Abstract
Example systems, apparatus, and methods are described for providing continuous backup rings that are swaged into closed gland seal grooves to reduce extrusion of elastomeric sealing elements in packers. In an example embodiment, the closed gland sealing system includes a mandrel body having a cylindrical outer surface. A seal mandrel portion of the mandrel body is defined by an annular recess in the mandrel body that extends radially around the substantially cylindrical outer surface to form a closed gland groove. A sealing element is positioned in the closed gland groove and extends radially around the seal mandrel portion. Further, a continuous backup ring is positioned in contact with the sealing element in the closed gland groove that also extends radially around the seal mandrel portion.
