Abstract:
A bridge plug includes a splayable assembly. The splayable assembly includes an upper annulus with upper extensions, a lower annulus with lower extensions opposing the upper annulus along an axis extending through the upper annulus and the lower annulus, and a linkage connecting the lower annulus to the upper annulus. The linkage has an upper link pivotably connected to a lower link, the upper link pivotably connected between circumferentially adjacent upper extensions and the lower link pivotably connected between circumferentially adjacent lower extensions. The elastic barrier sleeve extends circumferentially about the splayable assembly such that movement of the lower annulus towards the upper annulus expands the elastic barrier sleeve to form a barrier within a wellbore. Bridge plug arrangements and methods of emplacing bridge plugs in wellbores are also described.
