Disclosed herein is a swellable packer having a support element. A portion of the support element is substantially adjacent to the base tubular. Another portion of the support element is separated from the base tubular and a portion of the area between the support element and the base tubular is filled with the swellable material. Also disclosed herein is a sealing system including a packer as described above and a method for sealing within a wellbore using a packer as describe above.

Support tube for a swell packer, swell packer, method of manufacturing a swell packer, and method for using a swell packer

A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.

Swellable downhole device of substantially constant profile

A sealing member. The sealing member can include a support member having an inner bore and a plurality of apertures formed therethrough. An outer swellable element can be disposed about an outer diameter of the support member, and an inner swellable element can be disposed about an inner diameter of the support member. The swellable elements can be unitized with one another through each aperture. A retainer can be disposed at each end of the support member.
