Abstract: Embodiments of the present invention provide a process for manufacturing swellable packers with reinforcing fabrics and associated products used for sealing off chambers within well bores. According to one embodiment, the swellable packer is formed around a pipe by embedding a sheet of the reinforcing fabric within layers of a swellable polymer wrapped around the pipe. A sheet of reinforcing fabric is situated near each end of the swellable packer. Thus, as exposure to oil or water will cause the swellable packer to expand, the reinforcing fabric will initially retard swelling at the ends to allow for greater initial swelling along the center portion. The reinforcing fabric also strengthens the polymer to resist tearing or breakage caused by the flow of oil or water. A pair of swellable packers according to embodiments of the present invention can be placed on a pipe and placed within a bore and exposed to oil or water to create a pressurized chamber.
