A bridge plug having a segmented backup shoe, and at least one split cone
extrusion limiter, the extrusion limiter comprising a two part conical
retainer positioned between packer elements and the segmented backup shoe
to block packer element extrusion though spaces between backup shoe
segments. In one embodiment, two split cone extrusion limiters are used
together and positioned so that each split cone extrusion limiter covers
gaps in the other extrusion limiter and together the two split cone
extrusion limiters block packer element extrusion though gaps between
backup shoe segments regardless of their orientation relative to the
segmented backup shoe. In one embodiment, a solid retaining ring is
positioned between a split retaining cone extrusion limiter and a packer
element and resists extrusion of packer elements into spaces in the split
cone extrusion limiter or limiters.
