Abstract: Embodiments presented provide for an apparatus that provides a dislodgable plug seat that is used to capture a cement wiper plug for wellbore cementing operations. The apparatus further includes a collar having a ball seat and a closing sleeve configured to be shifted from an open position to a closed position. In the open position, a fluid pathway between an interior volume and a wellbore annulus is unblocked, and in the closed position the fluid pathway is blocked. A split ring is shiftable with the closing sleeve between a retained configuration when the closing sleeve is in the open position and an expanded configuration when the closing sleeve is in the closed position. The split ring holds the dislodgable plug seat in place within the body in the retained configuration and releases the dislodgable plug seat in the expanded configuration.

Abstract: Aspects of the present disclosure relate to a casing string comprising a buoyant mandrel and one or more dissolvable plugs, and methods of conducting wellbore operations using the casing string. The casing string may have an upper mandrel comprising a rupture disk. A slotted mandrel may be coupled to a lower end of the upper mandrel and comprise a plug disposed in a port of the slotted mandrel. A casing shoe may be coupled to a lower end of the slotted mandrel and comprise a check valve assembly. A gas filled chamber may be formed between the rupture disk and the check valve assembly. The plug may be configured to dissolve after a predetermined amount of time when in contact with a wellbore fluid.
