Abstract
A downhole well tool comprises a seal ring secured along the outer surface of the downhole tool. The downhole tool expands the seal ring radially outward into sealing engagement with an outer tubular member in the well. The seal ring has an annular reinforcing element having an outer wall surface, an inner wall surface, and at least one hole disposed between the outer wall surface and the inner wall surface. At least one sealing material, either preformed or molded in place with the reinforcing element, is disposed along the outer wall surface, through each of the holes, and along at least a portion of the inner wall surface.
