the concept a a gggp ⁇ where the center piece 752 acts as the backup, 754 are the cups and 756 an " di backups. d " b '
  • FIG. 12 While preferred embodiments have been shown and escn ed xi e " t modifications and substitutions may be made thereto without departing froi th spin and scope of the invention. Accordingly, it is to be understood that the present jravenfa ⁇ n has been described by way of illustrations and not limitation. «— - "
